Custom software & prototyping

Testing an idea or building an application for everyday use? Olio develops functional prototypes, technical proofs of concept and custom software for startups and established businesses. We first clarify what you need to learn or achieve, then match scope and engineering quality to that goal. From validation and an MVP to production applications and continued development.

What we build as custom software

Typical projects are business applications replacing overgrown Excel landscapes, customer portals with self-service features, internal tools for planning, pricing, or scheduling, and systems that connect your existing software through clean APIs. We also integrate AI capabilities like document processing or assistants directly into the application. You don't get a customized standard product - you get software whose data model, permissions, and workflows match your business.

Replace spreadsheets or build a customer portal?

For an internal tool, we start with data sources, ownership and the steps currently lost between spreadsheets. A customer portal also needs clear boundaries between customers, roles and approvals: who can see which orders, documents or invoices? We assess whether existing software and integrations are sufficient or a custom application makes sense. Start with a bounded workflow, not a replacement for every system you run.

Prototypes and PoCs: test before investing

A functional prototype makes an idea usable: test workflows with real users, compare approaches and collect feedback. A proof of concept (PoC) tests a technical uncertainty, such as an integration, data pipeline or AI capability. Together we define the hypothesis and a measurable success criterion. Scope, timing and cost follow that question; a prototype does not automatically need a production system's budget or architecture.

Prototype, MVP or production application?

A prototype supports learning and is not automatically designed for ongoing operation. An MVP delivers a small, usable product scope for first real customers. A production application also needs to meet agreed requirements for security, reliability, permissions and maintainability. We clarify early whether the code should be carried forward or a deliberately limited experiment is the better choice.

Custom or off-the-shelf?

Standard software wins when your process is interchangeable - accounting, payroll, email. Custom software wins when the process is your competitive advantage, when per-seat license costs compound past the cost of owning a solution, or when you're hitting the limits of Excel, Access, or a legacy ERP add-on. In the first call we'll tell you honestly if a standard solution would be cheaper - it happens, and then we recommend it.

Scope and pricing around your project

We estimate your project based on learning goals, functionality, integrations and operating requirements. A limited prototype or PoC is a different engagement from an MVP or production platform. You get a clear estimate and milestones, without blanket minimum prices or artificial deadlines for experiments.

How we work

We start with compact scoping: understand processes, identify uncertainties and define the next valuable step. Short iterations give you working software to try and feed back on. Tests, architecture and documentation match the agreed use. After validation we can develop a production application, add features and integrations, or provide maintenance. You own the source code and can hand development over to your team.

Why Olio

You work directly with senior engineers and get honest recommendations: prototype, standard software or a custom application, whichever best supports your goal. For production use we plan data access, hosting, testing and operations together. EU hosting is available; data protection requirements need assessment of your actual project, not just its server location.

  • Functional prototypes and PoCs with clear learning goals
  • User feedback and technical validation before larger investment
  • MVPs and production applications matched to your needs
  • Source-code ownership and documented handover
  • Maintainable technologies such as TypeScript, Next.js, Python and PostgreSQL

Character persistence in image generation

Characters that stay recognisable across an AI storyboard

Storyboarder.ai turns a script into a finished storyboard. We built the character persistence: describe a character once, and they look the same in every panel. At a time when image generation could not do that on its own.

  • Character registry
  • Curated reference sets
  • Consistency across full boards

Frequently asked questions

What does custom software cost?

It depends on the goal and scope. A functional prototype or PoC is estimated around the question being tested; a production application also depends on integrations, roles, reliability and operating requirements. You get a transparent estimate with milestones before work starts. MVP prices are not a blanket minimum price for prototyping.

When is custom software worth it over standard software?

When the process is your competitive advantage, when standard solutions only fit with expensive workarounds, or when per-seat license costs over three to five years exceed the cost of owning a solution. For interchangeable processes like accounting, we'll honestly recommend the standard product.

How long does development take?

We agree on timing after scoping. A limited PoC, functional prototype and production platform have different requirements. We show working results regularly and decide together when a question is sufficiently validated or the application is ready for its agreed use.

Who owns the source code?

You do. You receive the complete source code, documentation, and all credentials. There are no license fees to us and no technical dependency - any competent team can take the software forward.

Can you integrate our existing systems?

Yes - that's part of almost every project: ERP and CRM systems, Salesforce, Microsoft 365, shop systems, or industry solutions connect via APIs. Where no interface exists, we find a clean path, from import pipelines to automation.

What happens after launch - who maintains the software?

Either works: we operate and maintain the application with defined response times, or your team takes over based on the documented handover. Many clients start with us operating and gradually take over themselves.

Can you turn a prototype into production software later?

Yes, when the agreed foundation supports it. We identify early what remains experimental and what can be carried forward. Before production use we review and extend testing, permissions, data processing and operations; sometimes a targeted rebuild is the better choice.

Which technologies do you build with?

TypeScript and Next.js on the frontend, Python or Node.js on the backend, PostgreSQL as the database, Docker for operations. Deliberately mainstream, maintainable technologies - so you can still hire developers for them in five years.

How do you address data protection?

We clarify data types, access, deletion and hosting for your use case and implement agreed technical measures. EU hosting is available. The actual use and your organizational processes also determine which data protection obligations need to be met.

Do you work with clients outside Germany?

Yes. We work remotely across the EU in English and German. Contracts, invoicing, and data processing agreements follow EU law, which keeps procurement simple for European companies.

Can you take over an existing codebase instead of starting fresh?

Often, yes. We audit the existing code first and give you an honest assessment: continue, refactor step by step, or rebuild the critical path. A rescue is frequently cheaper than a rewrite - but not always, and we'll tell you which case you're in.
