Consumer Products Startups funded by Y Combinator (YC) 2026

We're building the open benchmark for commerce. Builders submit shopping agents. Independent validators run them against problems that change daily. The best agent earns the rewards, and every run becomes training data.

Egoist Machines is building infrastructure for a world where your personal context belongs to you, rather than to the apps and AI companies you use. Today, every assistant and consumer app builds its own version of you. We think that architecture is backwards. Your context should live with you, persist across products, and be available to any model, app or agent you choose. AI Passport is the first layer of that infrastructure. It brings the context you generate across AI assistants and everyday apps into one portable profile you control. Tell ChatGPT something and Claude can already know it, for example. Switch to a new product and it can understand you from the first interaction, without the new company needing to own the underlying data. Apps integrate through Sign in with AI Passport, requesting only the context they need for a specific purpose and duration. Users can see what is being accessed and revoke that access later. Underneath, we have built our own memory infrastructure for fast, compact per-user retrieval and permissioned access. We are distributing AI Passport directly to consumers through first-party products, while integrating it into consumer applications with existing distribution. Every new product that uses Passport gives users another reason to maintain their context there, and every additional Passport holder makes the context layer more useful to developers. The next step is to build a true Egoist Machine: an intelligent system whose memory, incentives and actions are governed by the individual it represents. We call it Digital Domovoy, the hardware extension of AI Passport. Instead of your most personal context ultimately living on somebody else's servers, it lives and is processed locally on hardware you control. AI Passport becomes the permission layer between that private local context and the cloud models and internet services you choose to use. Our North Star is the Egoist Machine: an intelligent system whose memory, incentives and actions are governed by the individual it represents.

MarkIt is an AI-powered regulatory compliance platform that helps consumer brands launch products in new markets. We review formulations, packaging, and supporting documents against local regulations, identify compliance gaps, and provide the exact changes, regulatory references, and market-ready labels needed before launch. We are initially focused on cosmetics and food products entering the U.S., replacing weeks of manual work across regulatory consultants, spreadsheets, and disconnected vendors with one actionable compliance workflow.

Stratify is the AI-powered user researcher that discovers the why behind every decision, click, and preference. Our platform uses agentic workflows that instantly recruit participants, conduct user interviews, analyze responses, and provide actionable insights.

ThirdLayer is the learning and alignment layer for enterprise AI. We continuously ingest and structure messy organizational context, complex operational processes, and siloed, permission-sensitive data, then grade agents against the outcomes each company cares about. Every interaction becomes feedback that helps agents improve over time. Companies use ThirdLayer to power their internal agents or embed it into the AI products they’re building. We give agents the context, evaluations, and learning loops they need to stay aligned with each organization and deliver better outcomes with every run.

Digital health holds a lot of potential but is ignoring a growing problem: diagnostic testing. Without this data, providers and organizations will be limited in the services they can provide patients at home. Scout has developed a platform - Hub, test kits, and app - that delivers health testing at home with 10x lower development cost and 3x lower per-test price. Our patented tech also meets performance requirements for medical diagnoses and integrates with the current healthcare tech stack. Scout’s technology is poised to disrupt the outdated $33Bn diagnostic market by democratizing testing while dramatically improving the patient experience. Scout has received $16M in non-dilutive funding from the NIH and other organizations to fully de-risk our platform, and our pipeline includes a diverse test menu for primary care (e.g. respiratory and sexual health), wellness (e.g. gut health), and chronic conditions (e.g. certain cancers). We have already received FDA authorization for our platform in clinical settings and are planning to launch our flagship Scout Hub in 2024.

Liv Labs (@livlabsfitness) is a US-based, Y Combinator-backed women's wellness innovator. Some 78 million American women live with pelvic floor weakness and 31M worry daily about leaking. Liv Labs now sells the patented Pippa® Resistance Spring to boost a healthy user's pelvic floor fitness during exercise, when it matters most. Pippa inventor, Carly Price, reimagined the humble pillow for Casper and has 45 patents to her name. Company CEO, Melody Roberts, incubated digital service experiences now scaling globally at McDonald's and Panera. Pippa development was substantially funded by non-dilutive SBIR grants from NIH, NSF, and State of Illinois, based on stellar product effectiveness data and user feedback like, "With this, surgery is off the table."

AesculaTech believes in building better lives through smart chemistry. We design custom smart materials for a range of biomedical, commercial, and industrial applications. Our platform technology, AesculaGel offers adaptive response to a wide range of stimuli and can be tailor-made for biocompatibility, material strength, and a range of other attributes. Founded by one of MIT's 35 under 35 Innovators, AesculaTech is the shared vision of scientists, engineers, and medical experts. Our cornerstone product, Humidifeye, is an ophthalmic platform to treat dry eye disease. Dry eye affects more than 25 million Americans and the global treatment market is projected higher than $6 Billion within the next decade. Our thermally responsive, form-fitting materials are suitable for sustained yet reversible occlusion across a range of treatment times. In contrast to existing technologies, our product will not extrude, or cause discomfort as it adapts to patients. Though Humidifeye is not yet FDA approved, expect to hear about it soon! In coordination with partners across several sectors, we have a variety of groundbreaking technologies in the works that live up to our vision. This work has already been recognized. AesculaTech was named a Rosenman Innovator, received a National Science Foundation I-Corps grant, was a finalist in the 2019 Octane High Tech Awards, and is a graduate of both the Y Combinator and TMCx accelerator programs. In short, Y-Combinator was only the beginning.
