AIMMS: Who We Are (and why it matters)
It all started in 1989, when we saw a huge untapped potential for mathematical optimization. Since then, AIMMS has touched many aspects of people’s daily lives—from the electricity delivered to our homes and the distribution of vaccines to emission-reduction policymaking. Today, as a product-led SaaS company, we support industries worldwide—from logistics to sustainability—enabling smarter, faster, and greener choices.
We’re a diverse, collaborative, and curious team of over 20 nationalities, with offices in the Netherlands (Haarlem HQ), the US, and Singapore. Working in a self-organized, hybrid way across the globe, we’re guided by four core values - Integrity, Care, Open, and Ambition - which help us give honest feedback, care deeply for our stakeholders, collaborate across teams, and continuously grow our impact.
How AIMMS made impact:
Our platform was used to build applications that helps state utilities buy electricity from hundreds of power stations, ensuring companies and consumers always have power. We optimize daily and real-time purchasing decisions to minimize costs, maintain network stability, and reliably meet demand.
