Superme

SuperMe (legal name Super Me Network, Inc.) is a San Francisco-based AI startup building what it calls the 'AI-native professional network.' The core idea: professionals connect their content -- writing, talks, podcast appearances, notes, and even private artifacts like Google Docs or Granola meeting notes -- and SuperMe trains a multimodal AI 'profile' that can converse on their behalf in their own voice. Other users can ask that profile questions directly, or use SuperMe's 'Perspective Search' to route a business question to the most relevant expert profiles across the network and compare answers -- as the founders put it, 'how advice actually works in the real world.' The company was incorporated in Delaware in 2024 and is headquartered at 140 New Montgomery Street, San Francisco (per SEC filings; earlier filings list 1395 22nd Street #535, San Francisco).

Founders: CEO Casey Winters and CTO Ludo Antonov (full legal name Lyudmil Antonov, per SEC Form D) met while working together on Pinterest's growth team, where Winters led growth product and Antonov led growth engineering during Pinterest's shift from social-driven to SEO-driven, international growth ahead of its 2019 IPO. Winters' career path: intern/early growth-marketing hire at Apartments.com and sister site Homefinder.com; early marketing hire at GrubHub, where he helped scale the company from 3 cities and a $1M Series A to 1,000+ cities and a $7.3B IPO exit; Pinterest growth product lead; then an independent advisor to companies including Airbnb, Canva, Discord, Figma, Tinder, Faire, and Whatnot, plus 'a stint' working out of Greylock's offices; and Chief Product Officer at Eventbrite (leading product, design, research and growth marketing, including navigating Eventbrite through the COVID-19 pandemic). He is also a well-known essayist on growth/product topics via his newsletter 'Casey Accidental' (Substack) and has been affiliated with Reforge. Antonov, who is from Bulgaria, was previously a software engineer at Microsoft and Hulu, led Pinterest's growth engineering team, then led engineering teams at Lyft, and most recently was Head of Engineering at resale/livestream shopping unicorn Whatnot -- where he and Winters (then advising Whatnot) reconnected and decided to build an AI company together. Both founders have said they intentionally came from outside the traditional Stanford/VC pipeline ('Ludo came from Bulgaria, and I came from New Orleans,' Winters told Upstarts Media), and that experience mentoring underrepresented founders shaped their interest in democratizing access to elite professional networks and expertise via AI.

Funding: SuperMe raised a $6.8 million Seed round led by Mike Duboe, a Venture Partner at Greylock, with what the company's launch coverage described as 'a bunch of product leaders participating personally,' including Superhuman CEO Shishir Mehrotra and Shopify executive Archie Abrams. Greylock's own portfolio page also lists Mike Duboe as the deal lead, and a Crunchbase profile additionally lists Karman Ventures as an investor (unconfirmed via primary sources beyond Crunchbase). SEC Form D records (filed 2024-12-10, CIK 0002047805) show: incorporation year 2024; a first sale of securities on 2024-11-25; a total offering amount of $6,799,999; $4,499,993 sold and $2,300,006 remaining as of the filing date; and 4 investors at that point -- consistent with the round having closed over roughly a year, from a Greylock Edge-incubation close in late 2024 through to the round's public unveiling and (presumably) final close around the company's public launch in November 2025. The Form D lists Casey Winters (Executive Officer/Director/Promoter) and Lyudmil ('Ludo') Antonov (Director/Promoter) as the only related persons, and was signed by Winters as CEO. No further funding rounds (e.g., Series A) have been publicly reported as of this research. Valuation has not been publicly disclosed.

Business model

Consumer/professional AI social network ("expert network"): professionals connect writing, talks, notes and other artifacts (including private docs like Google Docs and Granola notes) to train a multimodal AI 'profile' of themselves; other users converse with these AI profiles and with a cross-profile 'Perspective Search' engine to get expert-grounded answers.

Not yet monetizing as of the Nov 2025 public launch. Planned model is tiered subscriptions to engage more deeply with an expert's AI profile, with revenue shared between the expert and SuperMe; longer-term plans include offering 'agentic' versions of experts that businesses can embed into their own data/systems (e.g., via Slack).
