Why people move off Sierra AI
- No self-serve option; fully enterprise sales, which means months to get live
- Pricing is opaque; outcome-based sounds appealing until you model it at scale
- $10B valuation creates pressure to maintain pricing discipline, discounts may be limited
- Genuinely new company (2023); fewer years of production data compared to Intercom or Ada
Worth weighing against what it does well: founded by credible operators with real enterprise software experience, not just AI hype
