Strategic Investment & Advisory
Building and investing in businesses that are disruptive, scalable, and noble in purpose.
We bring ideas, people, and capital together to create disruptive change that can reposition companies and interrupt industries.
Rainmaker is a strategic advisory and investment firm that works with founders, operators, and leaders building businesses worth building. We bring decades of hands-on experience across industries and continents, and we show up as true partners, not just advisors.
We’ve launched companies, restructured them, scaled them, and sold them. So when we sit across the table from a management team, we already know what they’re up against. What we offer isn’t just capital. It’s alignment, accountability, and a genuine investment in your success.
ABOUT RAINMAKER
OUR PHILOSOPHY
We work with businesses that are disruptive, scalable, and noble in their purpose. That has special meaning to us.
Disruptive
We’re drawn to the builders who see around corners. The innovators and game changers who challenge what’s always been done and open up new ways of engaging the world.
Scalable
A great idea has to be able to grow. We focus on businesses that are positioned to expand beyond their first market, meeting demand locally, regionally, and globally.
Noble
Purpose isn’t a marketing strategy. When a business is built around a mission that genuinely improves lives, it changes how decisions get made, how teams show up, and how lasting the impact becomes.
"I fundamentally believe in the importance of the entrepreneurial spirit and the great things that are possible in business. My work as a strategic advisor informs my role as an investor, and my experience in investing informs my work as an advisor."
— Gregory Campbell, President & CEO, Rainmaker
Disruptive Strategy
We work with leadership teams to rethink how their company competes. That means finding the angles others have missed, building durable advantage, and structuring the business to generate superior margins.
Capital Sourcing
Not all money is good money. We bring our own capital to the table and connect companies with the right investors and partners, people who understand the business and are aligned with where it’s going.
Pathways to
Value Creation
Rapid Scaling
Growth has to be intentional. We help companies scale through a combination of organic momentum and strategic acquisition, clearing the obstacles that slow progress and capitalizing on the opportunities others overlook.
Good Governance
Strong companies are built on strong foundations. We curate and serve on boards that hold leadership accountable, keep strategy clear, and create the conditions for teams to do their best work.

Greg Campbell
President & CEO, Rainmaker · Managing Partner, Prosalus Capital Partners
Greg Campbell has spent five decades building, funding, and advising businesses across the United States, Latin America, and West Africa. His focus has always been the same: businesses that are disruptive in their model, scalable in their reach, and noble in their purpose.
His work has taken many forms. Co-creating Ilumno, a university system that today serves more than 300,000 students across Latin America. Co-founding the North Texas Opportunity Fund, which directed institutional capital toward minority- and women-led businesses. Building HBCUsOnLine.com to help Historically Black Colleges expand into digital education. Developing 285 affordable homes through Solomon Partners in a Dallas community that hadn’t seen new construction in four decades.
Greg currently serves on the boards of Tuleva Inc., Assure.ai, and Curis Functional Health. He teaches entrepreneurship and investing at universities across the country.
What has shaped his perspective most is that companies which have ideas can become a mission, and in turn be built into a scalable discipline and yield substantial value.
He holds a B.S. from Cornell University and an MBA from Harvard Business School.
