I'm a founding engineer at Lovable. A year ago we started our enterprise platform from scratch, and grew it to Fortune 500 companies without shipping a single enterprise-only feature. Here's how:

This Sunday. 120 global community-hosted events. Demand beyond what we can meet. This is a movement, this is our moat, this is job creation in the age of AI. We're hiring a head of community. It's going to be an insane ride. Who is the person I'm looking for?

Lovable will be free to use for everyone on International Women's Day this Sunday in partnership with @AnthropicAI. Over 120 in-person events are being hosted across the globe by the Lovable SheBuilds community, and we're live-streaming from the Lovable office. See more details: shebuilds.lovable.app

@HarryStebbings Love it and would like more time to personally build - my own level remains very superficial. Better is to get demos from the talented team @creandum Best is to ask anyone in companies I work with take me through their stack. Really valuable even when most details escape me.

"If you are an investor today and you have not downloaded the tools and tried to build something yourself, you are at a fundamental disadvantage. You do not have the skillset to properly evaluate the companies you are looking at. You have to understand how powerful these tools are before you make investment decisions." @klarnaseb How did deeply using these tools change the way you invest @jasonlk @rabois @_fredrik @alexisohanian

@AlexandrePesant So strong. Well done Alex + team!

Lovable has improved dramatically the last 2 months, and all metrics show it. Users build and publish more than ever. We're now taking it to the next level.

@FabianHedin Love the browser testing part. So smooth.

planning + prompt queue + browser testing = ❤️

@antonosika Nice pics, beautiful space!

Today we are officially opening Lovable's new Stockholm HQ. A year ago, the Lovable team fit in an 8-person office. Our new space has room for 300 people across 3 floors! I have a feeling a lot of defining things will happen here.

Listen to this! @alanchanguk & @HarryStebbings - amazing combo!!

@felixhhaas You’re the best!!!

Announcing our $330M Series B 🚀 This has been, without question, the wildest ride I’ve ever been on. What excites me every single day are the people building with Lovable. It all started with individuals shipping small tools. Today, some of the world’s largest enterprises use Lovable to build apps with their own data. Those apps have received 500M+ visits in the last 6 months alone. None of this happens without the team. The 120 incredibly talented people I get to work with every single day. Many moved across the world to help build a generational company from Europe. They’re the reason Lovable is trusted by millions and I couldn't be more excited to be a part of this team. Welcome to the age of the builder. LFG

This is the age of the builder. Thanks @antonosika, @FabianHedin and the whole @Lovable team for changing the interface to software building, forever.

Word!!

Everyone’s a builder!

Beautiful! I'm getting Merch!!

The State of AI in SaaS: SaaS is Dead, Long Live SaaS This started as an analysis of Andrej Karpathy's excellent overview of AI's capabilities. Those who deeply understand this will make all the returns and everyone else will lose a lot of money. "Ghosts" is a brilliant metaphor for what we've created. They're not animals, and they're definitely not human. They are imperfect replicas of us. Karpathy describes them as a "statistical distillation of humanity's documents". AI channels that distribution more effectively than any human and can beat us at Go, schoolwork, analyzing medical images, and many well defined tasks. At the same time, it lacks the reward systems that humans use to improve including curiosity, empowerment, play, intrinsic motivation, and culture. As a result, AI's capabilities are limited. If you watch how the best work gets done with AI, it happens in chunks where a human supervises the output and gives iterative feedback to the AI. Large scale autonomous agents are brittle and fail quickly. Watch anyone vibe code an application with any level of novel complexity. AI also faces integration barriers into existing organizations. AI is not capable of pulling a lot of the levers you need to be effective like coordinating with multiple stakeholders, building trust, authenticity, and interacting with different modalities across time and space. You could argue that the average human doesn't either, but people know when they're interacting with an AI and don't allow it the same agency as they do to people. The most successful AI B2B companies actually need more humans to integrate what they've built (forward deployed engineers) than traditional B2B SaaS. What's next? Those who understand AI and its limitations will transform the industry. Incumbents will be killed by those who know how to leverage AI. I've seen countless homepages talk about being the "AI platform for AI agents" but can't even string a demo together. Meanwhile they're trying to pitch a future where fully autonomous entities collaborate in parallel to write all the code and humans are useless. They will be the first to be replaced when they get surpassed by AI native companies. The investors blindly throwing money into companies at 100x multiples are going to lose their money. I spoke with one of the most disciplined investors I know last week. They said they felt they had to play the game on the field even though they knew it didn't make sense. And this was from someone who is closer to the technology than 95% of investors. On the other hand, companies who deeply understand AI will win everything. Cursor, Glean, Decagon, Sierra, Linear, Lovable, Replit, Bolt, and many AI natives are off to a great start. While 90% of incumbents haven't adapted, it is possible. Figma, Notion, Vercel, Box, and Intercom have done a great job of tearing down what they have and rebuilding AI native products. They have teams who are close to the current capabilities of the models. They also understand their problem domain and as new capabilities come out know what capabilities will map well to what problems in what way. They are able to deliver on AI's promise to their customers. Whereas the majority of existing companies will die. In analytics, the door is wide open. In spite of many of our competitors filling up their homepages with the text "AI", I haven't seen a single compelling demo. We're still working like it's 2015. This will change. We have spent the last year at Amplitude rebuilding our team to be AI native. We've learned about what models are capable of, how to write prompts, and how to leverage evals for building great products. We've worked with our customers to see what gets used in practice and what doesn't. We are building a vision for the future of analytics. We are all in on AI at Amplitude. Stay tuned for what's next. We're going to be fast and furious with AI products at Amplitude.

We launched Lovable Cloud two weeks ago and growth increased by 30%. Supabase doubled the number of weekly new databases created, and external providers could barely keep up. Recap: //1

🚨 BREAKING: Sora 2 is now live on @superscale_ai! After an absolutely insane night, we are the first AI ads platform with full Sora 2 integration. Just 12 hours after OpenAI’s announcement, you can already build your first Sora 2 video ads directly inside Superscale AI - bringing the world’s most advanced video model straight into your ad creation workflow ⚡ Here’s what that night looked like: - 8:30 pm: OpenAI announces the Sora 2 API. - 8:40 pm: Slack channel “sora-2” is created. - 9:59 pm: Integration released to staging (Our engineering team is absolute insane) - 12:00 am: Internal testing done. First ads built. - 10:30 am: Launching Sora 2 on Superscale. That’s what AI-native speed looks like in our team, from global release to live product overnight. AI video ad quality has just reached a completely new level, and it’s available for you right now. This ad was two lines of prompting in Superscale. Comment “Sora 2” for the prompt guide on how to build ads with Sora 2 and for the discount code for your first month. Let’s see what you can build in the next 12 hours 🔥

@PatrickHaede @superscale_ai Love the timeline here - well done @PatrickHaede and team @superscale_ai

@ekzhang1 @modal Amazing work & achievement. Congrats!

Quite a long journey, but @modal has indeed made it. I guess I can now say that I've taken a company from pre-product to $1B Kind of insane to think abt

It's true – @modal has raised a $87M Series B at a $1.1B valuation to advance the future of AI infrastructure.  Thank you to @Lux_Capital, @Redpoint, @AmplifyPartners, and others. Now more than ever, AI demands a complete reinvention of traditional compute infrastructure

@bernhardsson @modal @Lux_Capital @Redpoint @AmplifyPartners So strong. Happy for @creandum to be a small part (but big ambassadors) for @bernhardsson and @modal.
