With nearly 40 years of experience, Celeres designs, develops and operates technologies at the heart ofmission-critical activities, with well-established expertise in the space sector, spanning onboard systems for launchers and satellites as well as the ground systems required for European launch campaigns, notably from the Guiana Space Centre in Kourou. Its expertise spans theentire lifecycle of systems and missions – from ground systems and launch infrastructure to command, safety and telemetry solutions – enabling its clientsto rely on a trusted, long-term technology partner.
Drawing on its technological expertise and in-depth understanding of critical environments, Celeres has also successfully begun diversifying into defence, the protection of sensitive sites, and real-time monitoring and control systems for critical infrastructure. It intends to actively pursue this diversification.

A growth strategy supporting European sovereignty

The company intends to build on these strengths to strengthen its position at the heart of major European space programmes and accelerate its diversification into defence and the protection of sensitive sites.
Its development will be driven by continued organic growth and a strategy of targeted acquisitions in Europe, designed to deepen its expertise, broaden its offering and expand its geographical footprint.

This exceptionally strong foundation puts the company in an ideal position tocontinue growing in markets supported by an increasing focus on sovereignty, accelerating investment in space and rising defence budgets. This transactionis fully aligned with Latour Capital’s DNA: supporting the carve-out ofstrategic industrial businesses, preserving their heritage and expertise whilegiving them the autonomy and resources they need to enter the next phase oftheir development. We are delighted to begin this new chapter alongside the Celeres teams, with Boris’ arrival bringing fresh leadership and momentum.”
Ángel Ramírez, co-founder of GTD, said: “This transaction marks an important milestone in GTD’s history, and Latour was thenatural choice. From our very first discussions, its teams understood the distinctive nature of our businesses, the value of our expertise and the importance of preserving the company’s entrepreneurial heritage. Their approachcombines the best of both worlds: substantial financial and strategic resourcesto accelerate Celeres’ development, alongside a strong entrepreneurial and operational culture. By choosing to reinvest and participate in Celeres’ governance alongside Latour Capital, we aim to provide continuity for thecompany and reaffirm our confidence in its teams and its growth potential.”
Boris Symchowicz, Chief Executive Officer of Celeres, added: “Since joining, I have discovered a remarkable company thatdeserves greater visibility.
