Help me price {{PRODUCT}}.

Customers: {{SEGMENTS}}. Costs per customer: {{COSTS}}. Competitor prices: {{COMPETITORS}}. Current price, if any: {{PRICE}}.

1. Recommend a pricing model (per seat, usage, flat, one-time) and why.
2. Design 2-3 tiers: name, price, who it is for, what is included, and the one feature that makes people upgrade.
3. Explain the value metric each price is tied to.
4. Annual discount and free trial / free plan recommendation.
5. 3 experiments to validate the price with real customers.

Show the margin per tier using my costs.
