PostHog Raises $70M in Series D Led by Stripe After a Simple Tweet
PostHog, a developer-focused platform for customer data and product analytics, has raised $70 million in a Series D funding round. The round was led by payments giant Stripe, pushing PostHog’s valuation to $920 million.
Other investors included Y Combinator, GV, and Formus Capital. This latest raise brings PostHog’s total funding to $107 million since its launch in 2020.
From Analytics Tool to All-in-One Developer Platform
PostHog started as a simple product analytics tool. Today, it’s evolved into a complete platform designed to give companies full control over customer data. Its open-source model lets developers access and manage data without relying on third-party integrations.
Co-founders James Hawkins and Tim Glaser launched PostHog during Y Combinator’s Winter 2020 batch. For the first 18 months, they focused solely on building open-source tools before shifting toward revenue.
Now, the platform offers 14 integrated tools that help product and engineering teams better understand and support their users. Hawkins refers to this as providing “customer infrastructure” — meaning all customer-related tools are built into one unified system.
A Tweet That Sparked a Deal
What makes this funding round unique isn’t just the amount — it’s how it started.
In November 2023, Stripe CEO Patrick Collison unexpectedly tweeted praise about PostHog’s website. That tweet opened the door for a meeting between the teams. According to Hawkins, the conversation quickly turned into something more.
Stripe later confirmed its investment, although it declined to share further details.
