Build an AI Engineering Decision Logger
The Problem
New engineers spend weeks digging through closed PRs to understand decision rationale, as no tool auto-captures context from commits.[signal description] Engineering leaders use platforms like LinearB and Waydev, with markets showing 41% AI-generated code needing better visibility, but current tools aggregate metrics without decision logs. Teams currently spend $15-50 per developer/month on adjacent devtools, with thousands of software companies adopting these (e.g., top platforms track performance for 100K+ engineers globally).
Core Insight
Unlike LinearB, Waydev, and Typo which focus on metrics and blockers, this tool auto-captures commit-level decision context as a searchable logger, eliminating weeks of PR digging and providing instant 'why' insights missing in current platforms.
- Target Customer
- Engineering managers and new hires at mid-stage SaaS companies (50-500 engineers), in a $5B+ devtools market where AI engineering intelligence platforms grew 3x in 2025.
- Revenue Model
- SaaS tiered at $19-39 per developer/month (undercutting Milestone at $49, matching Waydev/LinearB), with freemium for solo devs and outcome-based upsell for enterprises to capture 20-30% market share in decision logging niche.
Competitive Landscape
$20 per developer/month (Pro plan)
LinearB focuses on PR flow and delivery efficiency metrics but lacks auto-capture of decision context from commits, requiring manual review of PRs to understand engineering choices. It does not provide an 'engineering flight recorder' style logging for why decisions were made.
Starts at $15 per user/month (Team plan)
Waydev offers lightweight visibility into delivery signals and AI conversational insights but misses automatic context capture from commits, forcing new engineers to dig through closed PRs manually. It emphasizes trend visibility over decision rationale logging.
Custom enterprise pricing (outcome-based)
Typo provides AI-driven workflow clarity and delivery blockers from SDLC data but does not auto-log engineering decision context from commits, leaving gaps in understanding historical choices without PR digging. It prioritizes fast insights over comprehensive decision archives.
Starts at $49 per developer/month
Milestone acts as an 'engineering flight recorder' for lifecycle signals but reviewers note it requires setup across tools and lacks seamless commit-level decision auto-capture for quick context on why choices were made. It focuses more on proactive blockers than historical decision logging.
Custom pricing, typically $25+ per engineer/month
Jellyfish excels in initiative alignment and investment visibility but does not capture or log decision rationale from commits automatically, relying on aggregated metrics over granular engineering context.
Willingness to Pay
