Fit to Scale · GTM for founder-led B2B SaaS
You need someone who has built the system before. You don't need them five days a week at a full exec salary.
At Seed to Series A the gap is rarely effort — it's senior judgment on where the GTM actually breaks. A fractional CSO gives you architecture-level decisions and hands-on execution support without the comp, equity and risk of a premature full-time hire.
Plenty of advisors will tell you what good looks like. Far fewer will sit inside the six levers with you, make the hard calls (including what to kill), and stay accountable to the outcome.
A fractional CSO is senior enough to decide and present enough to execute — the middle ground between a one-off audit and a premature six-figure hire.
Not advice on the side — accountable design and execution across:
Decided and documented, not debated.
Ruthless focus, including saying no to features and segments.
The commercial logic that makes deals defensible.
The gate that protects your pipeline's integrity.
Architecture, not guesswork.
Owned end-to-end, then handed to the team.
Fractional senior GTM work means making the calls a CSO makes — defining ICP, killing the wrong product line, restructuring the model. Here's what that produced.
Situation. Post-crisis team running three products across B2C and B2B; founder-driven, opportunistic sales; no clear ICP or value proposition.
Move. We defined a sharp ICP, shut down the B2C line, and merged two products into one focused offering.
Result. €2.5M new investment secured, merger with a competitor, €2M pipeline generated, €600K ARR closed.
Situation. Highly customised sales software requiring per-client hardware adaptation; slow time-to-market, only large projects viable, hard to close without traction.
Move. We shifted from custom builds to a browser-based SaaS product with limited customisation and a scalable subscription model.
Result. First €200K client closed in 3 months; entry into larger, reputable insurance accounts.
Engagements typically start with the 10-week diagnosis to set the system, then continue as ongoing fractional execution support. You get senior ownership; you don't carry a full-time exec on the cap table.
We do not promise:
We deliver:
The goal is not to look scalable — the goal is to become scalable.
The 10-week Fit-to-Scale program is not a pitch call. It's a structured analysis of where your pipeline breaks, a layout of how to fix the misalignment, and a system to scale sales. If there's no fit, I'll tell you directly.
