Thomas Rivas
Thomas Rivas is the founder and CEO of Vendoo, a software platform that helps online resellers list and manage inventory across marketplaces like eBay, Poshmark, Etsy, Mercari and Facebook. He started selling online as a high schooler in 2007, kept selling through college at the University of Maryland, and turned the tedium of posting the same item to a dozen sites into a company that went through Y Combinator's Winter 2022 batch. Vendoo has grown to roughly 50-60 employees, reached profitability, and has been used to create tens of millions of listings.
Tim Hyer
Tim Hyer is the co-founder and CEO of Trusty (YC W22), a private marketplace and agent-to-agent matchmaking network for off-market real estate. A Duke-trained designer who has bought homes eight times, Hyer built Trusty to bring transparency and real conversation to what he calls the largest financial purchase of most people's lives - creating a place to find, discuss, and transact on homes whether or not they are formally listed.
Yih Lin Teh
Yih Lin Teh is the co-founder and CEO of Axross (YC W22), a Singapore-based startup building AI-driven autonomous HVAC control systems that cut energy use and operating costs for factories and semiconductor plants across Southeast Asia. An econometrician turned climate tech entrepreneur with roots at LSE and MIT and stints across three continents, Teh returned to ASEAN to make the region's manufacturing sector greener and more competitive.
Ythalo Silva
Ythalo Silva is the co-founder and CEO of Vobi, a Y Combinator-backed (W22) project and construction management platform built for small construction businesses across Latin America. He turned a struggling home-renovation marketplace called HomeHero into a SaaS product that helps contractors, architects, and remodelers cut manual budgeting and procurement work in half. A serial founder out of the MAR Ventures venture builder, he previously co-founded Modiax, acquired by Foxbit in 2019.
Tullie Murrell
Tullie Murrell is the CEO and co-founder of Shaped, a New York startup building a real-time retrieval engine for search, feeds, and agents. Before Shaped, Murrell spent about five years at Facebook AI Research, where he created PyTorchVideo, the leading open-source library for video understanding, and was an early core contributor to PyTorch Lightning, a training framework now used by millions of developers. The video models he led powered Facebook newsfeed ranking and Instagram Reels. In 2021 he left big-tech research to package that same personalization machinery into a self-serve product for companies without armies of ML engineers. Shaped went through Y Combinator's W22 batch and raised an $8M Series A led by Madrona Ventures in July 2024.
Jennifer Liu
Jennifer Liu is the cofounder and CEO of Toko, an AI English tutor that got its start when a pandemic-era hack called GPT 奶奶 (an AI grandma built to help her practice Mandarin) revealed a far bigger hunger for spoken English across East Asia. An MIT computer science grad and early Quizlet engineer-turned-PM, Liu turned that side project into a Y Combinator (W22) company that now ranks among the top education apps in Taiwan, Hong Kong, Vietnam and Thailand, with 4.9 stars from 20,000-plus reviewers.
Jon O'Bryan
Jon O'Bryan is the CEO and Co-founder of Atlas (YC W22), an AI-first customer support platform built to replace legacy tools like Zendesk and Intercom. A PhD physicist turned serial entrepreneur, Jon previously co-founded PadSplit - a co-living marketplace that housed 23,000 people across 18 U.S. cities - and Blanket Homes. At Atlas, he is on a mission to transform customer support from a cost center into a revenue driver, bringing together session recording, omnichannel ticketing, AI copilot, and customer timeline tools in a single ergonomic platform backed by Y Combinator and angel investors including Parker Conrad (Rippling), Jack Altman (Lattice), and Arash Ferdowsi (Dropbox).
Nahuel Candia
Nahuel Candia is the co-founder and CEO of Rebill, a payments-infrastructure company that lets global businesses process payments, payouts and financial operations across Latin America and the US without setting up local entities. A developer since age 14 who built three companies before 30, he took Rebill through Y Combinator's Winter 2022 batch and raised roughly $3.6-3.7M from Tiger Global, SV Angel, SOMA Capital, Magma Partners and founders like Vercel's Guillermo Rauch and Dropbox's Arash Ferdowsi. He says Rebill was rejected by YC dozens of times before getting in, and that persistence is now part of the company's origin story.
Erin Tavgac
Erin Tavgac is the co-founder and CEO of Redbird, a New York based AI-powered analytics platform that lets non-technical employees run the full analytics pipeline - data prep, wrangling, analysis, reporting and data science - through natural language instead of code. A Stanford-trained ex-McKinsey consultant who spent a decade building data and consumer-insights practices, Tavgac launched the company (originally Cube Analytics) with brother Deren Tavgac, took it through Y Combinator's Winter 2022 batch, and raised a $7.6M oversubscribed seed led by B Capital. By 2024 Redbird had reframed itself around conversational AI agents and counted eight Fortune 50 brands among its customers.
Ibby Syed
Ibby Syed is the founder and CEO of Cotera, a New York-based Y Combinator (W22) startup building an agentic AI platform that lets enterprise teams spin up AI agents on top of their own data warehouses. Peloton's first data science hire and a Harvard applied math graduate, he co-founded Cotera with Tom Firth, survived a long stint stuck in the 'consulting trap,' and pivoted the company from a churn-analytics dashboard into a prompt-based AI agent builder now serving customers like Bilt, OpenSea, Skims and Coterie at roughly $1M ARR.
Isaac Eaves
Isaac Eaves is the co-founder and CEO of Joon, a San Francisco startup that turns kids' real-life chores and routines into a video game they actually want to play. A UC Berkeley computer science and business grad who ran profitable Minecraft servers as a teenager and worked in product at Workday, he took Joon through Y Combinator's Winter 2022 batch. His pitch is simple: he spent 10,000 hours gaming as a kid, so he knows exactly what keeps a child glued to a screen - and he is bending that same pull toward homework, bedtime, and brushing teeth.
Nelson Jones
Nelson Jones is the co-founder and CEO of Kular, a London-based AI lead generation platform that only charges customers when it delivers actual sales leads. An Oxford law graduate who started building businesses before he finished his degree, Nelson moved from legal-sector sales at Luminance into Entrepreneur First, where he met co-founder Saaras Mehan in the LD16 cohort. The pair launched in 2021, went through Y Combinator's Winter 2022 batch, and pivoted from an AI business-development tool for law firms into Kular, which today generates leads for over 1,000 companies via email, LinkedIn, and AI voice notes. Kular's signature bet is radical alignment: pay only for results.
Rakesh Goyal
Rakesh Goyal is the co-founder and CEO of Velt, a Y Combinator (W22) startup building the collaboration layer for the internet. Velt ships a full-stack SDK that lets product teams drop contextual comments, notifications, presence, huddles, async recordings and CRDT-based multiplayer editing into their apps in days instead of months. Before Velt he spent roughly nine years as a product manager at Google, where he helped launch augmented reality in Google Maps and Search and worked across Payments, Access and the Next Billion Users initiative. He frames Velt's ambition simply: what Okta is to auth and Algolia is to search, Velt wants to be to collaboration.
Rani Mavram
Rani Mavram is the co-founder and CEO of Complete, a San Francisco compensation platform that turns the awkward salary conversation into an interactive offer letter. A UC Berkeley dual-degree grad and former Google product manager, she launched Complete through Y Combinator's Winter 2022 batch, raised a $4M seed led by Accel, and was named to the Forbes 30 Under 30 list for enterprise technology. Her pitch is simple: every company should know what it means to pay people, and no candidate should have to guess.
Sammy Sidhu
Sammy Sidhu is the co-founder and CEO of Eventual, the company behind Daft, an open-source, Python-native data engine built to wrangle messy multimodal data like images, video, audio and LiDAR at petabyte scale. A UC Berkeley EECS grad with a background in high-performance computing and deep learning, he cut his teeth on Wall Street high-frequency trading and then on the perception stacks of self-driving cars at DeepScale (acquired by Tesla), Lyft Level 5 and Woven Planet (Toyota). After repeatedly watching brilliant engineers burn 80% of their time fighting data plumbing instead of building, he and Jay Chia turned that frustration into Eventual. Daft now processes petabytes daily at Amazon, CloudKitchens, Together AI and Essential AI, and the company has raised roughly $30M from investors including CRV, Felicis, Microsoft's M12 and Citi.
Sean Doherty
Sean Doherty is the co-founder and CEO of GovDash, a New York-based AI platform that helps companies win and run U.S. government contracts. What started as a college friendship and a hangout-scheduling app turned into a Y Combinator (W22) company now serving nearly 200 contractors whose customers booked over $5B in awards in a single year. In January 2026 GovDash raised an oversubscribed $30M Series B, bringing total funding to roughly $40M, as Doherty pushes to automate the entire government-contracting lifecycle from opportunity discovery to post-award delivery.
