Axion Ventures
Every venture starts with
something broken.
One founder · One methodology · One venture at a time
Axion Ventures is a solo-founder venture studio powered by SPARC, a proprietary AI development methodology. Each venture targets a market where the existing solutions are lazy, extractive, or just bad.
The Ventures
On hold
Nexus
Your bank is built for One. Your life is built for Two.
A financial wellness platform for couples that replaces guilt-driven budgeting with collaborative money management. Proof of concept complete, on hold pending funding.
AI role: Data processing and pattern analysis.
Methodology
SPARC
SPARC is a TDD-first AI development methodology using a multi-agent architecture. It turns a solo founder into a small team. PoliCRM was built in 48 hours with it. Zetto's entire spec suite was designed and documented in days, not months. The methodology is the competitive advantage.

I'm Ethan.
I've spent 13 years building systems — from retail operations to AI pipelines to political campaign infrastructure. I created SPARC because I wanted to build products at the speed and quality of a full team, without needing one. Axion is the vehicle. The ventures are the point.
