The Cap Table — A Founder's Guide to Early Equity Design

#What Is a Cap Table

A cap table is a single view of every equity holder in the company — founders, employees, investors — and the form their holdings take (common stock, preferred stock, options, SAFEs, and so on). It's not just a record of who owns what percentage; it's closer to the company's constitution, determining how much each party gets diluted in future rounds and how voting rights and liquidation preferences actually play out.

#Co-Founder Equity Splits — Why You Should Avoid 50/50

With two co-founders, a 50/50 split looks like the fairest option, but in practice it's the riskiest structure. There's no built-in mechanism for breaking a decision-making deadlock, and later-stage investors frequently hold off on investing because they're worried about ambiguous leadership.

When deciding the split, anchoring on 'who sees this through to the end' rather than 'who worked harder' leads to fewer regrets. Whoever takes the larger stake should also carry a commensurate share of decision-making authority and responsibility.

#The Option Pool (ESOP) — Setting It Up Before or After Seed

The option pool reserves stock options in advance for future grants to employees. It's typically set at 10-15% of total company equity, and exactly when you carve it out completely changes who bears the dilution.

The option pool isn't granted all at once — shares are allocated gradually as new hires come in. Any unallocated portion can be topped up or reclaimed at the next round.

#Round-by-Round Dilution Simulation

Below is a simplified example with two co-founders, a seed round, and a Series A round. Real deals involve more variables — SAFE conversions, option pool top-ups, and so on — that make the math more complex.

#Vesting and the Cliff — What Happens to a Departing Founder's Equity

What should happen to a co-founder's equity if they leave after just six months? Without a vesting clause, a founder keeps their full stake even after quitting. Vesting and the cliff exist specifically to prevent this scenario.

• Vesting — equity is earned gradually only as long as the founder stays with the company (typically over 4 years)
• Cliff — if the founder leaves before an initial period (typically 1 year), their vested equity is treated as zero
• Acceleration — an optional clause under which remaining unvested equity vests immediately upon a sale or acquisition of the company

The standard structure is 4-year vesting with a 1-year cliff: 0% if you leave within the first year, 25% vested at the one-year mark, then 1/48 vesting each month after that. Applying this among co-founders from day one — rather than adding it later — minimizes disputes.

#Five Common Mistakes in an Early Cap Table

1. Splitting 50/50 between co-founders with no vesting clause — if one leaves, there's no way to reclaim their equity
2. Handing out 5-10% stakes to outside advisors early on with nothing attached — nearly impossible to claw back at a later round
3. Setting an oversized (20%+) pre-money option pool right before seed — this sharply cuts into founder ownership
4. Issuing multiple SAFEs over time without ever simulating the conversion — leads to unexpectedly large dilution at Series A
5. Not keeping the shareholder registry, articles of incorporation, and board resolutions in order — this stalls deals during due diligence

#Managing the Cap Table — Standard Tools and Operating Principles

A spreadsheet is enough in the earliest days. Once SAFEs, options, and multiple rounds start piling up post-Series A, moving to dedicated software becomes worth the effort.

• Pre-Seed to Seed — a Google Sheets or Excel template, with separate tabs for as-issued and fully diluted views
• Seed to Series A — adopt dedicated software such as Carta or Pulley, which automates option grants and vesting tracking
• Change history — every new share issuance, option grant, or SAFE should be reflected immediately in board resolutions and the shareholder registry
• Co-founders, the CFO, and legal counsel should all be working from the same up-to-date version

#Self-Check: A Founder's Checklist

1. Is the equity split between co-founders — along with vesting terms — spelled out in your articles of incorporation or founders' agreement?
2. Is your option pool sized appropriately for your hiring plan over the next 12-18 months — neither oversized nor undersized?
3. Have you simulated how the cap and discount terms on your outstanding SAFEs or notes will play out under a Series A scenario?
4. Can you map out a scenario where your ownership stays above 30% five years from now?
5. Are your shareholder registry, board resolutions, and shareholders' agreement all kept up to date?
6. Does any equity granted to outside advisors include vesting or clawback conditions?
7. Is there a written clause covering equity reclamation and redistribution if a co-founder departs?
