Building the future of
AI-powered development

We're a team of engineers from Rippling, Twitter, Visa, Goldman Sachs, and other leading tech companies on a mission to make every developer 10x more productive with AI.

Our goal is to bring world class engineering insight to every developer

We started Propel after seeing firsthand how much engineering momentum is lost to slow reviews, tribal knowledge, and avoidable mistakes. Traditional code review tools lacked true intelligence, and “AI assistants” felt more like autocomplete on steroids than real teammates. Having worked at companies like Rippling, Twitter, Visa, and Goldman Sachs, we saw how engineering teams struggled with inconsistent review quality, knowledge silos, and the constant tension between shipping fast and maintaining quality.

Our goal is to give engineering teams the judgment, speed, and scale of an AI Tech Lead. Code quality, architectural integrity, and development velocity do not have to work against each other. Propel understands your codebase, learns from your team’s patterns, and gives developers contextual feedback they can act on.

The future of software development is not about replacing developers with AI. It is about helping engineers focus on what they do best: solving complex problems, designing better systems, and creating value for users. By handling routine reviews, catching subtle bugs, and sharing educational feedback, Propel helps teams ship better software faster.

The idea for Propel was born from countless hours spent in code reviews that felt more like bureaucracy than collaboration.

As engineers at high-growth companies, we watched talented developers spend entire afternoons reviewing trivial style issues while critical architectural decisions slipped through unnoticed.  We saw junior developers struggle without proper mentorship, senior engineers burn out from repetitive review tasks, and entire teams wait on feedback. The existing tools either provided shallow automated checks or required extensive manual configuration that never quite matched our team’s evolving needs.

What if code reviews could be intelligent, contextual, and educational? What if an AI could understand not just syntax, but the intent behind code changes? What if every developer could get the kind of feedback usually reserved for teams with senior architects and tech leads?

That vision drove us to build Propel as an engineering partner that understands your codebase, learns from your team’s patterns, and gives feedback that helps everyone grow. We’re not just automating code review; we’re making senior-level review available on every pull request.
