In his first public appearance since taking the reins of Twitter from co-founder Jack Dorsey, Agrawal says his top priority is “improving our execution” and streamlining how Twitter operates. His comments, made at the Barclays technology conference, come after activist investor Elliott Management shook up Twitter’s board of directors last year and pressured Dorsey to step down from his part-time CEO role. Dorsey remains the CEO of Block (formally called Square).
