The VC Math Reality Check

Why VCs need huge returns

The Problem

17 companies will fail

8 will return some capital

Only 2 will drive fund returns

70.0% failure rate is industry standard

The Math

Each winner must return:

$150M

That's 50.0x on investment

To achieve 3.0x fund return

Your Target

Required exit valuation:

$100B

With 15.0% VC ownership

Based on Series A scenarios

Key Insight: Why VCs Say No

For this fund to succeed, your company needs to reach a $100B valuation. If VCs don't see a clear path to this scale in your market size, business model, or unit economics, they'll pass regardless of current traction. This is why they focus on TAM, scalability, and winner-take-all dynamics.

5-Year Targets to Hit VC Returns

What you must achieve

Reality Check: To make this VC fund work...

Your B2B SaaS needs to reach $10B revenue by Year 5 (exit at $100B = 10x revenue multiple)

Customers Needed

200,000

By Year 5

Growth Rate Required

Year 5$10B200,000180,000$180M100.0%

The Bottom Line:

Your B2B SaaS needs to acquire 40,000 customers per year at $50K ACV, growing 900% annually to hit VC return requirements. Warning: Requires >10% market share - extremely difficult to achieve.

Dilution Journey: Founder to Exit

Dilution Reality Check:

Founders typically own 10-25% at exit after multiple rounds. The key is ensuring the pie grows much larger than the percentage you give up. Would you rather own 100% of a $1M company or 15% of a $500M company?

B2B vs B2C: What It Takes to Hit VC Returns

B2B SaaS Requirements

Customers by Year 5:200,000
Annual Growth Rate:900%
Revenue by Year 5:$10B
Market Share Needed:100.0%

Challenge: Must acquire enterprise customers at scale while maintaining high ACVs

B2C Mobile Requirements

Users by Year 5:100,000,000
Annual Growth Rate:741%
Revenue by Year 5:$10B
Market Share Needed:20.0%

Challenge: Must achieve massive user scale with monetization in huge competitive markets

The Reality Check:

Both models require extraordinary execution to hit VC return requirements. B2B needs enterprise sales excellence and retention mastery. B2C needs viral growth mechanics and monetization at massive scale. Most startups fail because they underestimate what "venture scale" actually means.
