Based in London, working across Essex

We are a London IT company that Harlow businesses come to when they want software built properly.

Harlow is one of our strongest spots in Essex. We already build and run systems for real businesses in the town, not stock names on a map.

You get one senior team for the whole job, from first sketch to launch and the support after. Clear pricing, plain English, no fuss.

Two local clients,
two different problems

Could yours be next? ↗
Case 01 · Harlow swim school

Booking that runs itself, every term.

Parents book and pay for the whole term in a couple of taps. We spend Saturdays teaching, not chasing paperwork.

Case 02 · Harlow locksmith

When someone is locked out, they need us now. The site gets them calling in seconds, day or night.

Why businesses stay with us

A partner, not a vendor

(01)

Senior people only

You work with the people who build your project, not a sales team. The founder stays close to every job.

(02)

Built around you

We shape the work around how your business runs, not the other way round. Nothing off the shelf unless it genuinely fits.

(03)

Fast, honest replies

A real reply the same day in working hours, in plain English. No jargon, no chasing, no call centre.

(04)

No surprise invoices

We agree a fixed price in writing before any work starts. You always know what you are paying, and for what.

Clear pricing, no surprises

We will not publish a one size fits all price, because no two projects are the same. But you will never get a surprise invoice from us.

A fixed price, agreed first. After a short call we send a written plan and one clear price. No hourly rates that quietly creep up.

You own everything. The code, the content and the accounts are yours. There is no lock in, ever.

Pay in stages. Most projects are split into clear milestones, so cost follows progress you can see.

Support that suits you. Keep us on for upkeep and new features, or take the lot in house. Your call.

Harlow questions

The honest answers

Ask us anything ↗

Yes, often. We are based in London and work with businesses right across Essex. Most of the project happens remotely, with calls, screen shares and visits when it helps. You get senior people either way.

Of course. We are a short trip away in central London, and we are happy to come to you or meet somewhere convenient in London. For day to day work, a quick call or video usually saves everyone time.

It depends on what you need, but you will always know upfront. After a short call we send a written plan and one fixed price. A focused website might be a few weeks of work, a larger app or system a few months.

No. We build websites, mobile apps, custom software and practical AI, and we look after them afterwards. If you are not sure what you need, that is fine. Tell us the problem and we will suggest the simplest fix.

Usually within a couple of weeks, sometimes sooner. We will give you a realistic start date and timeline with your quote, and we hit the dates we agree.

Yes. We have built a booking system for a Harlow swim school and the online presence for a Harlow locksmith, among others in the town. We are glad to talk you through the work when we speak.
