Your engineering org, AI-First, in ninety days.
r90 is a practitioner firm for PE-backed and mid-market engineering organizations. Senior operators who’ve run the CTO seat embed with your team, modernize legacy systems, and rewire delivery around AI, so your team levels up by doing it, not by training for it. Momentum you can measure, not ninety slides.
What we believe
The gap isn’t tooling.
It’s the operating model.
We work with mid-market engineering organizations, especially PE-backed businesses where product modernization and AI adoption are part of the value creation plan.
AI does not speed up legacy engineering. It makes a different kind of engineering possible. We rebuild how the work flows, so the leverage shows up where it matters: phase by phase, with measurable ROI.
A method, a partner, and a playbook you own at the end.
01 · Why teams call us
Three problems. One method.
Different starting points, same operating logic. We start where your team is actually stuck, then turn that into faster, more predictable delivery.
You’ve adopted AI Tools. Delivery hasn’t changed.
Licenses everywhere, a mandate to "use AI", but you’re still shipping at the same pace with the same quality.
Technical debt is outrunning your roadmap.
Rebuilds keep getting shelved as too risky, while velocity, quality, and cost all slide the wrong way.
Your tools are working against your team.
Off-the-shelf tools that were once the safe default now drag; custom builds are suddenly the better economics.
02 · How we engage
Four phases.
End-to-end ownership.
Every engagement is custom. The arc is always the same.
Understand where you are today, where the friction lives, and which outcomes matter most.
A phased plan custom-fit to your current state and goals, not a cookie-cutter template.
Senior operators embed and ship the work, with your team building alongside them from day one.
The engagement is built to end. Your team helped build it, so the capability stays when we leave.
03 · Tools we bring
Purpose-built software, tuned to your workflow.
Every engagement runs on our own software. We bring it in, tune it to your workflow, and leave it with you at the end. A quick look at what we bring:
04 · Who shows up
Principals who’ve run the seat you’re in.
Every engagement is staffed by principals who’ve already lived the problem. No SDRs, no analyst pyramid.
Make the turn
Away from strategy decks
toward shipped software.
A thirty-minute briefing is enough to see whether r90 fits your situation. No deck. No pitch. Just an honest read on the route forward.
