ZRG Partners acquires Brimstone Consulting Group


ZRG Partners, LLC. (“ZRG” or the “Company”) is a leading global executive search and human capital management firm. It provides a range of executive search, consulting & advisory, and interim solutions across the Industrials, Life Sciences, Consumer, Financial Services, Sports, and Technology industries, among others.


In 2018 following ZRG’s financial partnership with RFE Investment Partners (“RFE”) the organization grew exponentially through increased senior-level hiring efforts. To build on this momentum, in late 2019 ZRG identified an avenue to further diversify and grow its services portfolio of human capital consulting. Through a targeted M&A effort centered around enhancing capabilities, ZRG sought to further differentiate its offering in the marketplace by providing additional consulting solutions for their clients.


G2 Capital Advisors, LLC (“G2”) served as the exclusive buy-side advisor to ZRG leading a strategic M&A effort focused on identifying and engaging with potential acquisition candidates in the human capital consulting market. ZRG and RFE partnered with G2 to leverage the firms’ deep-rooted expertise across the Technology & Business Services practice, with a heavy focus on services-oriented businesses including specialty consulting and executive search.


G2’s mandate with ZRG led to the acquisition of Brimstone Consulting Group, LLC. (“Brimstone”), a leading management consultancy offering solutions across leadership development; diversity, equity, and inclusion; post-merger integration; and more. Headquartered in Camden, Maine, Brimstone serves a range of medium sized to Fortune-500 businesses across the globe. Together, ZRG and Brimstone will leverage an extensive network of Human Capital search professionals, interim financial professionals, and business consultants to better serve its client base.

“The complementary nature of our businesses made Brimstone an obvious partner for ZRG, as we continue to expand our portfolio of talent advisory solutions,” says Larry Hartmann, CEO of ZRG. “Further ensuring a new CEO is successful with the proven process of Brimstone will create a new paradigm for CEO transitions. We are pleased that we can now address two critical areas of leadership to align success for our clients with both strategy work and culture work. We believe when a company aligns strategy and culture with the right talent, amazing success can be achieved, and our offerings now address these three core areas.” 

Andrew Keleher, Vice President at G2 Capital Advisors, commented “The team at G2 has deep roots in the human capital management segment of the market. Supporting one of the world’s fastest-growing executive search/talent recruitment firms on their growth strategy has been a real pleasure these past few years and we look forward to continuing our work together. The recent acquisition of Brimstone Consulting further enhances ZRG’s offering by adding senior level talent that manages a disciplined approach to supporting leaders through business transformation. We are thrilled for both organizations and look forward to seeing their success together in the coming years!”.
