BoostDraft is an AI-Assisted Document Editor that redefines document editing. It is a new document editor that employs automatic error correction, reference checking and auto-completion using both rule-based approach and NLP, like what coding editors (e.g., VSCode, Pycharm) do. We are a rapidly-growing, research- & engineer-oriented B2B startup, having achieved around 4,000 business customers within just one year after launch. We are exceptional in that we have been profitable from the beginning and have grown without needing any outside funding. While the legal headquarters is tentatively located in Tokyo, we are not location-limited and our team members are working from all over the world including the US, Taiwan, India, Malaysia and Japan. We are supported by a number of famed US accelerators, including MIT Sandbox, StartX, and MassChallenge.
