Write the signal in plain English, get the answer every morning with the quote attached
WhiteWhale is a custom buying signal platform that lets a sales team write up to about thirty-five signal definitions as plain-English yes or no questions, then checks every account on its list against news, press releases, live applicant tracking system job postings, earnings calls, SEC filings, company websites, and company social posts once a day, scores accounts by how many signals are stacking, and pushes the result with a short why-now summary and its source quotes into Slack, HubSpot, Salesforce, Clay, Outreach, or a webhook; it is bootstrapped, starts at $200 a month with unlimited seats, and requires no annual contract.
Overview
Most signal tools hand you a fixed menu. You can trigger on funding, hiring, a technology change, or a job move, and if the event that actually predicts a deal in your business is not on the list, you are out of luck. WhiteWhale inverts that. You write the questions yourself, in ordinary language, and the platform answers them for every account on your list every day. Did they hire a new chief revenue officer. Are they consolidating vendors. Are they migrating off a legacy CRM. Are they expanding into Europe. Up to about thirty-five questions, each one specific to how your product actually gets bought.
The company was founded in mid-2024 by two founders who met at the University of Michigan's Ross School of Business, and it is bootstrapped with no venture capital. It describes itself as profitable and lean, and reports more than 715 sellers using the product. In a category where the recognisable names have raised tens of millions and price accordingly, a self-funded two-person operation charging $200 a month is a genuinely different proposition, with the usual trade: no procurement machinery, no compliance library, and a support bench measured in people you could name.
The design decision that says the most about the product is this one, stated openly by the vendor: ninety percent of users never log in, by design. WhiteWhale is not trying to be a dashboard you check. Signals leave the platform and land in Slack, the CRM, a Clay table, a sequencer, or your own endpoint through the API, each one carrying a two or three sentence explanation of what changed and why it is worth reaching out today, with the underlying sources attached so a rep can verify the claim before writing.
Pricing is self-serve and published. Starter is $200 a month monitoring 300 accounts weekly with self-guided onboarding, unlimited signal suggestions, unlimited seats, and all integrations. Growth is $500 a month monitoring 750 accounts weekly and adds dedicated onboarding plus closed-won signal backtesting, which lets you test a proposed signal against deals you already won. There is a free preview that shows your signals without a credit card, and no annual commitment on either tier.
Best for
Outbound sales teams with a defined account list and a specific, unusual trigger that no packaged signal library covers, teams selling into public companies where filings and earnings calls carry real information, and small businesses that want signal monitoring delivered into Slack and the CRM for a couple of hundred dollars a month with no annual contract.
Not the right fit for
- Teams without a target account list. WhiteWhale monitors accounts you nominate, so it cannot find new accounts you have never heard of and is not a prospecting database.
- Anyone who needs website visitor identification or product usage signals. Every source here is external and public; the platform sees nothing about your own site or product.
- Buyers who want person-level signals such as a specific champion changing jobs. Monitoring is account-level, and a leadership change surfaces because it was announced, not because an individual profile was tracked.
- Companies selling into small private businesses that publish nothing. If your accounts have no news coverage, no filings, no earnings calls, and no job postings, there is nothing to read and the daily check returns silence.
- Enterprise buyers who need a vendor with a compliance library and a procurement process. This is a bootstrapped company founded in 2024 with two founders, and a security review will not go smoothly.
How it works
- 1
You supply an account list and write your signals. The recommended starting point is ten to fifteen custom questions tied to your ideal customer profile, each phrased as a yes or no question rather than a keyword. WhiteWhale will help configure the initial set if you would rather describe the motion than write the questions cold.
- 2
Every day the platform checks each account against its sources. News and press releases, job postings pulled live from applicant tracking systems including Greenhouse, Lever, and Workday, earnings calls, SEC filings, company websites, and company social posts are all read to answer your specific questions rather than to produce a generic feed.
- 3
Answers are scored by stacking. An account triggering one signal is interesting; an account triggering four in the same week is a priority, and the ranking reflects that rather than treating every event as equal. Each hit carries the source material behind it, so a claim can be checked rather than trusted.
- 4
The signal then leaves. A why-now summary of two or three sentences explains what changed and why it matters, and that package routes into Slack, Microsoft Teams, HubSpot, Salesforce, Clay, Outreach, Google Calendar, or your own endpoint by API or webhook, plus an MCP connection for AI assistants. Nobody has to open the product for it to work.
Feature breakdown
26 features in 5 modulesCustom signal definitions
The idea the whole product rests on.- Plain-English signal writing
- Signals are written as yes or no questions in ordinary language rather than picked from a fixed library or built as Boolean strings, which means the trigger can be as specific as your sales motion actually is.
- Up to about thirty-five custom questions
- The practical ceiling on signal definitions, with a recommended starting set of ten to fifteen tied to the ideal customer profile so the output stays interpretable.
- Assisted configuration
- The team will help write the initial signal set, and Growth includes dedicated onboarding, which matters because signal design is the part most teams get wrong.
- Unlimited signal suggestions
- Included on both plans, so iterating on wording and adding new questions is not a metered activity that discourages experimentation.
- Closed-won signal backtesting
- On the Growth tier, a proposed signal can be tested against accounts you have already closed, which turns signal selection from a hunch into evidence.
Sources and evidence
Where the answers come from, and why you can trust them.- Live applicant tracking system job postings
- Roles are pulled from Greenhouse, Lever, and Workday directly rather than from aggregated job boards, which gives cleaner data and earlier detection than scraping a job site.
- SEC filings
- Regulatory documents are read for the signals you defined, which is a source almost no tool at this price monitors and a strong one for anyone selling into public companies.
- Earnings calls
- Transcripts are checked for your questions, so a stated strategic priority on a call becomes a trigger rather than something a rep would have had to read for themselves.
- News and press releases
- The conventional event layer covering funding, launches, partnerships, expansion, and leadership changes.
- Company websites and social posts
- Company-published content is monitored, which catches quieter changes that never reach a press outlet, such as a new product page or a positioning shift.
- Source quotes attached
- Every triggered signal carries the underlying material, so a rep can verify the claim before writing rather than repeating something the tool asserted.
Scoring and summaries
Turning a set of yes answers into a priority order.- Signal stacking scores
- Accounts are ranked by how many of your signals are firing simultaneously, on the premise that four converging events mean far more than one, which is a simple and defensible model.
- Why-now summaries
- A two or three sentence explanation connects multiple data points into a narrative a rep can actually open a message with, rather than leaving them to interpret raw events.
- Daily monitoring cadence
- Every account on your list is checked against every signal each day, so the freshness is a known quantity rather than an unstated crawl schedule.
- Account-list scope
- 300 accounts monitored weekly on Starter and 750 on Growth, which is the real capacity constraint and the number to size your target list against.
Delivery and integrations
Built on the assumption that nobody wants another tab.- Slack and Microsoft Teams
- The primary destinations, where the why-now summary and its sources land for the owning rep.
- CRM sync
- HubSpot and Salesforce connectors write signals against the account record so context sits with the deal.
- Clay integration
- Signals can flow into a Clay table, which lets a technical team blend WhiteWhale's custom answers with other enrichment before deciding what to do.
- Outreach and sequencer routing
- Triggered accounts can be pushed toward the sequencing tool where the outreach actually happens.
- Sales signals API and webhooks
- A published API and webhook support push signals into any system, including your own internal tooling.
- MCP connector
- An assistant connection so Claude and similar tools can query the signal set directly, which fits the way small teams increasingly work.
- Unlimited seats on every plan
- Included from the $200 Starter tier, so the whole team can receive signals without the per-seat maths that inflates competitors' bills.
Commercial model
Self-serve, published, and short-committed.- Free signal preview
- See your signals without a credit card before committing, which is the evaluation path the vendor points people at.
- No annual contract
- Both published tiers are month to month, which is unusual for a tool that monitors a named account list.
- All integrations on every tier
- The connector set is not used to force upgrades; the difference between Starter and Growth is account volume, onboarding, and backtesting.
- Bootstrapped and profitable
- No venture capital, which means no investor pressure to move upmarket and abandon two hundred dollar customers, though it also means a very small team.
Use cases
4 documentedSales team selling into public companies
The best deals all followed a specific statement on an earnings call, but nobody has time to read transcripts for four hundred accounts every quarter.
A plain-English signal asks the question directly, earnings calls and filings are checked daily, and the rep gets a Slack message with the relevant quote and a why-now summary the same week the call happens.
Founder with an unusual buying trigger
Their product only makes sense when a company is consolidating vendors after an acquisition, and no signal platform on the market has that as a category.
The trigger is written as a question rather than selected from a menu, and three hundred target accounts are checked against it every day for $200 a month.
Small outbound team drowning in generic intent data
An intent subscription reports that forty accounts are surging every week with no explanation of what happened, and reps have stopped believing it.
Signals arrive with a source quote and a two-sentence reason, so reps can verify the claim and open with something specific instead of pretending they noticed a surge score.
Revenue operations lead validating a signal thesis
Leadership wants to build a triggered motion but nobody can say which triggers preceded the deals the company already won.
Growth-tier closed-won backtesting runs proposed signals against historical wins, so the motion is built on the triggers that actually correlated rather than the ones that sound plausible.
Pricing
from $200 per month (Starter)Self-serve monthly subscription priced by the number of accounts monitored, with unlimited seats and all integrations on every tier.
| Plan | Price | Includes |
|---|---|---|
| Starter | $200 per month |
Sized for a focused target list rather than a database. Three hundred accounts is the constraint to plan around. |
| Growth | $500 per month |
Backtesting is the reason to step up, more than the extra account capacity. |
Billing notes
- Both tiers are month to month with no annual contract, which is rare for account-monitoring tools that usually want a year.
- Pricing is by accounts monitored rather than by seat or by credit, so the cost of acting on a signal is zero at the margin.
- All integrations are included on both plans, so connector access is never the reason to upgrade.
- The account cap is weekly monitoring capacity, so a target list larger than 750 accounts needs a conversation rather than a self-serve tier.
- The free preview shows your signals before payment, which is a more useful evaluation than a time-limited trial of a tool you have not configured.
Value assessment: At $200 a month with unlimited seats and no annual contract, WhiteWhale is priced like a small tool and behaves like a research team. The differentiator is not volume, since three hundred accounts is a modest list, but specificity: nobody else at this price will read SEC filings and earnings call transcripts to answer a question you wrote yourself. The value is highest when your buying trigger is genuinely unusual and lowest when it is not, because if your signal is simply funding or hiring then cheaper API-based data covers it. The other real value item is Growth's closed-won backtesting at $500, which is the only feature in this batch that tells you whether your signal thesis was ever true.
Strengths & limitations
Strengths
- Custom plain-English signals mean the trigger can match your actual sales motion instead of the vendor's category list, which is a structural advantage no fixed signal library can match.
- Source quotes attached to every hit, so reps verify rather than trust, which is the difference between a signal tool people use and one they quietly ignore.
- SEC filings and earnings call transcripts as monitored sources, which almost nothing else at this price reads and which matter enormously if you sell to public companies.
- Job postings pulled live from Greenhouse, Lever, and Workday rather than scraped from aggregators, giving cleaner and earlier hiring signals.
- Signals leave the platform by design, with Slack, CRM, Clay, Outreach, API, webhook, and MCP delivery, so nobody is required to log in for the product to work.
- Unlimited seats and all integrations on the $200 tier, with no annual contract, which is an unusually honest commercial structure.
- Bootstrapped and profitable with no investor pressure to abandon small customers, which in this category is a meaningful stability argument.
Limitations
- You must bring the account list. WhiteWhale monitors accounts you nominate and cannot surface companies you have never considered.
- Account caps of 300 and 750 weekly are small, so this suits a focused named-account motion rather than broad market coverage.
- Every source is external and public, so there is no visibility into your own website traffic, product usage, or email engagement.
- Signals are account-level, so a champion changing jobs only surfaces if it is publicly announced rather than through individual profile tracking.
- Signal quality depends entirely on how well you write the questions, and a vague question produces vague answers at daily frequency.
- Founded in mid-2024, bootstrapped, and run by two founders, which means limited compliance documentation, a thin support bench, and real key-person risk.
Head-to-head comparisons
3 alternativesWhiteWhale vs RB2B
from $0 (Free), then $79 per month (Starter)RB2B watches your own website and tells you which named person from a United States company just visited, for $149 a month. WhiteWhale watches the outside world and tells you which of your target accounts just did something that matches a question you wrote. Neither substitutes for the other: RB2B captures demand that already found you, WhiteWhale creates a reason to reach accounts that have not. A small team with inbound traffic should start with RB2B; a team with a named account list and no inbound should start with WhiteWhale.
Full WhiteWhale vs RB2B comparisonWhiteWhale vs Wappalyzer
from $0 (Free), then $250 per month (Pro)Wappalyzer owns one signal type deeply, technology installs and stack changes, with a free tier and a $250 a month Pro plan. WhiteWhale owns whichever signals you can describe in a sentence, including technology migrations, but reads news, filings, and job postings rather than scanning code. Take Wappalyzer if the trigger is genuinely a technology appearing or disappearing on a site; take WhiteWhale if your triggers are varied and human, and accept that it will not detect a silent script swap.
Full WhiteWhale vs Wappalyzer comparisonWhiteWhale vs Clay
from Free plan; paid from $149/moClay gives you a hundred and fifty data providers and a table to combine them in, which means you can build almost any signal if you are willing to design and maintain it. WhiteWhale writes the signal for you and delivers the answer with its evidence for $200 a month flat. Teams with a go-to-market engineer will get a higher ceiling from Clay; teams without one get a working custom signal motion far faster from WhiteWhale, and the two integrate rather than compete.
Full WhiteWhale vs Clay comparisonImplementation & onboarding
- Setup time
- A few days rather than a few minutes. Uploading the account list and connecting Slack is quick, but writing ten to fifteen signal questions that produce useful answers takes a couple of iterations, and the vendor offers help precisely because that step is where value is won or lost.
- Learning curve
- Conceptually easy, practically subtle. Anyone can write a question; writing a question that is specific enough to avoid noise and broad enough to fire more than twice a year is a craft. Expect to rewrite half your signals after the first fortnight of results.
- Onboarding
- Self-guided on Starter and dedicated on Growth, with a free preview of your signals before any payment. Both published tiers are self-serve and month to month.
- Migration notes
- Nothing to migrate in beyond your account list, which is usually a CRM export. There is no historical archive to lose on the way out because signals are pushed into your CRM and Slack as they happen, so the record lives in your systems rather than the vendor's. Signal definitions themselves do not transfer to another vendor, since no competitor accepts plain-English questions in the same way.
Platform, API & security
- Platforms
- Web applicationSlack and Microsoft Teams appsSales signals APIWebhooksMCP connector
- API
- A published sales signals API plus webhook support pushes triggered signals into any destination, and an MCP connector exposes the signal set to AI assistants such as Claude.
- Compliance
- Sources are public: filings, news, job postings, earnings calls, and company-published contentNo publicly advertised SOC 2 attestation
- Data residency
- Not published. A bootstrapped company of this size will not typically offer residency options.
- SSO
- Not advertised on the published tiers.
- Security notes
- The data WhiteWhale processes is drawn from public company sources rather than personal identity graphs, which keeps the privacy profile low. The sensitive item is your target account list, which tells the vendor exactly who you are selling to, so treat that as commercially confidential information leaving your systems.

Frequently asked questions
10 questionsWhat is WhiteWhale?
WhiteWhale is a custom buying signal platform. You write up to about thirty-five signal definitions as plain-English yes or no questions, and it checks every account on your list against news, press releases, live applicant tracking system job postings, earnings calls, SEC filings, company websites, and company social posts once a day, then pushes the hits with a why-now summary and source quotes into Slack, your CRM, Clay, a sequencer, or your own endpoint.
How much does WhiteWhale cost?
Starter is $200 a month and monitors 300 accounts weekly with unlimited seats, unlimited signal suggestions, all integrations, and self-guided onboarding. Growth is $500 a month, monitors 750 accounts weekly, and adds dedicated onboarding plus closed-won signal backtesting. Both are self-serve with no annual contract, and there is a free preview of your signals with no credit card.
Which signals does WhiteWhale own?
Whichever ones you write, within the sources it reads. Those sources are news and press releases, job postings pulled live from Greenhouse, Lever, and Workday, earnings call transcripts, SEC filings, company websites, and company social posts. That covers leadership changes, hiring patterns, funding, product launches, expansion, vendor consolidation, and stated strategic priorities. It does not cover your website traffic, your product usage, or individual person-level job moves.
How fresh are the signals?
Every account on your list is checked against every one of your signals once a day, which is a published cadence rather than an implied one. Job postings come live from applicant tracking systems rather than aggregated job boards, so a new role typically surfaces earlier than it would through a scraped job site.
How does WhiteWhale handle false positives?
Three ways. Signals are yes or no answers to questions you wrote, which is narrower than a keyword match or a surge score. Every hit carries the source material, so a rep can check the claim in seconds rather than acting on an assertion. And scoring is based on stacking, so an account firing four signals in a week ranks above one firing a single ambiguous event. The remaining risk is on you: a vaguely worded question will produce vague hits every day.
Does WhiteWhale end at a dashboard?
Deliberately not. The vendor states that ninety percent of users never log in, by design. Triggered signals are pushed to Slack, Microsoft Teams, HubSpot, Salesforce, Clay, Outreach, Google Calendar, an API, a webhook, or an MCP connection, each carrying a two or three sentence why-now summary. What it does not do is send the message itself, so your sequencer remains the sending layer.
What does it cost to act on a signal?
Nothing at the margin, which is unusual in this category. Pricing is by accounts monitored rather than by credits or seats, so there is no per-signal charge, no enrichment meter, and no per-user fee. The constraint is the size of the monitored list: 300 accounts on Starter and 750 on Growth. If your list is larger than that, the plan is the limit rather than your usage.
Can I test whether my signals actually predict deals?
Yes, on the Growth tier at $500 a month, through closed-won signal backtesting. Proposed signals are run against accounts you have already closed to see whether the trigger genuinely preceded the win. This is the single most valuable feature in the product for anyone building a triggered motion, because it converts signal selection from an argument into evidence.
Do I need my own account list?
Yes, and this is the main structural limit. WhiteWhale monitors accounts you nominate rather than discovering new ones, so it complements a prospecting database rather than replacing it. If you have no defined target list, build one first, because the product has nothing to monitor until you do.
Who is behind WhiteWhale and is it stable?
It was founded in mid-2024 by two founders who met at the University of Michigan's Ross School of Business, and it is bootstrapped with no venture funding. The company describes itself as profitable, lean, and serving more than 715 sellers. That means no investor pressure to abandon small customers, and equally it means a very small team, limited compliance documentation, and genuine key-person risk. Buy it for the product, not for the institutional durability.
Editorial verdict
WhiteWhale solves the problem every other tool in this category creates: the signal that actually predicts your deals is usually not on the vendor's menu. Writing triggers as plain-English questions and having them answered daily against filings, earnings calls, live job postings, and news, with the source quote attached, is a genuinely different product, and $200 a month with unlimited seats and no annual contract is a fair price for it. Buy it if you have a named account list and a specific, awkward trigger that no signal library covers, and pay the extra for Growth if you want to backtest your signals against deals you already won, which is the most honest feature in this whole category. Do not buy it as a prospecting tool, as a website intelligence tool, or as a person-level tracker, none of which it is. And go in clear-eyed about the vendor: two founders, bootstrapped, founded in 2024, which is the right risk for a $200 monthly experiment and the wrong risk for a system of record.
