Hi—I'm Stephan.
I'm a fractional CTO and writer. I help CEOs make their tech stack something investors trust—understandable, defensible, and aligned with how the business actually runs.
Background
I'm a seasoned CTO. I've raised money, built companies, and shut them down. The pattern that kept showing up was the same: teams needed a clear story about their technology—not more tools, but judgment that holds up under questions from investors, acquirers, and their own boards.
Today I work with founders who want that clarity. Boston-based; co-founded a company in the Techstars Boston cohort (2018). I've led engineering from two people to forty, lived through SOC2, cloud migrations, and more than a few pivots—so when I write or advise, it's grounded in what it feels like when the stack has to match the business plan.
When I'm not in client work, I'm building in public, scoring tools for the playbook, and testing ideas so the recommendations I share don't age into generic "best practices."
I write and work around a few themes
Pick what matches where you are—each path ties back to the same goal: a tech story you can defend when it matters.
- 01
What your stack signals
How delivery, vendors, and debt read to investors, buyers, and boards—and how to tighten the narrative before it costs you leverage in a round or diligence.
Read insights - 02
Low-code with discipline
Honest tool picks from the playbook: when visual tools earn their place, when they become silent risk, and how to defend the choices in language a non-engineer CEO can repeat.
Open the playbook - 03
Build in public
Shipping Fractional.tools and documenting what breaks, what ships, and what I would do differently—so advice stays tied to real constraints, not theory.
Follow the build - 04
When the stakes jump
Hands-on work with founders and CTOs in transition—stack reviews, deeper engagements, and clarity when guessing wrong is expensive.
