Steven Wang is the founder and CEO of dub, a regulated, SEC-registered copy-trading app that lets everyday investors mirror the portfolios of vetted managers, hedge funds, and members of Congress with one tap.

The company has crossed 1 million downloads and raised about $47 million, including a $30M Series A in May 2025.

Harper (YC W25) is an AI-native commercial insurance brokerage that turns the $100B+ industry of email and spreadsheets into a fully autonomous engine for Main Street America. Co-founded by Dakotah Rice and Tushar Nair — two Goldman Sachs alumni who swore they'd never work in insurance — Harper uses its internal AI platform, Harper Hub, to automate form completion, carrier matching across 160+ carriers, underwriter follow-ups, and client communications. The result: 1–2 day quotes instead of 5–7, 85% success rate on traditionally 'uninsurable' cases, 5,000+ businesses covered across 35 states, and 1,000+ customers handled per month versus 20–30 for a typical human brokerage. Backed by $54M in total funding led by Emergence Capital, Peak XV, and Y Combinator. Named after Dakotah's mother's maiden name.
