😸 Ideas that print money

gm legends, happy Friday.

Here’s today’s lineup: Calk gives teams a way to use agents with real company data without mapping out workflows, Hera offers a quiet period tracker that doesn’t feel like another inbox, and Agenta helps AI teams ship LLM features without prompts living in five different places.

Calk AI gives you AI agents that actually work with your real company data without asking you to build workflows or map out diagrams. You connect your tools, describe the task, and the agent handles things like reporting, cleaning, writing and updating across your stack. It can schedule tasks, push changes back into your tools, and grow with extra abilities as you need them, all without forcing you to learn automation logic.

🔥 Our Take: Honestly, the draw here is that you don’t have to think like an engineer to get something useful out of it. You hook up your tools, say what you want done, and the agent runs with it. No flowcharts, no boxes and arrows, no guessing why something broke. It feels closer to the kind of help people actually need when they’re drowning in small tasks and scattered data.

Ray started a thread asking whether tech is sleeping on “boring” businesses. Not the AI-agent fireworks, but the quiet tools built for invoicing quirks, compliance headaches, odd scheduling needs and back-office problems nobody tweets about.

He’s asking if people’s idea of “worth building” has shifted. Would you pick a calm, unsexy niche with real demand, or do the louder consumer spaces still pull you in. And for anyone already building in a boring corner of the world, how that choice has actually played out.

If you’ve got thoughts on where the real opportunities are hiding, this is the place to drop them.

Hera is a lightweight period tracker that gives you the basics without turning it into a whole project. You log your period, add symptoms if you want, and it shows you what your cycle is doing in a way that’s actually clear. The design stays quiet, the reminders help when you need them, and everything stays private.

🔥 Our Take: The appeal here is pretty simple. You open it, track what you need, close it, and go on with your day. No pressure, no clutter, no feeling like you’re being nudged into becoming a full-time data analyst. Just enough information to feel connected to what your body is doing without any of the noise.

Agenta is an open-source platform that helps teams build AI features without juggling prompts in spreadsheets or guessing what breaks in production. You get a shared playground for trying prompts and models, a simple way to ship changes without touching code, test cases to check your work before it goes live, and monitoring so you actually know how things perform once users hit it.

🔥 Our Take: Anyone who’s built an AI feature knows the pain: one prompt fix breaks something else, half the logic lives in docs, and no one is ever totally sure what’s running in production. Agenta is trying to wrestle that mess into something the whole team can use.
