Alessandro Marianantoni

CEO MEDIARS, LLC

Alessandro Marianantoni is the Executive Director and Founder of M Accelerator in Los Angeles, a hub for innovation and entrepreneurship. With a focus on building scalable, sustainable business ecosystems, Alessandro and his team provide programs that serve the Los Angeles and international startup ecosystems, equipping students, early-stage founders, and later-stage entrepreneurs with the tools they need to grow their ventures.

At M Accelerator, we collaborate with private equity firms, government organizations, universities, and corporations to create custom innovation programs. These programs are tailored to accelerate growth, unlock product-market fit (PMF), establish go-to-market (GTM) strategies, and drive long-term success for founders and businesses alike.

In a few words, we are more than an accelerator. We build innovation ecosystems designed to foster business development and sustainable growth. For select teams, we take a hands-on approach, working closely with founders to achieve key milestones and deliver high-impact results.
