Weave
WorkWeave
Weave is an ML-powered tool to measure engineering output, that actually understands engineering output! Almost every eng leader already measures output - either openly or behind closed doors. But they rely on metrics like lines of code (correlation with effort: ~0.3), number of PRs, or story points (slightly better at ~0.35). These metrics are, frankly, terrible proxies for productivity. We’ve developed a custom model that directly analyzes code and its impact, with a far better 0.94 correlation. We've created a standardized engineering output metric that doesn’t reward vanity. Even better, you can benchmark your team’s output against peers while keeping everything private.Starting Price: $0 -
