The spreadsheet grew up. Clay turned data enrichment, AI research and outbound into one workspace - and a $3.1 billion company.
CLAY, N.Y. - A go-to-market platform founded in 2017 by Kareem Amin and Nicolae Rusan, now used by more than 14,000 companies, from two-person startups to OpenAI and Anthropic. Photographed here: the company mark.
Most sales teams spend less than a third of their time actually selling. The rest disappears into research: hunting for the right contact, checking whether a company just raised money, confirming an email that won't bounce. Clay's founders looked at that gap and built a workspace to close it.
The interface is deliberately familiar - a spreadsheet. But each row can reach out to more than 130 data providers, ask an AI agent to read a company's website, score the account, and then draft a personalized message. The work that once took an analyst a morning happens in the time it takes to fill a column.
Clay does not own the underlying data. Instead it acts as an orchestration layer, pulling from a marketplace of providers and running them in sequence - a method the company calls a "waterfall" - until it finds the answer you asked for. Customers pay in credits, and only for results that come back.
That structure is the quiet reason Clay has grown from near-zero revenue to an estimated $30 million and a $3.1 billion valuation. It sells outcomes, not a database, and it improves every time a new provider joins the marketplace.
Ask Clay for a prospect's mobile number and it doesn't query one database - it cascades through many, stopping the moment it gets a hit. The result is 95%+ coverage on fields that single vendors routinely miss, and you're billed only for the successful lookup.
When the answer isn't in any database - "Are they SOC-2 compliant?", "Are they hiring SDRs?" - Clay's AI agent browses the open web and reads unstructured pages to find it. It has now run more than a billion times.
Trigger workflows on job changes, funding news or website visits, then push personalized sequences straight into Salesforce, HubSpot or email - no manual steps.
A spreadsheet-style canvas that centralizes data, enrichment, scoring and outbound in one place - with unlimited seats on every plan.
Sequential queries across 130-150+ providers for emails, phones and firmographics, charging only for successful results.
An autonomous research agent that reads public and gated sources to answer custom questions no single provider carries.
Multi-step AI workflows, now first-class, that automate research and GTM tasks end to end.
Built-in email sequencing plus two-way Salesforce and HubSpot sync, triggered by real-time signals.
A cohort program with 2,500+ alumni, plus Clay Clubs, teaching enrichment, ABM and prompt engineering.
"The GTM engineering era begins now."- Clay, Series C announcement, August 2025
Clay's customer roster is its sharpest endorsement. OpenAI, Anthropic, Perplexity and Cursor - the AI companies the rest of the market is chasing - use Clay themselves, alongside Canva, Intercom and Rippling. Users range from RevOps leaders at large enterprises to solo "Claygency" operators who resell Clay work as a service.
What sets it apart is architectural. Incumbents like ZoomInfo and Apollo sell access to a database they own. Clay sells the layer above the databases - so it isn't limited by any one vendor's coverage, and it gets better as the marketplace grows.
ZoomInfo and Apollo.io on data; Cognism and Lusha on compliance-first contacts; Unify and Instantly on AI outbound. Clay overlaps with all of them and sits above the category as an orchestration layer.
Clay is B2B SaaS with a usage twist. Annual plans bundle "data credits" (spent on enrichment, from about $0.05 each) and "actions" (spent on workflow logic). Every plan includes unlimited seats and tables - the meter runs on usage, not headcount.
100 data credits and 500 actions a month, unlimited seats, waterfalls, Claygent and the Sequencer - up to 200 rows per table.
Higher tiered credit and action volumes, phone enrichment, job-change signals, CRM auto-sync, HTTP API and webhooks.
100,000+ data credits, SSO, RBAC, data-warehouse sync and a dedicated growth strategist on an annual commitment.
100+ independent agencies build businesses delivering Clay to end customers - an expanding services layer around the core product.
Clay has raised more than $200M across its life. The 2025 Series C was led by CapitalG, Alphabet's independent growth fund, with Sequoia, Meritech, First Round, BoxGroup, Boldstart and new investor Sapphire Ventures joining.
Valuation trajectory: $1.25B (Jan 2025) → ~$1.5B secondary (May 2025) → $3.1B (Aug 2025). Bar widths are illustrative, scaled to round size.
Kareem Amin, born in Egypt and trained in electrical engineering at McGill, started Clay with fellow McGill graduate Nicolae Rusan in 2017. Varun Anand joined in 2021 to run operations. Their thesis - that go-to-market would become an engineering discipline - took the market years to accept. By 2026 there are more than 280 open "GTM Engineer" roles at companies like Cursor, Notion and Webflow.
Kareem Amin and Nicolae Rusan start Clay in Brooklyn to make growth ideas executable through data and automation.
Anand comes on as co-founder as Clay raises early venture money from First Round, Boldstart and BoxGroup.
The AI research agent extends enrichment beyond structured databases to open-web research.
A $46M round led by Sequoia and Meritech lands as revenue grows roughly sixfold.
A $100M round led by CapitalG values Clay at $3.1B; Claygent passes one billion runs.
Clay expands its cohort course and community as "GTM Engineer" roles proliferate across the industry.
The AI agent is called Claygent - a pun that has now handled over a billion research tasks.
Independent agencies called Claygencies exist solely to run Clay for other companies.
Clay effectively coined a job title: the GTM Engineer, now hired across the tech industry.
Its data strategy is a waterfall - cascading through provider after provider until it finds the answer.
Its marquee customers - OpenAI, Anthropic, Perplexity - are the very AI labs the market is trying to sell to.
Co-founders Kareem Amin and Nicolae Rusan both studied at McGill University in Montreal.
Clay is a go-to-market platform that enriches customer data from 130+ providers, researches accounts with an AI agent (Claygent), and automates personalized outbound - all inside a spreadsheet-style workspace.
Clay was founded in 2017 by Kareem Amin (CEO) and Nicolae Rusan, with Varun Anand joining as a co-founder in 2021.
Clay has raised over $200M in total, most recently a $100M Series C in August 2025 led by CapitalG at a $3.1 billion valuation.
It's Clay's method of querying data providers in sequence until a match is found for a field like an email or phone number, maximizing coverage while charging only for successful results.
More than 14,000 companies, from startups and specialist agencies to enterprises, including OpenAI, Anthropic, Canva and Intercom. Typical users are sales, marketing, RevOps and GTM engineers.
