Quanta

Quanta is a San Francisco-based accounting services company built for SaaS businesses, pairing expert human accountants with proprietary software that "shows its work." The platform delivers continuous accounting and reconciliation, explainable financial reporting through its agentic reporting layer (Prism), SaaS revenue and accounts-receivable insights, and real-time visibility into cash, burn, and runway alongside department-level spend tracking. Quanta is a managed-services and software product for finance teams rather than a developer-facing API provider; it publishes no public API, developer portal, SDKs, or OpenAPI at this time. It was surfaced as a portfolio company of Accel and Homebrew and added to the API Evangelist network.

Quanta is profiled on the APIs.io network. Tagged areas include Company, Cloud Saas, Accounting, Fintech, and Bookkeeping.

Quanta’s developer surface includes engineering blog and 6 more developer resources.
