Headquartered in San Diego, PlanetTogether is the only advanced planning and scheduling (APS) software company based in the United States. Since 2004, we have helped manufacturers from mid-sized firms to Fortune 500s optimize billions in production output each year with a platform rooted in Cornell University research. Backed by a global network of experts, our mission is simple:

Make the planet more productive, one factory at a time.

We believe manufacturing drives better living, and our passion is helping clients run smart factories at peak productivity with less stress.

PlanetTogether is the result of decades of academic research at Cornell University combined with over 25 years of industry experience applying software technology to solve complex production planning and scheduling challenges.

The company builds on the legacy of Dr. William Maxwell and Dr. Richard Conway, Cornell professors and authors of Theory of Scheduling, considered the “Bible” of production scheduling. Their groundbreaking research transformed how manufacturers approach capacity and efficiency.

Founder Jim Cerra, together with co-founder Larry Hargis, studied and worked under Maxwell and Conway from the early days of C-Way Systems, a pioneering venture in finite capacity scheduling software later acquired by Epicor. Their mission with PlanetTogether is to bring that same blend of science, technology, and passion to manufacturers worldwide.
