Choosing between MarshBerry and Optis Partners

MarshBerry and Optis Partners both work in Insurance. Founders running a sell-side process in those categories often see both names on their advisor longlist, which is why this comparison comes up. Both firms position themselves as industry specialist advisors, so the choice is less about category and more about pattern recognition, senior attention, and process fit.

MarshBerry is headquartered in Cleveland, OH and was founded in 1981, while Optis Partners operates out of Chicago, IL and was founded in 2002. Geography matters here: MarshBerry's Cleveland relationships and Optis Partners's Chicago relationships will overlap on national strategics but diverge on the regional private equity buyer set most likely to push price. On deal-size focus, MarshBerry states $5M-$200M while Optis Partners states $5M-$100M.

For founders deciding between MarshBerry and Optis Partners, the honest recommendation is to take a working session with each named partner before signing. Read the firm-level reviews on BankerNotes for the pattern that matters most: did the partner who pitched the mandate run the buyer calls and final negotiations, or did the work slide down the org chart by week six. That pattern, more than league-table position, is what separates a good outcome from a mediocre one.
