The fine print
From Sierra's own site, Aug 5, 2026.No public pricingThere is no pricing page, no tiers and no numbers. Buying Sierra means a demo, a scoping exercise and a negotiated contract, which is normal at enterprise scale and slow if you are a team of five.
Outcome pricing cuts both waysPaying only for resolved conversations aligns incentives, and it also means a successful campaign, a product recall or a seasonal spike lands directly on your invoice. A flat plan with published overage stays predictable.
Built for enterprisesSierra targets large consumer brands with dedicated support and engineering teams. If that is you, take the demo. If not, you would be buying enterprise overhead you do not need.
No self-serve pathThere is no signup that provisions a workspace, so you cannot try it on your own content before committing. Invent gives you a free plan and a working agent in minutes.

Common questions
How much does Sierra cost?
Sierra publishes no prices. It describes outcome-based pricing, where you pay for resolved conversations, negotiated per customer. Invent publishes its pricing: $29/mo with usage included.
What is outcome-based pricing?
You pay when the AI resolves a conversation instead of paying per seat or per message. It aligns cost with value, and it makes your bill rise with your ticket volume, which is exactly when budgets are tightest.
Which is better, Invent or Sierra?
Sierra is built for enterprises running very high volumes with voice and dedicated teams, and it does that well. Invent delivers the same core loop, AI that resolves support with humans in the loop, self-serve and at a price you can read.
Who is Sierra for?
Large consumer brands and enterprises with the volume to justify a negotiated contract and the team to run an enterprise rollout. Smaller teams are outside its target market.
