In this episode of Medsider Radio, we sat down with Matthias Hofmann, CEO of Eyebot.

Eyebot is commercializing retail kiosks that deliver quick, efficient vision testing.

Before Eyebot, Matthias led product development at Formlabs and served as an R&D lead at EyeNetra, where he helped bring the first smartphone-based vision test to market. He holds a Ph.D. in Electrical Engineering with graduate work in vision science and optics.

In this interview, Matthias discusses how early missteps informed Eyebot's strategy, how he proved demand before raising capital, and how iterative clinical studies established commercial credibility — along with his unconventional advice on fundraising.

Before we dive into the discussion, I wanted to mention a few things:
