AI coworker for accountants — tax, audit, and accounting automation
HQ: London, UK | Founded: 2024 | Employees: 4 | Stage: Pre-Seed | Website: https://combinely.ai
Combinely builds an AI coworker for accountants that automates tax, audit, and accounting workflows end-to-end. The AI works like a junior team member, handling workflows across multiple systems without human intervention. For tax teams, it automates tax preparation, research, and compliance. For audit, it handles audit procedures and documentation. For accounting, it automates reconciliations and workflows. Built by an ex-Deloitte/Google DeepMind team. Founded in 2024 by Tom Invernizzi (CEO) and Arthur Granacher (CTO). Invernizzi previously worked at Deloitte and PWP (Perella Weinberg Partners). Granacher spent 4 years at Google DeepMind automating doctor workflows, and earlier developed at Shazam. YC X25 (Spring 2025) batch. Raised $500K+ from Y Combinator and Eight Capital Management. Over 1,500 accountants have joined the platform. HQ in London, UK.
Combinely's founding team combines accounting domain expertise (Tom at Deloitte) with world-class AI engineering (Arthur at Google DeepMind, Shazam) — a strong combination for building AI for accountants. The 'AI coworker' positioning (vs 'AI that replaces accountants') is smart for adoption. The 1,500+ accountants who have joined suggests early traction. Key challenge: the accounting AI space is getting very crowded (Truewind, TaxGPT, Bluebook, Boton, etc.), and convincing accounting firms to trust AI with client workflows is a gradual process.
