Aiwyn

Aiwyn is a practice-automation platform built for modern accounting and CPA firms, unifying payments, practice management, client experience, and tax into a single relationship-centered system. Aiwyn Payments automates invoicing, card and ACH collection, and reconciliation; Aiwyn Practice covers time, billing, project management and resource planning; Aiwyn Experience delivers a unified client portal for engagement letters and secure document exchange; and Aiwyn Tax adds AI-assisted tax preparation. The company serves 800+ firms and raised $113M from KKR and Bessemer Venture Partners. This profile was surfaced as a Bessemer portfolio company; Aiwyn publishes no public developer API, OpenAPI, or SDK surface at this time, so enrichment is limited to identity, its published llms.txt, and probed domain security.

Aiwyn is profiled on the APIs.io network. Tagged areas include Company, Ai Ml, Accounting, Fintech, and Payments.

Aiwyn’s developer surface includes support, engineering blog, release notes, and 6 more developer resources.
