A fractional CTO (sometimes called a fractional software architect or on-demand engineering lead) is a senior engineer who takes ownership of your technical direction without joining your payroll full-time. For most small and mid-sized businesses, the hard technical decisions — which stack to build on, how to architect for growth, whether an agency's proposal is sound, how to add AI capabilities responsibly — arrive long before the budget for a full-time CTO does.

Kuhn Consulting has provided exactly this kind of leadership since 2005: architecture and delivery for Fortune 500 enterprises including DaimlerChrysler, GM, Ford, and Aetna, and modern AI-era platforms like the multi-tenant Wildwood Platform and the API2MCP integration service. Every engagement is handled directly by Mark Kuhn, the firm's founder and principal engineer — the person you talk to is the person who ships the code.

§ 01 — What's included

What a fractional engagement covers.

Scoped to your stage — from a few hours of advisory a month to embedded technical leadership.

Technical Strategy

Technology roadmap, build-vs-buy decisions, stack selection, AI adoption strategy, and budget-realistic planning that matches engineering choices to business goals.

Architecture & Review

System architecture design, security and scalability reviews, code and infrastructure audits, and second opinions on agency or vendor proposals before you commit.

Hands-On Delivery

Unlike advisory-only CTOs, Kuhn Consulting builds: production AI integrations, SaaS backends, APIs, and cross-platform apps — shipped, deployed, and supported.

§ 02 — Who it's for

When a fractional CTO is the right call.

Founders without a technical co-founder who need someone to own architecture, evaluate developers, and translate product vision into a buildable plan.

Businesses adding AI capabilities that want LLM features built on solid foundations — provider selection, cost control, data privacy, and production reliability — rather than a demo that breaks under real users.

Teams outgrowing their first version whose software needs multi-tenancy, billing, security hardening, or performance work that the original build never anticipated.

Companies vetting outside vendors who want an independent engineer reviewing proposals, estimates, and delivered work before money moves.

§ 03 — How it works

A simple, low-risk way to start.

Engagements start with a conversation about where your product and team stand, followed by a scoped proposal — advisory hours, a defined project, or ongoing fractional leadership. Everything is remote, handled directly by the principal engineer, and structured so you can scale involvement up or down as your needs change. There are no subcontractors and no long-term lock-in.

§ Get in touch

Talk through what your product needs.

A short conversation is enough to tell whether fractional leadership fits.
