We use ground-breaking methods to solve large, complex business optimization problems and provide the fastest, most reliable result.

We’re Hiring

Technology

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.

Team

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.”

Carl Ledbetter

Co-Founder, Chairman & CTO

Prior to co-founding SimpleRose, Carl was Managing Partner at Pelion Venture Partners for 10+ years and has served on the boards of 20+ companies. Previous to his venture capital career, Carl held senior executive positions at IBM, AT&T, Sun Microsystems, ETA Systems/Control Data, and Novell. Carl holds a Ph.D. in Mathematics from Clark University.

Marti Martindale

Co-Founder & COO

Prior to co-founding SimpleRose, Marti founded a management consulting agency. Before that, she led the product management group at ETA Systems, the supercomputing subsidiary of Control Data. Marti holds a M.S. in Mechanical Engineering from Dartmouth College.

Mike Anthony

Director of Engineering

Mike has more than 20 (but less than 30) years of experience in software development and management. He is a highly skilled software architect and developer with extensive experience building cloud-based and SaaS applications, micro services, server applications, and desktop software. He nurtures his passion for games and ComicCon and does not hide his enthusiasm for things Star Wars, Star Trek, and Disney, including D-World and cruises. Oh, and Firefly.

Dr. Scott Johnson

Senior High Performance Computing Engineer

Scott is an entrepreneurial-minded engineer with an interest in high-performance computing, complex systems, and analytics applied in a variety of problem spaces. He previously founded, funded, and successfully exited a company that developed simulation software for the upstream oil and gas industry. He enjoys traveling with his wife and young son and knows more about primates than anybody else in the company.

Zhihao Yuan

Parallel Computing Engineer

Zhihao is an expert C++ and Python developer with a zeal for continuous integration, code review, and unit testing. His participation on the ISO C++ program committees (he is one of about 170 people serving worldwide) makes him uniquely positioned to provide real-world and state-of-the-art development expertise. Really, he’s pretty much freaking Yoda when it comes to C++. We’re not kidding…freaking Yoda.

Mark Ostroot

Parallel Computing Engineer

Mark is our GPU expert who began his career working with vision systems and is now helping us build our CUDA expertise with best practices, tools, and methodologies. In addition to his tenacious commitment to working out and serving as company liaison for the St. Louis cultural scene, he enjoys picking locks. Fortunately, he can run fast in the event lock-picking doesn’t go well.

Palaniappan Chellappan

Optimization Engineer

Palaniappan enjoys mathematical modeling, linear and nonlinear optimization methods, and exploring heuristic solutions. He developed an on-demand transportation system that is a mashup between ride sharing and fixed route buses. Palaniappan prefers his own cooking so much that it is difficult to talk him into going out to eat at a restaurant. He also has a wicked sense of humor.

Constantino Schillebeeckx

Senior Data Engineer

Constantine has more than 10 years’ experience in the design and implementation of complete data frameworks including computation pipelines, modeling and ML prediction, and visualization. His innate curiosity has helped him grow into working more heavily with AWS and he’s a master at picking up new technologies quickly. We’re also pretty sure nobody can spell his last name from memory, let alone pronounce it correctly.

Erika Olsen

Manager of People & Culture

We all know who really makes things work at SimpleRose. It’s Erika. Without her, none of us would get paid. It’s generally a good idea to stay on her good side as a result. Which is exactly why we’ll just say she’s awesome. In addition to completing the LaunchCode’s CoderGirl program, she is becoming a LaTeX guru to support our documentation. She types so fast that we had to put her in her own office to control the noise.

The city is a great place to live, and as congestion and cost of living go up in other top metromarkets, the St. Louis region is becoming a destination location for both employers and employees. And it’s sunny 202 days a year here!
