Feasibility Assessor
Evaluate business ideas and features across two tracks: financial viability and technical feasibility. Produce an integrated verdict with actionable de-risking recommendations.
Phase 1: Input Classification
Determine the input type:
- Idea pitch: informal description of a concept
- Feature spec: defined requirements for a product addition
- Repo/codebase: existing code to evaluate for extension or pivot
- Business plan: structured document with financials
Extract from the input:
- Value proposition (what problem it solves, for whom)
- Target customer segment
- Pricing intent or revenue model
- Technology stack (stated or implied)
- Competitive landscape awareness
If critical inputs are missing, ask targeted clarifying questions before proceeding. Minimum viable inputs: value proposition and target customer.
Phase 2: Financial Analysis
Reference: references/unit-economics.md, references/financial-viability.md
Skip this phase only when the request is purely technical (e.g., "can we build X with Y stack").
Unit Economics
- Calculate Customer Acquisition Cost (CAC) — fully loaded: marketing spend + sales cost + overhead allocation per acquired customer
- Calculate Customer Lifetime Value (LTV) — ARPU multiplied by average customer lifetime, adjusted for gross margin
- Compute LTV:CAC ratio — minimum viable: 3:1
- Determine contribution margin per unit sold or per customer served
- Calculate payback period — months until cumulative gross profit from a customer exceeds CAC
State every assumption explicitly. Flag assumptions with high sensitivity (small change flips the outcome).
Revenue Modeling
- Identify all revenue streams and size each one
- Assess pricing strategy fit: cost-plus, value-based, competitive, freemium-to-paid
- Apply conversion rate assumptions — use industry benchmarks from reference material
- Model churn and retention — apply cohort decay curves where possible
Break-Even Analysis
- Separate fixed costs (rent, salaries, infrastructure baseline) from variable costs (COGS, transaction fees, support per user)
- Calculate break-even point in units, customers, or revenue
- Model three scenarios:
- Pessimistic: 50th percentile conversion, high churn, slow growth
- Base: industry-average assumptions
- Optimistic: top-quartile performance
Path to Profitability
- Project gross margin trajectory over 12-24 months
- Model operating expense scaling (linear vs step-function vs economies of scale)
- Estimate funding requirements and runway at current burn
- Compare against industry benchmarks for time-to-profitability
Phase 3: Technical Analysis
Reference: references/technical-risk.md
Skip this phase only when the request is purely financial (e.g., "are the unit economics viable for a SaaS at $29/mo").
Architecture Assessment
Classify complexity:
| Level | Description | Examples |
|---|---|---|
| 1 — Simple | Standard CRUD, single service | Landing page, basic CMS, form-based app |
| 2 — Moderate | Multi-service integration, auth, payments | E-commerce, SaaS dashboard, API platform |
| 3 — Complex | Distributed systems, real-time, high availability | Marketplace, streaming platform, fintech |
| 4 — Novel | R&D required, unproven at scale | ML-driven product, novel protocol, hardware+software |
Evaluate:
- Technology stack maturity and ecosystem support
- Infrastructure requirements and cost scaling curve
- Third-party dependency count and criticality
Build Estimation
- Define MVP scope — the minimum feature set that tests the core value proposition
- Estimate development timelines:
- Optimistic: experienced team, known stack, minimal unknowns
- Realistic: standard team, some learning curve, normal blockers
- Pessimistic: new domain, integration challenges, regulatory overhead
- Identify required team skills and availability
- Run build vs buy vs partner analysis for each major component
Risk Scoring
Score each dimension 1-5 (1 = low risk, 5 = critical risk):
| Dimension | What It Measures |
|---|---|
| Technical novelty | Proven tech (1) vs active R&D required (5) |
| Integration complexity | Self-contained (1) vs many external APIs (5) |
| Scale readiness | Architecture handles 100x with config changes (1) vs requires re-architecture (5) |
| Data risk | Public/owned data, no regulation (1) vs restricted data, heavy compliance (5) |
| Security/compliance | No sensitive data (1) vs PCI/HIPAA/SOC2 required (5) |
Composite technical risk = weighted average. Flag any dimension scoring 4+ as a blocker requiring mitigation plan.
Phase 4: Integrated Feasibility Score
Financial Viability
- Viable: LTV:CAC > 3:1, payback < 18 months, clear path to positive unit economics
- Risky: LTV:CAC 1.5-3:1, payback 18-36 months, unit economics depend on scale
- Not viable: LTV:CAC < 1.5:1, payback > 36 months, negative contribution margin
Technical Feasibility
- Straightforward: complexity level 1-2, all risk dimensions < 3
- Challenging: complexity level 2-3, one or two dimensions at 3-4
- High-risk: complexity level 3-4, multiple dimensions at 4+
- Research-grade: complexity level 4, any dimension at 5
Overall Verdict
| Financial | Technical | Verdict |
|---|---|---|
| Viable | Straightforward | Green — proceed |
| Viable | Challenging | Yellow — proceed with caution, mitigate tech risks |
| Risky | Straightforward | Yellow — validate financial assumptions first |
| Risky | Challenging | Yellow — high uncertainty, run cheap experiments |
| Not viable | Any | Red — reconsider fundamentals |
| Any | High-risk/Research | Red — reduce technical unknowns before committing |
Assumption Sensitivity
Identify the top 3-5 assumptions that most influence the verdict. For each, state:
- Current assumed value
- Threshold value that would flip the assessment
- How to validate cheaply
De-risking Recommendations
Rank experiments by cost-to-run vs information-value. Prioritize experiments that validate the riskiest assumptions at the lowest cost.
Phase 5: Report Generation
Structure the output as:
Executive Summary
- One-paragraph verdict with go/no-go signal
- Top 3 risks and top 3 strengths
Financial Dashboard (if applicable)
- Unit economics table: CAC, LTV, LTV:CAC, contribution margin, payback period
- Revenue projection under 3 scenarios (table or description)
- Break-even point and timeline
Technical Scorecard (if applicable)
- Complexity classification
- Risk dimension scores (table)
- MVP scope and timeline estimate
- Critical dependencies and mitigation
Sensitivity Analysis
- Which assumptions, if wrong, flip the verdict
- Threshold values for each critical assumption
Recommended Next Steps
- Ordered list of actions, cheapest validation first
- Clear owners or skill requirements for each step
- Decision gates: what evidence triggers proceed vs pivot vs stop
