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.

Zowie is an AI agent built for online retail, and it is unusually comfortable wearing two hats at once. On the support side it resolves high-volume questions like order status, returns, and product availability across chat, email, and voice, claiming to automate a large majority of tasks in as many as 175 languages without wandering off into hallucination. On the sales side it goes where few support tools dare, running sales playbooks, recommending products, and guiding shoppers all the way to checkout inside the same conversation. An AI Copilot backs up human agents, and the whole thing plugs into Shopify, Magento, and Klaviyo.
The company's journey is a good one. It was founded in 2018 by Maja Schaefer and Maciej Ciolek, began life in Poland under a different name, and has since planted its headquarters in New York with backing from Tiger Global and Gradient Ventures, among others. That treating-support-as-a-revenue-channel angle is Zowie's signature move, and it is what separates the product from the many tools that only ever think about deflection.
Zowie deploys either on top of your existing help desk or as a standalone, and it recently landed on the Google Cloud Marketplace, a sign of its push toward larger, more demanding customers. Pricing is annual and outcome-based, structured around the work the agents actually deliver rather than a per-seat sticker, so expect a tailored quote rather than a public price list.
Brands like InPost, Decathlon, and GetYourGuide have put it to work across both support and commerce. If you run an e-commerce operation and want an AI agent that not only clears the ticket queue but also quietly nudges revenue upward while it is at it, Zowie's unusual dual focus on both resolving problems and selling products makes it a genuinely distinctive option that is well worth testing.
