Meet Our Founders

Three senior procurement and negotiation professionals with 50+ years of combined experience at world-class enterprises.

It all started in 2016, when Thomas, Remy and Sopheap crossed paths as Global Commodity Leads at a global health technology provider, together responsible for over €1B in annual IT spend.

We found that it was very hard to find real IT Sourcing specialists and negotiators with deep understanding of the IT sourcing world. The market is dominated by large consultancy firms and software resellers, but is lacking truly independent, expert niche IT sourcing know-how specifically to support large deals with vendors like Microsoft and SAP.

So we decided to build it ourselves, and in 2018, Strivesource was born.

The name Strivesource comes from the drive to consistently deliver best-in-class results, combined with our passion for procurement and IT. What brought us together was more than just experience — it was shared values and an entrepreneurial mindset. We work hard, we build real relationships, and we operate as one team. That’s still what sets us apart today: at Strivesource, we believe there’s always a way to strive for success.

Since then, that mindset has translated into lasting relationships and real results. We’re still working with several of our first major clients today, eight years later — a testament to the trust we’ve built as we take on their biggest and most complex challenges, from large-scale IT divestment programs to high-stakes IT vendor deals.

Our track record is proof that independent, expert advice pays off — and we repay that trust with significant cost savings for our clients.
