    Summary

    Summary

    Superhuman, an AI-native productivity platform, faced challenges in increasing developer output without expanding its engineering team. By making AI the default way of work, the company achieved a 60% increase in developer output, shipped over 1,300 autonomous pull requests in a single half, and tripled experimentation rates.

    Background

    Superhuman, formerly known as Grammarly, operates in the AI productivity industry and has an annual revenue exceeding $700 million. The company serves over 40 million users and 50,000 organizations worldwide. Before deploying AI, Superhuman's platform team struggled with flat headcount and a growing backlog of maintenance work, limiting their ability to increase output.

    Challenge

    The primary challenge was to enhance developer productivity without increasing headcount. The platform team needed a solution to boost output amidst constraints of hiring skilled talent and managing a growing backlog of tasks.

    Solution

    Superhuman implemented AI as the default mode of operation for its platform team. This included a weekly “AI Friday” ritual for sharing experiences, workshops, and hackathons to encourage AI adoption. They also created a self-service prototyping platform and connectors for AI tools to access internal systems without approval queues. The result was a significant increase in the number of engineers actively using AI tools, from 51% to 89% within a year.

    Results

    The deployment of AI led to a 60% increase in developer output, with engineers merging an average of 4.15 pull requests per week, up from 2.5. The platform team shipped over 1,300 autonomous pull requests across 90+ repositories in a single half. Additionally, engineers reported saving approximately 6.5 hours per week due to increased efficiency.

    Key Insights

    • Prioritize platform-first strategies to enable widespread improvements across teams.
    • Recognize that AI economics differ from traditional ROI; measure time saved and backlog reduction separately.
    • Prepare the environment and practices before scaling AI usage to ensure smooth adoption and integration.
    • Measure various performance metrics beyond perceived speed to capture the true impact of AI on productivity.
