Before Welii, Vincent was in charge of supporting a startup CEO in structuring the company administratively and financially until 2020, going through a $10m Series A and recruiting over 35+ people.

As a CFO, he discovered that in a fast-growing environment the management of SaaS vendors has become very complex and time-consuming. The problem was twofold: buying software is an uncomfortable experience given the opacity of the market, and maintaining an inventory of these hundreds of suppliers is a long and painful process.

To help a whole ecosystem address these challenges, he wanted to create a solution that allows its clients to negotiate the best deals, faster.

Otherwise, when he's not at work he's always looking for vinyl in the record shops of Paris or on the track for a jog.

Jean-Guillaume graduated with a Masters' degree from EPITECH in 2017. During his studies there, he got the opportunity to work from their early days withing several successful startups such as Printic (acq.), Invoxis (NLP & KYC, acq.), and Brigad (staffing, series B).

Being passionate about what he experienced and the people he met, he stayed in this fast-paced environment ever since: he later joined Cubyn (fulfillment, series C) and Upflow (@e-founders @YCW20, dunning, series A) before taking the plunge and work on Welii.

Throughout the many adventures he took part in, he shifted away from his tech perspective and progressively grew a solution-oriented approach to better embrace a Product philosophy.

The dude's always running late for his train, so you gotta chug your drink and walk fast to catch up with him :')

Software-as-a-Service (SaaS) has fundamentally changed how companies consume software. But the way businesses buy software is completely broken: they overpay for their SaaS by 30%.

There are several reasons to that: SaaS prices are notoriously opaque, stakeholders buying software lack the time and experience to negotiate, and the limited visibility over the company’s SaaS inventory leads to waste.

That’s why we are building the platform that helps companies pay the fair price for their software, without having to be an expert negotiator and while making the purchase process transparent and collaborative between stakeholders.

Our mission is to help businesses save time and money by taking back control of their software purchases and inventory.

Business software is changing fast & UX/UI is the key source of competitive advantage. SaaS like Notion, Slack, Hubspot or Datadog have transformed the way businesses manage content, communication, marketing or data.

Welii will transform how businesses buy stuff, starting with software.

We’ve already helped scale-ups like Aircall, Jellysmack, Lucca or Skello save millions of € and we are doubling our revenue every 3 months. Our ambition is to become the market leader in Europe and to create a platform that completely changes how companies manage their purchases.
