Rooted in the entrepreneurial spirit of our team, we are passionate about partnering to accelerate growth and forging scalable business models. Our patient capital affords us substantial transactional flexibility. We pride ourselves on our ability to make decisions quickly and efficiently. 

OM19 targets businesses with defensible market positions, high operating leverage and significant barriers to entry for private equity transactions.  We typically seek control positions. Our team has a proven record of collaborating with seasoned management teams and aligning incentives to help build shareholder value. We focus on sectors including niche manufacturing, tech-enabled business services and food and ingredients. OM19 is an ideal partner for entrepreneurial business owners and operating teams looking to scale rapidly while also preserving existing culture and legacy.

OM19 seeks hedge fund partnerships with managers who have have repeatable and durable investment processes. We believe that public market competition is fierce and that sustainable advantages manifest through acute focus, so our long-term partnerships are formed with sector and subsector specialists.  

OM19 pursues venture capital partnerships with both founders of revenue-generating businesses and fund models that fit into the same sectors we target for our private equity investments.  We leverage our unique institutional knowledge and professional networks to cultivate business growth.
