Jobbeschreibung

We maximize product availability with minimal cashflow investment in 1 / 10 of the time. We solve a real problem for SMEs. With AI.

VOIDS is the leading forecasting and inventory management software solution for D2C brands. The VOIDS platform automates accurate product-level demand forecasting to proactively identify risks such as inventory inefficiencies (e.g., out-of-stocks) and take recommended actions to eliminate them before they occur. We help e-commerce brands achieve 98% inventory efficiency, 20x ROI, and six-figure cash profits in a matter of weeks. 50+ success stories, including FC Bayern, 6pm, Rosental, and Blackroll confirm this. Since our product launch in June 2023, we’ve achieved approximately 300% growth over the past year, and we’re now positioned to double our ARR by the end of 2025.

At VOIDS, you'll find a game-changing personal growth opportunity if you are driven, fast-paced, and passionate about challenging the status quo. Embrace the opportunity to take direct ownership of scaling our AI platform's success. Work alongside the team and co-founders Jannik and Tobias, who bring a wealth of experience in e-commerce growth and AI-based demand forecasting.
