Who we help
Built for teams whose software can’t fail.
Most clients come to us at one of four moments. Choose the one that sounds like you to see exactly how we help.
Owners, MDs and operations leaders
Take back control of the system your business depends on.
Your core application was built years ago, often on .NET Framework, by a developer or agency who has since moved on. It still works, but every change feels risky and nobody fully understands it any more.
Sound familiar?
- Nobody understands the code any more.
- Every fix seems to break something else.
- We’re on an unsupported framework and worried about security.
- Releases are manual, slow and stressful.
How we help
- Take over and stabilise. Review, document and fix what matters most first.
- Keep it safe. Monitoring, security patches and a support retainer.
- Modernise step by step. Move to .NET 10 and Azure without a risky big-bang rewrite.
The outcomeA stable, supported system and a clear plan forward.
Founders, product owners and start-ups
Turn your idea into a product that’s ready to scale.
You have a clear vision and need a senior engineering partner who can make the architecture decisions, build a first release quickly, and lay foundations you won’t have to throw away.
Sound familiar?
- We need an MVP that won’t need rewriting in a year.
- We don’t have a CTO to make the technical calls.
- Multi-tenancy, billing, security: where do we start?
- Our last agency over-promised and under-delivered.
How we help
- Scope it properly. Discovery workshops ending in a written plan and estimate.
- Build the first release. .NET with React or Blazor, demoed every two weeks.
- Design for SaaS. Multi-tenant Azure architecture, auth, billing and AI features.
The outcomeA launch-ready product, built on foundations that scale.
Software houses, agencies and IT teams
Senior .NET engineers on your team within days, not months.
Your backlog is growing faster than your team, or you’ve won work that needs specialist .NET and Azure skills. We plug in alongside your developers or deliver under your brand.
Sound familiar?
- Hiring a senior developer is taking months.
- We’ve won a .NET project we can’t staff.
- A project is in trouble and needs an experienced pair of hands.
- We need an architecture review before we commit.
How we help
- Team extension. Senior engineers who work in your tools and ceremonies.
- White-label delivery. We build, you own the client relationship, all under NDA.
- Rescue and review. Architecture reviews, code audits and turnaround of troubled projects.
The outcomeSenior capacity on demand, with no recruitment risk.
Operations, finance and service teams
Replace the spreadsheets and re-keying with one system.
Critical work lives in spreadsheets, email chains and shared drives. Information is typed in twice, reports take days, and nobody can see the whole picture. Off-the-shelf tools never quite fit.
Sound familiar?
- We copy the same data between three systems.
- Month-end reporting takes the team days.
- Approvals get lost in email.
- Errors creep in and nobody notices until it’s too late.
How we help
- Internal tools and portals. Built around exactly how your team works.
- Connect your systems. Integrations so data is entered once and flows everywhere.
- Automate with AI. Extract data from emails and PDFs, with human review built in.
The outcomeHours saved every week and one source of truth.

Why Vinci
The control of your own team. The expertise of a specialist.
Off-the-shelf suits standard needs like accounting or email. Where your processes set you apart, a specialist partner costs less over time and keeps you in control.
| Consideration | Off-the-shelf software | Offshore outsourcing | Vinci Technologies |
|---|---|---|---|
| Fit to your processes | Your team adapts to the product | Depends on how well the brief is written | Designed around your workflows |
| Who does the work | Vendor’s roadmap team | Often junior, frequently rotated | Senior engineers, start to finish |
| Ownership and control | Licensed; the vendor controls the roadmap | Code access and ownership can be unclear | You own the code, data and cloud accounts |
| Cost over time | Per-user fees that rise as you grow | Low day rates, high management overhead | Written estimates and predictable retainers |
| Communication | Support tickets and help centres | Time-zone gaps and multiple handovers | Direct access, UK business hours |
| After launch | Tied to the vendor’s priorities | Frequent team turnover | The team that builds it supports it |

How to tell when an ageing business application has become a risk, and what to do about it.
Read article →Fixed Price, Retainer or Hourly: Choosing the Right Engagement Model
A clear comparison of the three ways to buy software development and support, and when each works best.
Read article →Can you take over software someone else built?
Yes. Much of our work is taking over applications whose original developer or agency has moved on. We start with a code and infrastructure review, stabilise and document the system, and only then start improving it.
Who will actually do the work?
Senior engineers only. The engineer you meet on the first call leads your work, writes and reviews the code, and stays with you after launch. There is no hand-off to a junior team you never meet.
How much does a project cost?
It depends on scope. After a free discovery call we send a written estimate. Small fixes can be billed hourly, larger builds are usually fixed-price by milestone, and ongoing support suits a monthly retainer.
Do I own the code?
Yes. Once paid, all source code, documentation and infrastructure belong to you. Everything lives in your own repository and cloud account from day one.
Can you work inside our team or under our brand?
Yes. Software companies and agencies use us for senior .NET capacity, either alongside their own developers or as a white-label delivery partner under NDA.
Do you only work with .NET?
.NET and C# are our core expertise, and we work across the full stack, including React, Angular, Blazor, TypeScript, SQL Server, PostgreSQL, Neo4j, Redis, RabbitMQ, SignalR, Azure and modern DevOps tooling.
How quickly can you start?
Urgent production issues can usually be assessed within one business day. New projects typically start within one to two weeks.
