About Roastline

The craft lives in one person's head. We're changing that.

Roastline started on a roastery floor, not in a lab — built by people who've stalled a batch, dumped expensive green, and spent weeks training a feel they couldn't write down.

Logging is solved. Decisions aren't.

For twenty years, roasting software has been a rear-view mirror. Tools like Artisan brilliantly record what happened — bean temp, rate of rise, every phase — but on the drum, in the moment, you're still alone with your instincts. The data tells you where you've been, never where you're going.

That gap is expensive. It's the stalled roast you caught a beat too late. The new lot that took eight batches to dial in. The inconsistency between your Tuesday roaster and your Saturday roaster that customers taste before you do. And it's the years it takes to turn a promising hire into someone you'd trust with a single-origin micro-lot.

We didn't want another dashboard. We wanted the master roaster's intuition — available on every machine, every shift.

So we built Roastline: a copilot that reads the curve live, projects where it's heading, predicts how the cup will score before you taste, and — when you want it to — runs your locked-in profiles hands-free. It works with the logging you trust and the machine you already own. It's not here to replace the roaster. It's here to make every roaster as good as your best one.

What we believe

The curve comes first

Every decision is rooted in real telemetry and real cupping outcomes — not vibes, not marketing.

Your data, your floor

The AI can run on-prem and offline. Your roasts are yours — never the price of admission.

A copilot, not autopilot for the soul

You stay in control. The tool amplifies the roaster's judgment — it never pretends to replace it.

Where we are

Early, working, and built in the open.
