Charter Growth Capital Fund, a fund managed by the principals of Grand Rapids-based Charter Capital Partners has made an investment into Lambert Global the holding company for PR, investor relations and integrated marketing firm Lambert.

Charter Growth acquired a minority position in the firm with leadership retaining the majority share. Lambert has said proceeds from the debt and equity investment will be used to fund future growth. This includes standing up new practice areas and accelerating its already active M&A activity.

Lambert has posted a compound annual growth rate of more than 20 percent over the past five years. It has recently completed its fifth total-growth transaction within a three-year period, with over 100 team members.

“Lambert has grown from a start-up in my basement to one of the nation’s leading firms for integrated strategic communications,” said Jeff Lambert, founder and chairman of Lambert. “We have aggressively expanded our national clients and service footprint throughout our 23-year history, but never more so than in the last five years, and we believe Charter is a great partner to help us push the pace of growth and M&A.”
