Custom Software
We build the software that is core to how your business competes — customer-facing web and mobile applications, internal platforms, SaaS products and marketplaces — and take responsibility for shipping it end-to-end with a small, senior team.
What this pillar covers
We build the software that is core to how your business competes — customer-facing web and mobile applications, internal platforms, SaaS products and marketplaces — and take responsibility for shipping it end-to-end with a small, senior team.
Who this is for
- Operations, product, engineering and revenue leaders who need a specific outcome — not a technology tour.
- Teams that already run a mix of platforms and need someone senior to make them work together.
- Organisations that have tried an internal build or a large SI and want a smaller, more accountable team.
What's on the table
Custom Software at 01Loop is a set of composable child services — a specific AI agent, a CRM implementation, a security assessment. Discovery decides the shape; a single call is usually enough to know whether we are the right fit.
What we deliver inside custom software.
Each capability is a scopable engagement. Combine two or three to hit a broader outcome.
Web application development
Product-grade web applications with a maintainable, typed foundation.
Mobile app development
Native-quality iOS and Android delivery with a shared, testable core.
SaaS product development
From first paying customer to a repeatable SaaS operating model.
Enterprise websites & portals
Marketing sites, partner portals and self-service experiences that convert.
Ecommerce development
Composable commerce for merchants outgrowing off-the-shelf themes.
From discovery to a workload that keeps improving.
- 012–4 wks
Discover
Map current systems, workflows and constraints; agree the custom software outcome and success criteria.
- 022–4 wks
Design
Architecture, data model, integrations and change plan. Trade-offs made explicit up-front.
- 034–20 wks
Deliver
A small senior custom software team ships in short increments you can inspect end-to-end.
- 04Ongoing
Operate
Optional managed run — SLAs matched to how critical the workload is.
- 05Ongoing
Optimise
Measurement, review and iteration. The loop closes and starts again.
How every custom software engagement runs.
- Send a senior practitioner to every discovery and delivery call.
- Publish a scope-of-work with success criteria before we quote.
- Ship in short, inspectable increments — never a big-bang reveal.
- Integrate with what you already run rather than replacing on principle.
- Flag risk the moment it surfaces, not at the last weekly.
- Hand over documentation and runbooks you can actually operate.
- Sell a platform we cannot deliver in production.
- Promise ROI numbers detached from a specific engagement.
- Farm the delivery to a junior team after signing.
- Claim certifications, partnerships or clients we have not verified.
- Bury change requests inside billable line items.
- Publish stock photos of people who never worked here.
