Hi, I'm Thom Cummings

I've spent 20+ years building and leading marketing at tech companies — from early stage through to scale. SoundCloud, Grover, Pitch, and most recently Prolific, driving 10-100x growth and building world-class brands.

Inference is my practice. It sits at the intersection of marketing strategy, systems thinking, and AI — the three things I believe will define the next era of how companies grow.

I write about what I'm learning as I rebuild my own practice with AI (annotations), build marketing systems as products (blueprints), and work directly with companies navigating this shift (collaborations).

Based in Brighton, UK.
