Speaker

Eno Reyes, co-founder of Factory, explains how the company’s Droid coding agent supports software development and broader product work in a conversation with Peter Yang on the Peter Yang channel.

Building for enterprise software teams

Reyes says Factory has spent about two and a half years building Droid for organizations that need enterprise controls. Alongside terminal, IDE, web, and desktop interfaces, Factory offers codebase analysis, ROI analytics, and controls for managing agent use.

Turning a conversation into a working prototype

Reyes uses notes from a Granola conversation as input for a speed-reading web app. In Spec Mode, Droid asks what the app should do, creates a specification document, and uses that spec to guide implementation. Reyes says users can change autonomy, models, and modes during a session.

Making agents validate their work

Reyes argues that agents are limited by how well they check their own output. Droid runs builds, linters, and type checks, and uses browser screenshots and interactions to review the app. The demo also shows Droid adapting the app to Factory’s existing colors, components, and fonts by reading the codebase.

Giving agents company context

Reyes describes skills, MCP, hooks, and shared configuration as ways to customize agent workflows. His product management skill draws on Factory’s product principles, positioning, prioritization frameworks, and templates, including documents in Notion. He says this context helps produce PRDs and design documents that reflect the company’s established language and practices.

Extending coding agents across roles

Reyes says Factory mainly hires product engineers, while employees in roles such as sales also use Droid for customer research, usage analysis, and deal tracking. He describes enterprise customers expanding access beyond software engineers so teams like product, operations, QA, and data science can ask questions about codebases. Factory focuses on difficult enterprise code problems, including legacy systems and refactoring.

Takeaways

  • Give an agent a clear specification of what to build, and let it determine the implementation steps.
  • Make validation part of the agent workflow with builds, tests, type checks, and browser review.
  • Ground agent output in existing code, design patterns, and company source documents.
  • Use skills to package repeatable workflows and organizational context for teams.
  • Consider read access to codebases for colleagues involved in software delivery, even when they do not write code.
