Most of what we do is our own apps. The rest of the time we take on work for other people — the same way, with the same standards.
You talk to the person who writes the code. There is no account manager in the middle, no team you never meet, and nothing gets subcontracted to someone we have not worked with.
We take on a few projects at a time on purpose. It is the only way to finish something properly, and it means that if we say yes, you have our attention.
Native, written in Swift for Apple’s own frameworks — not a website in a wrapper. From the first sketch to the app being live on the App Store, including the parts nobody enjoys: review, privacy policies, screenshots and store listings.
Fast, readable on a phone, and built to keep working. No cookie banner, no tracking scripts and nothing loaded from a third party unless you ask for it. The site you are reading is one of ours.
Interface design, a logo and colours that survive being shrunk to 22 pixels, and the App Store artwork that decides whether anyone taps install. We design what we build, so it does not get lost between two suppliers.
An app that got rejected, a site that is slow, a launch that stalled. Sometimes the useful job is not a rewrite: it is finding the one thing that is blocking you and getting it out of the way.
Apps designed, written and prepared for the App Store end to end — interface, code, icon, screenshots and store listing. The same work we would do for you.
This site is ours too. It is generated from a data file, it works in two languages, and it loads nothing from anybody else — no fonts, no analytics, no trackers.
Our own product for businesses: an inbox that reads and sorts your email, answers new enquiries within limits and keeps a CRM up to date on its own.
An email is enough. What it is for, roughly when you need it, and anything you already have — sketches, a document, a half-finished project.
Within a couple of business days, honestly: what we would build, what we would leave out, and whether we are the right people for it. If we are not, we will say so.
Before anything starts, in writing. You know what you are getting and what it costs, and you see it working as it is built, not at the end.
Write to service@sesinit.com with a couple of lines about the project. Our assistant replies first with a question or two, and a person reviews every conversation and follows up — usually within two business days.
We work in English and Spanish, and we are based in the United States. Everything we build is yours: you get the source code, the accounts stay in your name, and you are never locked into us to keep it running.
