Clay co-founder and CEO Kareem Amin said: “AI is unleashing the biggest wave of company creation in history, and Clay’s goal is to be the engine those companies use to grow to their full potential. We started by aggregating the best data for B2B companies.
“Then we built the infrastructure to run any personalised campaign on top of it. Now we’re building agents that can help grow your company for you. We’re building a self-learning revenue engine. The better a company gets at learning, the faster it grows.”
In addition to the funding, Clay has set up a $1m scholarship scheme aimed at training future “go-to-market” engineers and professionals who focus on building business revenue systems.
Amin said: “We believe the next wave of companies will be built by teams that think about growth in a systematic way. We want to make this career accessible to more people. If we do it right, we’ll be powering the next wave of the world’s economic growth.”
In August 2025, Clay raised $100m in a Series C funding round, bringing its post-money valuation to $3.1bn.
