Customers are building various applications on Browserbase, including web scraping, testing, AI agents, B2B software, and professional services. The company has experienced rapid growth, with thousands of hours of browser sessions per week. To handle the scale, Browserbase had to make architectural changes, such as moving from Postgres to ClickHouse for better performance. They also had to address challenges like connection management, resource allocation, and debugging customer issues. The founder believes they have achieved product-market fit based on strong customer retention and repeatable growth strategies. Browserbase is a technical product, so the number one priority for hiring is that candidates are technical and understand what Browserbase does.
