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.

It's Christmas today, it's also my Birthday! I finally got some time after work to split a mini cake with my friends to the wonderful 2024 for me: @ycombinator , #ForbesUnder30, and my startup Mathos AI became profitable!

JKJK ๐คญ๐คญ๐คญ
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. Itโs 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 ๐๐ฃ๐ข ๐ฐ๐ผ๐บ๐ฝ๐ฎ๐ป๐ถ๐ฒ๐) 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.
Building is never easy. But we feel super grateful for early support from @ycombinator, MiraclePlus, KungHo Fund, @gongyaobin, and now, @Forbes @ForbesUnder30.
Moving forward, we will be soon welcoming support from more people! Stay tuned with @VyvyenYue @quinn_lyu, and our newly joined cofounder @YJyanjia!
Extremely honored to be recognized as #ForbesUnder30, North America, Class of 2025.
It's the best timing for LLMs, as well as a unprecedented opportunity for future education. Stay tuned!

SEO is taking off (even after our rebrand in sept)
we did ZERO SEO in the first ten months of Mathos AI before may
can't imagine what if we push hard on SEO from day 1

I'm presenting my paper at @COLM_conf

Paper accepted to @COLM_conf! If you don't know CoLM, it's Neurips-level, but the ๐ง๐ช๐ณ๐ด๐ต ๐ฆ๐ท๐ฆ๐ณ ๐ค๐ฐ๐ฏ๐ง๐ฆ๐ณ๐ฆ๐ฏ๐ค๐ฆ ๐ง๐ฐ๐ณ ๐๐๐๐ด. Wild.
Publishing papers while building a ๐๐๐ฎ๐ฟ๐๐๐ฝ with ๐ญ๐ + users is never easy.
We developed ๐ฆ๐๐ฎ๐๐ฒ๐๐น๐ผ๐, 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).
๐ฆ๐๐ฎ๐๐ฒ๐๐น๐ผ๐ 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/StateFloโฆ
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 ๐คญ), and @ShaokunZhang1 @qingyun_wu @Chi_Wang_โค๏ธ, and my friends who offer meaningful discussions @hanjundai @ericzelikman @jyangballin @cindy_x_wu
