SimpleRose’s mission is to challenge the limits of optimization.

We enable optimal decision-making in an increasingly complex world where the proliferation of data and growing scope of organizations make it challenging to determine the best outcome.

Our optimization platform is built for the peta/exascale age, leveraging algorithmic innovation on a massively parallel architecture to solve existing problems exponentially faster and tackle larger problems that are infeasible using conventional optimization solutions.

Our applications include scheduling, production planning, and portfolio optimization, solving high-value problems that result in hundreds of millions of dollars of improvement to our customers' bottom line.

Our advantages

Unprecedented Speed and Scaling

Proprietary architecture enables massive parallelism, resulting in thousands of times in speedup.

Differentiated Numerical Accuracy

Automatically prevents a problem from drifting into infeasibility and controls round-off errors.

Dynamic Programming

Continuous analysis updates for real-time variable changes, eliminating onerous and costly reruns and enabling rapid what-if analysis.


With years of experience creating, funding, and managing successful high-tech ventures, our founders came together around their passion for unlocking technical innovation.

"Nothing tends so much to the advancement of knowledge as the application of a new instrument.”
