Siena AI

Siena AI is an empathic, autonomous AI customer service platform built specifically for direct to consumer ecommerce brands. Founded in 2023 by Andrei Negrau and Lisa Popovici, who previously built conversational commerce software for Shopify merchants, the company raised a four point seven million dollar seed round from investors including Sierra Ventures, Pari Passu Ventures, and Village Global. Around a hundred brands use it, skewing toward health, beauty, fashion, and lifestyle names like HexClad, Kitsch, Simple Modern, and Eight Sleep. Siena autonomously handles up to eighty percent of interactions across more than a hundred languages while matching a brand's voice.

The platform is built around CoRE, a Cognitive Reasoning Based Engine that replaces rigid branching tree logic with reasoning based decision making, weighing multiple factors in real time to resolve complex, multi intent messages. Rather than routing conversations to humans, Siena takes goals like editing a subscription or sending a replacement and autonomously executes every step, pulling data from connected systems, asking clarifying questions, and making updates. It embeds inside a brand's existing helpdesk such as Zendesk, Gorgias, Kustomer, Gladly, or Dixa, and connects through an app store to Shopify, subscription tools like Recharge and Skio, and Loop Returns.

Siena's signature is empathy and brand voice. Its AI Personas feature lets a brand create distinct personas that speak its voice across channels, for example a casual tone on social media and a more professional one over email. Coverage spans email, live chat, SMS, WhatsApp, and social media direct messages and comments, though not voice or phone. Customers report handling a majority of tickets while sustaining high satisfaction, with the vendor citing a customer satisfaction score around four point eight out of five across tens of thousands of surveys and an alignment score near ninety nine point seven percent.

Teams configure Siena through a well regarded admin interface, building an automation library and standard operating procedures, testing in a Playground, and refining personas before reaching full autonomy, typically over a six week enterprise blueprint rather than a same day setup. An Ask Siena tool surfaces conversational voice of customer insights that brands use for product and retail decisions. Pricing is sales led with a reported floor around seven hundred fifty dollars a month plus a per conversation rate, positioning Siena for mid market and enterprise brands doing meaningful ticket volume on Shopify.
