PostHog, a platform that helps developers build and optimize products, has secured $70 million in a Series D funding round, bringing its valuation to $920 million. The round was led by Stripe. 

Additionally, PostHog completed a Series C round aimed at providing liquidity to early employees by letting them sell a portion of their shares. This liquidity program was expanded in the Series D round to allow any employee to sell up to 20 percent of their vested shares.

Over the past five years, PostHog has expanded its product suite from initial product analytics capabilities to a comprehensive range of tools, including web analytics, session replay, experiments, feature flags and surveys. The company has further enhanced its offerings with a data warehouse, error tracking and LLM observability. PostHog’s vision is to create an AI-powered “customer infrastructure” that consolidates every customer interaction into a single, comprehensive record. 

The new funding will be used to develop new products for support, sales and marketing, as well as to meet the increasing demand for the company’s existing tools. PostHog aims to automate the entire toolchain that businesses use to grow, creating a seamless and efficient customer data platform.
