Conor Murray is the cofounder and CEO of OpenInvest, the values-based investing platform acquired by J.P. Morgan in 2021. An MIT-trained mathematician and computer scientist, he built portfolio-optimization technology at Bridgewater Associates managing more than $150 billion before starting OpenInvest in 2015 to let everyday investors align their money with their ethics. He now guides ESG innovation inside J.P. Morgan Wealth Management.
David Roger is the cofounder and CEO of Hetal Retail, a New York-based startup that uses computer vision and a crowd of everyday shoppers to tell brands what is really happening on store shelves. Before Hetal, he co-founded and ran Felix Gray, the company that pushed blue light glasses into the mainstream and onto the shelves of Target, CVS and Best Buy before selling in 2023. A self-described generalist who lives at the intersection of analytical and creative, Roger turned the frustrations he felt as a brand operator - expensive, slow, unusable retail data - into the company he runs today.
Dylan Keil is the co-founder and CEO of Bearing AI, a Palo Alto startup that uses artificial intelligence to cut carbon emissions and improve operations across the global maritime shipping fleet. A Stanford-trained mechanical engineer who grew up on college campuses, he built and sold the mobile sensor startup Chronos to Life360 before launching Bearing in 2019. Backed by Andrew Ng's AI Fund and Japanese shipping giant Mitsui & Co., Bearing predicts vessel fuel consumption, speed and carbon ratings without onboard sensors, helping shipowners navigate regulations like CII, EU ETS and FuelEU Maritime while saving fuel and money.
Max Spero is the cofounder and CEO of Pangram Labs, a New York based startup building the most accurate AI-text detector on the market. A Stanford-trained machine learning engineer who worked at Google, Two Sigma, Yelp, and the self-driving company Nuro, Spero co-founded Pangram in 2023 with college dormmate Bradley Emi to draw a clean line between human and machine writing. His obsession is the false positive rate: he refused to ship at one wrong call in a hundred and pushed his team to one in ten thousand. Pangram now powers AI verification for journalism platforms, schools, and trust and safety teams, and raised about $4M in seed funding in 2025.
Moe Nada is the CEO and cofounder of SupportFinity, a San Francisco AI-native recruitment automation platform that sources across more than 2.1 billion profiles and runs the full hiring lifecycle through proprietary AI agents. A UC Berkeley MBA with roughly two decades across HP, HPE, IBM and OpenText, he moved from software engineering into product, implementation and customer success before betting that the resume-screening grind belongs to machines and judgment belongs to people.
Nikhil Rao is the cofounder and CEO of Reflex (formerly Pynecone), an open-source framework that lets developers build full-stack web apps in pure Python without touching JavaScript or React. A UC Berkeley EECS graduate who worked at VMware, Drive.ai, and Apple, he founded Reflex in 2022 with college roommate Alek Petuskey after watching brilliant ML engineers struggle to ship simple user interfaces. Reflex went through Y Combinator's W23 batch, raised a $5M seed led by Lux Capital, and has grown into an enterprise platform used for internal tools across roughly 30% of the Fortune 500.
Amanda Rees is the co-founder and CEO of Bold, a Los Angeles based digital fitness platform that delivers personalized, science-based exercise programs to help older adults build strength, ease pain, and prevent falls. A Princeton-trained chemical and biological engineer who is also a longtime dance and tai chi instructor, Rees built Bold after spending most of her twenties caring for her grandmother and discovering how few preventive tools existed for aging well. Bold partners with Medicare Advantage plans and has raised about $27 million in total funding, including a $17 million Series A.
Andy Thompson is the cofounder and CEO of Safehub, a San Francisco company that puts low-cost sensors on buildings to deliver real-time, building-specific earthquake damage data. A structural and earthquake engineer trained at UC Berkeley, he spent 16 years at the global engineering firm Arup, where he built its Catastrophe Risk & Insurance practice and worked post-disaster in countries from Chile to Haiti to Japan. He cofounded Safehub in 2015 with catastrophe-risk veteran Doug Frazier, raised a $9M Series A in 2021, and has deployed sensors across thousands of buildings in dozens of countries, now powering sensor-triggered parametric earthquake insurance with partners like Liberty Mutual Reinsurance.
Bing Li is the CEO and co-founder of Intalight, an ophthalmic imaging company behind the DREAM OCT swept-source platform. Founded in 2014 by a group of scientists and Silicon Valley industry veterans, Intalight built one of the first swept-source OCT devices in 2019 and has since powered more than 170 peer-reviewed retinal-imaging studies. Trained as an engineer and applied mathematician, Li moved from the auto and semiconductor industries into eye care, betting that faster, deeper, wider retinal scans would change how clinicians see inside the eye. In May 2025 the company won CE Mark clearance to sell DREAM OCT across the European Union, with FDA review pending in the United States.
Brian Jeong is the CEO and cofounder of Hawthorne, a New York personalized men's personal care brand he launched in 2016 with his childhood best friend Phil Wong. Hawthorne built its business on a data-driven quiz that matches men to fragrances, skincare, hair care and grooming products tuned to their body chemistry and preferences. With no prior beauty experience, Jeong reverse-engineered the fragrance world through roughly 100 industry interviews in three weeks, growing Hawthorne from an online storefront into a Series B company stocked in thousands of retail doors, including the vast majority of Target stores.
Kevin Stein is the CEO and cofounder of Delos Insurance Solutions, a San Francisco insurtech MGA that writes homeowners insurance for wildfire-exposed California properties that mainstream carriers refuse. A Bay Area native and aerospace engineer who once sold satellites at SSL/Maxar, Stein co-founded Delos in 2017 with Shanna McIntyre to apply satellite imagery, geospatial AI, and wildfire science to a problem the rest of the market treats as uninsurable. Delos accepts roughly two-thirds of the homes the standard market declines, and Stein reports it has never insured a home that later burned. He moonlights as a bassist and songwriter.
Swamy Vijayan is the CEO and cofounder of Zafrens, a San Diego biotech reinventing drug discovery by shrinking a 96-well plate down to 200,000 microwells that image and sequence single cells at once. A physicist by training who admits he was driven less by a love of biology than by dissatisfaction with theoretical physics, he is a serial founder whose previous company Omniome sold to Pacific Biosciences for up to $800 million. His stated goal is not a quick exit but a foundation for smart people to do important things for the next 100 years.
Alfredo Brillembourg is the cofounder and CEO of Meadow, a New York fintech rebuilding how American students pay for college. After a missed tuition deadline locked him out of registration as an undergraduate, he traded a finance track that ran through Goldman Sachs, Bowery Capital, and NEA for the unglamorous plumbing of campus billing. Meadow now serves over 170 colleges and universities, has delivered nearly a million net-price estimates, and raised a $14M Series A led by Matrix Partners in 2025.
Abel Mengistu is the cofounder and CEO of FlutterFlow, the low-code visual app builder that has enabled over 2 million users to create production-ready Flutter applications without deep coding expertise. A former Google senior software engineer who worked on Google Maps and ATAP hardware, he co-founded FlutterFlow in 2020 with Alex Greaves after a failed restaurant-recommendation startup taught them the real bottleneck was app development complexity. Accepted into Y Combinator's Winter 2021 batch after applying past the deadline, they famously survived 'No-sleep November' to build FlutterFlow 1.0 in a single month. The company raised a $25.5M Series A from GV (Google Ventures) in January 2024, has grown to 173 employees, and in 2025 launched Dreamflow - an AI-powered builder that generates production-ready app screens in roughly 10 seconds.
Adi Goel is co-founder and COO of Sardine, an AI-powered fraud and compliance platform that has screened over $1.36 trillion in payments for 300+ enterprise customers across 70+ countries. Before Sardine, he scaled Revolut's entire US business from zero to millions of customers and led product strategy at Deutsche Börse managing a $200M fintech fund. A Wharton MBA and IIT Delhi engineer, Goel brings rare cross-disciplinary range across quantitative finance, product, and operations to building fintech infrastructure.
Andy Ruff is the co-founder and Chief Product & Tech officer at Numa, an AI communication platform purpose-built for automotive dealerships.

Greg Sullivan is the CEO and cofounder of AFAR, the award-winning travel media brand he launched in 2009 with Joe Diaz after a transformative six-week trip to India. A former corporate securities attorney, investment banker, and serial entrepreneur — he previously co-founded the world's largest-selling coin-operated basketball game manufacturer and served as President and CEO of DriveTime Automotive Group — Sullivan reinvented himself in his 40s through philosophy studies at Cambridge and a late-discovered passion for international travel. Under his leadership, AFAR has grown from a print magazine into a multiplatform media brand with a digital presence, a podcast, a nonprofit foundation (Learning AFAR), and a B Corp certification, and in 2025 expanded to Europe with the acquisition of SUITCASE Magazine.
