What We're Capable Of

SPAWN.LONDON is a London-based, AI-accelerated software agency. We build custom software and apps, provide AI consultancy, transformation and training, commercially recover distressed projects and startups, reverse engineer legacy hardware and code, and design custom AI and secure systems — from board-level strategy down to bit-level engineering.

Software & App Development

From bespoke SaaS replacements to funded startup POCs and MVPs - cloud-native architectures engineered to grow from first release to millions of users.

What We Build

  • Custom software - bespoke systems that replace off-the-shelf SaaS and spreadsheet sprawl.
  • POCs & MVPs - proof-of-concept and minimum viable product delivery for funded startups.
  • Multi-tenant SaaS platforms - complete products with billing, subscriptions and role-based access.
  • Web platforms & portals - consumer and business web applications, e-commerce and payments.
  • APIs & integrations - REST APIs, Stripe, webhooks and third-party system integration.

How We Build It

  • Cloud-native & auto-scaling - Microsoft Azure serverless and containerised architectures.
  • AI-accelerated delivery - production-ready code at pace, with human-controlled architecture, security, review and testing.
  • Specification-led - requirements engineering, user stories, target architecture and delivery roadmaps.
  • Secure by design - authentication, MFA, role-based access, tenant isolation and audit trails.
  • Ongoing maintenance - monitoring, support and growth built in from day one.

Rapid Prototyping

From idea to working prototype in days, not quarters - de-risking the decision before you commit serious budget.

Distressed Project & Startup Recovery

Commercially recovering projects before it's too late - with a clear-eyed view of remaining budget, targets and stakeholder expectations.

Distressed Projects

We analyse the existing codebase, establish what genuinely works, then either strengthen your team or propose taking over delivery outright — recovery planned around the project's real commercial position, not an idealised restart.

Distressed Startups

When a startup's product or engineering has run off course — burn outpacing progress, roadmap drifting from the market — we refocus the build on what investors and customers actually need, within the runway that remains.

Legacy Hardware & Code

Old systems, old code, no documentation? We reverse engineer legacy hardware and software for automation and system control — tracing legacy code, reconciling behaviour against original specifications and performing oscilloscope-led, bit-level diagnostics.

The Spawn AI Laboratory

Our own on-premises AI laboratory: develop secure software and analyse confidential data entirely offline - your data never touches the internet.

The lab runs a range of local models and can hold your confidential material in a private RAG (Retrieval-Augmented Generation) setup: your documents, drawings and data are indexed privately so the AI answers are grounded in your material — without that material ever training a public model, being shared with a third party, or leaving the lab. Ideal for commercial-in-confidence work, defence and security, reverse engineering legacy systems, and modern computation or AI-assisted software writing.

Offline Core

Our standard laboratory machines are air-gapped — they never connect to the internet. Models run entirely locally, so analysis, generation and computation happen on hardware with no route out.

Air-GappedLocal ModelsZero Egress

Internet-Isolated Machines

Where a task genuinely needs the web — research, package retrieval, external services — separate machines handle it. They can connect to the internet but remain physically disconnected from the systems holding your data.

Physically SeparatedTask-Only AccessNo Data Path

Built for You, Then Wiped

For the most sensitive engagements we commission machines specifically for your project and securely wipe them when it completes — we retain none of your client data afterwards.

Project-DedicatedSecure WipeZero Retention

Or Built at Your Premises

Prefer it never leaves your building at all? We design, build and commission the same laboratory setup on your site — then train your team to run it, with ongoing support if you want it.

How quickly can SPAWN.LONDON build a prototype?

Working proof-of-concept software can be delivered in days to weeks. The core of our ForgeBOS platform - subscriptions, billing and CRM - reached functional first release in around a week, using AI-accelerated development with architecture, security and code review under human control. We also build hardware and embedded prototypes, from Raspberry Pi rigs to custom circuit boards.

Does SPAWN.LONDON provide AI training and talks?

Yes. We speak at events and in the workplace, and deliver AI training programmes. Engagements start with a scope and analysis of what your teams currently do, identify appropriate uses of AI respecting ISO standards, security and client confidentiality, present recommendations to the board or management, and then help implement the changes including the systems and training required.

Can SPAWN.LONDON recover a failing software project?

Yes. Distressed project recovery is a specialism: we analyse the existing codebase, then either work alongside your team or propose taking over delivery, always with a clear view of remaining budget, targets and stakeholder expectations. We also recover distressed startups whose product or engineering has run off course.

Can SPAWN.LONDON work with legacy hardware and old code?

Yes. We reverse engineer legacy systems for automation and system control - reading and tracing legacy code, reconciling behaviour against original specifications, and performing oscilloscope-led, bit-level diagnostics where needed, as demonstrated in our Safran aerospace test-equipment recovery.

Does SPAWN.LONDON build on-premises AI systems?

Yes. We design and build private on-premises AI and hybrid autonomous on-prem / online systems, where models run on hardware you control and sensitive data never leaves the building - with RAG, model orchestration and controlled online interaction where reach is needed.

What is the SPAWN.LONDON on-premises AI laboratory?

The Spawn AI Laboratory is our own on-premises facility for developing secure software and analysing data with AI entirely offline - nothing ever touches the internet. It runs a range of local models and can hold your confidential data in a private RAG setup. The lab operates in tiers: air-gapped offline machines; separate internet-capable machines that are physically disconnected from your data; and machines built specifically for your project and securely wiped afterwards, so we retain none of your data. We can also build the same setup at your premises and train your team to run it.

Can SPAWN.LONDON analyse confidential or defence data with AI without it going online?

Yes. Our offline on-premises AI laboratory is designed for exactly this: commercial-in-confidence work, defence and security material, reverse engineering of legacy systems, and modern computation or AI-assisted software writing - all processed locally on machines that never connect to the internet, with project machines wiped after completion.
