[ ABOUT US ]

We started an agency because too much software gets talked about instead of built.

Someone in a knit cap planes the hull of an upturned wooden boat with one citrine stripe, while a row of crows caws at each other on the fence behind and one more crow has landed on the boat.
WORKING WITH TEAMS WORLDWIDE

Senior designers and engineers for teams that would rather ship than sit in meetings.

10+

Years shipping software

[ WHO WE ARE ]

Designers and engineers with more than ten years of shipping behind us, and frontend as our sharpest edge.

We build AI features, web apps and mobile apps for startups and established companies, and we ship the full stack with the same confidence as the frontend. Most of our work happens inside a client's team. Some of it starts from a blank page and ends at launch.

[ THE DEAL ]

Give us a clear brief and room to work. You'll see working software every week.

YOU BRING
  • A clear brief, even a rough one
  • One person who can make the call
  • Room for us to do the work
WE BRING
  • Questions until the problem is obvious
  • Working software every week
  • A straight answer when something isn't worth building
Over a dry-stone wall one hand passes a rolled sheet of paper tied with string, while two hands from the other side hold out a new wooden birdhouse with a citrine roof and a sparrow already peeking out.
[ WHAT WE WON'T DO ]

A short list, and we stick to every line of it.

  • Take on work someone else would do better
  • Build what you asked for when it isn't what you need
  • 24hLongest you wait for a reply
  • 5+Industries shipped for
  • 0GPT wrappers sold as products
At night three people raise the timber frame of a small barn in a meadow by the light of one citrine lantern, one on a ladder at the ridge, while an owl sits on the end of the beam and watches.

One team, and the people you talk to are the people who build it.

[ OUR STORY ]10+ YEARS IN. WORKING WORLDWIDE

We spent years watching good ideas die in meetings. So we built an agency that skips the part where nothing happens.

  1. 10+

    Years of shipping software for startups and established companies in hospitality, education, crypto and photography.

  2. WHY

    Too many AI products that were a prompt in a text box, and too many embedded teams that spent the week in standups.

  3. 2025

    ipsilon starts with one rule: a clear brief in, working software out.

  4. NOW

    AI features, web apps and mobile apps for teams worldwide, built by the people you actually talk to.

[ WHAT WE STAND FOR ]

If we're not the right team for it, we'll tell you who is.

What we say before every project
On a hilltop an older man with a walking stick points a traveller with a backpack across the valley to a small workshop with a citrine door, while a dog has already set off down the path toward it.
  1. 01

    Why before how

    Nobody writes code until the problem is clear. Asking the right question early is the cheapest decision on any project.

  2. 02

    Briefs over meetings

    A clear brief and room to work beat a calendar full of check-ins. You hear from us when there's something to show.

  3. 03

    Best person for the job

    If someone is miles ahead of us on part of the work, we bring them in. You get a better result, and we stay accountable for all of it.

  4. 04

    Built to be used

    A demo that impresses is the easy part. We build AI features and software that still hold up after real users arrive.

[ WHO WE WORK WITH ]

Founders, CTOs and product leads who know the problem and want it solved properly.

Startups going from nothing to launch, and established companies that need a senior team inside theirs. We slot into your tools and your release schedule. We prefer contracts and are open to full time roles.

Tell us what you're building and why it matters. We reply within 24 hours with questions, not a sales pitch.

LET'S TALK
Across a sunny gorge one man sends a basket with a citrine envelope along a rope on a pulley, while a second man on the far cliff reaches out for it and a mountain goat watches from a ledge below.
