Los Angeles accelerators Amplify.LA and MuckerLab, as well as Techstars of Boulder, Colo., which runs a local healthcare accelerator on behalf of Cedars-Sinai Medical Center, have been ranked as top accelerators by an academic study.

The Seed Accelerator Rankings Project gave all three accelerators a “platinum tier” status, which is the top ranking for U.S. based programs. Rice University, Massachusetts Institute of Technology and University of Richmond produced the study to help entrepreneurs better identify worthwhile accelerator programs.

“There are new accelerator programs popping up every month,” Yael Hochberg, an entrepreneurship professor at Rice’s Jones Graduate School of Business, who helped with the study, said in a statement. “Our goal is to generate a larger conversation about what makes some seed accelerators more successful and help entrepreneurs find the right fit for their startup.”

The accelerators were ranked based on the valuation, exits, survival rates and additional financing rounds that portfolio companies received after participating. Nearly 1000 individual accelerator participants were also surveyed on their satisfaction.
