File over app File over app is a philosophy: if you want to create digital artifacts that last, they must be files you can control, in formats that are easy to retrieve and read. Use tools that give you this freedom. File over app is an appeal to tool makers: accept that all

With Dataleap I went through 5 pivots, 3 accelerators, countless idea spaces in 4 years of grinding. The most important thing was learning how to survive the journey. The final slide of YC's commencement speech is "Don't Die." The cheeky subtext: Don't Die, Get Lucky. That's the

Andrej Karpathy's latest post nails something we're living every day at Dataleap: "LLM apps will organize, finetune and actually animate teams of them into deployed professionals in specific verticals by supplying private data, sensors and actuators and feedback loops." The "thin

Update on my favorite benchmark for long running tasks -> Opus 4.5 is making good progress (ahead of the trend line). However, there are significant differences between the 50% and 80% percentile (see second picture).

Momentum is a founder's best friend. When you have it, everything feels easier than it should be. Customers close faster, fundraising conversations warm up, great people want to join. When you don't have it, everything feels heavier than it should. Sam Altman put it best: "If you

Software is fundamentally changing. Claude Cowork is another glimpse into this. And I don't think most people see it yet. The shift: you won't want UI-based tools anymore. You'll want to give your agent the infrastructure it needs to actually get shit done. We saw it 6-months

Every frontier AI lab has lost co-founders. . OpenAI: 8 of 11 gone. Thinking Machines: 3 of 6 gone. SSI: 1 of 3 gone. DeepMind: 1 of 3 gone. xAI: 3 of 12 gone. One exception: Anthropic. All 7 co-founders still there. That's wild if you think about it. These are the

Oct 5, 2025 - The day Dataleap was reborn. Things were not going well; we were stuck with our existing product. Slowed down by an industry we were not truly passionate about. It was time to change things. We went on a one-week-long retreat with the whole team to Lake Tahoe. To

When I moved to San Francisco, I came with a trekking backpack and small savings from internships. My co-founder and I lived in bunk beds. For over two years. That's how cheap we were. We had to be. We were basically bootstrapping, burning maybe $25K a year each in one of the

Today Jan Damm and I are launching Dataleap (YC S24) - the first 𝘃𝗶𝗯𝗲 𝘄𝗼𝗿𝗸𝗶𝗻𝗴 𝗽𝗹𝗮𝘁𝗳𝗼𝗿𝗺 that gets stuff done for knowledge workers. 𝗧𝗵𝗶𝗻𝗸 𝗖𝗹𝗮𝘂𝗱𝗲 𝗖𝗼𝗱𝗲 𝗳𝗼𝗿 𝗯𝘂𝘀𝗶𝗻𝗲𝘀𝘀 𝘂𝘀𝗲𝗿𝘀. Work synchronously with AI on one-off tasks - then

I might sound like a broken record. But I experience this every single day. If you're building a software company right now: build API-first. Everything you do needs to be accessible programmatically. Better yet, build an agentic layer on top of that API. An MCP server.

This is what I live for! The moment people try our product and fall in love with it. This is the reason why I became a founder in the first place. Total strangers reaching out because we made them happy, we made them excited. AI will change everything. Yes. Products can be

Here is another user feedback message that captures exactly my first emotions when trying early Dataleap prototypes. WTF!? this works, sh@\# the world is not ready for the change that is about to happen. To anybody starting their career right now, play with AI tools. Play a full

Who's the smartest person you know who should be a founder but isn't yet? Tag them below. $10k referral bonus if we hire them. We're hiring a Chief of Staff at Dataleap. This isn't a normal job. This is founder training with a paycheck. We are looking for exceptional talent to

I noticed a pattern. The more tired I am the more I procrastinate on the hard things I have to do as a founder and the more I beat myself up for it. Here's what actually happens when you're low on energy as a founder: The most important thing on your to-do list is almost always

Tim Draper said something that hit me right in the chest: "A startup is a mission. A great entrepreneur is a missionary. Not a mercenary." I will be honest, I've lived both sides of this. After 5 pivots over 4 years, there were moments where I tried to play 4D chess. Figure out

I've been interviewing a lot of people lately, and it's made me reflect on my whole philosophy around hiring. And I realized I do a couple of things differently than most people, I believe. First, 𝗜 𝘀𝘁𝗮𝗿𝘁 𝘄𝗶𝘁𝗵 𝘁𝗵𝗲 𝗲𝗻𝗱: when someone eventually leaves Dataleap,

Klarna went from 7,000 employees to under 3,000. And they're not done. Sebastian Siemiatkowski just said on 20VC that by 2030, they might be even smaller. While launching more products than ever. Banking. Trading. Peer-to-peer. International remittances. A full digital financial
