Before seeking major funding, Elysian validated its radical aircraft design with skeptical professors from TU Delft and MIT. Winning over these experts provided the critical credibility and third-party proof needed to build investor confidence in their unproven deep-tech concept.

During Ethic's long build phase before traction, the founder found it crucial to ignore external validation signals like other companies' funding announcements. The key to surviving this lonely period is a relentless daily focus on execution and solving customer problems, not chasing industry hype.

The founder hesitated to take his father-in-law's investment, not fearing financial loss, but the long-term social strain at family gatherings if it failed. His wife reframed this by pointing out the potential resentment if the company succeeded and he'd refused the investment, highlighting the complex emotional dynamics.

Value-add isn't a pitch deck slide. Truly helpful investors are either former operators who can empathize with the 0-to-1 struggle, or they actively help you get your first customers. They are the first call in a crisis or the ones who will vouch for you on a reference call when you have no other credibility.

A founder credited his accelerator's grueling schedule—pitching to 20 investors weekly with harsh feedback—as a transformative experience. This intense repetition wasn't just for fundraising; it was a powerful training ground that polished his core sales and communication skills for all future business dealings.

During validation calls for Merge, prospective customers expressed extreme annoyance with the status quo but were skeptical the founders could technically solve it. This combination was the ultimate signal: the pain was immense, and a successful solution would be highly defensible and valuable.

The number one reason founders fail is not a lack of competence but a crisis of confidence that leads to hesitation. They see what needs to be done but delay, bogged down by excuses. In a fast-moving environment, a smart decision made too late is no longer a smart decision.

The motivation to start a company wasn't about a guaranteed outcome but about embracing the ultimate test of one's capabilities. The realization that most founders, regardless of experience, are figuring it out as they go is empowering. It reframes the founder journey from a path for experts to a challenge for the determined.

To truly validate their idea, Moonshot AI's founders deliberately sought negative feedback. This approach of "trying to get the no's" ensures honest market signals, helping them avoid the trap of false positive validation from contacts who are just being polite.
