Software publisher — France

Software that brings closer what distance keeps apart.

YLYSYS designs and publishes its own software, built for real-world uses and international reach — from the very first line of code all the way to the people who use it.

The company

A software publisher, not a contractor.

YLYSYS is a French company based in the Yvelines, west of Paris. We do not build software to order : we design, publish and operate our own applications.

From the first idea to the hands of our users, we own every step. That independence lets us aim at one thing only : products that are useful, durable and true to how people actually work.

Proprietary design

We imagine and build our applications in-house, with a standing requirement for quality and longevity.

Real-world uses

Every product answers a concrete need — usually one the existing tools serve badly.

International reach

French roots, global ambition : our applications are multilingual and multi-currency by design.

Our applications

Products built end to end.

A portfolio of proprietary applications — open to as many people as possible, with advanced plans for demanding uses.

Our flagship product

Nine services in a single application.

YLYGO brings mobility, delivery and everyday services together under one verified identity. A subscriber who arrives for one use naturally finds the other eight : that is what makes a super-app rather than a bundle of separate services.

Ride sharing

Posting and searching for journeys, automatic matching with nearby drivers who are online, and price negotiation through offers and counter-offers.

Motorbike rides

The same journey flow adapted to two wheels : complete ride states from request to arrival, and a “Women only” option for verified female users.

Parcels & delivery

Two-sided parcel inspection, six-digit pickup and delivery codes, QR code, tracking number and live GPS location.

Currency exchange

Peer-to-peer matching, two-step cross validation, contact details revealed only once both sides agree. YLYGO never holds any funds.

YlyMarket

A marketplace for new and second-hand goods, with a native bridge to delivery : parcel tracking appears directly on the sale record.

YlyFood

Independent cooks and restaurants publish their dishes : a hygiene charter is mandatory, alongside dish of the day and anti-waste offers.

YlyJob

Local jobs and tradespeople across fourteen trades, search by radius, a completion code held by the client, and a downloadable proof of work.

YlyRent

Peer-to-peer rentals : accommodation, vehicles, construction equipment, event gear. Blurred address until the booking is agreed, photographic condition report.

Business & Enterprise

Businesses gather their members under one storefront with shared quotas ; companies open reserved offers to their employees.

Our approach

From the idea to a living product.

Publishing software is not only writing it. It is imagining it, building it, distributing it and supporting it over time. We carry all four stages ourselves.

Design

From intuition to specification : we frame the real need before writing a single line.

Development

Robust web and mobile applications, built to last and to evolve.

Publishing

Distribution, licensing and subscription plans : our products live under our own brand.

Operations

Infrastructure, updates and support : we keep every application alive, day after day.
