In 2011, he co-developed the location-sharing app Glassmap with Jonathan Zhang and Jonathan Chang. The idea came from the three having trouble finding friends in the crowd while watching the Orange Bowl; they began coding a prototype in the spring, continued development over the summer, and then promoted it to Stanford students. Woo handled the Facebook and Android work.⁠[3]

He and his partners left Stanford’s master’s program to start the company. Glassmap joined Y Combinator’s Summer 2011 batch, with Woo as co-founder and CEO.⁠[4][5]

On an episode of Shark Tank aired in December 2016, Woo and Brandt sought $2 million for Nootrobox in exchange for 5% equity, implying a $40 million valuation, but did not get an investment from the sharks. The sharks questioned the valuation, the product, and the evidence on long-term health. Woo later told Inc. that brand exposure was also a consideration in appearing on the show.⁠[10]

In June 2017, the company changed its name from Nootrobox to HVMN, short for Health Via Modern Nutrition.⁠[11]

On December 18, 2017, a cognitive supplement study co-authored by Woo was published online in the Journal of Cognitive Enhancement and was later included in the March 2018 issue. The study involved 21 healthy students and used a randomized, double-blind, crossover design to compare the CAF+ formula, caffeine, and a placebo.⁠[12]

The paper found no positive effect of CAF+ on objective cognitive function at the doses and task conditions tested; the authors recommended further study of dosage, complex tasks, and other age groups. The paper disclosed that the study was sponsored by Nootrobox. A March 2018 correction specified Woo’s affiliation as HVMN; the trial’s conclusions apply to the specific formula and conditions.⁠[12][13]

On April 4, 2018, Woo said in a company update that the first batch of HVMN Ketone had shipped the previous week and that the company was continuing to expand supply. This shipping milestone came after the product’s presales began in 2017.⁠[14]

HVMN later formally announced that in 2019 it received a $6 million research and development contract from the U.S. Department of Defense to study ketone supplements and performance under conditions such as high altitude and hypoxia. The research areas described in the announcement include cognition, physiological reserve, and oxygen supply; this is a research and development contract and research arrangement.⁠[15]

On February 24, 2026, Woo wrote a post introducing AntiHunterAI, his personal AI agent experiment. He recounted that he began setting up OpenClawOpenClawOpenClaw is open-source personal AI assistant software created by Peter Steinberger: users run its gateway on their own computer and give instructions to an AI agent through chat apps such as WhatsApp, Telegram, and Discord, and the agent calls tools to carry out tasks. The project was released in November 2025 under the name Warelay, was later renamed Clawdbot and then Moltbot, settled on the name OpenClaw in January 2026 and quickly went viral, while drawing criticism over security risks such as public exposure, malicious plugins, and prompt injection; as of October 2026 it is stewarded by the nonprofit OpenClaw Foundation and open-sourced under the MIT License.Open the full entry in late January, created the agent on February 6, and then continued expanding the devices it runs on and the ways of interacting with it. He called it an experiment in exploring artificial general intelligence.⁠[28]

Woo envisioned the agent earning revenue to obtain more computing resources and trying directions such as trading, prediction markets, or software services. He also noted that early-stage venture investing relies on private information and personal contact, where current agents do not necessarily have a competitive advantage. These are his experimental goals and judgments.⁠[28]

In an a16z interview released on June 22, 2026, Woo and Jake Paul introduced Anti Fund’s $100 million growth fund. Woo argued that as AI lowers the cost of some technical work, trust, attention, and relationships become more important in business competition.⁠[29]

In his advice to young people, Woo still emphasized foundations in mathematics and computer science, and said that one can prove one’s ability through school, competitions, or high-level skills. On choosing founders, he looks for intense interest, the potential to become an excellent practitioner in their field, and the ability to keep practicing and withstand setbacks.⁠[29]

On August 19, 2026, in a published excerpt from the fund’s monthly letter, Woo said that Anti Fund Growth I had officially closed at more than $110 million, above its original $100 million target.⁠[30]

He summarized his investment thesis as value flowing to scarce resources: as verifiable intelligence becomes cheap, manufacturing capacity, proprietary data, trust, and attention may become more important. He explained that early-stage investing focuses on scarce talent, while the growth stage focuses on opportunities to invest in high-quality companies. This was his investment framework at the time.⁠[30]
