Custom software & enterprise architecture

Custom software, built like it has to hold.

From a booking tool for a growing business to a platform that has to scale, the same senior engineering sits behind every build. Backed by 25+ years of enterprise architecture experience in retail and financial services.

One standard, sized to your project

Growing businesses

Business applications & automation

  • Booking, inventory, invoicing, and internal workflow tools
  • Spreadsheets and paper processes replaced with software that fits how you actually work
  • Focused builds that move quickly and are made to grow with you
Scale-ups & enterprise

Platforms & architecture

  • Commerce, financial-services, and other high-stakes systems
  • Architecture reviews, performance work, and modernization of what you already run
  • Senior architecture leadership without the agency layers

Same people. Same standards. Different size.

The discipline behind a first app is the discipline behind a platform — so you never have to choose between a small build done right and a big one done well.

A–02

What we build

01Commerce & retail

Platforms that sell

Headless and composable commerce, order management, product information, marketplace integrations, and in-store technology for multi-channel retailers.

02Financial services

Systems where accuracy matters

Online banking, insurance, and credit-risk applications, where reliability, auditability, and careful change management come first.

03Modernization & cloud

Moving forward without stopping the business

Legacy migrations, cloud architecture, and platform engineering, plus the standards and governance that keep the result maintainable.

04Applied AI

AI that works inside a real organization

Adopting generative and agentic AI responsibly: choosing where to start, integrating with existing systems, and governing access and risk as use grows.

A–03

The experience behind the team

Retail

Digital platform for a multi-brand retailer

Led architecture and engineering across headless commerce, order management, product information, and social-commerce and marketplace integrations, and set the architecture standards and governance used across the enterprise.

Retail

Marketplaces and in-store technology

Delivered integrations with major global marketplaces for several consumer brands, and piloted a mobile point-of-sale solution in physical stores in Europe and North America.

Banking

Online banking for a European retail bank

Designed and built the application, led the team through delivery, then moved design and development to a new offshore team without interrupting the work.

Investment banking

Legacy modernization and credit risk

Migrated legacy applications for a UK investment bank and delivered a strategic credit-risk application, leading global teams of 25+ engineers using Agile delivery.

Insurance

Large-scale systems integration

Delivered a multi-year integration program for a major insurer, with round-the-clock production support for critical consumer-facing applications.

Enterprise architecture

Standards that teams actually follow

Built architecture frameworks, patterns, and review processes used across an enterprise's applications, and led the senior architects responsible for technical solution decisions.

Why work with SPAN Labs

Senior from the start

The people scoping it have run it

Our advisor has led delivery teams of 30+ across several time zones. The same experience goes into scoping and reviewing your project, not only into the sales conversation.

Scoped to fit

No fixed packages

Every engagement is shaped around the problem, and most begin with a short architecture review or discovery sprint so the approach is agreed before a larger build.

Rigor by default

Standards, not ceremony

We bring the architecture standards and review practices used on large enterprise programs, applied at the size your project needs.

Transparency

Decisions you can read

Significant technical choices are written down with the options considered and the trade-offs, so you can see why, not just what.

A–05

What “AI-accelerated” actually means

Where it speeds us up

The repetitive work

  • Scaffolding, boilerplate, and first drafts of routine code
  • Test generation and wider test coverage
  • Drafting migrations and refactors for an engineer to review
  • Documentation and getting up to speed on unfamiliar legacy code
Where people stay in charge

The decisions that matter

  • Architecture, data modelling, and technology choices
  • Security-sensitive and business-critical logic
  • Review of every change by a senior engineer before it ships
Your data

Handled with care

Confidential data, credentials, and production records stay out of AI tools. If your company has a policy on AI use, we work within it — just tell us at the start.

What you get

Speed without lower standards

Faster first versions, more testing, and fewer surprises. The savings show up in the schedule, not in what we're willing to ship.

A trusted network, when it's needed

Senior partners · brought in as projects require

For larger builds, SPAN Labs draws on a small, vetted network of senior architects and engineers — each with their own enterprise-grade track record. You still work with one team throughout; the network scales quietly behind the scope.

A–07

When people call us

Small business

“We run on spreadsheets and WhatsApp.”

We turn the scattered tools into one simple system your team actually uses — bookings, orders, invoices, whatever your day runs on.

Enterprise

“We need to modernize without stopping the business.”

We map what you have, fix the riskiest parts first, and move you forward in steps — no risky all-at-once rewrite.

Growing company

“Our app is slowing down as we grow.”

We find what's actually holding it back and fix that, instead of rebuilding everything from scratch.

Any size

“The person who built it left, and nobody knows how it works.”

We make sense of it, document it, and put it on a footing you can rely on.

Early stage

“We have an idea, but what do we build first?”

We help you choose the smallest version worth building, then build it properly the first time.

Mid-size company

“We want a second opinion before we commit.”

An independent, senior review of the plan, the risks, and the cost — before you spend.

A–08

How engagements begin

Architecture review

A senior second opinion

For a system you already run, or a plan you're about to commit to.

  • Review of the architecture, scalability, security, and operational risks
  • Written findings with prioritized, practical recommendations
  • A walkthrough call to discuss the findings and next steps
  • Everything produced is yours to keep
2-week discovery sprint

From idea to a plan you can act on

For a new product or tool where the first question is what to build.

  • Workshops to pin down goals, users, and the workflows that matter most
  • The smallest valuable first version, defined and prioritized
  • Architecture outline, technology choices, and key risks
  • A phased delivery plan with an estimate range
