Choosing between Greenwich Group International and Halpern Capital

Greenwich Group International and Halpern Capital both work in Cross-Border, Lower Mid-Market. 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 boutique advisors, so the choice is less about category and more about pattern recognition, senior attention, and process fit.

Greenwich Group International is headquartered in Greenwich, CT and was founded in 1989, while Halpern Capital operates out of Miami, FL and was founded in 2010. Geography matters here: Greenwich Group International's Greenwich relationships and Halpern Capital's Miami relationships will overlap on national strategics but diverge on the regional private equity buyer set most likely to push price. On deal-size focus, Greenwich Group International states $10M-$100M while Halpern Capital states $5M-$75M.

For founders deciding between Greenwich Group International and Halpern Capital, 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.
