I help early-stage founders get funded and build repeatable growth that attracts serious investment. As a 3× founder and Revenue Leader, I run an accelerator backed by VCs in the US and Europe, helping startups raise early-stage rounds, refine their story, and prove commercial traction. I’ve worked with founders across both continents to bridge the gap between strategy, execution, and capital. What that means for you: -You’ll access investor networks and accelerators across the US, UK, and EU. -You’ll position your company and deck to win investor confidence. -You’ll validate demand and prove traction before the round - not after. -You’ll build a repeatable GTM system that drives growth and credibility. -You’ll raise faster — with structure, momentum, and clarity. New to Upwork, but not to getting founders funded and growing. Check me out on LI: /tobylyons
