Growth Audit System (GAS)
Ehsan Jahandarpour's six-phase diagnostic methodology — Intake, Infrastructure, Insights, Investment, Inflection, Implementation (the 6Is) — for auditing growth systems and identifying the single highest-leverage intervention. Refined across 50+ audits from pre-seed to Fortune 100.
When to Use
Use GAS before making major growth investments ($50K+), when growth has stalled and the team disagrees on why, when a new growth leader joins, when preparing for a funding round, or when evaluating AI readiness. The audit costs a fraction of a misallocated growth budget.
Origin & Background
Born from frustration with clients who always came with a self-diagnosis ("We need better content" or "We need AI tools") that was wrong more than half the time. Growth consultants would accept the client's diagnosis and build projects around it. The GAS forces a comprehensive six-phase examination with no assumptions, ending with a single prioritized action plan. It is now the core methodology behind the AI Growth Audit service ($5K-$8K engagements).
Framework Steps
Intake
Data collection and stakeholder interviews (1 week): CEO/CMO/VP interviews, analytics access, strategy documents, competitive intelligence, customer feedback data. Document the company's self-diagnosis.
Infrastructure
Tech stack and tool audit (3-5 days): map the complete martech stack using AGSM, evaluate each tool against purpose vs. actual usage, identify overlap and gaps, assess data flow, score maturity per AGSM layer.
Insights
Analytics and data quality audit (3-5 days): audit implementation accuracy, assess data completeness and freshness, test key assumptions, identify data blind spots. Score data quality 1-10 on accuracy, completeness, freshness, accessibility.
Investment
AI spend vs. revenue attribution (3-5 days): map all growth spend, calculate CAC by channel, evaluate AI tool spend using RFAI, identify highest/lowest ROI investments, compare allocation to GAF phase distribution.
Inflection
Identify the #1 growth lever (2-3 days): synthesize all findings, model revenue impact of each issue, rank interventions by impact/feasibility/time-to-impact, validate the Inflection Point with stakeholders.
Implementation
90-day action plan (2-3 days): three 30-day sprints — Sprint 1: quick wins + foundation fixes, Sprint 2: build + optimize, Sprint 3: scale + compound. Assign owners, define success metrics, set re-audit date.
