Company profile
researched Sep 2026VOIDS, operated by VOIDS Technology GmbH in Hamburg, Germany, sells software for inventory planning and purchasing aimed at consumer and e-commerce brands. The platform covers demand forecasting per SKU, channel and market; inventory and multi-warehouse coverage planning including transfers between locations; replenishment recommendations prioritized by stockout risk and cash requirement; purchase-order management with approvals, delivery status and expected receipts; and supplier performance tracking with on-time-in-full rates, lead-time variance and ETA context. A dashboard aggregates measures such as inventory efficiency, projected out-of-stock impact, overstock value and reorder cash needed.
The company was founded by Jannik Semmelhaack and Tobias Wandersleb, who are also the managing directors, and describes itself as a University of Hamburg spin-off. The name stands for "Vision of intelligent Demand Shaping." Positioning centers on demand shaping — helping customers steer toward revenue and profitability targets — rather than forecasting alone. The founders state customers can be implemented quickly, citing switching "in days, not months" and, in earlier descriptions, implementation in under 24 hours.
Published outcome claims include an average 15x return on investment, roughly 10% higher revenue, about 30% lower inventory value and up to 80% fewer out-of-stocks, with named customer references in sports/events, supplements, streetwear and fashion, textiles, cosmetics and food categories.
Founding story
Jannik Semmelhaack and Tobias Wandersleb met as flatmates in Hamburg. Semmelhaack worked in e-commerce at Philips during a dual study program, where a small team grew revenue from EUR 10 million to EUR 40 million in 24 months and where he observed a lack of AI-driven processes and cross-department coordination; he also cites experience at Deloitte. Wandersleb completed a dual study program at Hauni in Bergedorf, implementing his first forecasting system at age 20. In spring 2020 the two decided to leave their jobs to build a demand management solution, validating the problem and approach with more than 100 companies before founding the company.
Business model
B2B software-as-a-service sold to consumer and e-commerce brands, with the platform delivered as a cloud web application (app.voids.ai). The company reports signing customer contracts with terms of more than 12 months. Startup City Hamburg classifies the business model as B2B.

Traction

Case studies cite HYROX (2,000 SKUs, 30+ markets, out-of-stocks halved, +EUR 4M revenue potential), 6PM (1 buyer, 1,000 SKUs, +EUR 3.8M), Sheko (100+ SKUs, +EUR 4M) and Creamy Fabrics/CFAB (+EUR 15M revenue, +EUR 6.5M free cash flow, SKU availability from 85% to 97%, inventory coverage from 120 to 45 days, 500 to 9,000 SKUs, 1.5 procurement FTEs). Earlier coverage noted a first web app launched within four weeks and several customer contracts longer than 12 months.
Latest developments
The current website markets a consolidated inventory planning and purchasing platform with modules for forecasting, demand shaping, sales targets, replenishment, purchase orders, planning tables, inventory movement analytics and supplier performance, alongside an "Autopilot" and alerting area, and reports 250+ operators and more than EUR 2 billion in planned annual net revenue.
▸Full profile — market position, technology, go-to-market, geography, history, risks & controversies
Market position
The company positions itself as an AI-based planning system for e-commerce brands that lack dedicated planning capability, with the founders stating that their main competition is customers' own internal processes and spreadsheet-based planning rather than rival vendors, and that 70–80% of prospects are not running structured planning. It reports being used daily by more than 250 e-commerce operators covering over EUR 2 billion in annually planned net revenue.
The founders describe demand shaping as the unique element, enabling customers to steer toward their own revenue growth or profitability goals rather than only reacting to forecasts, and point to in-house data science (transformer-based deep learning) rather than only reporting and visualization, plus fast implementation and a focus on a mid-market e-commerce segment they describe as underserved by existing SaaS.
Technology
The forecasting engine is described by the founders as a transformer deep-learning model originating from natural language/NLP work, generating future time series from historical time series and incorporating seasonal and meteorological influences as well as customer planning data. The product combines data processing and visualization with data science outputs such as per-SKU forecasts, reorder quantities, warehouse coverage in days and supplier ratings.
Go-to-market
Direct sales from the company website with offers including a booked "inventory audit," a free out-of-stock check and a product demo. Marketing leans on quantified customer case studies published on the site and on LinkedIn, featuring named brands such as HYROX, 6PM, Sheko, Creamy Fabrics (CFAB), NatureHeart, XbyX, NKM, Neona, Cusbclo and Hensslers. The site is published in German and English.
Growing consumer and e-commerce brands, historically positioned toward medium-sized e-commerce companies with roughly EUR 1–25 million in revenue, and more recently brands scaling toward nine-figure revenue across Amazon, Shopify, B2B and offline channels. Customer categories cited include supplements and nutrition, fashion and streetwear, textiles, cosmetics and skincare, food, and sports and events.
Geography
Headquartered at Hahnenkamp 13, 22765 Hamburg, Germany, with Hamburg as registered office and jurisdiction. Customers operate internationally, with the HYROX case citing merchandising across Europe, the United States and other markets, and the product supporting multi-warehouse planning across locations such as Hamburg, Manchester and New Jersey.
History
The founding company was written up in an EXIST application in February 2022 with support from beyourpilot (later Startup Port) and University of Hamburg mentor Prof. Dr. Michel Clement; a EUR 150,000 funding commitment followed in August 2022. VOIDS Technology GmbH was established in 2022, with incorporation completed in September 2022, and the team was subsequently accepted into the Techstars accelerator. In February 2023 IFB Innovationsstarter listed VOIDS among its newly funded startups. As of April 2023 the company had six employees, three of them studying part-time, and planned hires in software development, sales and marketing via Inno-Ramp-Up funding. A EUR 600,000 pre-seed round was reported in August 2023, after which the team added industry experts and opened new roles. Startup City Hamburg lists 15 employees.
Risks & controversies
Performance figures such as 15x ROI, +10% revenue, −30% inventory value and per-customer revenue and cash-flow gains are company-published claims presented without independent verification in the available material. The founders also note earlier fundraising missteps, including losing two prospective investors due to insufficiently regular updates during the pre-seed process.
