How pricing works
These two tools don't price the same way, so the headline numbers below aren't directly comparable until you plug in your own volume.
- Help Scout (Per Seat) — Help Scout bills on a fixed plan from $25/mo, so the listed price is what you pay regardless of volume.
- Sierra (Per Usage) — Sierra bills purely on usage. There is no fixed per-seat fee, so the monthly cost depends entirely on how much you consume.
Per-minute, per-credit and per-token rates exclude any downstream model, speech or telephony costs unless the vendor states otherwise.
Customer support platform positioned as the alternative to Zendesk for teams that want email-first support (not ticket-first). Distinctive for its shared inbox UX — customer conversations look like Gmail threads, not tickets. Priced $22-$65/user/mo. Bootstrapped by Nick Francis (still founder-led after 15 years). Popular with SMBs and mid-market SaaS whose support volume is manageable in an inbox format.
AI-native customer experience platform founded by Bret Taylor (ex-Salesforce COO) and Clay Bavor (ex-Google). Positioned to compete with Ada + Decagon at the strategic enterprise level. All pricing custom-quoted, reported deals $200K-1M+/year. Customers include WeightWatchers, SonderMind, SoFi.

What each is best for
Help Scout is worth it if… small support teams (3-30 agents) that want customer-facing simplicity — emails don't look like tickets — with strong knowledge base and light AI. Standard covers small teams; Plus adds custom fields and reporting; Pro adds concurrent chats and advanced features.
Sierra is worth it if… Sierra is only worth engaging with if you're a mid-market or enterprise support org running a serious evaluation of autonomous AI agents — the co-founders' pedigree (Bret Taylor ex-Salesforce COO) opens doors that other startups can't. Deal size $200K-1M+/year.
