Specific (YC F25)

Building and deploying an application shouldn't get you stuck on managing infrastructure. We created Specific so your coding agent can define the infrastructure alongside the application code, run everything locally, and deploy it to production. To show what that looks like, we built a full-stack task board from scratch using nothing but Claude Code prompts: → Frontend (React + Vite) → Backend API (Go) → Database (Postgres) → Authentication → Real-time sync across browsers → File storage → Background jobs Every feature follows the same pattern: Prompt → specific dev → specific deploy Full walkthrough in the comments 👇

Turns out Specific hosts more than just your infrastructure. I'm attending Project Barcelona next week and together with the team from Favora, we're hosting a 5K along the beach before everyone disappears into a day and night of building. Run by if you're around 👟

Florent Venture Partners x Lund AI Society: 12-hour AI hackathon. April 18. Supported by: Anthropic, Voyado, Librar Labs (YC W26), Specific (YC F25), Atech. Build something real. Ship it. Win 100k+ SEK. Your hack could be your next startup. Apply: [https://lnkd.in/eNu94Fka].

If you are in or around Lund, you don't want to miss this. We'll be sponsoring participating teams with credits to build anything they can dream up.

Agents are great at writing code, but too much of the other work like configuration of local dev environment and provisioning infrastructure, is still on the developer. Specific (YC F25) solves this with an agent-first cloud. Agents get automatic local dev environments and a Terraform-style IaC layer that gives them the infrastructure context they need to develop, deploy, and maintain apps safely. Also the database layer runs on Neon!

"We use Vercel for the frontend, Supabase for the database and auth, and Railway for the backend.” I’ve heard this from too many founders and I’m genuinely surprised. Not just by the fact that it’s three different platforms to manage your stack, but by the fact that they’ve hit a wall and want to migrate away, but they’re locked in. I get why founders start with them. I spent years working with AWS, GCP and Azure. Even with prior experience, it’s time consuming to battle with setting up a VPC, configuring IAM roles, and deciding which of the 200 services to use for your architecture. Once you set it all up, you end up wishing you started with Terraform from the beginning, but you just wanted to try out that idea of yours. And younger founders skip the major cloud providers entirely because they’d rather spend their time building. So they pick these alternatives because they’re easy to start with, they sound promising, and most likely because they get recommended by coding agents. But a few months in, the cracks show. The cracks that the agent didn’t tell you about because you didn’t ask. Supabase has shaped your architecture. Their auth model, their row-level security, and their SDKs scattered across your codebase. On top of that, you’re operating across three platforms that don’t know about each other. Running your full stack locally on your own machine means you’re the one wiring services together, making sure ports don’t conflict, and juggling .env files so everything can find each other. For the past months, Fabian Lindfors and I have been obsessing about building something that solves all of these pain points. Because what if you could have the developer experience of Vercel but with the building blocks of AWS? That’s what Specific (YC F25) is. With Specific, your entire stack is defined in one config file next to your code. Services, databases, storage, caching, realtime, workflows and more. One CLI command to run the entire stack locally. One command to deploy. No SDKs, no lock-in. Designed for coding agents from day one, because that’s how most people build software today, and even more so moving forward. This is not a vision. It’s live. https://specific.dev/

We recently shared why we are making something for agents. Great to see more humans talking about this topic. Read our post here: https://lnkd.in/dNVUX9z4

I asked Iman Radjavi to explain what they build at Specific (YC F25). He did. I nodded. I understood 40%. PARTNERSHIP. Okay let me explain hehehe. So a few weeks ago I went to a cafe in Stockholm to meet Iman. The plan? Get him to vouch for Ernest Labs to get into Y combinator. That was the whole plan. That's why I was there. But then Iman starts telling me about Specific. Infrastructure-as-code for AI agents. I'm nodding. I'm nodding harder. (Internal monologue: "Jonas what is he saying? Just keep nodding.") And then he shows me the demo. And I go from "I'm lost" to "WAIT HOW DOES NOBODY KNOW ABOUT THIS?!?!" in about 45 seconds. So Iman Radjavi and Fabian Lindfors (Specific (YC F25)) are literally two people. TWO. YC-backed, based right here in Stockholm, and they somehow built the thing that makes AI agents actually work. Like in real life and not just in demos. All the infrastructure stuff, databases, APIs, deployment as code. The boring stuff nobody wants to build? They built it. And it kinda blew my mind?? I was NOT expecting that from "infrastructure tooling." If you're doing ANYTHING with AI agents just... go look at what they built. I'm not even exaggerating for once. These two are gonna be everywhere in a year and I want you to be able to say you found them early. "But Jonas?!?! Why are you so hyped?" Because I went to that cafe to ask for a favor. And walked out going "okay WHAT just happened." Did I get the YC intro I came for? Yes, but I also got something even better. Oh and yeah we're partnering with them at Ernest Labs too. Obviously. Seriously though go check out Specific (YC F25). You can thank me later. #Specific #Stockholm #YCombinator #BuildInPublic #KomIgenDetBlirKul #Ernest
