Brief

Taste Labs, led by CEO Thais Castello Branco, exited stealth on 2026-06-19 with an $18.5M seed round (CRV, Amplify Partners). Branco says inbound demand 48 hours after launch is “absolutely insane” and that pre-launch demand outstripped capacity. The company seeks to give AI “taste,” focusing on design through post-training data, RL environments, and agent verification tools.

Just 48 hours after launch, Taste Labs CEO @thaiscbranco_ says inbound demand has been "absolutely insane."

"The reason we took so long to launch is because we already had more demand than we could serve even before the launch. I'm still trying to wrap my head around it."

We’re excited to introduce Taste Labs.

Our mission is to end AI slop. We’re building the data and infrastructure layer to give AI models and agents taste.

And today we’re coming out of stealth, announcing our $18.5M seed funding, co-led by @CRV and @AmplifyPartners

AI has nailed objective domains and made it easy to generate anything. But it still feels off. Now, the challenge is judgement. What fits, what feels like you, what’s GREAT. This requires turning a fuzzy, subjective domain into something we can measure and codify. We’re starting with design.

There are two sides to cracking this, the foundation model layer and the agent layer:

  • We’ve already been working with the top frontier labs to evaluate and improve their models, crafting the right post-training data and RL environments.
  • We’ve also been working with app-layer companies to build the context and verification tools for their agents to produce better, more on-brand, more creative outputs.

We want a future where AI feels right.

If you’re passionate about this mission, join us!
