CTO-as-a-Service
A fractional CTO for founders and product leaders: architecture strategy, technical due diligence, and engineering leadership. When you need to build, the same CTO brings a senior team on tap, so you can scale from advisory to full delivery as your needs change.

CTO-level ownership
A senior technical lead owns your architecture, roadmap, build-vs-buy decisions, and engineering standards, and is accountable for the outcome, not just for advice.
A senior team, on tap
Your fractional CTO isn't a lone individual. They're backed by a senior team of 100+ professionals across 13 countries. Need only leadership? Keep it lean. Need to build? The same CTO scales up the team, with no hand-off gap.
Technical due diligence
Codebase, architecture, security, and team assessment, for founders hardening an MVP or investors evaluating a target. A clear report with risks, effort, and a path forward.
Code & architecture audit
We review what you already have, including AI-generated and vibe-coded MVPs, find the structural risks, and lay out what it takes to make it production-grade and scalable.
How we engage
The engagement process
Discovery call
We map your product stage, technical constraints, team, and goals. No lengthy intake, we come prepared with the right questions.
Technical assessment
A short review of your codebase, architecture, and risks that de-risks scope and gives you a clear picture before you commit to anything.
Direction & ownership
We set the architecture direction, roadmap, and engineering standards, and define exactly what the team owns end-to-end.
Execution to production
Senior engineers ship under CTO-level direction, with a 90-day post-launch warranty on what we build.
A fractional CTO who can build
A solo part-time CTO can advise, but cannot build at scale. Ours is backed by a senior team you pull in when you need to execute, so you never have to choose between leadership and delivery. Use as much or as little as the stage requires.
We ship to production, not slideware
$10B+ in loans booked, $2.2B+ TVL secured, and 80+ products shipped. Our technical decisions are proven in production, not just on a roadmap.
Architecture-first and accountable
We design the system before writing code and own the outcome end-to-end. You get a partner accountable for delivery, not a consultant who leaves after the deck.
90-day post-launch warranty
Every engagement includes a 90-day warranty after launch. If something breaks in production, we fix it. No new contract, no billing conversation.

Get in touchYes, and more. You get a fractional CTO: a senior technical lead who owns your architecture, roadmap, and standards. The difference is they are backed by a senior team you can bring in when you need to build. Start with leadership alone, or scale to a full team that executes, without hiring a CTO and a separate dev shop.
Yes, and it is one of our most common engagements. We start with a technical due diligence and code audit to map the structural risks, then set the architecture and ship it to production-grade. It is the typical path for founders who moved fast with AI tools and hit scaling, security, or quality walls.
Yes. We run a technical due diligence and architecture review on what you already have, and give you a clear picture of the risks, the effort to fix them, and a path forward, useful before a fundraise, a scale-up, or just to know where you stand. Senior engineers run the review, not generalist analysts. (We run the same technical due diligence for investors evaluating a target.)
It starts with a discovery call and a short technical assessment. From there it ranges from ongoing CTO-level direction over a senior team, to a scoped build, to a one-off due diligence or audit. We size it to your stage and tell you honestly if we are not the right fit.
