Public-source profile · as of Oct 2026
蔡文胜 · also known as Mike Cai
Entrepreneur and well-known angel investor in China’s internet and technology sector. Founder and substantial shareholder of Meitu; founder and chairman of Longling Capital; chairman / non-executive director of Hong Kong–listed CAI Corp (00080) and Long Corp (2312); non-official member of the HKSAR Task Force on Promoting Web3 Development.
About
Public narratives describe a grassroots internet path: domains and webmaster communities, the sale of 265.com to Google, a shift into angel investing, and capital-markets visibility via Meitu and other bets. In recent years, capital and physical footprint have concentrated in Hong Kong, with a focus on AI and Web3 / digital assets.
Meitu-related HKEX disclosures state that he completed junior high education at Shi Guang High School in Shishi, Fujian (July 1984). Public materials generally note no completed senior high / no university degree disclosed — this site adds no speculation.
Forbes lists Residence: Hong Kong. 2025 financial media described him as long-term based in Hong Kong; the same year he acquired a Tin Hau building for CAI Tower and joined the HKSAR Web3 Task Force. Fujian / Xiamen remain early-career and hometown ties, not necessarily current residence.
Media accounts credit early capital from internet-related stock trades (narrative reporting; figures vary by outlet).
Entered the internet industry; known for domain investing; Longling’s site references China webmaster conferences.
Founded 265.com (site navigation); sold to Google in 2007 (official director bios).
Began angel investing; 4399, Meitu and related projects; Longling narrative origin.
Chairman of 4399 Network.
Director of 58.com Inc.
Chairman of Meitu; Meitu listed on HKEX in 2016 (1357.HK).
Media report early OKCoin-related stakes via Longling; 2018 public comments on multiple blockchain projects. Meitu published a blockchain white paper the same year.
Meitu (corporate) purchased BTC/ETH; Cai stepped down as Meitu chairman in June 2023; late 2024 sale of purchased crypto reportedly yielded ~USD 79.63m of profit.
Acquired Tin Hau building renamed CAI Tower; Longling-related control of Long Corp (2312) and CAI Corp (00080); Web3 Task Force member from 1 Jul 2025; CAI Corp chairman & NED from 5 Sep 2025.
Timeline anchors follow CAI Corp / Long Corp official bios, HKSAR press releases, and major financial media; media-only figures are flagged as uncertain.
Platforms
Public posture as of roughly 2025–2026. At Meitu he remains founder and a substantial shareholder, not the current chairman (stepped down June 2023).
Formerly China New Economy Investment; HKEX Main Board investment company. Controlling-shareholder path via Longling Capital Ltd (sole shareholder and sole director). Chairman & non-executive director since 5 Sep 2025. Stated focus: AI and Web3, with an expanding digital-asset portfolio.
Formerly China Financial Leasing; Chapter 21 investment company. Cai serves as board chairman / NED (see company disclosures). Site narrative emphasises crypto and AI digital-asset investing.
Founder and chairman. Site positions a “Crypto-AI startup centre” at Nos. 58 Electric Road, Tin Hau, Hong Kong. Public BP inbox: space@longling.com.
Acquired in 2025 for about HKD 650m and renamed; Cai publicly explained CAI as Crypto + AI. Media describe garage-café / AI-CAFE floors, shared offices, 3–6 month incubation, and priority on first-round financing — media interview narrative, not a regulatory filing.
Founder and current substantial shareholder. Chairman Jul 2013 – Jun 2023; thereafter Wu Xinhong–led AI transformation narratives. 2025 reports of repeated share sales, with holding once cited near 9.95% (rely on latest HKEX filings).

Longling’s site says it has backed “100+” teams including 58.com, 4399 and Meitu — institutional self-description, not an audited list. Theme arc: consumer/internet tools → crypto → AI × Web3 / digital assets.
Thesis
Drawn from public interviews and company websites. Quotes are media-relayed — read them in original context.
“AI is the development of productive forces; Web3 is the development of production relations.”
“I decide very quickly — some important investments are settled in half an hour, and the money is wired.”
Public focus today: AI, Web3 / crypto / digital assets; within Web3 he has highlighted games and sustainable economic models.
People over PPT; integrity, learning ability, passion; preference for grassroots “doers”; dislike of inflated user metrics.
Long identified with angel / early stage. No stable public ticket-size band — do not invent figures.
CAI Corp’s stated objective: diversified global investing with emphasis on AI and Web3, expanding digital assets in line with Hong Kong’s digital-asset hub policy.
Public roles
Newly appointed non-official member for two years from 1 July 2025. Chaired by the Financial Secretary.
Co-chairman, Early-stage Investment Committee, Asset Management Association of China; honorary chairman, Angel Investment Union (per company bios).
Xiamen University SOM (from Sep 2015); HKU Business School adjunct (Sep 2024 – Aug 2025); PolyU Professor of Practice, Data Science & AI (from 2 May 2025).
Public appearances include BEYOND Expo talks and Hong Kong Fujian association events on AI and Web3 (media). Shishi municipal reporting has covered hometown education donations by the Hong Kong–based native.
Public record
Neutral summaries of public reporting. Analysis is not the same as an official corporate explanation.
Large corporate BTC/ETH buys in 2021 later took impairments; critics called the strategy a distraction. Around the June 2023 chair change, some analysts linked the move to crypto losses. Late-2024 sales reportedly locked in substantial accounting gains.
Entertainment/gaming media reported past tensions with certain executives and share rearrangements (historical).
2025 control-related deals in 00080 / 2312 were followed by sharp price moves; stated corporate aims include asset-management and AI/Web3 investing platforms.
2025 reports of repeated disposals; rely on HKEX disclosures for exact sizes and percentages.
Outreach
Practical guidance inferred from public interviews, published submission channels, and media patterns. It is advisory inference — not insider tips, guarantees, or scripts. Nothing here is an offer of securities or virtual assets.
AI, Web3 / digital assets, Crypto×AI, or sustainable Web3 games / creator economy? Far-off sectors may see lower cold-email hit rates.
Public selection logic favours doers and real users/metrics, and dislikes inflation. Bring verifiable demos and numbers — not empty decks.
Longling’s site invites business plans to:
space@longling.comPublic address: Nos. 58 Electric Road, Tin Hau, Hong Kong. CAI Tower / garage-café is a media-described ecosystem path for teams already in (or able to stay in) Hong Kong — still defer to official channels.
Early interviews often cited peer referrals. Use lawful public networks (industry events, angel forums, open university talks). No private contact list is provided here.
CAI Corp, Long Corp, and Meitu IR (e.g. ir@meitu.com) are for investor relations / compliance — not a shortcut to a personal angel meeting.
