Deltaworx is the Belgian staffing agency that works exclusively with students. Founded in 2012 by Jeroen Poels, it has clubhouses in Antwerp, Ghent and Brussels and places student workers with companies in sectors such as logistics, manufacturing, retail and office support. On its website, Deltaworx lists more than 57,733 students and more than 1,576 companies. In 2026, Deltaworx joined forces with Beyond Mars, the brand for hospitality, events and brand activations. In their own words, together they form one of the strongest Belgian groups in flexible employment, filling more than 80,000 flexible vacancies a year. TRON Group has been a long-standing technology partner to Deltaworx since 2016. We work on the iOS and Android app, the custom back office and scheduling system and the jobs platform, we provide support and managed IT, and we secure the team's workstations. Beyond Mars runs its jobs platform on that same foundation. Below you can read how the platform grew with the business, why it was built for multiple brands, and the role security, governance and AI advice play today.
Starting point
The challenge
A student staffing agency runs on speed. A company asks for extra hands today and ideally wants someone on the shop floor this week. Deltaworx promises students contact within 24 hours of registering, and their first shift can be the same week. That only works if profiles, intake interviews, assignments, shifts and hours come together smoothly, and if students can handle much of it themselves from their phones. Then there are Belgian regulations. Today a student worker may work 650 hours per calendar year at reduced social security contributions, a student employment contract must be in writing by the start of work at the latest, and every placement requires a Dimona declaration. Software for this sector has to reflect that reality: speed for students and companies, and care with contracts and data. And because the entire business model runs on students' personal data, security is never an afterthought. So this was about more than an app. Deltaworx needed a digital foundation that would grow with the number of students and regions, and stay secure. That foundation later proved strong enough to support a second brand as well.
The group

Deltaworx and Beyond Mars each speak to their own audience, with their own style and tone. Technically they share one jobs platform: a distinct look for each brand, with the same foundation beneath the surface.

How we tackled it
Our approach
App and back office as a single system
Since 2016 we have been working on the Deltaworx app for iOS and Android, which launched in the App Store and Google Play in summer 2017. Students use it to create their profile and respond to jobs and shifts. Underneath sits the custom back office where the Deltaworx team manages candidates, assignments and scheduling. Together they work as a single system, so whatever a student does on their phone is immediately visible to the consultant.
Growing with the business
As Deltaworx expanded into more regions, the platform grew with it. Over the years we added, among other things, self-scheduled intake interviews, virtual intakes, statistics on hours worked and contracts, downloadable job sheets, Sign in with Apple, a calendar and a new design. In 2019 we moved the app to a new API architecture so we could roll out new features faster and more reliably. Today students use the app to sign up for shifts, sign contracts, log their hours and see when they will be paid.
One jobs platform for multiple brands
The jobs platform is set up as a single codebase that shows each brand with its own branding, content and contact details. Vacancies are published with structured data for Google Jobs, candidates apply online in one click, accounts are protected with two-factor authentication and email verification, and candidates can delete their own accounts. That is how the Beyond Mars jobs platform runs on the same foundation: its own look and feel, but no second system.
Security and governance for the group
A staffing agency processes identity documents, contracts and payroll data. So we secure the team's workstations with centrally managed endpoint security and guide the group on security governance: who has access to which data, what agreements apply, how an incident is reported, and how that policy stays current now that the group has expanded with a second brand.
AI with a clear policy
On AI, we work with the group to find where it genuinely saves consultants time, and where it doesn't. AI that recruits candidates, filters CVs or assesses candidates falls into the high-risk category under the EU AI Act. That is why we advise keeping the decision with people: AI supports the consultants, but it does not select candidates or reject them.
The big picture
The solution
Since 2016, Deltaworx has worked on a digital platform that has grown with the company, and Beyond Mars now runs on it too. The custom back office and scheduling system form the core. Around it sit the iOS and Android app, which students use to manage their profile, shifts, contracts and hours, and the jobs platform that serves two brands from a single codebase: Deltaworx for students and young talent, Beyond Mars for hospitality, events and brand activations. Each brand keeps its own identity, but technically they share the same foundation, security and updates. Around that platform, TRON Group provides support and managed IT, endpoint security for the workstations, security governance for the group and advice on where AI adds value. For the back office, app, jobs platform, security and AI advice, the group works with one partner that knows the platform's history.
The app
In the App Store and Google Play since 2017.
Students create their profile, schedule their intake, sign up for jobs and shifts and keep track of their contracts and hours. Over the years the app has gained features such as virtual intakes, a calendar and a new design.
What it delivers
The results
- The same partner for Deltaworx's app, back office and jobs platform
- Since 2016
- Deltaworx and Beyond Mars on one codebase, each with its own branding
- 2 brands
- One app for students, in both stores since 2017
- iOS + Android
- Software, security, AI advice and IT management under one roof
- 1 partner
The most important result is continuity. Since 2016, Deltaworx has kept building with the same partner, one that knows the platform and renews it step by step, from a new API architecture to a jobs platform for multiple brands. That is why a second brand like Beyond Mars can run on the same jobs platform without needing a second system. Students work with one app, consultants with one back office, and management with one point of contact who looks at software, security and advice together. With, by its own figures, more than 80,000 flexible vacancies filled each year, a great deal of the group's business rests on that foundation.
