    Harbor
    Y Combinator LogoP2026
    Active • 2 employees • San Diego, CA, USA
    Harbor is a new, AI-enabled system of record for clinical trial data that replaces legacy electronic data capture (EDC) systems. Today, medical device and pharma companies spend months setting up custom EDCs that research sites then spend hours per subject per day entering data into. With Harbor, the EDC is spun up simply by reading your clinical trial protocol and research sites upload raw source documents into the platform, skipping the tedious and error-prone data entry process altogether. EDCs haven’t fundamentally changed since the 1990s. They are passive, regulatory compliant data bins that cause massive trial delays, coordinator burnout, and weeks of back-and-forth to resolve data errors. Because of this, data management currently consumes ~30% of total clinical trial budgets. With LLM and document extraction capabilities finally reaching the accuracy, reliability, and traceability required in high-risk domains, Harbor is redefining the way data is collected and monitored in clinical trials, all while remaining fully GCP- and 21 CFR Part 11 compliant. After months of building our initial product, our platform is now live with its first few clinical studies. For our largest customer and their 1600 subject randomized trial, we were able to use our internal tools to get their study database configured in just one week, which was ten times faster than legacy EDC vendors quoted. We built Harbor because we lived through this problem. Albert spent four years in clinical trials and regulatory strategy for a medical device startup, spending weeks at clinical sites watching coordinators battle legacy software firsthand. Nate brings the technical firepower, having built scalable software at Google and Ramp and as employee #1 at a previous YC startup.

    10x Science develops frontier AI models with deep memory to redefine how scientists understand and engineer biology across the life sciences, starting with drug development. AI-powered drug discovery is flooding the pipeline with new candidates faster than ever. But before any of them can advance to the clinic, scientists must deeply characterize the protein therapeutic to understand whether it will work. Today, that process takes months of manual, error-prone analysis that cannot keep pace with discovery. Our AI-native platform automates it, giving drug developers the confidence to advance the right candidates and stop the wrong ones early. We have strong commercial traction with enterprise pharma customers. Our founding team built the field of next-generation protein characterization out of Carolyn Bertozzi's Nobel laureate lab at Stanford. Collectively, we have 18+ years of collective domain expertise, 47+ scientific publications, and a 2x YC Founder. We move at the highest velocity and are positioned to lead the next generation of modern AI development in the life sciences.

    Y Combinator LogoF2025
    Active • 5 employees • San Mateo, CA, USA
    Moss is building the real-time semantic search runtime for conversational and multimodal AI. Our system enables voice agents, copilots, and chat interfaces to retrieve, reason, and respond in sub-10 ms, delivering the responsiveness that makes AI interactions feel truly natural. If you’ve ever built a conversational or voice AI product, you’ve felt the lag. That moment when an agent pauses and the illusion of intelligence breaks. The bottleneck is almost always retrieval. Each query hops across networks and databases, adding delay and cost. Moss eliminates that gap by keeping retrieval close to where the agent runs. Moss runs natively across browsers, mobile devices, and servers with an optimized vector index built in Rust and WebAssembly. It enables teams to build AI products that feel instant, contextual, and adaptive. The experiences that sustain engagement and unlock new kinds of interaction. For our customers, this translates into tangible business value: stronger user retention, higher conversion, and entirely new product categories made possible by real-time understanding. Moss is already powering production pilots across voice AI and developer platforms, achieving sub-10 ms retrieval and 70–90% token savings compared to traditional pipelines.

We let organizations instantly find any object, behavior or event, in any footage, without needing to train a model or collect any training data. The Pain: Creating vision models usually takes months: collecting training data, training, then deployment. Worse yet: + it’s often impossible to get enough data for a specific task, and + even the best cv models struggle to generalize across diverse camera setups, workflows and environments. To overcome these blockers, we bet early on the power of VLMs and built a vision engine that can generalize across any task and doesn’t need any training data. We published a NeurIPS workshop paper showing our new methods with VLMs beat traditional CV even at niche tasks.

    Frizzle uses AI to grade handwritten math assignments for teachers and transform them into rich analytics and differentiated assessment to help personalize instruction for every student. Teachers spend over 10 hours a week or 25% of all their work grading - Frizzle does it in minutes. Frizzle is the most valuable piece of software for teachers ever, as it eliminates the most time-consuming part of their workflow so they can focus on teaching. Frizzle shifts education from waterfall to agile learning. Instead of waiting for end-of-unit tests to discover gaps, teachers get continuous, real-time insight into student thinking from everyday work. Feedback becomes immediate, instruction adapts weekly, and learning iterates (measure, adjust, improve) so every student progresses faster with less teacher burnout. Frizzle was named an official White House AI Education Partner alongside OpenAI and Meta: https://www.whitehouse.gov/edai/. Frizzle was co-founded by Abhay Gupta and Shyam Sai, who met in high school over 10 years ago.

    When enterprise agents fail in production, the conditions that caused the failure are critical: user state, data, tool calls, and context. Without a way to recreate these conditions, teams can't fix what broke. Playgent provides infrastructure to create high-fidelity sandbox environments for AI agents. Our environments come packaged as a single MCP url where tool calls are mocked, authentication is abstracted away, and test data can be initialized via natural language or JSON specifications. Teams can use Playgent to reproduce production failures in safe, scoped environments that accurately reconstruct state. Finally, export runs as OTel traces from Playgent's environment to plug directly into your observability tools or RL pipelines.

    We use AI to help electrical contractors submit more competitive bids to construction projects. We do this by speeding up the estimating part of bidding, which is the most tedious part of the job. Specifically, we're building models that can understand floor plans and count electrical devices to generate the estimate. Bidflow is the future of electrical pre-construction.

    Epicenter is an ecosystem of open-source, local-first apps that share a memory. We store all your work—notes, transcripts, chat histories—in a single folder of plain text and SQLite. Every tool we build shares this memory: your text editor, personal assistant, etc.. It's open, tweakable, and yours. Grep it, open it in Obsidian, host it wherever you like. The choice is yours. Our vision is to build a personal workspace where you own your data, choose your own AI models, and replace siloed apps with open, interoperable alternatives. All while preserving authenticity and being free and open source. ❤️

    Floot lets non-coders & entrepreneurs build real web apps that actually work. We’re taking a new approach by building everything from the ground up for AI. ✨ Try building an app at floot.com Existing AI app builders fall short of enabling non-coders to build real, serious apps. They often: - Break down when building anything more than a prototype or toy app - Have non-coders stuck with errors they don’t understand - Require non-coders to handle multiple services designed for developers (e.g. for backend, database, hosting, etc) The fundamental problem: these AI app builders just cobble together existing developer tools and slap AI on top, but these tools were designed for humans and not for AI. The result? Non-coders get excited, start building, hit a wall, and then abandon their projects. Floot is purpose-built for AI. Our secret sauce: 1) Instead of reusing a coding framework designed for humans, we created a specialized framework that dictates how AI should write code and how the code runs on our infrastructure. This allows us to enforce best practices, detect errors earlier, and give the best feedback to the AI. As a result, Floot can write better code and fix issues more effectively. 2) Floot has the entire tech stack built-in (backend, database, hosting, etc) so building and managing an app feels seamless, especially for non-coders. And because we control every layer of the stack, we can optimize each layer for AI-first coding. Because of this, non-coders can get more done with less time and prompting. They can finally build serious apps that work, instead of getting stuck in frustrating error loops and then abandoning their projects. We also built a highly scalable hosting system directly on AWS so Floot apps can handle real traffic and business demands. This means non-coders can build, deploy, and scale their apps on a single platform seamlessly. Plus, Floot is really fun to use! Try building an app at floot.com

    Locata is an AI referral management platform for Primary Care. We deploy AI agents to automate every step of the referral process that back-office staff face daily, from submitting prior authorizations to broadcasting updates and following up with patients. This frees up staff to focus on patient care. Primary care back-offices are severely understaffed and overburdened by administrative work associated with referrals. Additionally, patients suffer navigating the complex referral process, which can have disastrous health effects if they don’t get the care they need. These factors point to a glaring gap in the system—where out of over 100 million specialist referrals issued annually in the US, only half are actually completed. Locata is tackling this problem head-on, saving administrative staff hours each week and ensuring that the referral process goes as smoothly as possible for patients and their providers. Alejandro and Josh met at Stanford where they graduated with BS degrees in Computer Science. Alejandro was a senior software engineer at Meta’s Reality Labs where he led development of several AI features for wearable products and prior to that conducted AI research at Stanford Medicine. Josh graduated with a masters in Computer Science, specializing in AI, before working as a software engineer at Google where he developed AI products that served over 1 billion users. Within two weeks of building our product, we signed a major regional health center and have saved them over 100 hours of work in our first month live.

    Certus AI is replacing the restaurant phone line with Voice AI. Restaurants lose up to $100,000 per year per location from missed calls, lost orders, and abandoned hold lines. Staff are overwhelmed. IVRs frustrate customers. Call centers are expensive and impersonal. It’s 2025. Guests don’t leave voicemails or wait on hold. They just move on. Certus is an AI voice agent built for restaurants. It answers every call, 24/7 — taking orders, processing deliveries, booking reservations, upselling, and handling complaints in English, Spanish, French and more. Certus is built to manage the phone line end to end, from the customer call to the restaurant tech stack, with zero human intervention required. It currently integrates with industry-leading systems like Toast, Square, Clover, UberEats, DoorDash, and more. We’re building the voice layer of the modern restaurant — the employee they’ll never fire. We started Certus because we lived the pain. Gurveer (CEO) grew up answering phones in his family’s restaurant and helped operate them, growing from 1 to 11 locations in 7 years. Later, he and Adam (CRO) ran a restaurant growth startup to help others increase revenue, but kept watching clients bleed cash because no one picked up the phone. So we built the solution the industry always wished existed. Until now, this problem was considered unsolvable. But Voice AI has finally crossed the conversational chasm and 72% of consumers now prefer AI over humans as long as it means faster and better service. More importantly, the market is begging for this. The North American restaurant industry crossed $1 trillion in 2024, and it's projected to hit $1.5 trillion in 2025. Yet over $100 billion is still lost annually to missed calls, human error, and outdated tech. As the market continues to grow, so do the losses! Our customers say it best: - “Certus changed my life overnight.” - “We were losing the ability to give great in-house service — the phone was killing us.” - “70% of my business comes through the phone. That’s mine and my 16 staffs livelihood.” - “Before Certus, I used to lose 40 - 60 calls a day…. now my printer just stays printing!” - “I’ve been in the business 38 years. I’ve been waiting for this since then.” Certus is here to fix the $120B phone problem — one call at a time. And in doing so, we’re redefining how the restaurant industry communicates forever, starting with the phone line.
