About Hamilton AI
Hamilton AI is creating the operating system for business aviation. Unlike commercial aviation, business aviation lives in the dark ages, think emails, phone and spreadsheets that run most of the operations of operators from 2 aircraft to 1,000 aircraft.
Hamilton is here to change that. We offer a fully vertically integrated platform that runs business operations at our customers. Our AI agents are the first point of contact for quote requests and we run these quote requests from A to Z. Think quoting, flight scheduling and optimization, route planning, aircraft tracking, payment processing, and back-office invoicing and payroll.
Team
Hamilton AI is founded by Wouter Witvoet, who previously founded Secfi.com ($1.5bn AUM) and went on to take his second business public called DeFi Technologies, listed on the NASDAQ under DEFT with a market cap of $1.2bn. Other members are ex-Dropbox, Square, Airlabs, PagerDuty, Playbook, Walt Disney, Getaround, and NASA JPL.
Where we’re at
From January to March 2025, we took part in HF0 Residency-one of the world’s most exclusive programs for repeat founders, backed by Google, Andreessen Horowitz, and visionary investors like Naval Ravikant. In just 90 days, we made a year’s worth of progress-both in product development and real-world results.
Concretely:
We went from $150K to $1.5MM in ARR with both small and large enterprises.Raised $7.2M across two rounds most recently February 2025
Funded by leading VCs, including Bling Capital, TTV Capital, Cambrian VC, FJ Labs, Correlation VC, HF0, Mintaka Ventures, Weekend Fund
