Siena AI

Siena AI builds AI customer service agents for retail and e-commerce brands, positioned as an Agent of Record. Siena's own pricing page, published October 20, 2026, says to tell us what you need and we'll send pricing that fits, and shows a $750 a month platform fee covering the core AI engine and an unlimited sandbox, plus an Automation Pack at $0.90 per automated ticket. Support and implementation carry no price, covering expert onboarding and dedicated Slack support. The page mentions no free tier or trial, and the homepage shows no pricing. Third-party sources agree on the $750 plus $0.90 structure, with one noting the final quote is settled on a sales call and another that the page is a guided calculator.

On funding, a $17 million Series A was announced on October 6, 2026, led by York IE with Joyance Ventures, Aglaé Ventures and Sierra Ventures participating, and the company says total funding is $29.7 million, with an earlier $4.7 million seed in November 2023 reported by one guide. One report says several capabilities remain in early access and a native help desk is still planned, so Siena sits on top of existing helpdesks such as Gorgias and Zendesk. Per-ticket pricing makes costs scale with automation volume, so a shop with 10,000 automated tickets would pay about $9,750 a month before onboarding.

Siena AI suits e-commerce brands wanting AI agents on top of their existing helpdesk. Compare Lorikeet, Capacity and Helpshift. Browse the Customer Support tools directory for more.
