Gus Bartholomew

I'm Gus, a commercial and operations leader who has spent the last decade founding and scaling B2B SaaS and marketplace startups, as both a founder and an operator. I've started multiple businesses and worked inside many Seed to Series A companies, so I've seen the traction-to-scale journey from every angle. I build the core business systems across operations, sales, marketing and customer success that deliver results now and lay the groundwork for lasting growth. I've assembled and led high-performing teams and tech stacks for both enterprise sales and product-led (PLG) sales motions. A few things I've done: Co-Founder at Leafr, the leading global marketplace for sustainability consultants — applied AI to scale supply and demand and built the commercial engine (40% QoQ growth, 45% repeat clients). Co-Founder & CEO of SupplyCompass — raised £2.5m, scaled the team 0→25 across the UK and India. Head of Revenue & Ops at Grain (post-$20M Series A; Tiger Global, Slack, Zoom) — grew weekly demos 400% and the customer base 50% in six months.
