Capix
Capix is an AI sourcing platform for private market professionals. It turns plain-English queries into structured company lists, continuously enriches profiles from public sources, and surfaces decision-maker contacts. Access currently runs through a private beta.
What is Capix?
Capix is a private market data intelligence platform built on one idea: describing what you are looking for should replace filling in filters. The home page calls it an autonomous sourcing copilot, and the product works by taking a request written in ordinary English and returning a structured, reusable dataset of matching companies and people. The example the site uses is finding cybersecurity companies that raised a Series A in the last six months, employ more than twenty people, and use Stripe for payments.
Underneath sits what the company's launch post of 3 August 2025 calls neural search. AI research agents visit sources, click through pages and extract what they find, continuously and several times a day, across millions of private companies. The sources named by Capix include company websites, investor reports, job postings, government filings, blog posts, LinkedIn profiles and proprietary databases. The result is described as living profiles rather than static records, and firm profiles carry contact information for decision-makers.
Coverage advertised as available today spans private equity firms, limited partners, private companies and public companies. Four use cases are put forward: investment banks and M&A teams building buyer lists and matching sell-side mandates; sales and revenue teams identifying accounts and stakeholders; market research such as sector analysis and benchmarking; and investors looking for funds or companies by strategy and positioning. Existing data can be brought in as well, with customers uploading a CRM export, a list or a spreadsheet that Capix then enriches by filling gaps and adding dimensions. Teams can also define proprietary datasets and their own sourcing logic.
Alongside the software, Capix sells managed services: analyst-vetted lists of 100 to 400 company records delivered within 48 hours, full deal sourcing with multi-touch outreach and booked calls, and expert research delivered as transcripts, datasets and findings.
The product is not openly available. It runs as a private beta with limited spots, entered by requesting an invitation and scheduling a demo. Capix, Inc. is based in New York and went through Y Combinator's Summer 2022 batch.

How to use Capix
A typical end-to-end flow, from setup to results.
- Open capix.ai and use the Get Access or Try Capix button to open the invitation form
- Complete the request form, answer the qualifying questions and schedule the demo call
- Wait for an invitation, since the beta runs with a limited number of spots
- Agree the plan, seat count, term and fees, which the Terms set out in an individual Order
- Sign in to the web application: there is nothing to install and no API key to configure
- Describe the companies or people you are looking for in plain English rather than setting filters
- Review the dataset Capix returns and refine the criteria until the list matches the mandate
- Open the company profiles to read the aggregated signals and the decision-maker contact details
- Upload an existing CRM export, list or spreadsheet to have records enriched and columns added
- Save the dataset and its sourcing logic so it keeps refreshing, or hand the work to the managed service described on the Services page
Pros & Cons
Pros
- Plain-English queries remove the rigid filter grids that traditional databases impose
- Profiles are re-enriched continuously rather than sitting in a static, ageing database
- Signals from many source types are reconciled in one place instead of being pieced together by hand
- Decision-maker contact details ship with the company records, not as a separate purchase
- Existing CRM exports and spreadsheets can be enriched rather than replaced
- Managed services are available for teams that would rather not operate the tool themselves
- The Terms of Service are dated, readable, and promise 15 days' notice before material changes
Cons
- Access is invitation-only through a private beta, with no self-service sign-up
- No pricing is published, and neither a free plan nor a free trial is announced
- No API and no developer documentation, so nothing can be automated from outside
- Capix publishes no privacy policy of its own: the footer link points to the Terms of Service
- The legal pages served on the domain are an unadapted website template written for another company
- Data hosting locations, subprocessors and any training opt-out are all undocumented
- Beta features are supplied as-is and fall outside the functionality warranty of section 7.3
Pricing & Plans
Capix publishes no price. There is no pricing page on the site, and neither a permanent free plan nor a free trial is announced. The Terms of Service state that fees, currency, term and seat caps are set individually in an Order, that plans bill annually and renew automatically unless the Order says otherwise, and that sales, VAT or GST taxes are charged in addition. A figure can therefore only be obtained by requesting an invitation and going through a demo call.
Data, GDPR & hosting
A consolidated view of how Capix handles your data.
GDPR overview
The GDPR appears in Capix's Terms of Service, but never as a compliance claim. Section 4.4 requires a Data Processing Agreement to be in place whenever the customer submits personal data covered by the GDPR, and states that the DPA prevails in case of conflict. Section 4.5 lists GDPR special categories among the prohibited data that must not be uploaded, and section 4.3 commits the vendor to applicable data protection laws for any personal data it handles. Beyond those three mentions, implementation is undocumented: Capix publishes no privacy policy of its own, names no Article 27 EU representative and no data protection officer, discloses no subprocessor list and no hosting location. The footer links labelled Privacy Policy and Terms of Use both point to the same Notion page, which is a service contract.
Who owns the data?
Ownership is split in the Terms of Service dated 2 October 2025. Capix keeps all rights to the Service, its software and related intellectual property, while the customer keeps all rights to the Customer Content it submits, subject to the licence granted in the Terms, and remains responsible for that content's accuracy and legality. Capix processes Customer Content only to provide and maintain the Service. Feedback given to the vendor may be used freely, and Usage Data is disclosed to third parties only in aggregated or de-identified form. Section 13 additionally lets Capix name the customer and use its name and logo in marketing.
Reuse rights
The Terms grant a non-exclusive, non-transferable right to access and use the Service for the customer's own internal business purposes during the subscription period, and nothing wider. The acceptable-use clause forbids sublicensing, reselling, renting or sharing access beyond the purchased seat cap, and forbids using the Service to build a competing service. No clause authorises customers to redistribute, republish or resell the company records the platform surfaces, so any reuse outside the buying organisation should be cleared with Capix first. Content the customer uploads for enrichment stays its own, and the vendor commits to processing it only to run the Service.
Data retention & training
Hosting summary
Capix does not say where customer data is hosted. Its Terms of Service, the only legal document the company publishes, contain no hosting clause, name no country or region, and disclose no subprocessors. There is no trust or security page. A SOC badge image appears in the footer of every page, but it carries no caption, no report and no link, so it cannot be read as evidence of a completed audit. What can be observed concerns the marketing site rather than the product: the domain resolves to 198.202.211.1, an anycast address on Cloudflare's network geolocated to the United States, and the site itself is built on Webflow. Neither fact says anything about where company records or uploaded CRM files are stored. The jurisdiction is clearer than the hosting. Capix, Inc. is registered at 200 E 66th St, New York, and the Terms are governed by Delaware law with exclusive jurisdiction in the Delaware courts. Customers with data residency requirements will have to raise hosting location directly with the vendor, most likely through the Data Processing Agreement that section 4.4 makes mandatory.

Things to keep in mind
Risks and trade-offs to weigh before adopting Capix.
- The customer keeps rights to what it uploads, but section 4.3 lets Capix train models on aggregated, de-identified information derived from that content, and no opt-out is documented
- The complete absence of a privacy policy makes it hard to establish how personal data flowing through the platform is actually handled
- Templated legal pages left online at capix.ai/legal, written for another company entirely, can mislead anyone who reads them as Capix commitments
- A SOC badge in the footer, with no caption, report or trust page behind it, invites an assumption of certification that nothing on the site supports
- Annual billing with automatic renewal and only 15 days' notice for non-renewal can lock a team into a second year through simple inattention
- Contact details surfaced for decision-makers carry outreach duties under privacy and anti-spam rules that fall on the user, not on the tool
- Treating AI-aggregated company profiles as verified fact, without spot-checking them, risks carrying errors straight into a buyer list or a deal memo
Setup & Integrations
Technical difficulty
Technically there is nothing to set up. Capix is a web application with no installation, no deployment and no API key to configure, and queries are written in ordinary English rather than in a query syntax. Bringing in an existing CRM export or spreadsheet is a file upload. The real obstacle is commercial rather than technical: the product runs as a private beta with limited spots, so getting in means requesting an invitation, attending a demo and agreeing an Order. Teams who would rather not operate the tool at all can use the managed service instead.

Should you pick Capix?
Capix is a young product with a clear and defensible idea. Replacing filter grids with a request written in ordinary English, then having AI agents keep the underlying profiles fresh, answers a real complaint about private market databases, and the company is candid about what it competes with: a blog post from June 2025 names PitchBook and Capital IQ directly. The team behind it is small, five people according to Y Combinator's directory, and it went through the Summer 2022 batch.
What the site does not offer matters just as much. There is no published price, no free plan, no self-service sign-up and no API. Evaluating Capix means requesting an invitation to a private beta and sitting through a demo, after which commercial terms are negotiated in an individual Order that bills annually and renews automatically.
The documentation deserves particular attention. Capix maintains a single legal document, a Terms of Service last updated on 2 October 2025, and the footer links labelled both Terms of Use and Privacy Policy point to it. There is no privacy policy at all. The two legal pages served on the domain itself are an unadapted website template written for a different company, and nothing in them should be read as a Capix commitment. Hosting locations, subprocessors, retention periods and any opt-out from model training are all absent, and a SOC badge sits in the footer with no supporting text or report.
For a team whose sourcing work is currently manual, the demo is probably worth an hour. For a team with procurement or data protection requirements, the questions to raise before signing are already obvious: where the data lives, how long it is kept, who processes it, and what exactly the required DPA says.
