About James Sinclair
I'm James Sinclair, and I help founders turn chaos into clarity, ideas into execution, and startups into scalable businesses.
Over 20 years in the trenches with founders—helping them navigate the chaos, uncover what makes them special, and build businesses that win. I've guided ventures through Y Combinator, TechStars, and Capital Factory, working with founders from Uber, Google, Shopify, and LinkedIn.
"Starting a Startup isn't a feel-good startup manifesto; it's a battle-tested framework built for founders who want results (and are willing to do the hard work)."
