In April, Modus AI, a New York-based holding company, announced a combined Seed and Series A round of $85 million, led by Lightspeed Venture Partners [BusinessWire, April 2026]. The company pursues a dual-track strategy: building proprietary AI audit software while acquiring majority stakes in established accounting firms [Axios, April 2026].
The Platform-and-Partner Wedge
Modus positions itself as a scaled platform for growing audit-first accounting firms [BusinessWire, April 2026]. The playbook has two clear motions:
- Proprietary AI tooling: The company develops software to automate manual audit procedures and enhance risk assessment [BusinessWire, April 2026].
- Strategic capital deployment: Modus acquires majority stakes in advisory entities affiliated with these firms, providing technology and growth capital [Axios, April 2026].
Early Traction and a Top 200 Anchor
Since its launch in June 2025, Modus has invested in an unnamed firm ranked in the top 200 of Inside Public Accounting's list, a platform with over $30 million in annual revenue [CPA Practice Advisor, April 2026]. Modus claims that deploying its AI platform at this firm is expected to more than double the firm's organic growth rate in 2026 [BusinessWire, April 2026].

The funding round, led by Lightspeed with participation from Comma Capital and Garry Tan, supports the company's technology development and further investments in partner firms [BusinessWire, April 2026].
