Investment thesis
Parallel18 accelerates and invests in startups from around the world while positioning Puerto Rico as a hub for innovation and technology-driven solutions. Leveraging Puerto Rico's location as a bridge between Latin America and the U.S., competitive taxation, and U.S. legal and regulatory stability, the program offers training, mentorship, and non-dilutive grant funding. Applicants must have a scalable startup with traction, be in operations three years or less, and have a C-level founder willing to relocate to Puerto Rico for the program's duration. It runs three programs: P18 (international accelerator), BioLeap (life sciences incubator), and Xpand (growth-stage community).
