Lessons Learned from Starting a Business Without Market Validation

The speaker left Shopify to start a new company based on advice from Toby. They learned from their first startup that it is important to validate ideas quickly in the market and not rely solely on internal narratives. They regretted not getting a simple prototype and selling to customers sooner, as it took them too long to learn from real customers. The key lesson is to validate ideas quickly and find the fastest way to do so, which often involves directly interacting with potential customers.
