Launch YC: Carrot Labs: Custom models tuned to your tasks that never stop improving

"Continuous Learning for Production AI."

TL;DR: Carrot Labs helps you build models for your agents that are faster and better, forever. Use their platform to build proprietary models using open source that progressively improve.

Their Launch Video

Founded by Christopher Acker & Yuta Baba

Chris led AI at Skylo Technologies, the world's largest commercial direct-to-device satellite network that provides satellite communications services to Google, Samsung, and Garmin devices.

Yuta was a senior data scientist at Snowflake where he developed financial forecasts through ML that supported the company's hypergrowth from pre-IPO to billions in revenue.

The Problems:

Frontier models from Anthropic, OpenAI and Google are constantly pushing the boundary of intelligence further, but great quality comes with high latency and cost. Smaller models are fast, but can't get the job done right.

So you start modifying system prompts. It takes you far enough, but at some point you hit a ceiling. And every time a new model comes out, your prompts don't work the same way anymore! (just February 2026 alone, Opus 4.6 and Sonnet 4.6 from Anthropic, Gemini 3.1 Pro from Google, GPT-5.3-Codex from Open AI, Qwen 3.5 from Alibaba came out to name a few.)

Solution:

Carrot Labs builds you a proprietary model tuned to your tasks so you always have access to the most performant model for your agent.

Their platform records your agent’s activity and tunes an optimized model from an open source base model. Once it's ready, swap out the frontier model for yours. That's it. As new production data flows in, they continuously evaluate and retrain your model to boost performance. What you get is a model specialized to your tasks that outperforms frontier.

Why this matters to your startup:

In the short run, you need your agent to be faster and more accurate, and prompt tuning will only get you so far. They are the fastest way to get there.

In the long run, every company building agents is using the same frontier models. Your competitor has the same intelligence you do. The thing that differentiates you is the knowledge you distill into your own model. Your model is your moat.

How you can help:

If you are building agents or know anyone building agents who would appreciate a model that outperforms frontier on their tasks, contact the founders here.

Their self-serve agent eval SDKs are available. Feel free to use it! You can sign up from here: https://platform.carrotlabs.ai/login.
