Online Platform Development – Marketplace, Matching, Community

An online platform brings several sides together: providers and customers, members with one another, or guests and hosts. We build the technology behind it, and from running our own portals we know what matters in day-to-day operation.

Short & clear

An online platform is a web application on which multiple user groups interact – for example as a marketplace, matching, booking or community platform with user accounts, profiles, search, messaging and payment processing. Nano Concepts develops platforms from the first version through to operation and runs its own comparison portals with Tarifemaxx.de and KreditKoala.de. Platforms with user accounts and payment integration start in the Professional package from €8,000; we quote extensive marketplaces individually in the Enterprise package.

Online platform development with Nano Concepts

Anyone who wants an online platform built is usually not planning a single tool but a business model: a marketplace for providers and buyers, a matching platform for services, a booking portal or a community with a member area. What they all have in common is that several user groups come together and the platform takes care of finding, comparing, booking, paying and communicating for them. We develop these platforms as web applications that work on any device – with iOS and Android apps added on request.

01

Technically, a platform involves far more than a website: user accounts with different roles, profiles and listings, search and filter functions, a messaging system, review or approval processes, and payment processing that also handles commissions and payouts to providers. On top of that comes an admin area where you moderate content, manage users and analyze revenue. We plan the architecture so that the platform runs just as reliably with the first users as after successful growth into new regions or target groups.

02

Our experience comes not only from client projects such as an e-learning platform for more than 3,000 users but also from running our own: with Tarifemaxx.de and KreditKoala.de, we operate comparison portals whose marketing runs largely on automation. That is why, in platform development, we think about discoverability, load times and the processes in the background from the start. For launch, we often recommend a focused first version that delivers the core promise and then grows together with its users.

FAQ

Frequently asked questions about Online platform development

That depends on user groups, features and payment flows. We usually implement platforms with user accounts, search and payment integration in the Professional package from €8,000. We quote extensive marketplaces with many roles, apps and interfaces individually in the Enterprise package – the exact quote follows after the free initial consultation.

Depending on scope, a focused first version can go live within a few months. We plan in milestones so that you test with real users early and then expand in a targeted way. You receive a realistic schedule after the initial consultation.

Website builders are suitable for simple directories or member areas. As soon as roles, payment flows with commissions or custom matching logic are needed, a custom-built platform is usually the more viable solution. We discuss openly which route suits your project.

Common models are commissions per transaction, subscriptions, listing fees or premium memberships – also in combination. We integrate payment providers that can process payments between customers, providers and you as the operator. Please clarify separately which legal obligations your model triggers. This does not replace legal advice.

Technology alone does not bring users. We focus on discoverability in search engines, fast load times and simple registration; for campaigns, social media and SEO, we work with our partner agency LOMA DESIGN. It often makes sense to build up one side of the marketplace first, in a targeted way.

We develop platforms first as a responsive web application that works on any device. Apps for iOS and Android or a progressive web app can be built on the same interfaces as soon as usage justifies it.
