Store Leads vs TheirStack
An independent, review-free comparison compiled by the SaaSTracker editorial team. Both products are profiled in full, and neither can pay for placement here.
The short answer
Both sides assessedStore Leads compared with TheirStack
TheirStack infers what a company uses from its job postings, which is how you find internal tools that never appear on a website. Store Leads reads the storefront directly, which is how you find checkout, review, and loyalty apps that never appear in a job ad. For an ecommerce vendor Store Leads is the primary source and TheirStack is the supplement; for a back-office software vendor it is the reverse.
TheirStack compared with Store Leads
Store Leads reads storefronts and knows which apps a merchant installed and uninstalled last week. TheirStack reads job ads and knows what a company's engineering and operations teams run internally. There is essentially no overlap in what they see. Ecommerce vendors buy Store Leads; infrastructure and back-office vendors buy TheirStack; almost nobody genuinely needs both.
Choose Store Leads if
Shopify and WooCommerce app developers, ecommerce agencies, 3PL and shipping vendors, payment and checkout products, DTC-focused service businesses, and investment analysts who want alternative data on online retail.
Choose TheirStack if
Vendors selling back-office, infrastructure, or developer software whose product never appears on a customer's website, recruiters and staffing firms who need hiring signal at scale, and technical GTM operators who would rather hit an API or an MCP server than click through a dashboard.

| Category | Signals | Signals |
| Starting price | $75 per month (Premium) (free plan available) | Free tier on signup, then $49 per month for 1,500 credits or $109 once for 1,000 credits (free plan available) |
| Pricing model | Flat monthly or annual subscription by plan, gated on platform coverage, search volume, export and API access, and seats; extra seats billed separately. | Credit-based, sold either as a monthly subscription or as one-time packs with no subscription; unlimited team members and no per-seat charge. |
| Free plan | Limited free search and store lookup on the website plus the Chrome extension, without export, API, or full attribute access. | Free credits on signup with access to job search, company search, company lookup, enrichment, exports, and email alerts, at low volume. |
| Free trial | Not published as a fixed-length trial; the free search preview and Chrome extension serve as the evaluation path | Not a time-limited trial; a free credit allowance is included on signup |
| Best for | Shopify and WooCommerce app developers, ecommerce agencies, 3PL and shipping vendors, payment and checkout products, DTC-focused service businesses, and investment analysts who want alternative data on online retail. | Vendors selling back-office, infrastructure, or developer software whose product never appears on a customer's website, recruiters and staffing firms who need hiring signal at scale, and technical GTM operators who would rather hit an API or an MCP server than click through a dashboard. |
| Setup time | Under an hour to a first useful list. Sign up, pick your two platforms, apply filters on platform, geography, sales estimate, and installed apps, and export. Wiring alerts and a CRM push is another afternoon. | Twenty minutes to a first list. Sign up, spend free credits on a query against your best-guess ICP, and read the source postings to see whether the extraction is catching what you expected. API integration is another afternoon. |
| Learning curve | Low. The filter interface is clear, the attribute names mean what they say, and the documentation explains the estimates. The genuine skill is picking thresholds that separate real businesses from hobby stores, which takes a couple of iterations. | Low for the app, moderate for the judgement. The filters are straightforward; the skill is learning which technology mentions actually indicate ownership rather than aspiration, and building filters that exclude recruitment agency postings. |
| Platforms | Web application, REST API, Chrome extension, CSV export | Web application, REST APIs for jobs, companies, technographics, and buying intents, MCP servers, CSV export |
| Compliance | Stores non-personal business contact data only, which materially narrows GDPR exposure, No publicly advertised SOC 2 attestation | Job posting data is published business information rather than personal data, which keeps privacy exposure low, No publicly advertised SOC 2 attestation |

Strengths and limitations
Store Leads
Strengths
- Dated app install and uninstall records refreshed weekly are one of the cleanest buying signals available anywhere: an uninstall means an unsolved problem, right now, at a named store.
- Coverage of roughly 13.8 million active stores across 410-plus platforms is the most complete ecommerce index a small business can actually buy.
- Weekly refresh across the entire database, rather than opportunistic recrawling, means the worst-case staleness is measured in days rather than months.
- Estimated app spend is a better qualification filter than revenue, because it directly measures willingness to pay for software.
Limitations
- Ecommerce only. There is no coverage of B2B software companies, services firms, or anything without an online store, which rules out most of the market.
- The two-platform cap on Premium and Pro is easy to miss when comparing prices and is the most common reason buyers end up on a more expensive plan than they budgeted.
- No CSV export or API on the $75 plan makes the advertised entry price misleading as a working cost.
- Revenue and app spend are modelled estimates. They are good enough for segmentation and wrong often enough that quoting them back to a merchant on a call is risky.
TheirStack
Strengths
- The job posting source sees software that no website crawler ever will, which makes TheirStack the only practical technographic option for back-office, data, and infrastructure vendors.
- Every extracted signal links back to the source posting, so claims are verifiable rather than a black box, and a rep can quote the actual requirement on a call.
- Ingestion of roughly 300,000 postings a day means the freshness ceiling is about a day, far better than the weekly or opportunistic crawls elsewhere in this category.
- The API is included in the same credit balance as the app rather than priced separately, and MCP servers are available, which is a genuinely developer-friendly posture at this price.
Limitations
- Everything is inference. A technology mentioned in a posting is strong evidence, not proof, and companies routinely list tools they are migrating away from, tools a single team uses, and tools copied from a stale template.
- Companies that do not advertise roles publicly are effectively absent, which skews coverage toward larger and faster-growing organisations and away from small established businesses.
- Recruitment agency postings are a persistent noise source: the hiring company in the record may be the agency rather than the end employer, and filtering that out takes deliberate work.
- No storefront or consumer-web technographics, so ecommerce app vendors get nothing useful here.
Pricing compared
Store Leads
Flat monthly or annual subscription by plan, gated on platform coverage, search volume, export and API access, and seats; extra seats billed separately.
- Premium$75
- Pro$250
- Elite$450
- Enterprise$950
Model it at two volumes. A solo app developer on Pro at $250 who exports 3,000 targeted merchants a month is paying roughly 8 cents a record for data that includes dated app installs, revenue estimates, and app spend, which no general contact database can produce at any price. An agency on Elite at $450 pulling 40,000 rows across every platform is at roughly a cent a record. Both are good. The bad deal is Premium at $75, where the absence of export means you cannot actually use what you are paying for; treat it as a $75 research subscription and nothing more. Add a contact vendor on top and the true cost of a working motion is closer to $350 to $600 a month than the headline $75.
TheirStack
Credit-based, sold either as a monthly subscription or as one-time packs with no subscription; unlimited team members and no per-seat charge.
- Free$0
- Monthly API subscription, entry$49
- Monthly API subscription, mid$169
- Monthly API subscription, high volume$400
- One-time credit packs$109
Model it at two volumes. A founder validating a market buys the $109 one-time pack, pulls 1,000 company records with their inferred stacks, and never pays again; at roughly 11 cents a record that is cheap for data nobody else has. A vendor running continuous outbound sits on the $169 monthly plan for 10,000 credits, or around 1.7 cents a credit, and pulls a few thousand qualified companies a month with the API doing the work. At $400 for 50,000 the unit cost falls under a cent. The pricing is the most honest in the category: no seats, no separate API bill, no annual lock-in, and a free tier that actually lets you check whether your buyers appear in job ads before you spend anything.
Editorial verdict on each
Store Leads
Store Leads is the best value in this whole category if and only if your customers sell things online. The weekly refresh, the dated app install and uninstall records, and the estimated app spend give you a qualification stack that no general database can match, and unmetered exports mean the cost per record collapses once you are actually using it. Buy Pro at $250 if you sell into one or two platforms, or Elite at $450 if you are platform-agnostic, and budget another hundred or two for a contact vendor because Store Leads will not give you named humans. Skip Premium at $75: without export it is a research subscription wearing a prospecting plan's clothes. And be ruthless about the fit question, because outside ecommerce this product has literally nothing to say.

TheirStack is the best-priced serious signal tool in this category and the only sensible option if the software you sell lives somewhere a crawler cannot reach. Reading job ads rather than websites is not a clever workaround, it is a structurally better view of a company's internal stack, and 300,000 new postings a day gives it a freshness advantage that weekly-crawl vendors cannot close. Buy the $109 one-time pack first and check whether your buyers actually post job ads, because if they do not, nothing else about the product matters. If they do, the $169 monthly plan with unlimited seats and the API included is a genuinely cheap foundation for an account-selection motion. Just build the verification habit early: this is inference, every record links to the posting it came from, and the teams that read the source before dialling get very different results from the ones that trust the label.
