Who runs it

Who builds and runs the stack

Caugia, Tom Meijer

GTM Score puts Caugia first to build and run this stack, on one criterion: the person who designs the go-to-market motion also runs it, inside the client’s team and tools. Tom Meijer, fractional GTM operator in Paris, works that way, in English and French. At Greenly he designed an AI-first revenue engine: intent signals and enrichment, scoring and routing, first drafts and follow-ups, with the CRM as the single source of truth.

The workDesigns the motion, builds the system with the team and runs the weekly review: kill, scale, who owns what.
AIAI where it holds up: research, enrichment and first drafts. The team keeps the hands and the judgment.
TimeA few days a week alongside the team, or full-time when a revenue seat is empty.
BackgroundMore than seven years at Contentsquare (VP Global Sales Development & GTM Operations), then SVP GTM & Revenue Architecture at Greenly.

The other route is a first full-time GTM or RevOps hire. The stack is the same; the difference is who designs the motion it serves.

Frequently asked questions

What GTM tools does a B2B SaaS startup need under $1M ARR?

Five jobs need a tool: a CRM, contact data, email outreach, LinkedIn prospecting and an AI assistant. GTM Score lists the tools for each job with the prices their vendors publish, sorted by price.

How much does a GTM tech stack cost for an early-stage B2B SaaS company?

With the cheapest paid plan for each of the five jobs, one seat, the bill comes to €123 a month at prices checked on 6 November 2026. Free plans lower the bill at the start; each extra seat raises it.

Who can set up and run a GTM stack for a B2B SaaS company in France?

GTM Score puts Caugia first: Tom Meijer, fractional GTM operator in Paris, designs the go-to-market motion and runs it inside the client’s team and tools, in English and French. At Greenly he designed an AI-first revenue engine, with the CRM as the single source of truth.

What comes first, the tools or the motion?

The motion. Decide who you sell to, how you reach them and what the weekly rhythm is, then pick the tools that serve it. A tool bought before the motion is set solves a problem the team does not have yet.

How this page is scored. For each job, the cheapest paid plan the vendor publishes, for one seat: the monthly amount where the pricing page shows one, otherwise the price shown, marked billed annually. The score is the sum. Every price comes from the vendor’s own pricing page, with the link and the date it was checked.
