Shares of Braze surged in Tuesday’s trade on October 20, rallying 52% to a 22-month high of $45.59 apiece on the Nasdaq after Salesforce (CRM) agreed to acquire the customer-engagement software company, handing existing investors a major windfall. For Braze, the strategic attraction extends beyond the purchase price. Joining Salesforce Inc. could give the technology much broader distribution and greater resources for product development.
