fractional cto · chief product

Shaping the next stage of your B2B SaaS, together with your product and engineering team.

Fractional, hands-on. Working with SaaS teams from first hire to around 40 people. Typically six to twelve months.

— approach

Two ways I work.

01For SaaS owners and investors

Fractional CTO or Chief Product

The bottleneck is rarely the technical team. Decision making and key knowledge is often concentrated in a few key people. I take the CTO or Chief Product seat and put in the product and engineering systems that take those decisions off those people. The flywheel turns faster because it no longer waits for one person.

— one of the systems I put in

01

Product idea

It starts with an idea, about how you can improve the product you offer.

  • Your team
02

Spec

Before handing over the idea to development, think the problem through. Writing is a very effective way to think things through. Do this exercise with multiple disciplines involved.

  • Google Docs
03

Design

When the problem is clear, create a low-fidelity mockup of what you're going to build. Low-fidelity means quick and dirty, but also cheap to throw away. (Which will happen a lot.)

  • Figma
  • Claude Design
04

Stakeholder feedback

Use your low-fidelity prototype to learn more about the problem and the potential solution.

  • Unmoderated user-testing
  • One-question surveys
loop

Learning

Based on user feedback, update your problem statement and solution direction.

  • Product trio
05

Prioritization

When it's clear what to build and the amount of work that is involved, prioritize the features that will have the biggest impact on the business.

  • Featurebase
  • Linear
  • Canny
06

Implementation

The actual implementation of your change, done by the development team.

  • SCRUM
  • Claude Code
  • Cursor
07

Release

Roll out to your actual users. Involves more than just deploying the code, but also marketing, sales, and customer support.

  • Featurebase
  • Canny
  • Feature flags
loop

Product analytics

Placeholder for Product analytics — a sentence or two on how usage data feeds the next idea without waiting for the human loop.

  • PostHog
  • Roll your own
08

Feedback

Placeholder for Feedback — a sentence or two on what happens here, who owns it, and what it produces.

  • Zendesk
  • Customer support system
02For traditional business owners

MVP development

You already run a business and you have an idea for a digital product. Before you hire anyone to build and scale it, I help you validate the idea with a actual working product.

— the product startup journey

I'll build the product for the first two phases.

  2. 02Problem–solution fit
  3. 03Product–market fit
  4. 04Scale
01

Problem discovery

Before anything is built. Typical work here is problem interviews, sitting with people while they do the job, mapping how the work happens today, and writing down who feels the pain, how often, and what it costs. Until that is specific, there is nothing to ship.

  • Problem interviews
  • Process mapping
  • Pain quantification
  • Stakeholder mapping
02

Problem–solution fit

When the problem is clear, you have to test whether your solution actually solves their problem. Typically you do this with prototypes that are easy to throw away.

  • Concept tests
  • Low-fi prototypes
  • Minimum viable product
  • First users
  • Pricing talks
03

Product–market fit

This phase is about finding out whether you the problem you have found at your initial customers, is also a problem for the larger market. You'll need to tweak your processes and your product before you can scale.

  • Retention
  • Repeatable sales
  • Channel tests
04

Scale

Hiring, structuring the processes, and finding more channels. Typical once the company already works. To make sure you can capture your market.

— about

One person. In the repo and in the room.

I run Count Code, a one-person practice in 's-Hertogenbosch, NL. I take fractional CTO and chief product seats, positions where you need someone to discuss strategy whilst still being able to open a pull request.

It is not an agency. I typically take on two companies at a time, for a duration of six to twelve months.
