Endeavor Puerto Rico's Ecosystem Scan #004, a 75-page analysis published in August 2025^[1], is the most detailed portrait yet of the startup economy taking shape on the island: 520 active Puerto Rico-based companies analyzed^[2], 69 of them surveyed as high-potential^[3] - and, underneath both counts, more than 500 active startups operating in Puerto Rico today^[4]. The base is young: 39% of active startups were founded since 2020^[5], the peak year alone launching 50 new companies^[6], a generation that came of age through Hurricane María, the pandemic and a stretch of fiscal and domestic shocks^[7]. The money is real, but it is not the engine. Startups raised $520 million in private equity and venture capital in 2022 alone^[8], part of more than 120 funding rounds between 2020 and 2024^[9] - yet when founders name what actually drives their growth, financing lands at just 7%^[10], behind innovation (23%)^[11] and strategic alliances (23%)^[12]. The appetite is there: 45% of entrepreneurs call access to capital a major or critical challenge^[13], and 36% have never secured external financing at all^[14]. They want the money. They have learned not to wait on it. The revenue lines show what that discipline produces. Median startup revenue rose from $75,001 in 2022^[15] to $500,001 in 2024^[16], with the average reaching $1.45 million^[17]. Two of the ecosystem's standouts - Abarca Health and nBeta - earned Outlier recognition from Endeavor Global for exceptional growth while remaining fully bootstrapped^[18]; Abarca founder and CEO Jason Borschow built the company without outside capital^[19]. The ecosystem's connective tissue is human, not financial. Eighty-two percent of founders have benefited from mentorship^[20], and accelerators and incubators support 46% of the startups that receive outside help^[21], ahead of government programs at 19%^[22]. Mentorship is locally grounded - 68% of mentored founders were born in Puerto Rico^[23] - while funding is more globally sourced, with 60% of funded founders island-born^[24]. The culture underneath may be the rarest asset of the three. In 2023, 68% of Puerto Ricans knew someone who had started a business in the past year - a 20.5% rise over pre-pandemic levels and among the world's highest^[25] - and 37.1% planned to start one within three years, nearly twice the U.S. mainland rate^[26]. A third of ventures already target customers outside the island^[27], and the economy they sit in added roughly 183,202 jobs since 2015, an 18.6% increase^[28]. What is missing is not ambition or traction. Six in ten founders call hiring technical talent a moderate, major or severe obstacle^[29]. The scan's picture of Puerto Rico is an ecosystem whose operating model was forged by scarce capital - innovation-first, alliance-driven, mentor-powered - now deciding what it becomes as the money finally shows up.
