Your startup needs a CTO. It does not need the full price tag.

Part-time technical leadership for startups that want to make the right architecture, team and product decisions from day one.

30 minutes free, no commitment

Stack & architecture

I define the right tech stack for your current stage. Not the trendiest one — the one that lets you iterate fast and scale when you need to.

Team & processes

I hire and manage your technical team. I set up development processes, code review and deployment workflows that work from day one.

Product roadmap

I translate business vision into a realistic technical roadmap. I prioritise what matters and cut what can wait.

How I work

01

Diagnosis

I assess your current situation: team, stack, product, roadmap. I identify what works, what does not, and what is urgent.

02

Action plan

I define a technical plan aligned with your business objectives. Stack, hires, processes, concrete milestones.

03

Execution & follow-up

I implement the plan alongside you. Weekly check-ins, code reviews, architecture decisions. Real leadership, not theoretical consulting.

Who this service is for

  • Pre-seed or seed startups that cannot yet afford a full-time CTO
  • Non-technical founders who need a trusted technology partner
  • Companies that want to assess their architecture before scaling
  • Technical teams that need strategic direction and mentoring

Frequently asked questions

What is the difference from a full-time CTO?

The same strategic and technical leadership, but part-time and without the fixed cost of a C-level hire. Ideal for early-stage startups.

Can you hire my technical team?

Yes. I define profiles, lead the selection process and onboard the team. That is one of the core functions of this service.

What happens when I no longer need a Fractional CTO?

I prepare the transition: I document decisions, train the team and, if needed, help hire a full-time CTO.

How does the day-to-day work?

Weekly check-in meetings, code reviews, async architecture decisions and availability via Slack/email for urgent matters.

How much does a Fractional CTO cost?

It depends on dedication. From €2,500/month for 1–2 days per week. Clear budget before we start, no hidden costs.

I worked with Francesco as backend lead on one of the most technically demanding projects I've been involved in. The stack spanned several very different technologies, and he took ownership of all of them, getting up to speed remarkably fast. What impressed me most was his ability to integrate complex systems on first contact — grasping how unfamiliar pieces fit together and making them work correctly, the first time. That instinct is rare, and it made him the person the team relied on when the hard problems landed (we still rely on him as of now!). I'd gladly work with Francesco again and recommend him to any team that needs a dev who can own complexity rather than be slowed by it.
Federico Magnani CTO, glueglue™
Francesco is a professional who conveys confidence, not only from the point of view of in-depth technical skills but above all thanks to his way of tackling the most complex challenges. I feel confident, in conclusion, in suggesting Francesco as a real added value for any development team.
Mattia Costa CEO, Gitaigo
Francesco is an incredible hardcore worker, efficient and super skilled. He helped my organisation throughout all the development of a industry changer IoT system which required a massive effort on the backend side.
Filippo Quercetti CEO, HubWater
Francesco is an excellent programmer, whose great skills have allowed him to handle a variety of areas with excellent results, especially on the back-end and web development side. He is well suited to teamwork and knows how to respect agreed schedules, even under heavy stress and tight deadlines.
Andrea Rinaldo Principal Application Engineer Manager, Emerson
I strongly recommend Mr. Francesco Antonio Sessa as Back-End Web Developer. During 2016, I had the pleasure to collaborate with Mr. Sessa in the context of various Web Development projects for KCS Media Srls. I was impressed by his capability of capturing and leveraging my personal feedback to the extent of evaluating and reviewing the ongoing services. I also appreciated his capability of smoothly entering and boosting multiSite development, and his very helpful and flexible attitude towards the team. He has many soft skills, a very sharp analytic approach to problem solving, and a natural inclination to exploring new opportunities. Overall, I strongly recommend Mr. Sessa as a skilled as well as trusted professional in Web development and Web maintenance matters.
