Senior, hands on fractional CTO.

Why a fractional CTO, and why now

You have a product, paying customers and a roadmap. What you do not have is a senior technology reference in the room when the hard calls get made. Architecture, vendor selection, the first engineering hires, what to build versus what to buy. These decisions compound. A wrong one slows you down for quarters.

Hiring a full time CTO is premature when the workload is real but not yet daily. You still need senior judgment for strategy, hiring and investor conversations. That is the exact gap a fractional CTO fills.

The cost of waiting is rarely a crash. It is drift: technical debt nobody flagged, a hire who was wrong for the stage, an integration that should never have been built in house. A senior reference catches these early.

We have seen this play out across our own clients. With Crown, the build versus buy line was the first call: a custom inventory layer would have cost months, so we kept the off the shelf core and built only the thin integration that was genuinely differentiating. With Kouleta, the same discipline applied to the early hiring plan, scoping the first two engineering roles before a single offer went out.

• Strategic decisions are being deferred because no one owns the tech vision.
• Investors or board members are asking technical questions you cannot answer with confidence.
• Your first engineering hires are too important to get wrong.
• You are evaluating build versus buy and need a neutral senior view.

How our fractional CTO engagement works

One of our senior CTOs becomes your dedicated technology reference. This is an extension of your team, not an outside advisor sending decks. No middlemen, no layers: you work directly with the person making the calls.

A typical engagement follows a clear sequence so value lands fast and stays accountable over time. With Mellender, the first three weeks were pure discovery, and the prioritized tech plan that followed reshaped the roadmap before the next sprint even started.

• Discovery: a deep read of your stack, team, roadmap and constraints in the first weeks.
• Tech strategy: a prioritized technology plan tied to your business goals and runway.
• Architecture: decisions on stack, scalability, security and the build versus buy line.
• Hiring: scoping roles, defining levels, interviewing candidates and onboarding your first engineers.
• Governance: board and investor updates, risk reviews, and clear reporting cadence.
• Ongoing cadence: two to four days a month, scaling up or down as your stage changes.

What a fractional CTO actually owns

A fractional CTO is a senior technology leader engaged part time to carry the responsibilities of a chief technology officer without the full time commitment. In a MAWT engagement, your fractional CTO owns four areas. Strategy: translating business goals into a technology plan your team can execute against runway and deadlines. Architecture: choosing the stack, setting scalability and security standards, and drawing the line between what you build and what you buy. Hiring: scoping engineering roles, defining seniority levels, running technical interviews and onboarding the people who will carry the product. Governance: speaking to your board and investors in language they trust, surfacing technical risk before it becomes a crisis, and keeping a reporting rhythm everyone can rely on. The result is C-level technical judgment, AI-native and senior, present on the days that matter, without the salary, equity and full time overhead of a permanent CTO.

Take a concrete build versus buy call. A growing company like rs detailing wants a booking flow plus a customer portal. Buying a standard scheduling tool covers eighty percent in days, while building the same from scratch burns a quarter and an engineer. The senior decision is to buy the commodity layer and build only the one workflow that is genuinely yours. That single framing, applied early, is often worth more than the entire monthly retainer.

• Technology strategy aligned to business goals and funding stage.
• Architecture and security decisions with clear ownership.
• Engineering hiring from role scoping to onboarding.
• Board and investor confidence backed by senior credibility.

Who it is for

This service fits Swiss SMBs and growing commercial companies with a product and traction, but no senior technology owner in the room. Founders who are strong on business and need a technical counterpart. Companies raising or growing who must show investors a credible tech function.

Legumes Express and Diagora are typical of the profile: real revenue, a working product and a roadmap moving faster than the in house tech bench could keep pace with. A fractional engagement gave each a senior owner for the decisions that mattered, without committing to a permanent C-level hire too early.

If your engineering load is already daily and full time, you may be ready for a permanent CTO instead. A fractional engagement is the right step when senior judgment is needed regularly, not constantly.

• Geneva-based and Suisse romande SMBs scaling a digital product.
• Founder-led teams strong on commercial, light on senior tech.
• Companies preparing a raise or a board that expects tech rigor.
