An independent product house

A house for honest software.

We build our own apps — and do the unglamorous second half too: making sure the right people find them. Grain is the first.

First app, coming to iOS Built & marketed in-house Independent
What Sonder is

Not an agency. A studio that owns what it makes.

We design, build, and market our own software — then live with it after launch. That is the whole difference. An agency hands the product off and moves on; we don't. We answer to the people who use what we ship, not to a brief.

What we've built

Our apps.

One app on the way, with more in early development. We'd rather ship a few things we'd actually use than a lot we wouldn't.

The flagship

Grain is proof of how we build.

Grain reads the label on anything you scan and returns one honest score, with every ingredient explained. Nobody can pay to change it. No ads. No data resale. That independence isn't a Grain feature — it's the Sonder standard, made literal.

The whole arc

We build it, then we make sure it's found.

Most studios do one half. Owning both is why the products stay honest — there's no one to answer to but the person using them.

01

We build

Design and engineering under one roof. Opinionated products, shipped and then maintained — not handed off.

  • Product design & brand
  • iOS & web, end to end
  • Live systems: data, AI, infrastructure
02

We market

The unglamorous second half: the story, the positioning, the site you're reading — getting the right people to the right app.

  • Positioning & narrative
  • Site, content & launch
  • Growth that respects the reader
Selective studio work

We take on a little outside work.

Start a conversation

Most of our time goes to our own apps. But when a founder arrives with something we wish existed, we'll build and launch it with them — same craft, same standards, a short list chosen for fit.

Why we're called Sonder

“Sonder — the realization that each passer-by is living a life as vivid and complex as your own.”

That is not a mood-board word for us. It's the standard. We build software as if a real, specific person is on the other side of the screen — because there always is.

A company that genuinely believes that doesn't sell that person to advertisers, or let a brand buy a better score. Sonder → honesty → the way Grain already behaves.

Grain launches soon, with more to follow. Leave your email and we'll tell you when.
