About Flare

Flare is building the first AI accounting firm, serving startups and high-growth companies.

Today, we operate as an AI-powered accounting firm serving US & UK businesses employing human accountants across the US and India. In practice, with ex Y Combinator founders, we behave much more like a technology startup than a traditional accounting firm. Engineering is at our core as we develop our own software and AI agents that can be used by our accounting and sales teams with the ultimate goal of achieving software level margins with all the benefits of a services business (notably low churn + high customer lifetime value).

Founded in 2022 by ex-KPMG leadership and Y Combinator alumni, Flare has grown to over $2.5M ARR, with just 30 humans. Our clients include YC, Sequoia, a16z and OpenAI backed startups (e.g. Solve Intelligence, Heron Data & Sully.ai) as well as public companies such as DeFi Technologies (NASDAQ: DEFT).

There are 2 important waves that we’re surfing:

1) AI Agents will enable services to scale like software.

Accounting firms have never been able to scale revenue without increasing headcount. As a result the profit margins are traditionally compressed at ~20% given the limited operating leverage available. No firm can scale past their headcount ceiling resulting in an incredibly fragmented market with most practices doing less than a few million in revenue per year. This is despite accounting services having one of the largest TAMs on earth and one of the best retention business models. The bottleneck isn’t demand, it’s operations. Solving this problem will unlock infinite scale.

Our vision is to create the first infinitely scalable accounting firm, run by software.

2) AI is creating more companies.

Suddenly founders need less capital, smaller teams and less time to reach product-market fit thanks to AI. This means it’s now even easier to start a company so in the future we will see dramatically more companies created that shouldn’t worry about building an internal finance function from day 1; and it’s already showing up in incorporation statistics:

Bar chart of Stripe Atlas startup incorporations by quarter from 2021 through Q1 2026, with a sharp spike above 6,000 in Q1 2026.

To sum it up, we’re in a market dominated by dinosaurs that don’t realise there’s a meteor on the horizon. As we build more agents to replace human tasks, we will increasingly scale like a software company, launching new services and geographies that we can apply our software margins to. Our ambition is to build a $100m business within the next 3 years given the scale of our growth, profitability and the rapidly growing opportunity in startups; but beyond that, the next big 4 firm.

Flare is backed by an incredible group of select investors including Eric Feng (former GP @ Kleiner Perkins and co-founder of Hulu) and Chaz Englender (YC founder & Cofounder/CEO @ Model ML, YC W24).
