Affiniti: Redefining Financial Management for Small Businesses with AI

A startup has set its sights on revolutionizing the financial landscape for the 33 million small businesses in the U.S. With a significant new financing round, Affiniti aims to enhance the role of AI agents as essential tools for small and medium-sized enterprises (SMEs).

New Funding Boost

Affiniti recently secured $17 million in Series A funding, led by Signalfire. Notable participants in the financing round include Contraring Thinking Capital, Continue, Indicator Ventures, Lightshed Ventures, Riverpark Ventures, as well as influential figures such as Yahya Mokhtarzada, founder of Rocket Money, and Austin Rief, co-founder of Morning Brew, along with Chelsea football club player Trevoh Chalobah.

Empowering SMEs

Founded in 2021 in New York, Affiniti is dedicated to supporting small and medium-sized enterprises, which constitute 99.9% of U.S. businesses and employ nearly half of the American workforce. According to the U.S. Chamber of Commerce, these businesses also account for 43.5% of the country’s GDP. Despite their significance, co-founders Aaron Bai and Sahil Phadnis believe that many SMEs lack essential financial tools to thrive, including platforms for expense tracking and financial analysis.

Innovative Solutions Launched

Affiniti debuted its first products in November 2024, introducing a spending management platform and a small business credit card, backed by $11 million in initial funding. As the duo onboarded clients, they found that for many SMEs, Affiniti was their first experience with fintech, highlighting a gap in the market for accessible financial solutions.

The Rise of AI in Finance

As AI technology gained traction in Silicon Valley, it presented Affiniti with a unique opportunity to develop a “CFO AI” that could oversee various financial tasks for businesses, including banking, invoicing, and sales management. Phadnis emphasized that their AI is not only versatile across industries—such as healthcare, finance, and automotive—but also capable of delivering tailored financial advice based on specific sector needs.

Navigating Regulatory Challenges

AI agents have historically been slow to penetrate the highly regulated finance industry, especially compared to sectors like sales and advertising. However, startups like Hebbia and Auquan are paving the way, with Hebbia raising $130 million for AI-powered banking solutions. These advancements demonstrate a growing acceptance of AI in financial research and management.

Future Directions and Vision

Looking ahead, Affiniti aims to focus on customer acquisition and leveraging data. Phadnis asserts, “The true power of AI agents lies in the data on which they are trained.” By establishing itself as the go-to platform for managing SME financial activities, Affiniti is poised to develop a highly precise CFO AI tailored to different industry verticals.
