Replace the legacy stack with something built for how you run today.
One system, one source of truth, one vendor on the hook for it. We take the patchwork of disconnected apps and the system that’s been quietly holding back the business, and build a single platform around how your team actually works.
What this means in practice
Legacy systems rarely fail loudly. Far more often they slow a business down quietly — the bespoke tool nobody's touched in years that runs payroll fine but blocks every new feature; the SaaS suite the team has outgrown and now works around; the knot of three or four apps that, between them, almost cover the job. Modernisation is about replacing what genuinely needs replacing, while leaving alone what still works.
A modernisation engagement starts with a discovery phase: we map the current systems, the workflows they support, and the bits of institutional knowledge that live in people's heads. From there we agree what gets rebuilt, what stays, and what gets retired. Migrations run in phases with the old and new systems in parallel wherever the data model allows it, and with rehearsed cutovers so go-live day is a non-event rather than a leap.
Where the right answer is consolidation — folding three SaaS tools into one bespoke platform — we build that. Where the right answer is a fresh front-end on top of stable back-end logic, we build that. Either way the engagement closes with documentation and runbooks your team can use long after handover.
Who this is for
- Operators tied to an in-house tool nobody’s touched in years
- Teams who’ve outgrown an off-the-shelf platform but can’t walk away mid-flight
- Businesses running on a tangle of SaaS that nobody can fully map
- Owners who want to keep the workflow but lose the maintenance tax
Industries this service fits best
The sectors where this offering tends to be most relevant — not a claim of completed work in each. The Potter Sanctuary is our first shipped engagement (in Custom Platforms); other sectors below are where this service translates cleanly.
What this service typically includes
- Discovery-led replacements of legacy in-house systems
- Data migration with reconciliation and rollback safety
- Phased cutovers running new + old in parallel
- Consolidations of multiple SaaS tools into one platform
- Modernised front-ends on top of stable back-end logic
- Documentation and runbooks the team can actually use
How we work
One person, end to end. Brief to launch in roughly four weeks. Code you own from day one. The full breakdown lives on the homepage process section.
