Holding company · Est. 2026

The holding company for what I build.

Grazier Ventures is where I build lean, AI-native products — designed to be genuinely useful and sustainable, not to raise a round. The first is Aqen.ai.

Founded by Duncan Grazier — CTO and advisor. Founder of TideHelm (advisory for founders, CTOs, and investors), former Chief AI Officer at BuildOps ($1B unicorn), CTO at Weedmaps (NASDAQ IPO), and VP Engineering at ShopKeep ($550M acquisition by Lightspeed).

01 — Thesis

Small, independent products under one roof.

The thesis

The thesis is simple: AI has collapsed what it costs — in time, capital, and headcount — to take an idea to a real business. So I build small, independent products under one roof, rather than chasing a single venture-scale swing.

Aqen.ai — first

Aqen.ai comes first: an AI cofounder that coordinates the non-product work of starting a company — legal, finance, marketing, ops. More may follow — each built lean, each built to stand on its own.

The writing — the public notebook
