Eric Wei is the cofounder and co-CEO of Karat Financial, the Los Angeles fintech building banking, credit, and tax tools for full-time content creators. A Harvard economics grad who passed through Blackstone, McKinsey, and a product role on Instagram Live, Wei left big tech to build the bank that creators - who often earn six and seven figures yet get rejected by traditional underwriters - couldn't get anywhere else. Karat's flagship Black Card approves applicants on income and audience metrics rather than FICO scores. The company has raised over $100 million from SignalFire, Union Square Ventures, GGV, Y Combinator, Visa, and a roster of top creators, and partners with Visa to issue cards.
Eunjoon (EJ) Cho is the co-founder and CEO of Tofu, a San Mateo AI platform that automates personalized, multichannel B2B marketing at scale. A Stanford PhD who trained speech-recognition neural networks at Google and worked at Meta, Affirm and Fast, Cho spent years mapping the generative-AI landscape before ChatGPT opened the door. He started Tofu with Honglei Liu and Elaine Zelby in 2023, raised about $17M from SignalFire, Index Ventures and HubSpot Ventures, and grew revenue 12x in roughly a year by replacing the bloated stack of point tools marketers juggle with one platform that ships finished assets.
Joshua Reischer is a board-certified internal medicine physician who walked out of the exam room to rebuild the most tedious part of a doctor's day. As CEO and founder of Health Note, he turned the pre-visit patient questionnaire into AI-generated clinical notes that drop straight into the chart, cutting documentation and intake time before the appointment even starts. Health Note now runs across clinics nationwide, processes millions of patient visits a year, and raised a $17M Series A led by SignalFire with backing from Cedars-Sinai, Northwell and UnityPoint Health.
Sam Schwager is the co-founder and CEO of SuperDial, a San Francisco voice-AI company that automates the high-volume phone calls between healthcare billing teams and insurance payers. A Stanford computer scientist and former McKinsey consultant, he started the company with college classmate Harrison Caruthers after a personal run-in with out-of-network insurance reimbursement turned into a business. SuperDial raised a $15M Series A led by SignalFire in June 2025 and is taking aim at the roughly $1 trillion the US spends each year on healthcare admin.
Samir Dutta is the co-founder and CEO of Farsight, a New York AI company that automates the grunt work of high finance - pitch decks, valuation models, CIMs and buyer lists - directly inside Excel and PowerPoint. An MIT graduate who did time at Evercore and General Atlantic before building the tool he wished he'd had, Dutta raised a $16M Series A led by SignalFire in 2025 and landed on the Forbes 30 Under 30 list in the AI category for 2026.

Nichole Garcia is Co-Founder and President of OrthoFX, the doctor-delivered clear aligner startup she built with two former Invisalign executives. With a BS in Biochemistry from UCLA, an MBA from Pepperdine, and a diploma from Oxford, she spent two decades running global divisions at Philips Oral Care and Align Technology before co-founding OrthoFX in 2017. The company raised $17M total - including a $13M Series A led by SignalFire in 2020 - to commercialize a proprietary FXTetra polymer that delivers 50% faster treatment, paired with an AI-powered remote monitoring platform called FXOnTrack.
Wayne Hu is a General Partner at SignalFire, the AI-native venture capital firm he helped build from its first investment team in 2015. A Princeton-trained mathematician turned Google strategist turned VC, he led the YouTube ads monetization operation at Google before pivoting to investing — backing companies like Grow Therapy, EvenUp, and Solace from the earliest stages. His edge is equal parts pattern recognition and proprietary data: SignalFire's Beacon AI platform ingests signals about talent, market trends, and founder trajectories that most investors never see. He invests where incumbents haven't bothered — sectors ripe for end-to-end reinvention.
