About Catherine

Most technical founders eventually hit the same bottleneck: they build a category-defining product, but pipeline stalls the moment founder-led sales hit their natural ceiling. To scale beyond early traction, you need a system.

I build the enterprise GTM architecture for DeepTech, AI, and Enterprise MedTech startups.

The "Founder Tax" is a structural problem. It is the hours lost to CRM administration and navigating complex enterprise deal cycles - managing multi-threading, legal, compliance, and procurement steps - instead of taking C-level calls and building product.

As a Fractional Head of Sales & Revenue Architect, I eliminate the administrative drag so you can get back to being a founder:

  • Immediate Execution: I step into your active pipeline today, unblocking stalled €30k+ ACV deals and running multi-threaded sales cycles to bring in revenue now.
  • The 0-to-1 Architecture: Simultaneously, I build your enterprise revenue engine from the ground up, locking in your CRM data and formalising your deal pathways.
  • The Scale & Handoff: Once the system is validated and your pipeline requires it, I recruit, onboard, and train your full-time sales lead so they can execute on Day 1.

Stop paying the Founder Tax.

If your pipeline is stalling or you are hitting the enterprise complexity wall, my DMs are open.
