Autonomous Electrical Engineering

Our first product, Stillwind Search, makes finding an electronic part as easy as writing a text message. The search engine turns natural language queries into fine-grained specifications that are matched against our proprietary database of millions of parts. This is the first step towards autonomous electrical engineering.

Augento 🤖 - DeepSeek reinforcement fine-tuning as-a-service
See original launch post

Hey all 👋, we’re Linus, Hannes, Lukas, and Josef—co-founders of Augento! 🕊️

TL;DR

We align your agents with reinforcement finetuning. You give us your agent, tell us where it fails and we’ll improve it. 🚀

We are actively looking for design partnerships. If you are interested, please shoot us a message at founders@augento.ai 😄

The Problem ❌

🗣️ AI Agents struggle in real-world environments. Even state-of-the-art reasoning models score below 50% accuracy on non-trivial benchmarks.

The solution for many is still prompt engineering & expanding the models' guardrails. However, anyone who’s fought with large prompts knows how draining it can be. You’re never quite sure if the model is really following your instructions or if your tweaks make any difference.

Our Solution ✅

We tackle this by replacing prompt engineering with fine-tuning + RL on your feedback. We integrate with a two lines of code change in your existing system.

The Workflow 💡

1. Swap out your LLM connector URL with ours.

2. We intercept every prompt and output, displaying them in our UI.

3. Where necessary, you give high-level feedback, like your preferred tone or how a tool should actually be used.

4. We continuously post-train the model to match up to your feedback.

5. Once you deem it good enough and want to switch over to the model, you can do that with a click of a button, no changes to your code required.

Our Ask

We’d love your input and are looking for early users to test-drive Augento. Shoot us a message at founders@augento.ai
