Former Twitter head of product Kayvon Beykpour announced on Wednesday the launch of Macroscope, an AI system designed to summarize codebase updates and identify software bugs. The new platform, developed for engineers and product leaders, marks the latest venture from the co-founders of livestreaming video startup Periscope, which was acquired by Twitter. Macroscope has secured $30 million in Series A funding, led by Michael Mignano at Lightspeed, contributing to a total of $40 million raised.
Beykpour, now CEO of Macroscope, co-founded the San Francisco-based startup in July 2023 with Joe Bernstein, a childhood friend and former colleague at Periscope and Terriblyclever, which was sold to Blackboard. The founding team also includes Rob Bishop, who previously sold his computer vision and machine learning company, Magic Pony Technology, to Twitter in 2016. The company describes Macroscope as an "AI-powered understanding engine" intended to streamline development workflows.
Macroscope integrates via a GitHub app, with optional connections to platforms such as Slack, Linear, and JIRA. The system analyzes codebases using a process known as code walking, which leverages the Abstract Syntax Tree (AST) to extract contextual information. This data is then processed in conjunction with large language models (LLMs) to provide actionable insights.
The platform enables engineers to discover bugs in pull requests, generate summaries of their changes, and obtain overviews of codebase evolution. Product leaders can utilize Macroscope for real-time summaries of product updates, insights into team productivity, and natural language answers to queries concerning product, code, or development activity. Beykpour stated that such capabilities could offer significant efficiencies for organizations with extensive engineering teams, citing challenges faced at his previous roles.
In the competitive code review landscape, Macroscope positions itself against tools like CodeRabbit, Cursor Bugbot, and Greptile. The company reported an internal benchmark of over 100 real-world bugs, indicating its product caught 5% more bugs than its closest competitor while generating 75% fewer comments. The software is priced at $30 per active developer per month, with a minimum of five seats, and supports enterprise pricing for larger organizations, requiring GitHub Cloud. Early adopters include XMTP, Things, United Masters, and Bilt. The company currently employs 20 individuals.
