2025, I made hard decisions. Turned down acq offers to solve what's 10x. Turned down millions of funding. Became a solo founder. Cut team 6 โ†’ 3; rebuilt to 7. One key responsibility of a leader is to make hard decisions, quickly. The other is to empower. I trusted someone with no experience in growth or startup to lead our UGC growth from 0 to 6M views/mo in just two months. I hired someone in early 20s to lead our new mobile app dev, uiux, paywall from 0 to 1, almost unsupervised. I guided our amazing sr. eng into a powerful CTO that backs the whole team firmly. I never felt this much of responsibility to lift others' career while being supported back wholeheartedly. What I gave out now started to empower me. An exciting new year ahead. Be brave.

How to prove that I didn't pay for this ๐Ÿ†˜? JKJK ๐Ÿคญ๐Ÿคญ๐Ÿคญ Feel super grateful! Also, I would like to share below the story I told Forbes Journalist Katherine Love when I was reached out as the nominee a few months ago: # Brief Background I have loved math since I was young. I was admitted to a top university in China at just 14 years old due to my strong performance in math competitions. Then I moved to the U.S. in 2018 to further study Natural Language Processing (NLP) at Carnegie Mellon University, where I experienced firsthand the transformative power of language models. # Motivation As ChatGPT completely transformed the way people acquire information, I recognized an unprecedented opportunity to revolutionize education. Meanwhile, I noticed many people are still suffering from learning math, while I have loved and benefited a lot from math. So I decided to build something that can help. # What We Built Our featured app is a multimodal personalized AI math tutor that allows students to Circle & Ask, Draw, Scratch, and Talk, all at once, seamlessly, and learn at their optimized pace. Itโ€™s like having a supportive math teacher right by your side with infinite patience. We have also developed a comprehensive RAG system to answer questions in a way that is aligned with the curriculum and offer that as an API to empower next-generation personalized learning platforms. # Relevant Facts and Figures We have crossed 1M users within a year by organic growth. We have raised 1.84M (oversubscribed!) very quickly. Our model has 15% accuracy improvement over GPT4o on high school and college level math problems. We have also partnered with some EdTech companies (including ๐—œ๐—ฃ๐—ข ๐—ฐ๐—ผ๐—บ๐—ฝ๐—ฎ๐—ป๐—ถ๐—ฒ๐˜€) to offer API and personalized learning solutions. # Mission We want to empower everyone to learn anything from anywhere. Starting with the AI Math Tutor, we are envisioning a future where quality, affordable, and personalized learning experiences are accessible to all people. Looking forward, we will keep expanding and utilize @Mathos to empower teachers, school districts, and parents to best understand and assist their kids, in order to improve personalized education at population level.

Paper accepted to @COLM_conf! If you don't know CoLM, it's Neurips-level, but the ๐˜ง๐˜ช๐˜ณ๐˜ด๐˜ต ๐˜ฆ๐˜ท๐˜ฆ๐˜ณ ๐˜ค๐˜ฐ๐˜ฏ๐˜ง๐˜ฆ๐˜ณ๐˜ฆ๐˜ฏ๐˜ค๐˜ฆ ๐˜ง๐˜ฐ๐˜ณ ๐˜“๐˜“๐˜”๐˜ด. Wild. Publishing papers while building a ๐˜€๐˜๐—ฎ๐—ฟ๐˜๐˜‚๐—ฝ with ๐Ÿญ๐—  users is never easy. We developed ๐—ฆ๐˜๐—ฎ๐˜๐—ฒ๐—™๐—น๐—ผ๐˜„, a framework to better control LLM to solve highly complex tasks, with significant performance gain but 5x cheaper cost. It also allows further improvement by combining with iterative refining methods (e.g. Reflexion). ๐—ฆ๐˜๐—ฎ๐˜๐—ฒ๐—™๐—น๐—ผ๐˜„ was also quickly integrated with @pyautogen and "noticeably improved" (cited from a user testimonial) the performance (28.3k โญ). AutoGen: github.com/microsoft/autogen StateFlow: github.com/yiranwu0/StateFloโ€ฆ Thanks my amazing co-authors especially @YiranWu18 who iterates this idea over and over again with me (well, we also iterated the paper name a lot ๐Ÿคญ), and @ShaokunZhang1 @qingyun_wu @Chi_Wang_โค๏ธ, and my friends who offer meaningful discussions @hanjundai @ericzelikman @jyangballin @cindy_x_wu Here are more insights:
