Scenario mode

Uses the assumptions currently visible in the form.

Funding rounds

Add rounds to compound dilution instead of using the flat assumption.

Tax and exercise note

Tax is modeled as a simple 35% effective rate on exit gain. Real treatment can differ by country, grant type, timing, holding period, and employer paperwork.

US ISO early exercise note

Low strike ISO grants sometimes raise an 83(b) election question if early exercise is available. The IRS Form 15620 page explains the filing mechanics; this is a prompt to ask a tax professional, not advice.

At this acqui-hire outcome, your 0.300% diluted stake nets $11,375 after tax and exercise cost, or $1 per option.

The company sells mostly for the team. Your grant may have value, but preference stacks and low proceeds can make the net outcome modest.

At this acquisition outcome, your 0.300% diluted stake nets $255,125 after tax and exercise cost, or $26 per option.

A meaningful sale creates room for common shareholders, but dilution, strike cost, and tax still remove a large part of the headline value.

At this modest ipo outcome, your 0.300% diluted stake nets $1,551,875 after tax and exercise cost, or $155 per option.

A strong but not legendary IPO can turn options into material wealth if your ownership survives dilution and the strike price is low enough.

This is the optimistic path where the company compounds into a major public business. Treat it as upside, not the expected case.

These are illustrative estimates only. Real outcomes depend on cap table terms, dilution, preference structure, taxes, and factors not modeled here. Not financial, tax, legal, or investment advice.

Sensitivity analysis

What changes this outcome most?

Exit valuation

very high

The modeled net value changes substantially across exit scenarios.

If the company exits below investor expectations, common shares may receive much less than the IPO case suggests.

Future dilution

high

Cumulative dilution is modeled at 25.0%, reducing your ownership before exit.

More financing can grow the company while still reducing your slice of it.

Preference stack

high

In smaller exits, preferred shareholders may absorb proceeds before common shareholders receive value.

A company can be acquired and still leave employee common shares with little value.

Tax rate

medium

The effective tax assumption is 35%, which directly reduces taxable gain.

Questions

Questions to ask before you sign

importantcompany

Can I see the latest 409A valuation, fully diluted share count, and option plan terms?

These documents help verify the core assumptions behind the offer.

infonegotiation

How does the cash compensation compare with market salary?

Equity should be evaluated together with salary, not in isolation.

Negotiation prompts

What would make this offer better?

Understand the preference stack

high

Investor preferences can reduce common shareholder proceeds in smaller exits.

Ask for the total liquidation preference outstanding and whether any preferences are participating.
