| Is there enough charge in the car for the next trip? When will the vehicle go out of charge? What is the optimal route? These are questions that arise every day when driving an EV. And these just get a lot worse if we are not talking about individual vehicles but 100s of them like electric van delivery fleets, public transport with e-buses or e-carcompany fleets. For them, electric vehicles are much more expensive and difficult to operate than normal petrol or diesel ones, not to mention the constant fear of running out of charge with 100s of vehicles at the same time. Volteum solves these issues for them every day.At Volteum our goal is to enable every company to use EVs as easily, effectively and economically as internal combustion engine vehicles. For this we are developing a software with which fleet operators can optimize their vehicles every day. The product has three main pillars: Firstly, we model and predict the energy consumption and the battery state of charge along the routes with our EV simulation engine. Secondly, based on this we plan optimal trips for the vehicles taking into account the charging needs, time, distance and costs as well. Thirdly, we also manage the daily tasks of the fleet and optimize their operation based on live data.With Volteum electric fleets save money as we optimize their fleet composition, the daily tasks, routes and the charging needs cost-effectively. They can also make sure none of the vehicles will go out of charge thanks to our simulation engine. Last but not least we save loads of human resources, manual calculations and planning with our algorithms. With this we can ensure that all tasks and routes will be covered just as easily and comfortably as with their old vehicles. | $2.9M / Seed / Jun 08, 2026 | ||

| Miros utilizes advanced AI technology to analyze shopper behaviors, identifying key interactions like scrolls and clicks to enhance user experience. This innovative feature allows customers to browse the store without typing, improving engagement and simplifying the shopping process. Miros also offers insights and expert blogging on leveraging AIfor product discovery to help grow e-commerce businesses. ---eCommerce loses half of its sales because in this industry nobody knows how to make the products findable.If you can’t find, you can’t buy. No universal taxonomy exists to describe visual items. Shoppers do not know the right words to search for what they like.Meanwhile, because you can’t filter products by how much you like them, you’ll have to browse thousands of products – many of which you’ll dislike. When shopping feels tedious, the shopper quits.Miros gives shoppers a new language to express what they are looking for - far richer and more accurate than any existing search technology. | $6.6M / Seed / Nov 05, 2024 | ||
