Aiwyn

Aiwyn builds software for accounting firms. Founded in 2020, the company delivers what it describes as the first complete platform built specifically for modern accounting practices, consolidating fragmented tools and manual processes into a single system spanning payments, practice management, client experience and tax. The Aiwyn Platform is designed to manage a firm's business end to end, replacing a patchwork of disconnected products with one intelligent ecosystem.

The product line comprises four modules alongside the underlying platform: Payments, an integrated payments solution for accounting firms; Practice Management, tools intended to streamline firm operations and reduce complexity; Client Experience, solutions for faster and more consistent service delivery; and Tax, tax functionality integrated into the end-to-end platform. The technical work spans practice management software, payments technology, tax software, client experience platforms, systems integration and platform consolidation, and AI-driven automation.

More than 800 accounting firms use Aiwyn. The company has expanded through multiple strategic acquisitions and is backed by investors including KKR and Bessemer Venture Partners. It serves accounting, professional services, and tax and advisory firms.
