Former Twitter product head Kayvon Beykpour and his team, who previously sold Periscope to Twitter, launched Macroscope, an AI-powered code understanding engine for developers and product leaders. The tool summarizes codebase updates, detects bugs, and integrates with GitHub, Slack, and JIRA. Priced at $30 per developer monthly, it targets engineering efficiency and has raised $40 million, including a $30 million Series A led by Lightspeed.
