spotLESS Materials logo

spotLESS Materials

Repellent coatings without PFAS

Surface fouling is a costly challenge across industries, impacting medical consumables, diagnostic devices, and automotive components. Contamination from substances like mud, ice, and sludge can compromise performance and lead to frequent cleaning, repairs, and replacements. Our PFAS-free coating, which we first launched as a consumer product, has quickly expanded into industrial partnerships. It dramatically reduces contamination on critical surfaces such as glass, metal, ceramic, and now plastics too. Whether for medical devices or automotive components, our coating protects against surface fouling Currently our coatings work best on glass, metal, and ceramic surfaces.

stagewise logo

stagewise

The frontend coding agent for real codebases.

stagewise builds an open-source frontend coding agent for real codebases. We enable backend devs, designers and product managers to build pretty and functional web apps in a simple and visually guided manner - no matter the used tech stack. stagewise lives right inside your browser, makes changes in your local codebase and is compatible with all kinds of frameworks and setups - allowing it to be retrofitted into any existing project. Our agent enables you to show and tell what you want to change - all while using your app on localhost and without having to switch to external tools. Making changes is as easy as selecting elements, giving a simple prompt like “make it green and put it in the top right corner”, and immediately seeing the result. We're two founders from Germany who met while working at a B2B SaaS startup. With Glenn's background in building dev tools for enterpries (Rheinmetall, Miele), as well as Julians experience in building web apps used by thousands (saasmetrix, strukto.io), we have the unique blend of experience and product sense needed to build this. After making our initial launch with the open-sourced toolbar that puts your favorite coding agent right inside your browser and going viral with it, we’re now launching a high-speed coding agent dedicated to frontend development - taking our product and the experience of our users to the next level. Our vision is to replace frontend devs completely, by gradually enabling both the backend devs, but also less technical designers and product managers to create well-designed applications. We start with developers who lack design experience, but our ultimate goal is to change how products are built.

telli is building AI voice agents that convert leads into sales opportunities for B2C companies. For example, a leading home-buying platform is using telli to fully automate their pre-qualification. We are serving customers in energy, real estate, medical products, and home services. You might think that these B2C companies want to do more self-serve and less outreach. But the truth is outbound calls are what really drive conversion. Historically, managing these calls has been complex and expensive—costing companies hundreds of thousands of dollars. With telli, for the first time, B2C companies can automate the role of a pre-sales agent, end to end.

truemetrics logo

truemetrics

We show couriers where to park and enter a building.

truemetrics helps logistics companies to find their customer's faster. By detecting and mapping entrances, we help GLS, a key logistics company in Europe, save 32.7 seconds on each delivery. The way couriers navigate is broken. “You Have Arrived At Your Destination!” — or so Google Maps thinks. In reality, the way couriers navigate is broken: No parking, hard-to-find entrances, and labyrinth-like apartment and office complexes can turn the last meters of delivery into a time-consuming puzzle. truemetrics provides parking positions and entrance locations to enable faster drop-offs. Our data is generated by analyzing sensor data from drivers' smartphones, allowing truemetrics to identify precise parking and entrance locations, thereby simplifying the last meters of delivery.

twoplus fertility

An effective home-use fertility treatment for natural conception

We are making a new fertility treatment that infertile couples can order with a click of a button to help them conceive at home. Our technology increases the likelihood of pregnancy by guiding significantly higher number of sperms towards the ovum using a proprietary combination of surface features and microenvironment optimization. The fertility treatments available today, such as in-vitro fertilization (IVF) and intra-uterine insemination (IUI), are psychologically and financially draining and come with considerable treatment-associated risks. Furthermore, over 25 million women of reproductive age in the US have limited nearby access to fertility treatment.
