Once ShadowPrice is connected, simply ask Claude about any B2B SaaS vendor:

“What is the real enterprise price for Vercel and how do I negotiate it?”

“We're renewing Datadog for 100 engineers. What should we actually be paying?”

“Compare pricing for Notion, Confluence, and Coda for a 50-person startup.”

“Give me a negotiation playbook for our upcoming Salesforce renewal.”

“What discounts are other Series B companies getting on AWS?”
