What's the difference between Weights & Biases ISOs and NSOs?↓
Weights & Biases typically grants a mix of Incentive Stock Options (ISOs) and Non-Qualified Stock Options (NSOs). ISOs: exercised spread is not taxed as income — instead it creates an AMT preference item. Long-term capital gains treatment is available if you hold shares 2 years from grant and 1 year from exercise. NSOs: exercised spread is ordinary income immediately — simpler but less tax-efficient. Both types require payment of the strike price to exercise. Use the PrivatePulse calculator to model the after-tax outcome under ISO vs NSO treatment at the current $2B implied valuation.
