Expanding to other geographies and marketplaces is a massive growth lever for brands and manufacturers, but it’s complex and resource-intensive. Omnidock makes it effortless for merchants to sell on multiple marketplaces by acting as their merchant of record. Brands simply plug into our operating system, which reads their catalog, assesses marketplace eligibility, and auto-launches their products through our pre-vetted marketplace accounts. We handle all transactions on their behalf, removing the challenges and complexities of multi-marketplace selling

Voker is a no-code platform that empowers product teams to build AI features in minutes without involving engineers. Companies like Lull.com and Dutch.com are using our platform to improve their consumer experience and retention. Alex and Tyler met at a high-growth E-Commerce startup where Tyler was running Technology & Data. Together, they built AI products that bootstrapped the company profitably to $100MM in Revenue. Alex experienced firsthand the broken developer experience in AI while building enterprise infrastructure at Yardi. Even with a dedicated ML team, it took too much time to build simple AI features. It was clear that if large companies were struggling with this, SMBs would definitely be left behind. We went directly to our network of SMB operators and found our hunch was correct. Within a week we had two paying customers even before launching our first prototype. Voker is built for product specialists who know they can delight their users with AI but can't spend engineering bandwidth on building those features. By making AI accessible and practical, Voker helps these businesses profit from this new wave of innovation.

Tandem

Project Management

The pandemic reduced office use nationwide by 50%, and tenants have been left to deal with highly inflexible, long term lease agreements that don’t fit today’s office use patterns. The traditional brokerage model works great for big spaces and long terms. But when you want to talk smaller units, short term lengths, shared and common areas, you’re out of luck. Tandem is an AI-enabled office leasing platform. We’re using technology to unlock flexible agreements in quality spaces. Our AI co-pilot enables a white-glove-quality B2B office search experience, with a fraction of the human labor typically required. Today we’re serving two primary markets — NY & SF, with hundreds of active Hosts in each. We’ve helped match more than 350 companies and have seen double-digit month-over-month growth.

Yoneda Labs

Project Management

Yoneda Labs provides software to help chemists optimise reactions. When chemists make a drug or a material, we help them figure out the best reaction parameters such as temperature, concentration and catalyst. When Jan was working at chemical labs, he experienced the struggle of spending weeks guessing reaction conditions. We then started experimenting with ML to speed up the process. Now, as a team of three friends from the University of Cambridge, we’ve spent the last month combining our domain expertise in Computer Science, Machine Learning and Chemistry to develop state of the art models for reaction optimisation. Although ML is becoming well established in other fields, current chemical models generalise poorly and require lots of programming experience. We make our models easily accessible to chemists in the lab. Finding the right conditions quickly allows pharmaceutical companies to test more drugs, and finding better optima makes manufacturing process cheaper and more environmentally friendly.

Toolify

Project Management

Toolify is dev-first internal tooling. At some point, companies using low-code builders hit a brick wall, and are bogged down by their limitations rather quickly. We offer: - A starter kit with sensible defaults, - A VSCode extension which has AI that creates the internal tool for you, end to end, and, - A web app where you can deploy your tools. This gives you the best of both worlds -- everything you need to build tools just as fast as low-code, and an escape hatch when you need it.

malibou is a web application helping French SMBs to manage employees, run payroll and track compliance in a single app. When processing payroll in France, you either have the choice between an accountant with good advice but no way to connect an HRIS with him, or a good HRIS that does not include payroll services.
