About Long Dinh
Long Dinh is the CFO of Ada, the AI customer service company, and is based in Toronto, Canada. The CFO Club describes him as having moved through Ada's finance organization from controller to senior leadership, after earlier investing work. He studied at Carleton University, according to his LinkedIn profile.
His LinkedIn headline says he is building TheGenAICFO.com, and he writes about AI changing company P&Ls. He has also posted about Ada's finance team using LLMs to automate workflows, and about what investors focused on in Series A fundraising.
The CFO Club lists him among SaaS angel investors, with a focus on SaaS finance, AI economics, fundraising and strategic finance. We did not find a public list of his angel investments beyond the round below, and no Crunchbase or PitchBook profile that clearly belongs to him. Check size and number of investments are not public.
In March 2026 he took part in the $3.6M seed round of Zalos, which builds AI computer agents that log into existing accounting and finance systems to do repetitive finance work. The round was led by 14 Peaks, with Cohen Circle, 20VC and several angels also participating. The angels included CFOs of FedEx and Tide, who are the kind of finance buyers Zalos sells to. He is listed in press coverage as CFO of Ada.
The only public evidence of his focus is the CFO Club listing (SaaS finance, AI economics, strategic finance) and the Zalos round, an AI product for finance teams. That suggests an interest in AI tools for finance and SaaS, and he brings an operator's view as a finance leader at an AI company. He has not publicly stated preferred stages, geographies or check sizes.
