Fern has revealed a new Series A funding of $9M, bringing its total capital raised to $13M. Leading the investment is Bessemer Venture Partners, with participation from Y Combinator. The influx of funds underscores growing demand for automated SDKs and modern documentation solutions, enabling organizations to streamline their developer experiences.
Over 150 companies, including Square, Webflow, ElevenLabs, LaunchDarkly, and Intercom, rely on Fern to ease the burden of building and maintaining API integrations.
The platform helps teams create consistent, brand-aligned documentation and generates SDKs for multiple languages in one go.
The accelerating shift toward AI-driven products has made it essential for developers—and now AI agents—to integrate with APIs quickly. Fern’s approach reduces heavy engineering tasks and ensures consistent, high-quality code is always at hand. By aiming to simplify integration efforts, the company positions itself as a partner for both emerging startups and established tech giants seeking to scale.
“The explosion of AI-driven developer tools has created an urgent need for faster, frictionless integration. By eliminating friction from the developer experience and managing the gritty engineering work that is building and maintaining SDKs and docs, Fern has established itself as a trusted enterprise partner.”

Fern’s latest capital infusion will help broaden its existing language support and scale its product development. The team aims to meet the rising demand for automated solutions by refining how clients maintain in-sync SDKs and docs. Plans also include expanding into new markets where AI agents are playing a bigger role in code creation, testing, and continuous integration.
Future releases will focus on bridging the gap between human developers and AI-driven systems. With an emphasis on consistent, always-updated documentation and multi-language SDK generation, Fern seeks to pave the way for seamless adoption of new standards and protocols.
Founded in 2023, Fern emerged from the realization that many organizations struggle to maintain top-tier developer experiences. The company created a single pipeline that syncs SDK generation with documentation updates, ensuring reliable, up-to-date references. What used to require multiple teams and constant manual maintenance is now handled through Fern’s platform.
By catering to companies large and small, Fern empowers teams to deliver enterprise-grade developer experiences without hiring specialized staff. High-profile brands mention saved time, reduced overhead, and increased developer trust as some of the platform’s immediate benefits.
This Series A round cements Fern’s reputation as a go-to solution for simplifying integrations. Bessemer Venture Partners led the funding, while Y Combinator added its vote of confidence. Together, they bring Fern’s total fundraising to $13M, fueling the company’s vision of automating both human and AI-enabled API interactions.
