Where: YesSF — San Francisco, CA
Presented by: Wisdom Partners, Sway, & YesSF
Finding product-market fit is one of the most important and misunderstood stages of building a company. Many founders spend months building features, launching campaigns, and raising capital before realizing the core problem has not been fully validated.
At this Founder Real Talk session, experienced founders and operators will share honest lessons from the process of finding and refining product-market fit.
What We’ll Cover
Topics we will cover include:
• How to recognize early signals of product-market fit
• Common mistakes founders make while searching for it
• When to pivot, iterate, or double down on your current direction
• How to gather meaningful customer feedback that actually informs product decisions
• The role of marketing and distribution before and after product-market fit
• What growth looks like once the right market and product begin to align
Expect practical insights, candid stories, and lessons learned from founders who have navigated this process firsthand.
Who Should Attend
This conversation is designed for:
• Early-stage founders building their first product
• Startup teams preparing to launch or refine a product
• Operators responsible for growth, product, or go-to-market strategy
• Investors and advisors interested in how companies reach product-market fit
• Anyone curious about how successful startups actually find traction
Whether you are still validating an idea or working to scale something that is already in market, this session will offer valuable perspective on one of the most critical stages of building a company.
