Shipped in weeks,
not months.
Senior builders and agentic AI, building production software for the most regulated environments.
SupTech first
Built for the people who supervise the system.
Line4 builds SupTech: the software financial authorities use to supervise their markets. It is the hardest software to get right, which is why we start there. Everything else we build inherits that standard.

Proven in production
Real outcomes where the stakes are highest
Four production systems shipped in six months. AML supervision intelligence, enforcement case management, regulatory submissions, and legacy vendor replacement. Competitors quoted eighteen months.
What you get
SupTech software. Senior engineers around it.
The Line4 suite runs the core of supervision: collection, reporting, casework, regulatory knowledge. A Line4 Pod, senior builders paired with agentic AI, shapes it to your framework and builds the bespoke edges no product covers.
Meet the builders
Senior builders backed by agentic AI that never clocks off. A revolving bench, one accountable team.
Why it ships in weeks, not months
The product is already built. The team shaping it is small, senior, and never hands work off.
Agentic AI, around the clock
Your Pod keeps building while you sleep. The same delivery approach that ships SupTech unlocks value anywhere in a regulated business.
