One-Liner
A data-driven career decision tool for senior software engineers (5-15 years experience) that backtests career moves against historical outcome data — retention, promotion rates, RSU vesting, post-layoff placement — to recommend the safer path under AI-driven job-market pressure.
AI Thinking Process
World-context bullet 3: HN Ask HN 2026-07-19-25 top thread: 'Should I do CS masters at Cambridge or start as new grad at Amazon?' Career-decision anxiety under AI job-market pressure is dominant HN theme.
Pain grounding: mid/senior software engineer (5-15 YoE, $150K-$450K TC) thinks about 'which move survives AI?' via Blind + HN + informal DMs + occasional exec coach ($500-2K/session). Every 3-9 months: 10-30 hours of anxious thinking.
Verb Transplant: 'backtest' from finance → career decisions. Tool: input career history + specific decision → backtest against 10,000 similar past decisions using anonymized outcome data (LinkedIn scrapes + layoffs.fyi + Blind sentiment + open salary data).
Named incumbents: Levels.fyi (compensation data + trajectory tool added 2025), Blind (peer discussion), Pathrise (coaching, mostly juniors), Reforge, Cal Newport-style coaches, individual senior-eng career coaches ($200-1K/session). Levels.fyi trajectory tool needs Pass 2 verification — likely competitive.
structural adoption barrier strong: senior engineers view career-decision confusion as solo/private tied to professional identity. 'I figure things out myself' trope is structural. Data-driven career tool for senior engineers has the highest adoption barrier in the tool-shaped-product universe for this demographic. Hiring exec coach is a status marker, not just a service.
G207 ceiling: US software engineers senior tier ~800K-1M. 5% adoption × $15/mo × 12 = $9M ceiling — below G207 gate.
Pivot: employer-paid retention-risk tool — identify when senior engineer is 60+ days from resigning based on engagement signals. Different buyer (HR/engineering-leadership), different privacy posture. But Lattice, Culture Amp, Peakon, Gem already have this direction. G002 fires on pivoted framing.
KILLED. Kill reasons: structural adoption barrier (senior engineer identity resists data-driven career tools) + G207 ceiling ~$9M below gate + Levels.fyi trajectory tool occupies data-driven career comparison. HN Ask HN dominant pain is diagnostic not tool-shaped. Kill is FUNDAMENTAL.
Kill Reason
structural adoption barrier: senior engineers view career-decision confusion as a solo, private problem tied to their professional identity — they identify as people who ‘figure things out themselves’ and resist data-driven career tools more than any other demographic. Market ceiling ~$9M at aspirational adoption rates (800K senior-tier US engineers × 5% × $15/mo × 12). Levels.fyi’s trajectory tool (added 2025) likely occupies the data-driven career-comparison angle already.
