The problem
Companies between 100 and 500 staff carry real technology risk — AI adoption, vendor bets, security exposure — without a senior technologist accountable for the decisions. The full‑time fix costs $300k+. Most don’t need it.
What I do
Fractional CTO,
on retainer
A deliberately small practice — a handful of retainer clients at 3–5 days a month each: technology strategy, vendor evaluation, AI adoption, security posture, hiring guidance.
Accountable for the decisions, not just the advice.
Short-term engagements
01
AI‑readiness audit
Where AI genuinely helps your business — and where it’s risk dressed as progress.
02
Vendor evaluation sprint
A rigorous, independent read on the claims before you sign.
03
Interim CTO cover
During a full‑time search — including evaluating your finalists.
04
Board advisory
A technologist in the room when the decision reaches the board.
Why me
Proof, not adjectives
- 7 consecutive years as fractional CTO for a financial services firm — regulated environment, full decision accountability, never replaced.
- Cybersecurity degree plus years of software engineering: I can evaluate vendor claims because I’ve built what they sell.

How I work
Accountable, not advisory
I own the technology decisions I make with you — not a slide deck of options.
I’ve built what they sell
Vendor claims get evaluated by someone who has written the software behind them.
Honest about fit
If you need a full‑time CTO, I’ll say so — and help you evaluate the candidates.
Common questions
Why not hire full‑time?
If you make 10+ significant technology decisions a quarter, you should — and I’ll help you evaluate candidates. Most companies your size don’t.
Where are you based?
I work remotely with clients across [TIMEZONES], with on‑site visits as agreed.
What does it cost?
Retainers from [RATE]/month depending on scope. A 20‑minute call tells us both whether it’s a fit.
