What we build
Six services.
One engineering standard.
Every engagement runs through the same architecture review, security baseline and delivery cadence.

Custom Software
SaaS platforms, CRM and ERP systems built to your process, on codebases another team could pick up tomorrow.

Specialisms
Sectors we already understand.
Discovery starts from your regulations and workflows instead of a blank page — so less of the budget is spent explaining your own business to us.
Financial Services
FCA-compliant websites for mortgage and protection advisers — plus adviser CRM, structured fact-find and case pipelines built around how UK advisers actually work.
Healthcare
Patient intake, referral routing and clinical records, with UK data residency and consent handling agreed before build starts.
Construction
Procurement, subcontractor scheduling and live cost tracking, so project margin is visible during the job rather than after it.
Recruitment
Candidate rediscovery and semantic search across the database you already own, without forcing an ATS migration.
How we work
Four phases. Fixed checkpoints.
Each phase ends with something you can review — a document, a prototype, a running environment.
01
Discovery
We map the process, the data and the constraints. You get a written scope and a fixed estimate before anyone opens an editor.
Ends with · Technical scope
02
Architecture
Data model, integrations, security and hosting plan — reviewed with your team and signed off before build starts.
Ends with · Architecture document
03
Build
Two-week sprints against a staging environment you can open from week one. A working demo every fortnight.
Ends with · Working software
04
Launch & Support
Go-live, monitoring, documentation and handover. We stay on support while your team takes ownership.
Ends with · Live systemSelected work
Measured after launch.
Client names withheld by agreement. Named references available during discovery.

Why Plinium
Built to be inherited.
The real test of a system is what happens two years after launch, when a different team is maintaining it and the business has moved on. We build for that day, not for handover day.
Start a conversationSenior engineers onlyNo juniors learning on your budget. The person scoping the work is the person building it.
Architecture that scalesSized for the load you will have in two years, not just the load on launch day.
Full ownershipYour repository, your hosting accounts, your code. Complete transfer on final payment.
We stay after launchDocumentation, monitoring and a support window included. Retainer optional, never required.
Questions
Before you get in touch.
How quickly can you start?
Discovery usually begins within one to two weeks of an agreed scope. Smaller automation and website projects often start sooner.
How do you price work?
Fixed price per phase, quoted after discovery. You approve the scope and the number before build starts. Changes go through a written variation, never a surprise invoice.
Do we own the code?
Yes. Full IP transfer on final payment, delivered in your own repository with deployment documentation. No lock-in, no licence back to us.
Where is our data hosted?
Your choice. UK and EU regions are routine for us, and we sign DPAs as standard.
Do you work with our existing systems?
Usually, yes. We integrate with most CRMs, ATS platforms and databases over API. Where no API exists, we assess the options during discovery.
Start here
Tell us what's slowing the business down.
Forty-five minutes with a senior engineer, not a salesperson. You leave with an architecture opinion and a realistic estimate — whether or not you go ahead with us.
