MK Capital Announces Sale of OneCause to Bonterra – October 2025
Chicago, IL – October 15, 2025 – MK Capital announced today that its portfolio company, OneCause, a leading provider of digital fundraising and donor engagement software for nonprofits, has been acquired by Bonterra, a mission-driven technology leader serving social good organizations. This exit underscores MK Capital’s focus on scaling mission‑critical, market‑leading software platforms and recognizes the exceptional accomplishments of the OneCause team.
Since first partnering with OneCause in 2011—then known as BidPal—MK Capital has supported the company’s evolution from event-centric fundraising to a comprehensive, year-round giving platform spanning mobile bidding, peer-to-peer, donor engagement, and fundraising intelligence. As part of that partnership, MK Capital helped recruit Steve Johns to serve as Chief Executive Officer. Under his leadership, OneCause accelerated ARR growth, expanded across nonprofit segments, and strengthened ecosystem partnerships – advancing its mission to help nonprofits raise more and do more good.
“From the outset, we believed OneCause could set the standard for modern nonprofit fundraising software,” said Kirk Wolfe, Partner at MK Capital. “Our work together focused on building a durable product foundation, elevating go-to-market execution, and recruiting an outstanding leadership team. Today’s outcome is a credit to the OneCause team’s customer obsession and execution, and it reinforces MK Capital’s commitment to backing industry-leading software companies.”
OneCause will integrate into Bonterra’s platform to deliver expanded functionality, data-driven insights, and a unified donor experience that helps nonprofits activate, engage, and retain supporters more effectively.
“Joining Bonterra amplifies our ability to serve nonprofits with greater capabilities and scale,” said Steve Johns, Chief Executive Officer of OneCause. “MK Capital’s partnership – from strengthening our leadership team to sharpening our go-to-market – was instrumental in helping OneCause expand its impact while staying true to our mission.”
“This acquisition yielded over a 500% return on MK Capital’s investment thanks to Steve Johns’s leadership and an elite executive team, many of whom worked at previous MK Capital companies,” noted Mark Koulogeorge, MK Capital’s Managing Partner. “OneCause’s success validates our long-standing belief that by putting the interests of customers and employees first, investors will ultimately be rewarded.”
