Bruno Didier ordered dinner through Grubhub, waited two hours, and ended up buying pizza from a grocery store. That terrible delivery experience led him to build a niche SaaS platform for restaurant delivery management that grew to $2M ARR with 2,000 customers. Bruno reveals how a dinner with a stranger in Lyon led to Y Combinator and how asking for advice worked better than any sales pitch. Bruno went door to door to every restaurant in his city, asking managers for help building the right niche SaaS product. When he pitched as a salesperson, they said "no time." When he asked as a student, they invited him in. A chance dinner with Twitch co-founder Michael Seibel led to Y Combinator acceptance for this vertical SaaS company - something Bruno would never have pursued on his own. Bruno Didier is the founder and CEO of Y Combinator startup Trackin. The niche SaaS platform connects restaurant managers, drivers, and customers to improve delivery operations across San Francisco, New York, Chicago, the UK, France, and Italy. 🔑 Key Lessons 🤝 Ask for advice instead of selling to win niche SaaS customers: Bruno went door to door asking restaurant managers for help building the right product. When he pitched as a salesperson, they refused. When he asked as a student, they invited him in. 🎯 Watch customers use your niche SaaS product in person: Bruno handed managers the mouse and watched silently. He saw them miss buttons and struggle with workflows - insights no survey or phone call could provide. 🧠 One dinner can change a niche market SaaS founder's trajectory: Bruno canceled London meetings and spent 200 euros changing train tickets to meet Michael Seibel. That dinner led to Y Combinator acceptance. 💰 Email newsletters convert cold prospects into vertical SaaS customers over months: Trackin sent feature updates to cold restaurant contacts. Some leads ignored emails for six months, then one feature triggered them to sign up immediately. 🔄 Build a second product to become your own micro SaaS customer: MobyDish, a catering marketplace, ran on Trackin's technology. Being a daily user revealed pain points faster than external customer feedback alone.
