More than just an engineering design office, we are a local technology partner. Our organisation combines the agility of a passionate team with the processing power of a state-of-the-art data centre. Our mission? To support manufacturers in the aerospace, rail, shipbuilding and other sectors as they tackle their most complex mechanical challenges.
“Since 2018, Saïna has been transforming mechanical engineering through innovation. Furthermore, our mission is to provide cutting-edge solutions in design and numerical simulation to ensure high-performance, reliable systems.
Forged through demanding projects in the aerospace and rail sectors, our expertise goes beyond conventional engineering. We develop our own digital tools to automate processes and ensure absolute precision, meeting the strictest industry standards.
Indeed, the future lies in continuous optimisation. We invest heavily in digital intelligence and advanced simulation to push the technical boundaries of your projects.
Thank you to our partners for their trust. We remain committed to working alongside you to build, together, the industrial solutions of tomorrow.”
Joris SPANGENBERG
President – Saïna

Based in Latresne, at the heart of the Bordeaux Métropole industrial ecosystem, Saïna supports major players in the Gironde region and across France.
Indeed, our core business combines two pillars of mechanical engineering: precision design and numerical simulation. This dual expertise enables us to work on complex projects where reliability is non-negotiable.
Whether in aerospace, rail, shipbuilding or energy, our engineers apply the cutting-edge requirements of these sectors to your projects, whether in transport or heavy industry.

Evolving High-Performance Computing (HPC) Infrastructure: advanced simulation requires raw computing power. Our current cluster (32 CPU cores / 384 GB RAM) can handle your large-scale meshes. However, the next step is to integrate GPU solutions. This major investment will open the door to AI, enabling us to accelerate our convergence and optimisation phases.
Towards an Integrated Prototyping Workshop: validating the virtual through the real remains essential. Our workshop already has a 3D printer and finishing equipment. Consequently, our ambition is to take things to the next level: acquiring a complete machining system to deliver your functional prototypes in record time.
A Partnership Approach: expanding our portfolio is not just about signing contracts. We seek to build lasting technical partnerships. Manufacturers, partners: let’s join forces to tackle the challenges of tomorrow.
November 2018
The company was incorporated as a single-member simplified joint-stock company (SASU) with a share capital of 1500€. SAÏNA began its work in numerical calculation and simulation, with COMPIN / FAINSA as its sole client and main partner.
July 2021
Having weathered the COVID-19 pandemic, SAÏNA is accelerating its growth: its share capital has been increased to €10,000 and its rail operations are expanding thanks to partnerships with major players such as ALSTOM and BOMBARDIER.
Today
Today, SAÏNA operates across a wide range of sectors, including rail, shipbuilding, aerospace tooling and defence, whilst covering the full spectrum of computational and numerical simulation activities.
... And tomorrow !
With an eye to the future, SAÏNA provides long-term support to its clients and invests in developing its expertise and business tools, as well as in internal advanced innovation projects, particularly those involving drone demonstrators.
