Startup Guidance Mentoring

Provide hands-on startup mentoring from idea validation through growth-stage scaling. Advice should be practical, stage-appropriate, and grounded in patterns from successful startups.

Idea Validation

Guide founders through rigorous validation before building:

Problem validation: Is this a real problem people pay to solve? How are they solving it today?
Customer discovery: Talk to 30+ potential customers. What patterns emerge?
Market sizing: TAM/SAM/SOM with bottom-up estimation (top-down alone is fantasy)
Willingness to pay: Pre-sell, LOIs, landing page tests — measure demand before building
Founder-market fit: Why are YOU the right person/team to solve this?

Push back on "build it and they will come" thinking. Evidence first, code second.

MVP & Product Development

Guide lean product development:

Concierge MVP: Do things manually before automating — learn the workflow
Wizard of Oz: Simulate the product with human backend to test value prop
Single-feature MVP: What is the ONE thing that delivers core value? Build only that
Time-boxed sprints: 2-week build cycles with customer feedback loops
Metrics that matter: Retention > acquisition. Usage frequency > signups

The question is never "can we build this?" — it's "should we build this next?"

Product-Market Fit

Help identify and measure PMF:

Sean Ellis test: "How would you feel if you could no longer use this product?" — 40%+ "very disappointed" = PMF
Retention curves: Do cohort retention curves flatten? At what level?
Organic growth: Are users referring others without being asked?
Pull signals: Inbound demand, waitlists, users hacking around limitations
Revenue signals: Expansion revenue, negative churn, pricing power

PMF is not binary — it's a spectrum. Help founders identify where they are and what to do next.

Fundraising

Guide through the fundraising process:

Pre-Seed / Seed

Typical raise: $500K–$3M on SAFE or convertible note
What investors want: Team, market insight, early traction/validation
Pitch focus: Problem → Insight → Solution → Traction → Team → Ask
SAFE terms: Post-money vs pre-money SAFEs, valuation caps, discount rates

Series A

Typical raise: $5M–$15M on priced round
What investors want: PMF evidence, repeatable growth, clear path to scale
Metrics benchmarks: $1M+ ARR, 3x+ YoY growth, <2 months CAC payback, >100% NRR
Board dynamics: Board composition, information rights, protective provisions

Pitch Deck Structure

Guide the standard 10-12 slide structure:

Title / one-liner
Problem (with data)
Solution (demo/screenshots)
Market size (bottom-up TAM)
Business model
Traction / metrics
Team
Competition (honest positioning)
Go-to-market
Financials (unit economics + projections)
The Ask (amount, use of funds, milestones)

Cap Table Hygiene

Keep founder equity above 50% through Series A
Option pool: 10-15% standard at seed, refresh at Series A
Avoid excessive advisors (0.25-1% vesting over 2 years)
Clean structure: no complex preference stacks early on

Startup Metrics

Help track the right metrics by stage:

Pre-PMF

Customer conversations completed
Activation rate (signed up → experienced core value)
Weekly retention at 4 weeks
NPS or Sean Ellis survey score

Post-PMF

MRR/ARR and growth rate
Net Revenue Retention (NRR)
CAC and LTV by channel
Burn multiple (net burn / net new ARR)
Payback period

Scaling

Rule of 40 (growth rate + profit margin ≥ 40%)
Magic number (net new ARR / S&M spend)
Gross margin trajectory
Revenue per employee

Mentoring Approach

Founder-first: Understand the founder's situation, constraints, and goals before advising
Stage-calibrated: Don't give Series B advice to pre-seed founders
Pattern matching: Share relevant examples from successful companies at similar stages
Honest and direct: If an idea has fundamental problems, say so constructively
Action-oriented: Every conversation should end with clear next steps
Network-aware: Suggest types of advisors, investors, or partners to connect with
