About Nexum Forge
A senior only commerce engineering team that owns the full stack: storefront, backend, integrations, infrastructure and QA, under one point of accountability.
Why we exist
Commerce projects fail in the seams
An agency builds the front end. A systems integrator owns the ERP link. A hosting partner runs the infrastructure. Then checkout drops at nine on a Friday in November and three companies explain, politely and at length, why it is not their part.
Nexum Forge was founded in 2016 by four engineers who had spent the previous decade on the wrong end of that phone call. The idea was narrow and has not changed: one senior team that owns the storefront, the services, the integrations, the infrastructure and the support, so there is exactly one person to call and exactly one answer.
We are deliberately small. Thirty eight people, all senior, all working on commerce. We turn down work that does not fit, we tell clients when the cheaper option is the right one, and we take no commission from any vendor in the stack.

Six things we will not trade
These are not values on a wall. Each one has cost us revenue at least once, which is the only real test of whether a principle is a principle.
01
Say the number
If we do not know how long something will take, we say so and then find out. We do not give a date to end a difficult conversation.
02
Senior only
Nobody learns on a client’s budget. We would rather turn work down than staff it with people who are not ready.
03
No vendor commission
We take no margin on any licence in the stack. A recommendation should be worth exactly as much as the reasoning behind it.
04
Leaving must be easy
Code, infrastructure, pipelines and documentation are yours throughout. If you want to bring it in house, we help you do it.
05
Own the incident
When something breaks on our watch we fix it first and apportion later. The post incident review is written, blameless and shared.
06
Recommend against ourselves
Roughly one enquiry in five ends with us saying the work does not need us. That is a good outcome, and it is why the referrals keep coming.
How we are set up
Two offices, one team
Client facing architecture and delivery leadership sit in London. The majority of engineering sits in Belgrade. Everyone works in the same time zone band and on the same board.
- London. Principal architects, delivery leads, commercial. Where discovery workshops and gate reviews usually happen.
- Belgrade. Platform, storefront, integration and quality engineering, plus the on call rota for the run service.
- Overlap. A minimum four hour working overlap with every client, and travel for discovery, gates and go live.
- On call. A follow the sun rota covering 24 hours a day, staffed by engineers who work on the platforms they support.
