Treblle helps developers with APIs

United States

Alphadoc is a developer experience platform founded in December 2020 by Daan Stolk and Job Rietbergen, designed to help companies market and sell access to their APIs through structured, template-driven documentation portals. The platform plugs into a company's source code and OpenAPI specification, providing frameworks that reduce the effort required to build and maintain a developer-facing documentation experience. As of May 2022, Alphadoc was operating in private beta with 10 active beta customers and approximately 40 additional companies identified as longer-term pipeline opportunities. The company had not yet begun charging customers. Stolk and Rietbergen closed a seed round of $250,000 from 15 angel investors in February 2022 at a $2 million pre-money valuation, selling approximately 11 percent of the company. The founding team of two was preparing to hire its first full-time developer and expand to a team of four to five people to complete the MVP. Prior to focusing full-time on Alphadoc, Stolk earned $30,000 over three months in 2021 through documentation consulting work, which provided personal runway while the company remained pre-revenue and pre-burn.
