Growth through patient investing, industry expertise, and hands-on guidance.

Innovation has always demanded agility and a keen eye for new opportunities, but markets today are more dynamic and competitive than ever before. To succeed in this fast-moving landscape, technology entrepreneurs need the right partners –ones who know how to navigate the uncertain and can offer guidance informed by experience.

We’re different.

At Emerald, we have a unique approach to investing. Because we invest a significant amount of our own capital into your business, we have a stake in seeing you succeed — and we’re there to ensure that you do.

Been there. Done that.

We're operators at the core — not just investors who have never run a company. We've raised billions of dollars as founders and negotiated everything from union labor agreements to tech transfer licenses, and we have the start-up founder experience to steer you through the unexpected.

Emerald’s Success Story

IT STARTED WITH SOFTWARE AND SALT.

Neil Cohen and Charles Collins began their partnership nearly three decades ago as investors backing early-stage companies. The first two of these were an enterprise software company and a salt mine that they founded with additional founders called American Rock Salt (ARS). Through diligent, hands-on management, they built and grew ARS into the largest salt mine in the U.S. ARS has returned over a billion dollars to its investors.

AND GREW INTO EMERALD.

From salt, we moved to finding and polishing gems —investing in and nurturing promising young tech companies. Emerald has since built a portfolio of over 20 companies and has an investment focus on life sciences, enterprise software, cybersecurity, industrial technology, and sustainability.
