What BoostDraft does

BoostDraft is a Tokyo-headquartered software company founded in April 2021 by engineer Yohei Fujii and attorney Hiroshi Watanabe that builds an AI-assisted legal document editing platform distributed as a native plugin inside Microsoft Word. The product targets transactional lawyers and in-house legal teams, automating cross-reference error detection, defined-term management, formatting consistency, proofreading, and contract audit trails — effectively applying IDE-style developer tooling to legal document workflows. The platform is augmented by BoostDraft Compare, a multi-format document comparison add-on supporting Word, PDF, Excel, and PPT, including OCR for flat scans.

The company sells on a subscription SaaS basis with monthly billing and quote-based, non-publicly-disclosed pricing displayed at point of purchase. Its go-to-market is a hybrid of enterprise field sales (Global Chief Sales Officer, regional heads, Senior VP of Sales) and product-led adoption through the lightweight Word plugin, with distribution supplemented by content marketing (blog, eBooks), industry conferences (ILTACON, TechCrunch Disrupt, Collision), and an Actionstep integration partnership targeting midsize law firms. BoostDraft is bootstrapped, profitable since founding, and reports no external funding, serving 700+ legal teams and 10,000+ active users across Japan, South Korea, the United States, and the United Kingdom.
