Quanta sells an AI-powered accounting platform to software companies, automating bookkeeping in real time rather than in monthly batches. The platform ingests data from a company's existing fintech tools such as Brex, Mercury and Stripe to automatically produce books and live financial reports, replacing slow legacy accounting software. Founded in 2023 in San Francisco by Helen Hastings, a former Affirm software engineer, and Theodora Chu, Quanta raised a $4.7M seed led by Accel with participation from BaseCase, Comma Capital, Designer Fund, Operator Collective and Elad Gil.
