Startup Equity Splits: Fair Allocation Guide for Founders

Equity splits are one of the most contentious and critical decisions founders make. As discussed on The Tech Brothers Podcast Network, getting this wrong can destroy co-founder relationships and derail promising startups. Here's how to approach equity allocation strategically.

The Fundamental Principle: Equal Isn't Always Fair

Many founders default to equal splits (50/50 or 33/33/33), but this often leads to problems. The key question is: who is contributing what, and for how long? Consider factors like initial idea contribution, domain expertise, capital investment, full-time commitment, and role criticality.

The Dynamic Equity Model

One framework gaining traction is dynamic equity allocation, where equity is earned over time based on actual contributions. This rewards sustained effort rather than just being present at founding. Use vesting schedules (typically 4 years with 1-year cliff) to protect against early departures.

Common Equity Allocation Mistakes

• Splitting too early: Decide equity splits after roles and commitments are clear, not on day one
• Ignoring opportunity cost: Someone leaving a $200K job deserves different consideration than someone leaving a $60K role
• Not documenting agreements: Always formalize equity agreements with proper legal documentation
• Forgetting about dilution: Factor in future fundraising rounds and employee option pools

Employee Equity Considerations

For early employees, typical equity ranges are: first engineer (0.5-2%), first salesperson (0.5-1.5%), and senior executives (0.25-1%). These should vest over 4 years. Remember that equity is part of total compensation—balance cash salary with equity grants based on your runway and the candidate's risk tolerance.

At TBPN, we've seen countless equity disputes resolved by having difficult conversations early. Founders who document their reasoning and revisit allocations as roles evolve tend to maintain healthier relationships. And while you're navigating these challenging conversations, a comfortable Tech Brothers hoodie can make those long strategy sessions more bearable.

The TBPN Equity Framework

Our community recommends: start with a spreadsheet listing all contributions (capital, IP, sweat equity, opportunity cost), assign point values, calculate percentages, then negotiate and document. Build in mechanisms to adjust if circumstances change dramatically in the first 6-12 months.
