STARTUP WATCH- Tech investment fund A15 has doubled its initial investment in Dublin-based retail personalization platform Intouch, according to an emailed statement (pdf). The statement does not disclose the size of A15’s investment in the company, which Intouch CEO Sameh Abdallah says will be used to expand its presence in the Middle East. Intouch uses AI to collect data on customers at brick-and-mortar retailers, which it then uses “to optimize customer interactions and operations. The tool helps retailers with physical stores personalize the shopping experience and better connect their customers to appropriate products,” the statement says. Intouch’s technology is used by tier one retailers such as Egyptian convenience store Circle K.
