For engineering managers

Know how your engineers are actually doing — without asking them.

Sonar is software that connects to the tools your team already works in. It learns how each person normally works, and tells you the moment that changes — someone overloaded, someone stalled, someone quietly carrying the team.

It reads how the work moves — never what anyone wrote.

What to say

“I’ve seen you online really late a lot lately. Everything okay?”

Ever found out something about your team weeks too late?

It’s almost never sudden. It just never reached you.

Underneath that, right now.

  1. Someone's doing twice as much as anyone else. Five weeks now.
  2. Someone else hasn't had anything interesting to do since February.
  3. One's been stuck nine days and stopped mentioning it.
  4. Another holds the team together, and it's written down nowhere.
  5. One's been waiting on you since Tuesday.
  6. And you're about to hire, when you've already got someone idle.

Every one of those is worth knowing today. None of them will reach you.

Your board tracks tickets. It knows the work moved. It doesn’t know it took someone until midnight to move it, or that one person did most of it, or that another barely touched it.

And none of it’s the kind of thing people bring up on their own.

0%

of burnt out people have never told their manager. By the time anyone says it out loud, it’s usually been true for months.

Six months later, here’s what it cost.

  • The overloaded one resigns. Replacing them takes six months to a year — hiring, then getting someone up to speed, plus everything they knew that was never written down.
  • The one with nothing to do leaves a month later. Everybody calls it a surprise.
  • The one holding it together gets passed over at review, because none of it was on a ticket.
  • And your new hire's doing the work somebody already on the team was asking for.

You found out about every one of them too late to do anything.

Every one of those was preventable.

None of them happened overnight. All six built up over weeks, in small changes, in the tools your team already uses.

One late night is one late night. A slow reply is a busy day. On its own, none of it means anything.

But the same person, working further from how they normally work, week after week — that shows up months before anyone hands in their notice.

Sonar catches it in week two, not month six.

It takes two weeks to learn how each person on your team normally works. Then it watches what changes.

Not people who work late — plenty always have, and they’re fine. People working differently than they did a month ago, and moving further from it every week.

17 signals. Overload. Stuck work. Underuse. Invisible work. Every person, every day. You hear about it the week it starts.

And tells you exactly what to say.

“How’s it going?” will always get you “fine.” You’re asking someone to raise a problem, unprompted, with their boss.

But if you already know they’ve been online past 11 on nineteen nights this month, you can just say:

“

I’ve seen you online really late a lot lately. Everything okay?

They don’t have to bring it up. You already did.

People won’t start a hard conversation. Most people will finish one.

This is what lands in your inbox.

Most mornings it’s nothing serious. Someone’s got room for more. Someone’s stuck. Someone did good work and nobody noticed. You sort it while it’s still small.

Reads work patterns only. Never message contents.

It never reads messages.

Sonar reads the shape of the work, never the content. It can tell someone’s pulled away from a conversation they used to be at the centre of. It’s got no idea what that conversation was about.

Your team sees what you see. Everyone gets their own page showing what Sonar holds about them, and can ask you to pause or delete it.

Nothing goes to HR. No scores. No rankings.

Your board will still be green. Now you’ll know what’s under it.

Connect the tools your team already works in. Sonar starts learning tonight.

Why it exists

I kept finding out too late.

Twice I learned a strong engineer was halfway out the door the same week they finally told me. The signs had been there for a month — scattered across tools I wasn’t watching. By the time it reached me, the conversation was a goodbye, not a save. I wanted the one that came earlier.

“The right product for a manager isn’t surveillance over their team. It’s the conversation they didn’t know to schedule.”
