The short answer

Editorial assessment

Knock2 compared with Vector

Vector is the other technically serious US person-level tool, oriented around contact-level intent and warm outbound. Knock2 is more explicitly an identification-plus-routing layer with published rates and an ungated feature set at $199. Both refuse to be enterprise ABM platforms, which is to their credit. Choose Vector if intent scoring across the buying group is the centre of your motion; choose Knock2 if the website visit itself is the trigger and you want the cheapest complete feature set.

Choose Knock2 if

US-focused B2B sales teams that want a named person and their buying committee in Slack within seconds of the visit, teams that already own a sequencer and want a clean identification layer feeding it, and buyers who want every feature available at the entry price rather than gated behind an upper tier.

Choose Vector if

US-focused B2B marketing teams for whom paid media is a primary channel, especially those already running LinkedIn and Google ads at meaningful spend who want to know who clicked, retarget identified people rather than lookalike guesses, and stop uploading static contact lists by hand.

Setup timeUnder five minutes for the script, per the vendor, plus perhaps an hour writing the ICP description and the routing rules. There is no tag manager configuration or per-platform integration.Roughly an hour for the Reveal plan: install the script, authorise the ad accounts and CRM you want synced, and connect Slack. Audience configuration is the part that takes thought, because a badly defined audience wastes media budget faster than it wastes anything else.
Learning curveLow. Plain-English ICP scoring removes the rule-building step that makes most competitors' configuration painful, and the routing builder keys on obvious fields. The only genuinely new concept for most buyers is buying-committee expansion, which changes how you think about a visit.Moderate, and higher than the simpler tools in this category. Vector assumes you understand matched audiences, retargeting mechanics, and B2B media buying. A team without a paid media practitioner will struggle to extract the value that justifies the price.

Strengths and limitations

Knock2

Strengths

  • Publishes match rates with a stated denominator (93 percent account-level and 62 percent person-level on engaged US sessions defined as ten seconds or two pageviews), which is more methodological honesty than this category usually offers.
  • Device-level matching across several consented identity graphs rather than reselling one provider, which is a genuine architectural reason for higher resolution.
  • Every feature on every tier: API, MCP, webhooks, all CRM and outbound connectors, buying-committee expansion, and AI scoring are available on the $199 plan.
  • Buying-committee expansion is the most useful feature here, because one anonymous researcher is rarely the buyer and three to five named influencers is an account plan.

Limitations

  • Person-level identification is US-only, which makes the headline capability irrelevant for European, UK, and most international sales motions.
  • The 93 percent claim is measured against engaged sessions rather than total traffic, so the number that appears on your invoice per thousand raw sessions will look much less impressive than the marketing figure.
  • No opt-out workflow or data broker registration is published, which will stall a serious privacy review.
  • No built-in sequencer or sending infrastructure, so you need a separate outbound tool; whether that is a limitation or a virtue depends on your stack.

Vector

Strengths

  • Ad Reveal is a genuinely differentiated feature: naming the people who clicked your ads and did not convert closes the most expensive blind spot in B2B paid media.
  • Automatic audience syncing into LinkedIn, Google, Meta, Reddit, and YouTube removes the quarterly ritual of exporting spreadsheets and uploading stale matched audiences.
  • Month-to-month billing on the entire self-serve Reveal ladder, in a category that has been drifting toward annual-only contracts.
  • Billing is on identified visitors rather than total traffic, so a poor match rate costs you less as well as delivering less.

Limitations

  • Coverage is heavily US-biased because of GDPR constraints in Europe, so a European or UK-heavy site will see a much thinner match rate than the marketing implies.
  • The published 45 percent match rate example sits well above the 15 to 30 percent contact-level coverage that independent reviews describe, so the headline figure should be treated as a best case rather than an expectation.
  • The flagship capability, signal-driven audiences that refresh themselves, sits on the Target plan at $3,000 a month with an annual commitment and a mandatory demo, which puts it outside small-business reach.
  • Entry pricing at $399 a month is high for a business without paid media spend, and the tool's value collapses without it.

Pricing compared

Knock2

Usage-based monthly subscription priced on identified contacts per month with an attached credit pool, month-to-month or annual, and every feature included on every tier.

  • Startup$199
  • Pro$349
  • Growth$499
  • Growth Plus$749
  • Scale$999

Per identified contact Knock2 is mid-market: more expensive than Happierleads at entry, far more expensive than RB2B's free tier, and comparable to Leadpipe once you account for what each returns. What you are paying the premium for is match rate and structure. If the 62 percent person-level figure holds anywhere near true on your US traffic, the effective cost per usable contact is lower than a cheaper tool with a thinner graph, because you are not paying for sessions that never resolve. The ungated feature set compounds that: a $199 subscription with API, MCP, buying-committee expansion, and every CRM connector is more product than several competitors sell at three times the price. The value case collapses if your traffic is not predominantly US, at which point you are buying an account-level tool at person-level prices.

Vector

Two products with different commercial models: Reveal is a self-serve month-to-month subscription priced on identified visitors per month, and Target is an annual commitment priced on the number of active audiences.

  • Reveal 2,500$399
  • Reveal 5,000$599
  • Reveal 7,500$799
  • Reveal 10,000$999
  • TargetFrom $3,000

Vector is expensive per identified visitor next to RB2B or Snitcher, and that comparison is the wrong one. What you are buying at $399 a month is not the identity, it is Ad Reveal plus automated audience activation across LinkedIn, Google, Meta, and Reddit, which nothing else in this price bracket does. For a team spending five figures a month on B2B paid media, knowing who clicked and being able to retarget those exact people is worth considerably more than $399, and the month-to-month billing lowers the risk of finding out. For a team spending nothing on ads, almost none of that value applies and the price is indefensible. The value question here is not about the tool, it is about whether you buy attention.

Editorial verdict on each

Knock2

Knock2 is the best-structured product in the US person-level end of this category, and the structure is the reason to buy it. Every feature on every tier, month-to-month billing, an API and an MCP endpoint at $199, match rates published with an actual denominator, and buying-committee expansion that turns a single anonymous reader into a workable account. If your traffic is predominantly US and you already own a sequencer, this is the identification layer to try first, and the seven-day trial will tell you within a week whether the economics work on your site. If you sell into Europe, the headline capability is switched off and you should be looking at Snitcher or Leadinfo. And understand what you are buying either way: the people Knock2 names consented to a publisher, not to you, and the vendor has not published how a visitor opts out.

Vector

Vector is the visitor identification tool for teams that answer intent with media rather than with people. Ad Reveal is the standout: naming the buyers who clicked an expensive LinkedIn ad and quietly left is something nothing else at this price does, and automated audience syncing kills the stale-spreadsheet ritual that makes most B2B matched audiences useless. At $399 a month month-to-month with a 14-day trial, the entry product is a defensible small-business purchase if you already spend meaningfully on ads. It is also US-weighted to the point of being the wrong tool for a European site, its published match rate looks optimistic against independent estimates, its privacy documentation is thinner than competitors', and the signal-driven audience capability that the marketing leads with lives on a $3,000-a-month annual plan behind a demo. Buy the Reveal tier if paid media is your channel and your buyers are American. If you do not run ads, almost none of this applies and you should be reading the RB2B or Snitcher profile instead.
