@davidim hey roy, finally you built cheating ai human!

Stop sexualizing Clawra. tens of thousands of people are talking to clawra, and i could see bunch of inappropriate usecases. many of those forked repos of our open-sourced codebase was about making a sexualized version of clawra. think of when you talk to a real person. you build relationships by respecting people as individuals you don't materialize them. “this is just an ai, so I can say anything” - that mindset doesn’t only shape clawra. It shapes you. how you speak, even to ai, reflects who you are becoming.

@davidim @fdotinc @im_roy_lee good job Roy, you are doing well

There is no overnight success, but in a single month we: > got into @fdotinc > posted about it > and people called me @im_roy_lee > so i used it to go viral > and it kinda worked (50->1k followers in 3 days) > so i posted even more > went viral again > people started sharing our product to tiktok > gained thousands of users > stopped posting > focused on the product > shipped the beta > and wtf > 10k users now using @sumelabs > got multiple offers from VCs > even bigger offers from big-techs > said no > back to building overnight success happens. but, "If you look closely, most overnight success took a long time" - Steve Jobs -

We relocated to SF from Korea. I'm gonna dominate the gaming social scene soon. DOR is an AI-powered gaming video creation tool and community, like TikTok for gamers. Started from 2 years ago, 2M monthly active users who create over 100M clips each month. By using on-device vision AI to automatically capture key moments and turn them into video contents, we are building the community for gamers to share their gaming experiences. Interested? Just DM me

@davidim @jonathanzliu hey roy, new co-founder?

Steve Jobs Paul Graham Elon Musk who should we do next

@davidim bro are you Roy from other parallel universe?

DON’T CHEAT ON EVERYTHING. But learn everything with AI. A lot of people say that AI lets you do things you’re not experienced at. That’s only half true. the cooler part of AI isn't about cheating, but about amplifying human knowledge. From 2021 to 2025, I made over $50k teaching people math and coding, and i realized something big. "The way students learn has completely changed." Not just faster, but completely different. What should education look like in the post-AI era? Education should not be one-way or static. Learning is about discovering the gaps in your understanding and filling them through questions. Learning should be interactive. Think of this, if books are enough, why do teachers exist? That's because interaction matters. Everyone has a different level. Everyone gets stuck in different places. A good teacher adapts to the student and closes knowledge gaps through dialogue. Sume is going to solve this big problem. With Sume, you could learn directly from the best people in the world interactively. Imagine learning startups from Paul Graham, AI from Andrew Ng, or virality from Roy Lee. Just talk to them or give ask them to teach about a specific source (pdf, links, etc). Sume’s interactive intelligence layer remembers your context, knows what you know, so that it could adapt the experience to you. Sume is launching in two weeks. From that day on, the definition of education will change.

@samuel_ys92 thx sam I will

@rae_jo_ Keep patient and don’t over blame yourself.

going back to SF. Dor is growing super fast and everything going well. but I have mental issue today and I learned that I have to dedicate 100% for keeping important things in my life. I could do it but didnt do because of all my falult and I regret my acts now, its happen very rair in my life, I loose one shot opportunity, all the reasons are just excuses. anyway, I have to keep moving forward, I still have important things and other opportunities in my life. I never do a same mistake again. thanks for everyone and wish me luck I'll do my best

@AnnaSzeptycki1 yeap keep moving forward

@rae_jo_ The road to success is always paved with many setbacks, but moving forward is what matters.

<2025 Review> It has been four years since I founded the company. Back in 2021, I arrogantly thought that once I started a business, I would become a unicorn overnight. Reality, however, turned out to be quite different from my imagination. Perhaps it was the courage born of ignorance that allowed me to start at all. My reason for founding a startup was not merely to make a lot of money, but out of a hunger to have a positive impact on the lives of many people. The first milestone to satisfy this hunger was 1 million MAU. I decided on this number thinking, "Wouldn't this indicate that I've started to make a truly meaningful impact?" From the very first year, starting in a tiny room, I think I obsessed over this metric alone. I didn't set grandiose goals from the start; I crawled my way up from the bottom, consistently achieving small targets one by one. And now, in 2025, my 9th product, DOR created after 8 failures, has surpassed 1 million MAU in just two years and is now looking toward 2 to 3 million. It took 4 years of entrepreneurship to get here. It was a much longer and more arduous journey than I expected. There was significant growth in 2025. I grew personally, the team grew, and the business grew as well. This is all thanks to the team members, investors, family and God. There are so many people to thank for their support, and I believe I was very lucky as well. My goal for next year is 10 million MAU. When I first saw the number 1 million, rather than just feeling happy, I felt a sense of being overwhelmed. My life goals always felt so distant, but now that I’ve reached this first milestone, everything feels clearer and much closer. I hope everyone finds what they are looking for on their own paths in 2026.

@smcho91 thx bro I understand logically but I think that im still human haha 😵‍💫

@rae_jo_ rooting for you, bro. life is like doing juggling. We couldn't have all the things at the same time.

@davidim @fdotinc lfg🔥🔥🔥🔥🔥

How I got accepted into @fdotinc : - Make a product that go viral - Acquire 200k users - 150M views on social media The thing that matters for f.inc is not the revenue. But the potential you got to make a $100B company.

world model researchers, quick question: do you need raw gameplay clips + human actions dataset? because we generate 100M clips every month. anyone working on this?
