For founders and product teams

Test your product with real users earlier.

T-NEX develops initial product versions and strengthens existing development teams. Reusable components and AI-assisted development support a fast start. You stay in control of priorities, scope and the next stages of growth.

Start with your technical lead or a defined product project

For founders, product owners and technical leaders developing a prototype further or seeking additional delivery capacity.

Both arrangements need clear ownership. Team extension may fit when your CTO leads architecture and quality. If the initial product still needs definition, we begin with user tasks, a clickable design and a bounded development project. The specific arrangement is set out in the proposal.

The right solutions for your team.

Overview

Build the first product around a testable user task

An MVP needs a complete path for its most important user task. Describe who starts, which inputs are needed and how that person knows the task is complete. Include missing information, cancellation and correction alongside the normal case.

Separate the initial scope from later possibilities. A second audience, more payment methods or extensive administration can be separate decisions. Scope, effort and schedule are agreed for the actual product.

Overview

Keep product decisions and development work visible

A shared backlog, regular demonstrations and clear acceptance criteria make progress assessable. Tickets describe expected behaviour. Changes are versioned and approved through the agreed review process.

Name a person who can resolve product questions. Extra developers cannot usefully accelerate work when product decisions are unavailable. Distributed teams also need agreed overlap hours, communication routes and a documentation language.

Overview

Agree usage rights and handover before development

The contract should distinguish newly developed results, existing components and third-party services. Section 31 of the German Copyright Act recognises different types and scopes of usage rights. Repository access alone therefore does not establish what you may modify, distribute or have another developer maintain later.

Agree the actual rights and the deliverables to be handed over. Depending on the project, these include source code, configuration, build and operating instructions, and external dependencies. This page does not replace those agreements.

Overview

Plan international work around actual access

Specify where each team works, which systems it needs and its access permissions. Development can often start with test data. Production data and customer access are included only when necessary and approved for the agreed scope.

Making personal data available to another company in a third country may constitute a transfer under Chapter V GDPR. EU hosting alone does not resolve this question. The contractual chain, data flow and necessary safeguards are assessed for the project.

Overview

Assess development experience through concrete functions

For AP Prüfservice, T-NEX developed a job platform with scheduling, mobile capture and a connection to existing business software. In the MONTEE customer project, the application connects work plans and feedback at an operator terminal. These examples show data, permissions, interfaces and handovers working together.

For your product, we select suitable technical patterns and check which components may actually be used. The references do not promise to reuse another customer’s application unchanged. What matters is a traceable route from your user task to the agreed application.

Overview

Choose a first package that supports a next decision

A suitable initial package provides a demonstrable result and clear handover. For a new application, this could be the main user journey. For an existing product, it could be an integration or a bounded functional area.

Evaluate result quality, collaboration and total effort, including your own coordination time. Include recurring services and maintenance in the cost assessment. You can then decide what stays in-house and where further support is useful.

FAQ

Questions about the solution

Can we begin without a CTO?

Yes. A project can begin with user tasks and an early design. Responsibility for technical decisions, acceptance and subsequent operation must be explicitly assigned for the project.

Does T-NEX offer a fixed MVP package?

The first product scope is defined individually. Functions, acceptance, schedule and fees are agreed in the project proposal. This page therefore does not state a universal package price or delivery date.

Do we automatically own the source code?

The agreement needs to specify your rights and the results to be handed over. New development, existing components and external services need to be clearly distinguished.

Can our own team take over later?

Plan the transition from the outset. It requires agreed access, documentation, traceable versions and a concrete handover scope. The necessary services and rights are recorded in the project agreement.
