Who we build for
Operators who
Operators who
measure outcomes,
not activity.
We work with a small, curated list of firms each year — teams where the cost of a bad build is high and the reward for the right one changes the business.
02
Professional Services
Bespoke matter-management, deal-flow and client-intelligence platforms for law, finance, and consulting practices.
03
Healthcare & Regulated
HIPAA-compliant CRM and AI workflows for clinical, life-sciences and payer organizations where audit trails matter.
04
Funded Startups
Series-A+ teams that need a senior engineering bench without the overhead — shipping production software in weeks, not quarters.
The thesis
Most agencies sell features. We ship systems. The difference shows up three years in — when your CRM is still the backbone of the business, your AI actually reduces cost, and the code you paid for isn't a rewrite waiting to happen.
