About Len

I’m Zhou Liang (周良), and I go by Len. I’m a product manager and a Scorpio born in 1995. Here are some highlights from my career. Feel free to reach out if you’d like to connect:

Experience

• 2026.04–Present
  Head of Product & Operations at Tiandun Data

  • I joined Tiandun Data, a core subsidiary of Hong Kong-listed GBA AI Cloud, to lead product and operations for its API token business in China and internationally.
• 2023–2026.04
  Building Products with AI

  • In 2023, partnered up to create short-form videos using Midjourney, achieving several million-view hits and even had a video top Douyin's trending chart with tens of millions of views. That same year, I used AI-generated comics to make short video dramas and explore whether there was a business in them.
  • I used vibe coding to build my own products as a team of one and helped consulting clients use AI to work more efficiently:

  Crypto Airdrop & Arbitrage Fund

  • Launched a crypto airdrop fund that returned tens of times the initial investment to limited partners within a year.
  • Raised and ran an eight-figure US dollar stablecoin arbitrage fund. The fund earned 40% in its first year and distributed the gains. It later lost US$2.3 million in principal, which I reimbursed in full with my own money. Its annualized return over its lifetime was about 18%.
