Fractional CTO & Technical Advisory
Senior technical leadership for funded startups and growing mid-market companies that need someone who has actually shipped what they’re trying to build.
Book a 30-Minute Fit ConversationScaleLogic’s fractional CTO engagements are led by Rick Mazurowski — thirty years building and operating production systems, including biometric ML at regulatory scale, multi-tenant SaaS, payment infrastructure under continuous PCI-DSS compliance, and multi-jurisdiction compliance architecture. The work behind the case studies on this site.
When engagements need deeper execution support, we draw on a network of vetted senior engineers built over those thirty years. The shape of the engagement adjusts to the work; the technical judgment behind it does not.
Four areas where senior technical judgment compounds. The mix is calibrated to your stage during the first conversation.
Guide the architectural decisions that determine whether a product scales or stalls. Input from a partner who has designed multi-tenant systems serving hundreds of concurrent clients — and lived with the consequences for two decades.
Level up an existing engineering team through code review, design review, and direct mentorship. When hiring, define the roles that actually move your roadmap and screen for senior signal beyond the résumé.
Cut through vendor pitches with an independent technical perspective. We evaluate platforms, infrastructure, and AI providers based on what survives production — not what looks good in a demo.
Align technology investment with where the business is actually going. Build versus buy versus defer, sequenced against funding milestones and the cost of getting the order wrong.
No discovery-phase theater. By the end of month one, the engagement has produced movement — not a slide deck.
Architecture review and three to five working conversations with your team and key stakeholders. We map the actual stack, the actual constraints, and the actual decisions in flight.
Written assessment delivered. Prioritized risks, the two or three decisions that need to be made first, and what we’d do differently in your position.
Agreed engagement cadence. Weekly architecture review, monthly strategy session, on-call for the decisions that can’t wait — calibrated to what your stage actually needs.
First decisions executed alongside your team. By month one, the engagement has produced concrete movement, not a slide deck.
A short sample of architectural calls made on real engagements. Each links to the full case study.
Architected a biometric identity platform with multi-algorithm ML consensus, browser-based inference across WebGL/WASM/WebGPU, and regulatory compliance enforced across 25+ jurisdictions. The kind of CTO-level decisions that determine whether a product can ship into regulated markets at all.
Read the case studyDesigned a multi-tenant SaaS platform with a provider-agnostic LLM abstraction across five model providers and bring-your-own-key per tenant. Architected for cost optimization and vendor independence from day one — the decision most teams only make after they’re locked in.
Read the case studyArchitected a 14-storefront e-commerce platform on a single codebase with isolated per-tenant security boundaries, seven payment gateways, and continuous PCI-DSS compliance maintained across two decades of production operation. Scale and compliance designed in, not retrofitted.
Read the case studyYou’re building something real with limited time and a small engineering team. The decisions in front of you — architecture, hiring, AI stack, compliance posture — will compound for years. We help you make them with someone who has shipped the answer before, not someone reading the same blog posts you are.
You have a working business on systems that are starting to constrain it. Replatforming all at once is too risky; doing nothing is more expensive every quarter. We design phased migration paths that protect revenue while moving the stack forward — the same approach we have applied for clients carrying twenty years of production history.
Technical Due Diligence
Series A and B investors send technical due diligence teams that will examine architecture, security posture, compliance, code quality, and key-person risk. We prepare companies for that review the way we’d prepare our own — surfacing the real risks first, fixing what’s fixable, and writing the narrative for what isn’t. Engagements typically begin three to six months before the round opens.

We’ll give you an honest read on whether fractional CTO is the right shape for your stage, what level of engagement makes sense, and whether ScaleLogic is the right partner. If we’re not, we’ll point you toward someone who is.
