Company Overview

About Aiwyn

Aiwyn is an enterprise software company founded in 2020 and headquartered in Austin, Texas, focused exclusively on automating the billing, collections, and payment workflows of accounting and professional services firms. The company's AI-powered platform sits at the intersection of fintech and professional services software — automating the time-consuming manual work of invoice preparation, accounts receivable follow-up, payment collection, and cash application that consumes significant non-billable hours in CPA firms, law firms, and consulting organizations.

Business Model & Competitive Advantage

The company raised $46M in total funding, including a $45M Series B in 2024, from investors including Growth Equity at Goldman Sachs Alternatives and Bessemer Venture Partners. Aiwyn's customer base includes large regional and national CPA firms — including many of the top 100 accounting firms in the US — that use the platform to reduce DSO (days sales outstanding), eliminate billing errors, improve client payment experiences, and free up partners from administrative collections work. The platform integrates with major accounting firm practice management systems including CCH Axcess, Thomson Reuters GEMS, and Sage Intacct.

Competitive Landscape 2025–2026

Aiwyn's core modules include Practice Autopilot (automated invoice generation and delivery), Collections Autopilot (AI-driven follow-up on outstanding invoices), and Payments (client payment portal and payment processing). The company competes in the practice management and billing automation segment alongside Ignition, BillQuick, and ArchiOffice, but differentiates through its purpose-built AI for accounting firm workflows and its deep integrations with the practice management systems that CPA firms already use. Its vertical focus on professional services — and accounting specifically — allows highly specific workflow automation that horizontal AR automation platforms cannot match.
