AI agents & assistants
Task-scoped agents with tool access, guardrails, and a human in the loop wherever the cost of being wrong is high.
LinkGro Technologies
Software, AI, and Products That Ship
We design and build web platforms, mobile apps, and AI systems — and we run our own products, so we ship under the same constraints our clients do.
What we do
Four groups, every layer of your stack
From a first release through to modernising a platform that has outgrown itself — and the AI and data work that increasingly sits across both.
AI engineering
AI that does work, not demos
Language models become useful when they are wired into real data and real workflows. That wiring is the engineering.
RAG & knowledge systems
Retrieval over your own documents and data, with citations, so answers can be checked rather than trusted.
Workflow automation
Queues, schedulers, and event pipelines that move work between systems without anyone copying fields by hand.
LLM integration
Model selection, prompt and context design, caching, evaluation, and cost control on the hot paths.
How we work
Pick the shape that fits the problem
Fixed scope when the requirements are known, a dedicated team when they are still moving.
Fixed-scope project
A defined deliverable at a defined price. Best when requirements are settled and the surface is well understood.
- Milestone billing
- Written acceptance criteria
- Fixed timeline
Dedicated team
Engineers embedded with yours, working your board and your standards. Best for ongoing product work.
- Monthly rolling
- Your tooling and process
- Scale up or down
Consulting & audit
A read on architecture, security, or performance, delivered as findings you can act on without us.
- Fixed engagement
- Written report
- No lock-in
Why us
What working with us is actually like
Each of these has cost us work at some point. We would rather lose it up front than halfway through.
You own the code from the first commit
It lives in your repository, or is transferred at handover. No licence retained, no escrow, no dependency on us to keep running.
We will tell you not to build it
If the thing you asked for is not the thing that solves the problem, that goes in the discovery report — even when the smaller scope is worth less to us.
Estimates carry their assumptions
A number without the assumptions behind it is a guess with a decimal point. Ours name what would change them.
No offshore relay
The people in the kickoff are the people writing the code. Nothing is passed to a team you have not met.
Stack

Chosen for maintainability over novelty. Almost everything here runs in our own production, not just our clients’.

Industries
Where we have built
Domain shapes the constraints more than the stack does.
Resources
Notes from work we have actually done
Written when something took longer than it should have, or when the answer online was wrong.
Deployment
Deploying Next.js on shared hosting: what actually works
Shared hosting can run Next.js, but not the way the docs assume. What Passenger expects, why the build succeeds and the app still will not boot, and the monorepo trap.
7 min readArchitecture
Multi-tenancy before your second customer
Tenant isolation is a data-model decision, not a permissions one. Why retrofitting it means touching every query, and the guardrail that makes it stick.
6 min readEngagement
What actually drives the cost of a software project
Why the same brief gets quotes that differ by 4×, which variables move the number most, and what to ask for so the estimates are comparable.
6 min readQuestions
What clients ask first
If your question is not here, it is probably worth a call rather than a paragraph.
From a single well-defined release through to a multi-quarter platform build. If a project is too small to justify our involvement we will say so rather than pad it.
Still have a question? Talk to the team
Tell us what you are building.
A short call is usually enough to say whether we are the right team, and what it would take.
- No obligation
- You own the code
- Written scope before work
