James Sinclair - Startup Coach and Founder

Your Journey. Your Way. I'm Here to Help You Build It.

I'm James Sinclair, and I help founders turn chaos into clarity, ideas into execution, and startups into scalable businesses. No fluff. No playbooks. Just your journey, your way. A safe space to explore, organize, and execute, with me as your guide, and biggest advocate.

The Why

Every startup begins as an act of defiance against reality. You see a problem, a gap, a future that doesn't exist yet—and you decide to build it. But the journey from zero to something is brutal. It's messy, uncertain, and full of moments where you'll question everything. That's where I come in.

I've spent over 20 years in the trenches with founders—helping them navigate the chaos, uncover what makes them special, and build businesses that win. My mission is simple: to create a space where you can think bigger, move faster, and execute with precision. A space where you feel safe to ask hard questions, make bold decisions, and build something that's truly yours.

My Expertise

I'm not here to hand you a playbook. I'm here to help you write your own.

Over the years, I've guided ventures through Y Combinator, TechStars, and Capital Factory. I've worked with founders from Uber, Google, Shopify, and LinkedIn, helping them navigate everything from finding product-market fit to scaling globally. I've raised over $50 million, driven $400 million in deal volume, and exited multiple companies.

But this isn't about me. It's about you. Your vision. Your challenges. Your way of doing things. My role is to help you cut through the noise, focus on what matters, and build a business that reflects your unique strengths and values.

My Approach

James Sinclair discussing startup strategy

My approach is rooted in one belief: founders don't need more noise—they need clarity.

I'll challenge you, push you, and hold you accountable, but I'll also create a space where you feel safe to explore, experiment, and grow. Whether you need advice, an opinion, or a straight answer, I'm here to help you navigate the complexities of your journey.

Think of me as your fractional co-founder—someone who's in the trenches with you, helping you make the hard calls and move forward with confidence.

Capital raised for startups

I've worked with hundreds of founders, from first-time entrepreneurs to seasoned executives, helping them raise millions, scale their teams, and launch products that people actually want. My frameworks have been downloaded over 1 million times, and my weekly newsletter reaches over 210,000 founders around the world.

I've also led innovation projects for Fortune 500 companies like SAP, Google, and Coca-Cola, and advised governments in the US, New Zealand, and Brazil on global innovation strategies. But what I'm most proud of is the impact I've had on individual founders—helping them turn their vision into reality, one step at a time.

Beyond Work

When I'm not working with founders, you'll find me off grid. That's it. I believe in lifelong learning, radical honesty, and the power of small, consistent actions to create big change.
