Welcome, folks, to Week in Review (WiR), TechCrunch's newsletter that recaps the major happenings in tech over the past few days. In this edition of WiR, we cover Teamshares, a New York–based VC-backed startup quietly buying mom-and-pop shops; Zepto, which became India's first unicorn of 2023; OpenAI, which is launching a ChatGPT for enterprise customers; and Google, which is unveiling BigQuery Studio, a "new way" to work with data. There goes the neighborhood: Teamshares has big ambitions to capitalize on an opportunity in plain sight: that of small businesses without a succession plan.
