Shor, a fintech startup in Y Combinator’s Summer 2025 batch, is betting that the next generation of global payroll will run on stablecoins and AI agents rather than on legacy banking rails. The company has launched what it calls an AI-native Employer-of-Record, aimed at giving remote teams a faster, cheaper, and fully compliant way to […]
Children’s entertainment is in an awkward moment. YouTube and Netflix produce more content than any kid could watch in a lifetime, but parents increasingly find it overstimulating, repetitive, and short on the kind of imaginative play that earlier generations took for granted. Pixley AI, a Y Combinator Fall 2025 startup, is betting that the answer […]
The first wave of AI-powered app builders fixed an obvious problem: shipping a usable frontend from a prompt. Tools like Lovable and v0 compressed hours of component tweaking into a few iterative descriptions, letting non-engineers and engineers alike move faster than ever on the user-facing layer. VibeFlow, a Y Combinator Summer 2025 company, is building […]
Loan servicing and collections has historically been one of the most labor-intensive – and most regulated – corners of consumer finance. Lenders need to recover delinquent balances, treat borrowers respectfully, and stay within an ever-tightening compliance perimeter, all while keeping the cost-to-collect manageable. Veritus, a Y Combinator Summer 2025 company based in San Francisco, is […]
Inside a private equity firm, the most numerate, sleep-deprived people in the building are usually the associates. They build leveraged buyout models, dissect confidential information memoranda, draft investment committee memos, update CRMs, and chase down the long tail of diligence questions that turn an idea into a deal. Zarna, a Y Combinator Fall 2025 startup […]
Drug development has long been hobbled by a quietly devastating problem: the same medicine that works for one patient can prove ineffective – or even toxic – for the next. Increasingly, the suspect is the trillions of microbes living inside us. Anto Biosciences, a Y Combinator Fall 2025 company, believes microbiome drug development can finally […]
For a generation of mechanical engineers, the everyday experience of CAD has been defined by a handful of incumbents – Solidworks, NX, Creo, Catia, Fusion 360, Onshape – and a strangely consistent set of complaints. The software is slow. Files take minutes (sometimes hours) to open. Design workflows are tedious, multi-step, and hostile to iteration. […]
Management consultants have long charged seven-figure fees to do one seemingly simple thing: talk to everyone in a company and figure out what’s broken. Ontora, a San Francisco-based startup in Y Combinator’s Spring 2026 batch, is betting that the whole exercise can be automated. The company has launched an AI operational intelligence platform that interviews […]
Food tracking apps have a retention problem. Calorie counters promise transformation but demand tedium, and most users churn within a few weeks. Paper Star, a San Francisco startup in Y Combinator’s Spring 2026 batch, thinks the category needs a rebuild – one that trades spreadsheets for stories. Its first product, Napkin Math, is an AI-powered […]
Ask any plant manager where the bottlenecks are and the answer rarely involves the factory floor itself. It is the paperwork around it – the RFQs that need processing, the quotes that need chasing, the suppliers that need reminding, and the production schedules that need rewiring every time reality intrudes. Korso, a Y Combinator Spring […]
Outbound sales has become an arms race of volume, and small teams are losing. Cold lists, mass sequences, and blanket personalization tools have driven reply rates to historic lows while inboxes become harder to crack. Gojiberry AI, a Y Combinator Spring 2026 company, is pitching a different approach: an AI outbound sales platform with a […]
Developer documentation has always been the quiet infrastructure of software. It determines which APIs get adopted, which SDKs get abandoned, and which products get replaced. Manicule, a Y Combinator Spring 2026 startup, believes that infrastructure is overdue for a rebuild – and that the rebuild looks more like an AI-native studio than a freelance writing […]
