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.

YLYGO
The super-app for mobility and everyday services.
Fourteen services in a single application : ride sharing, motorbike rides, parcels and delivery, a marketplace, home-cooked meals, local jobs, rentals, events, messaging, money management, live streams and videos, a calendar, email, games and professional plans. The principle is simple and rare : zero commission on exchanges between users. Providers subscribe and keep 100 % of what they earn.
A remote construction management platform built for diaspora communities building in their country of origin : progress tracking, full transparency on spending, and direct contact with the people on site.

Roadmap
What comes next
New products in preparation.
Our portfolio keeps growing. Other applications are already in the works for new uses. Would you like to hear about launches ?
YLYGO brings mobility, delivery and everyday services together under one verified identity. A subscriber who arrives for one use naturally finds the other thirteen : 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.
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.
YlyEvent
Publish an event, book a seat: a QR-code ticket checked at the door — payment is settled with the organiser.
YlyChat
Messages, photos, videos, voice notes, documents and location; audio and video calls; 24-hour ephemeral statuses.
YlyPay
Your account book: budgets, provisions, debts, shared pots, tontines, business spaces and a financial-health score. More on ylypay.com.
YlyLive
Sell, show and gather live: shop, event or creation, 30-day replays, videos and series, free or paid access, ads. More on ylylive.com.
YlyPlanning
Your calendar: events, tasks, notes, reminders, date polls, three-level sharing — with your rides, deliveries and due dates added automatically.
YlyMail
Your mailboxes (IMAP, Microsoft) read from the app: only headers are kept, never the message bodies.
YlyGames
Draughts, Ludo and Chess: two players on one phone, online against another player, or against the computer.
Business & Enterprise
Businesses gather their members under one storefront with shared quotas ; companies open reserved offers to their employees.

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.
01
Design
From intuition to specification : we frame the real need before writing a single line.
02
Development
Robust web and mobile applications, built to last and to evolve.
03
Publishing
Distribution, licensing and subscription plans : our products live under our own brand.
04
Operations
Infrastructure, updates and support : we keep every application alive, day after day.
