👋 Hello, we're addedPIXELS.

We build
the awkward
bits of tech.

Two humans in Manchester. We write the software, wire up the hardware, and quite often replace the bit of your stack that has been "nearly working" for three years.

…and the awkward integrations between all of them.
a partial list

Lighting is one thing we do.
It is not the only thing.

Custom middleware and small platforms that end the integration headache.

The half-working SaaS stack that's been costing you money for years. The widget that shows last month's events. The form that should hit your CRM but doesn't. The spreadsheet nobody's allowed to touch. We work out what you actually need, then build a small piece of software you own. It retires three subscriptions and the recurring meeting about them.

Consulting

Sometimes you don't need a build, you need a second opinion before someone else's quote turns into a problem.

  • Technical review
  • Vendor selection
  • Architecture sketches
  • Honest second opinions
a back-of-napkin example

"It's been like this for years."
Has it though? Let's fix it.

The conversation usually starts the same way. "This thing is supposed to sync with that thing, and they don't, and someone's job is now updating both by hand." Or "we pay for four tools when really we just need one piece of software that owns the data." The honest answer, most of the time, is that a small custom platform would replace three subscriptions, and the recurring meeting about them, with one thing you own.

The stack you've got:

  • Two systems that won't sync
  • A widget showing stale data
  • Forms not hitting your CRM
  • A monthly report stitched by hand
  • A workflow nobody can edit
we'd build

What replaces it:

  • One small platform you own
  • Single source of truth
  • The integration, in software
  • The report, generated
  • Problem stops being a meeting
selected work

A few things we've actually built.

Provendium, Province-level operational SaaS.

The platform that sits between a Masonic Province and the work it actually does day-to-day: calendars, role assignments, RSVPs, embeds on Lodge websites, Almoner casework. Multi-tenant from day one. Open source under AGPL-3.0. In build, with Cheshire as pilot tenant.

Case 03 · SaaS for Freemasonry Masonic Tracker

Masonic Tracker, a flagship SaaS build.

Two codebases, one product: a multi-tenant platform for Freemasonry (lodges, chapters, provinces, ranks, events, charity transparency, Stripe billing, calendar sync) and the public marketing site that sells it. Built ground-up for a vertical that didn't have a product.

us

Just two people. On purpose.

The person you brief is the person who writes the code, takes the call, climbs the ladder, and remembers what you said in the kickoff. We don't hand off, we don't account-manage. It's just us, and we're answering.

Yannick McCabe-Costa

Managing Director & Co-Founder

The one up the ladder. Codes stuff, makes it work, breaks it, fixes it. Will not be talked out of stapling CAT6 to brickwork.

Oliver Hemsted
Oliver Hemsted
Co-Founder

Writes the code, then quietly resents that it doesn't write itself yet. Occasionally wears CAT6 as a lei.

a brief note

If something's been
"nearly working"
for too long…

…just tell us. We'll look at it. If it's a small thing, we'll say so. If it actually wants a small custom platform of its own (software, the connecting bit, maybe a piece of hardware), we'll be honest about that too. We answer our own email, and there's no funnel.

You can write, or call, or pick whichever country code is nearest:
