Every startup has a story worth hearing. Some are chasing their first customers, others are figuring out how to handle their next million. And somewhere along the way, nearly every founder faces a question that can't be solved by ambition alone. On November 4, TechCrunch Founder Summit 2026 will fill Boston with people who know these challenges firsthand. Founders, investors, and tech leaders will get together to talk funding, product decisions, growth, and all the lessons that rarely make it into a pitch deck.
Egor Grischenko, Co-founder & VP of Business Development at Innowise, will be joining the crowd, and he's especially keen to hear what's keeping founders busy these days. A product that's outgrown its original architecture? An AI feature that's proving trickier to launch than expected? An engineering team struggling to keep pace with demand? We've helped companies work through challenges like these, and we'd love to compare notes, share a few lessons from our own projects, and see where our engineering expertise could come in handy.
Will you be in Boston? Tell Egor what you're building, what's working, and what you'd happily never troubleshoot again. We look forward to meeting you!
