Gustaf Alströmer explains that startups should first find product-market fit by doing hands-on work that does not scale and learning directly from customers. He recommends measuring retention around the product’s core value to judge whether people keep using it. Once retention is strong, startups can improve product conversion and focus on the growth channels that fit their customers and business. For larger teams, A/B testing helps settle product decisions with evidence instead of opinion.
