We're rethinking human-AI interaction from first principles to be more natural, enabling the next generation of conversational AI products. Today's AI conversations feel constrained because they rely on a turn-based interaction model—speak, wait, listen, repeat. Real human dialogue doesn't work this way. It's fluid, overlapping, and full of real-time feedback. True conversational fluency requires the ability to interrupt, provide instant reactions, and engage in the dynamic back-and-forth that characterizes authentic communication. We're building a full-duplex conversational speech model and developer-friendly SDKs for natural, simultaneous two-way communication with AI agents.

We also believe great work happens when people enjoy being around each other, so we value team trips, a good atmosphere at the office, and the occasional Friday afternoon beer.

Leftovers is a peer-to-peer marketplace connecting home cooks with neighbours who want affordable, authentic, home-cooked meals, starting in Copenhagen. We all know how expensive eating out in Denmark can be. And cooking takes time and skill most people don't have. The result? Overpriced delivery, repetitive convenience food, inefficiency and waste. Meanwhile, thousands of skilled home cooks (food influencers, aspiring chefs, international residents cooking family recipes) have excess capacity and no easy way to monetise or share it. Leftovers closes that gap. Through the Leftovers app (live on iOS and Android), neighbours browse daily home-cooked meals from local cooks, order affordable portions (50–100 DKK), and collect locally. Cooks get flexible, high-margin income and a micro-brand for their cuisine. Customers get real food, at fair prices, with zero cooking required. All while building community and addressing waste. We've just launched a Kickstarter pilot in partnership with CBS Housing (Copenhagen Business School's student residences) and are actively securing further co-living and student housing partnerships to validate and grow the model. Denmark's regulatory environment for small-scale home food sales makes it feasible. I noticed the opportunity while living in a student dorm in Copenhagen last year, where I was constantly choosing between expensive takeaway and my own basic cooking, while talented students across the hallway were cooking incredible family recipes every day. We tried sharing food amongst ourselves, and it worked. Surveys across students, young professionals, and families confirmed the need. I've since come across many examples of successful local food sharing initiatives, but no platform that coordinates it. Leftovers isn't just a platform for sharing home-cooked meals. It unlocks idle kitchen capacity, empowers home cooks, makes food more affordable, improves access to authentic local produce, fights waste, and helps build local community. The long-term vision is city-by-city expansion across Denmark, Scandinavia and Europe, where local food regulations make sense. I'm now looking for a co-founder with a passion for community-building and marketing to help turn early traction into a movement. Equity on the table. Because sharing tastes better. leftovers.food admin@leftovers.food @leftovers.cph

GERM Bikes (Gravel, Electric, Road, Mountain) is an asset-light, tech-driven platform transforming premium bike retail and mobile maintenance. We bridge the gap between high-margin e-commerce and on-demand doorstep service. The Problem: The cycling market has shifted toward heavy electric cargo bikes and premium performance machines. These high-value assets are an absolute nightmare for customers to transport to traditional repair shops, where they face long wait times and unmotivated staff. Meanwhile, corporate mobile competitors are drowning in heavy overhead and corporate debt. The Solution: We vertically integrate the entire customer lifecycle. Customers buy premium bikes directly from our platform, receive expert doorstep assembly/fitting, and stay locked into our ecosystem through smart maintenance subscriptions. By utilizing a database of 130,000+ bike profiles and custom routing software, we run a hyper-efficient, highly profitable operation. To scale rapidly without burning capital on corporate fleets, we leverage a low-barrier franchise model that turns elite mechanics into motivated local owners. GERM Bikes matches traditional shop prices while unlocking massive margins and a predictable, recurring revenue engine.

Cap is an AI-native operating system for modern venture capital. Founded in 2023 in Copenhagen, we’re building a connected workspace where investors get the full picture in real time, without juggling multiple tools. Our journey started with a simple but powerful observation: today’s investors don’t lack data, they lack structured insight. Instead of switching between Affinity, Todoist, Notion and endless spreadsheets, Cap gives venture capital firms a single, structured platform that organizes, understands, and prioritizes information. This AI-native foundation is what sets us apart. Where others layer AI on top of existing clutter, Cap was designed from day one to structure complexity into clarity. Our platform continuously adapts, ensuring VCs can move faster, act with confidence, and lead with clarity in an increasingly competitive investment landscape. At Cap, we combine engineering excellence, ambition, and entrepreneurial drive to reimagine how venture capital operates. We are still at the beginning of our story, but with early traction across the Europe and the US, we’re building a product and a team with global impact in mind.

Herodesk is a fully remote tech startup based in Denmark. We have created a new customer service platform for small and mid-sized businesses and webshops. Our mission is to make customer service easy. It should be easy for our customers to use Herodesk, which in turn should make it easy for their customers to get the help they need. To achieve that, we've created a helpdesk and live-chat product that is simpler and cheaper than the alternatives. Our product was launched in September 2023. Now, a year later, we have close to 100 paying customers, with more being onboarded weekly. Our founder, Anders Eiler, has previously co-founded SpeedGaming and Meebox, and led the DanDomain E-commerce division (a >€10M rev. division). Based on those learnings, it was clear that a simple and affordable customer service platform was missing for small and mid-sized businesses. So in the summer of 2023, he founded Herodesk and entered a deep-red ocean with many established competitors, but with a mission to make great helpdesk software available for the masses. We've found product market fit, and it's time to scale the businesses nationally and internationally.

Læsk is out to challenge the soda industry by offering fermented soft drinks that has less sugar and less calories than conventional sodas. Through fermentation and being selective with ingrediens, we create well-balanced drinks without alcohol that are less sweet. The kombucha category is fairly new and despite Læsk being the leading brand in Denmark, represented in 7Eleven, Coop and lots of restaurants and cafes across the country, there's still a lot of customer education to be made. It is a fun journey and we are driven by the opportunity to get people to make better choices for themselves. Founder Line started Læsk because she thought the soda category was boring and drinks were too sweet. Cheers to a healthier soda!

We are a legal tech start-up that helps professionals solve legal issues through visual analysis. Imagine a whiteboard that can solve legal issues. To elaborate on this, we have created a SaaS tool where legal professionals can collaborate, analyze, and draft legal reports. Currently, we provide four different services within our three pillars of value: 1) Easy access to data 2) Automated assistance (red-flagging) 3) Document Automation We a solving a growing demand within the legal sector to work more effectively. Clients are pushing for capped or fixed fees, which has lead the industry to look for smart ways to work more efficiently. Further, the legal sector has a quite low technology adoption rate. We want to help the industry work more efficiently through a great and intuitive UX and through genuine value creation. Our end goal and mission is to go beyond the value creation for lawyers and accountants and also create real value for small and medium-sized businesses. This we aim to accomplish through an AI Lawyer. However, there is probably a really long time before this is a reality. The AI lawyer should work on top of the existing platform that we already have created and the red-flagging functionality build into the system. We have built an algorithm for finding and recognizing patterns on the "whiteboard". Thus, if we through NLP and deep learning are able to create graph data structures through text analysis, we can generate red flags from legal texts. This is our goal: helping advisers and clients with software created with a strong industry insight.

Sisi Copenhagen is a Danish direct-to-consumer jewelry brand building lasting jewelry for life's most meaningful moments, sold exclusively through channels we own. Our assortment is broad by design, but within the bridal segment we are expanding fast. No retailers, no marketplaces, no middlemen. Bootstrapped since 2017 and among the fastest-growing brands in the established jewelry scene. The jewelry industry runs on markups, distance, and inertia. Legacy brands stack middleman margins onto every piece, sell through cold and transactional channels where no one is accountable after the purchase, and move slowly in an industry that rarely questions how it operates. The result: jewelry that costs more than it should, bought through experiences that feel impersonal at exactly the moments that matter most, an engagement, an anniversary, a gift meant to say what words can't. We think the people buying jewelry for the meaningful moments in their lives deserve better than that. We own the entire chain. We design our own pieces and work directly with the best workshops in the world, so there are no supply-chain middlemen inflating the price. We sell only through our own channels, which means every relationship is direct: the person who advises on a diamond ring and the person who handles a question afterward both work at Sisi Copenhagen. Operations, customer service, and marketing are run in-house, with focused external support where it makes sense. We're also spearheading lab-grown diamonds, the best current vehicle for offering fine jewelry at honest prices, and we treat experience as a core differentiator. We're constantly building better ways to buy jewelry across both the digital and physical space, from the online journey to in-store and video consultations. Experience innovation is where a lot of our energy goes. This is a lean, owned, constantly refined model. Revenue grew from 6M to roughly 75M DKK in four years, we've won four consecutive Gazelle Awards, and we've done all of it with zero external funding. That independence is a deliberate strategy: we grow on our own terms, reinvest in the business, and answer to our customers rather than investors. Sisi started with Vivi, who grew up around her mother's jewelry trade and built the company alone for years: full-time job by day, the business by night, her own money on the line. Christian joined from the entrepreneurial side, drawn to building something from nothing. We've grown the brand through the same milestones it marks for others: partnership, parenthood, building a home. We lead without hierarchy and hire people who want real ownership over what they build, whether that's shaping how the company runs or architecting the systems and processes behind it. If you're curious, self-driven, and want to see your work land directly on the business, you'll fit here.
