TL;DR: Clay has raised $115M in Series D funding at a $7.1B valuation, following 4x revenue growth in 2025. More than 17k customers, including 80% of the Forbes AI50 and companies like Anthropic, Google, OpenAI, Stripe, ElevenLabs, Visa, Siemens, and UPS, use Clay as their infrastructure for growth.
AI is unleashing the biggest wave of company creation in history. Clay's goal is to be the engine those companies use to grow to their full potential.
Clay predicts the next best action for your business and then helps you take it. We started by aggregating the best data for B2B companies. Then, we built the infrastructure to run any personalized campaign on top of it, including emails, ads, landing pages, and workflows. Now, we're building agents that can help grow your company for you.
GTM engineers run growth agents the same way software engineers run coding agents. These agents can help find your ideal customers, monitor intent signals for your product, launch new features to the right customers, and more. As they run, Clay comes to understand everything about your business, your market, and your customers. It learns from the outcomes, and improves the more you use it.
We're building a self-learning revenue engine. The better a company gets at learning, the faster it grows. To back this vision, Wellington led our $115M Series D at a $7.1B valuation, with participation from Sequoia, Stepstone, a16z perennial, Meritech, DST, CapitalG, BoxGroup, Boldstart, Bloomberg Beta, and Evolution.
The GTM system that learns from every run
Clay unifies your full company context: CRM data, product usage, campaign engagement, calls, emails, and more. It also layers on signals from the outside world, like funding events, hiring activity, and job changes. From all of it, Clay builds a live understanding of your total addressable market — and shares it across your entire company.
With that context, simply describe a business goal in plain language, and Clay will build it into a workflow your team can inspect and adjust. Ask Clay to book meetings with fintech marketing leaders, for example, and it will find the right people, research their businesses, build a tailored presentation for each prospect, and set up outreach.
Later, a prospect in that campaign might mention when their contract ends and ask for a pricing clarification. Clay will remember the timing, notice that other prospects had the same question, and update your materials to answer it. You have full control, whether you create deterministic workflows yourself or let AI agents build them.
We have exciting product features to share, so stay tuned for our upcoming launches at Sculpt, our second annual conference.
Announcing $1m to grow the next wave of GTM Engineers
We believe that the next wave of companies will be built by teams that think about growth in a systematic way. We call those people GTM engineers. Thousands of them already build revenue systems at some of the fastest-growing companies in the world, and their role is expanding.
People come to GTM engineering from all kinds of backgrounds: RevOps, growth marketing, software engineering, design, and more. This is just the beginning, and we want to make it accessible to more people.
Our new $1 million scholarship fund will train the next generation of GTM engineers. If we do it right, we'll be powering the next wave of the world's economic growth. Come build the future with us: we're hiring.
