Marketplace software · Turnkey & bespoke
The marketplace solution for launching your own platform
Sales, rental, matchmaking or classified ads: Medialem combines proven marketplace software with a team that builds your bespoke features. You focus on your business, we handle all the technical work.
One software, every model
A solution for every marketplace model
Thanks to its modular architecture, the Medialem platform handles every marketplace workflow: multi-vendor e-commerce, online booking, directories, ads with subscriptions or advanced matchmaking processes.
Product marketplace
Multi-vendor, physical or digital goods: catalogue, cart, payment, commissions and delivery handled end to end. Like Amazon or Etsy.
Rental & booking
Availability calendar, time slots, secure prepayment: built for renting goods or booking services. Like Airbnb or Getaround.
Matchmaking platform
Buyers post what they need, providers answer: automatic matching, quotes, comparison and secure payment.
Classified ads site
Transactions happen off-platform: monetise through seller subscriptions and promotion options. Like leboncoin.

Frequently asked
Everything about the marketplace solution
What is the Medialem solution and how does it work?
Medialem is a solution for launching matchmaking platforms. It combines:
- A WordPress showcase site so you can manage your content and your SEO on your own.
- A marketplace platform (Python/ReactJS) for the advanced features: listings, orders and bookings, payments, multi-vendor management, messaging, reviews and ratings.
You drive all of it from one intuitive admin interface.
What kind of projects is the solution suited to?
Any multi-vendor marketplace where suppliers offer products or services to buyers: online sales of new or second-hand goods, a rental or booking platform, services between individuals or professionals, B2B/B2C/C2C, a monetised classified ads site.
It is not suited to single-vendor shops or plain showcase sites.
Do I need technical skills, or to hire a developer?
No. You drive everything from the admin interface: categories, ad characteristics, commissions, subscriptions, moderation, users, orders, statistics. Medialem handles development, hosting and maintenance, trains you during the first month and provides ongoing support. If you do hire, it will be on the business and marketing side.
How long does it take to launch a marketplace?
From a few days (setup and adaptation to your brand guidelines) to a few weeks for a more advanced design, and a few months if your project needs bespoke feature development.
Can I use my own design and brand guidelines?
Yes. We start from a template and adapt it to your brand guidelines at no extra cost. A fully bespoke design is available on quotation.
How much does the Medialem marketplace solution cost?
The cost depends on the type of marketplace and the features you want. Our rates are all-inclusive, from development to support, with no setup fee and no hidden costs. See the pricing page or contact us for a tailored quote.
How do payments, commissions and seller payouts work?
We integrate payment providers built for marketplaces (Stripe Connect, Mangopay). Everything is automated: collection on behalf of third parties, commission calculation, seller payouts, refunds, KYC. Nothing is required from you, apart from edge cases such as disputes.
How are security and scaling handled?
Secure infrastructure, hosting inside the European Union, sound application practices, monitoring and performance tuning. The platform scales with your volume of ads and users, and stays tunable as your business grows.
