In this episode of the SaaS Operators Podcast, we sat down with Jannik Semmelhaack, founder of Voids.ai, the forecasting platform behind more than €1.5B in revenue for European consumer brands.

Jannik shares how he went from running Philips’ online store to fixing the problem of keeping bestsellers in stock while ops is trapped in Google Sheets, and even with the incredible people on inventory, brands are stocking out.

We ask Jannick why Germany is such a powerful ecom market, how reputation and referrals drove 500 percent growth, their plans for the US, and the mechanics and limitations of forecasting, and the power of faster and more informed decision making.
