We build products, and the companies around them.
Senternet is an independent studio. We ship focused, privacy-first software, and we do the rest of the build too: forming the company, the brand, the operations, and the go-to-market that turn a product into a business.
Products we build and run
Every product is small on purpose: one job, done exceptionally well, with privacy as a default rather than a feature.
Premail
Your inbox, defended.
Our privacy-first desktop app that filters email before it reaches your inbox. Spam, recruiters, and the daily noise get handled quietly. What is left is what actually matters.

Comoji
Slack-style :emoji: autocomplete, everywhere on your Mac.
A tiny macOS menu bar app that brings colon emoji shortcuts to Messages, Mail, Notes, Safari, and most Mac apps. Type :liz, press Tab, get a lizard. Runs locally. Nothing you type is uploaded.

Burly
Every link, in the right browser profile.
A native macOS menu bar app that routes every link to the right browser profile: work links to the work profile, personal links to the personal one. Fast, keyboard-first, and 100% local.

StockCar
A podcast of your portfolio, not the market.
An iOS app that turns the assets you actually hold (stocks, crypto, indices, and FX) into a short, personalized audio briefing with a cast of AI cohosts. No account, no brokerage linking.

All projectsThe team behind the products, on your project
We take on a small number of engagements, from a single app to a whole company. You get the people who design, build, ship, and operate the products above, and who stood up the nonprofit behind Bee Ready end to end.
Product engineering
Idea to shipped product: architecture, native macOS & iOS apps, web, AI, CI/CD, and launch. We build it the way we build our own.
Company building
The parts around the app: entity formation, operations, and the leadership scaffolding a venture needs to run, nonprofit or commercial.
Brand, design & growth
Identity, product design, positioning, and go-to-market. The work that turns something built into something people find and use.
