Siena AI sells empathy at scale, which sounds like marketing until you watch most support bots talk. Founded in 2022 by Romanian entrepreneurs Andrei Negrau and Lisa Popovici, whose previous startup was SMS-commerce company Cartloop, Siena builds autonomous customer service for e-commerce and consumer brands with an unusual obsession: sounding like the brand, not like a template. Its AI personas carry a defined voice and tone, and brands like Spanx, HexClad, Kitsch, Prose, and MUD WTR use them to resolve orders, subscriptions, and returns across email, chat, SMS, and social DMs without the customer feeling the switch to a robot.
Under the personality is a full commerce-support engine. Siena sits on top of the help desk you already run, Gorgias, Zendesk, Kustomer, or Gladly, and plugs into Shopify, Recharge, Klaviyo, and the rest of the DTC stack to take real actions. It claims up to 80 percent automation with CSAT going up rather than down, and rounds the platform out with automated QA scoring, a voice-of-customer topic explorer, and an AI shopping agent that recommends products mid-conversation.
The company raised a $4.7 million seed led by Sierra Ventures in 2023 and publishes its pricing shape: a $750 monthly platform fee plus about $0.90 per automated ticket, with volume pricing quoted.
Choose Siena when brand voice is a genuine business asset, the common case for DTC brands whose customers chose them partly for the vibe. If you just need cheap deflection, simpler tools cost less; if every customer touch is brand equity, Siena is the one built around that belief.
