StackOne, founded a year ago by ex-Google and Oracle executives, has raised £2.8 million in seed funding.
CEO Romain Sestier and CTO Guillaume Lebedel founded StackOne to empower SaaS companies to connect their products with their customers’ existing ecosystem via standardised APIs for entire categories of software.
The funding was led by Episode 1 with participation from Playfair Capital, Portfolio Ventures, Charlie Songhurst, Sequoia’s Scout fund and others.
Angel investors include the co-founder of Github, as well as executives at Google, Microsoft, Salesloft, Tessian, Hackajob and more.
StackOne will use the funding to invest in AI to grow its unified API offering for the enterprise software-as-a-service sector and further expand its presence in the US, EU, and Australian markets.
It said it has seen exceptionally fast ARR growth since its launch, more than doubling its revenue in the last few weeks.
“The explosion of SaaS tools has created an integrations nightmare for companies,” said Hector Mason, general partner at Episode 1.
“StackOne, one of the first investments from our new £76m third fund at Episode 1, has quickly demonstrated its unified API to be superior to competition across important dimensions. They’re making great strides towards a future where companies don’t have to think twice about building and managing hundreds of integrations.
“I know that Romain and Guillaume won’t stop until this work is done, and many thousands of companies will benefit from their extraordinary ability and ambition.”
Sestier added: “The response to StackOne and our integration platform has been nothing short of amazing.
“When we set out to build StackOne a year ago after I left Google, our vision was to build an enterprise-grade integration platform for modern SaaS companies. Today, we are thrilled to have the backing of Episode 1 and Playfair to support StackOne’s vision.”
