For CEOs and engineering leaders navigating the shift
I've been building with agentic engineering before it even had a name. We embed with PE portfolios and growth-stage CTOs to close the AI valuation gap — at fund speed, not consultant speed.

The agentic engineering shift
Your competitors aren't hiring more engineers. They're building more with fewer.

months behind.
That's how far behind the average vertical SaaS portfolio company is on AI adoption — and competitors compound the advantage every quarter.
Closing that gap in Year 1 post-acquisition is what separates the funds compounding multiples from the funds writing it off. Heavy Chain exists to close that gap — at fund speed, before, during, and after the check.
Services Snapshot
Every engagement starts with where you are in the agentic engineering shift — and ends with your team operating on the other side.
The core engagement
Embedded technical leadership on retainer. We own the hard calls on architecture, people, and delivery cadence — so your team ships instead of spins. Built for PE-backed operators, growth-stage companies, and founding teams.
Currently embedded across a portfolio of B2B SaaS companies — fund-level diligence and portco-level execution. Two altitudes of leverage, one operating rhythm.
Your team knows something is broken. We find the root cause in days, fix the delivery engine in 90, and leave managers with the tools to keep it running. 300% output increase, 40% cost reduction — in a single engagement.
