What if you could compress a decade of startup learning into 90 days, and leverage AI to do it?

Most founders fail not because they lack brilliant ideas, but because they build solutions before validating that anyone actually needs them. They confuse activity with progress, sales with marketing, and “traction” with sustainable growth. After mentoring over 1,000 startup founders across Japan, Saudi Arabia, Canada, the US, and beyond, Tash Jefferies has seen these patterns destroy promising ventures—repeatedly.

But the game has changed. AI tools like ChatGPT, Gemini, and Copilot have fundamentally shifted what’s possible for founders. What used to take months of research, testing, and iteration can now happen in minutes. The entrepreneurs who understand this and know how to leverage it properly are building profitable businesses in 8-12 months, not 8-12 years.

SOLVE PROBLEMS. MAKE MONEY. REPEAT. is the straight-talking, no-fluff guide that shows you exactly how to do it. This isn’t about generating generic AI content or chasing unicorn status. It’s about using AI strategically to validate real market needs, build sustainable systems, and scale with intention.

This book is for founders who:

• Want to move fast without burning cash on unvalidated ideas
• Need to understand their sales funnels, unit economics, and growth metrics
• Are ready to leverage AI tools properly, not just dabble with them
• Seek proven frameworks over motivational platitudes
• Value authenticity, resilience, and human-centered business building

You’ll learn how to:

• Validate market need in 90 days or less using AI-powered research
• Build repeatable sales systems before outsourcing anything
• Avoid the 10+ cardinal sins that kill 80% of startups
• Create proper sales playbooks that scale your team
• Use AI to compress Jobs-To-Be-Done frameworks from weeks into minutes
• Develop a founder mindset and resilience for the long game

Written in Tash’s signature energetic voice, complete with Drake-inspired quotes, real founder stories, and tactical exercises—this book gives you the tools, tips, and truth bombs you need to build something the world actually wants.
