What Sierra offers

Evaluate Sierra against your requirements, including support for your team after launch.

Sierra publishes customer results and supports several channels, including voice. Its tools include simulations and debugging. Ask for a reference with your systems and ticket mix. ^[3]^[1]^[1]

Sierra charges for agreed outcomes. Escalated or unresolved conversations usually carry no charge under that model. Confirm the exact contract terms. ^[2]

Sierra also describes blended billing for some interactions. Ask which workflows use outcome pricing and which are billed per conversation. ^[2]

What to clarify with Sierra

These questions affect setup, ongoing control and cost.

Get the rate and minimum commitment

Sierra, Decagon and Ada require quotes. Reported contract ranges are not published rates and should not set your budget. ^[2]^[5]^[8]^[9]

Lorikeet and Fin publish rates you can model before a sales call. A published rate is not necessarily a lower total cost. ^[6]^[7]

Include the human helpdesk

Sierra connects to existing systems and transfers to human agents with summaries. Confirm the inbox and integrations your team will use. ^[1]^[5]^[8]

Test a handoff. Check customer history, actions already taken and reporting across the AI and human workspace.

Confirm who can change the agent

Ask Sierra to show the controls your team receives.

Sierra’s Ghostwriter helps build agents from your materials and instructions. Simulations test behavior before changes go live. ^[1]^[1]

Sierra’s agent engineers also work with customers on setup. Confirm which changes your CX team can make directly and which need vendor support. ^[4]

Your team should be able to test the cases its policies depend on. Ask who approves changes before customers see them. See the four layers of hallucination defense. ^[5]

What to test in each option

Set priorities before testing. Use the same ticket sample and success criteria for every candidate.

Where your agents work

Does the product include their helpdesk or connect to one you retain? Test the handoff and include all required tools.

Price and billing unit

Model a full year at your normal and peak volumes. Include minimums, implementation and required add-ons.

Time to launch and reach your target

Ask how long setup takes and how results improve after launch. A launch date alone does not show steady performance.

Who writes and approves tests

Ask your CX team to create a test, change an instruction and review the result. Confirm permissions and vendor involvement.

Contract fit for your team

Check minimum commitments, billing terms and pilot conditions. Confirm the work your team must supply.

Include the cost of ongoing changes, not just initial setup.

Which option fits your team

Compare the support you need from the vendor as well as the product.

Sierra

Sierra fits teams keeping existing systems and wanting a vendor partner to build the agent. It supports voice and outcome-based contracts. Confirm rates, billing exceptions and control over changes. ^[2]^[3]

Decagon

Decagon lets CX teams describe workflows in everyday language. It also offers QA, experiments and simulations. Confirm engineering requirements for your internal systems and request a quote. ^[5]^[5]

Lorikeet

Lorikeet publishes plans and usage rates for structured workflows. Consider it for complex support while keeping your helpdesk. Verify included credits, required actions and voice costs. ^[6]^[6]

Fin (Intercom)

Fin lists $0.99 per outcome with a 50-outcome monthly minimum on another helpdesk. Some completed handoffs count as outcomes. Confirm your integration and roadmap requirements. See what the Fin acquisition means for support teams. ^[7]

Ada

Ada is worth evaluating for multilingual enterprise support. Ask for current pricing, implementation requirements and references at your volume. ^[8]^[9]

Richpanel

Richpanel combines AI and the human helpdesk. Annual pricing is $99/seat/month plus about $0.20 per AI conversation, with a $200 monthly AI minimum. Aeons resolves 63% of conversations automatically at 4.39/5 AI CSAT. Your team can write policy tests before rollout. See Aeons case study. ^[10]

Richpanel replaces your helpdesk and requires migration. Voice uses integrations with Aircall, Dialpad and JustCall. Confirm references at your scale and any custom connections.

How should I assess Sierra’s fit?

Ask for customer references with similar systems and channels. Review security, contract terms and rollout responsibilities. Funding and brand names alone do not establish fit.
