Major milestones include rapid acceleration from initial seed funding in 2020 to a substantial Series D round in 2025. PostHog’s funding approach has strategically combined capital for product innovation, employee liquidity, and scaling operations. Key investors such as Stripe, Y Combinator, Google Ventures, and Formus Capital have played pivotal roles in fueling the company's growth and product expansion initiatives.
This late-stage round was led by Stripe, with strong participation from Y Combinator, Google Ventures, and Formus Capital. The purpose of the Series D round is to drive product expansion, especially in the realm of AI-powered customer infrastructure, and to rapidly scale business operations to meet surging demand. The round set the company's valuation at $920M.
The Series C round focused on shareholder liquidity, allowing early employees to sell shares and increasing founder control. This was a modest capital raise designed to reward long-term team members and optimize the company's cap table ahead of large-scale expansion.
This extension of the Series B was intended to accelerate growth, support ongoing product innovation, and fuel market expansion.
