Siena, the AI-driven customer experience platform trusted by hundreds of leading consumer brands to automate customer interactions and turn them into meaningful relationships, today announced the close of a $17 million Series A led by York IE, with participation from Joyance Ventures and existing investors Aglaé Ventures and Sierra Ventures. This investment brings Siena's total funding to $29.7 million. Funding will expand shared infrastructure consumer brands use to support sell to and understand customers.
Siena's Shopping Agent and Social Agent work around the clock, answering questions, recommending products and closing purchases directly inside a conversation. On social, that includes moderation, community engagement and customer support across comments and DMs, including product questions under paid campaigns. Siena's voice agents draw on the same customer context. A shared inbox lets human and AI teams work side by side. Enterprise controls include A/B testing on live traffic, a Quality Suite that grades agent performance and Autopilot to help build agents faster.
Hundreds of consumer brands, including FIGS, SPANX, Comfrt and HexClad, currently work with Siena. Across its customer deployments, Siena automates up to 80% of customer interactions. Examples of customer results include:
Eskiin's Social Agent lifted weekly comment engagement by 50% and freed up 15 hours a week for its social lead.
Coterie turned a customer-analysis project that used to take weeks into a ten-minute query with Ask Siena, using it to analyze customer feedback.
At SPANX, Siena Intelligence traced a spike in shipping complaints to a single carrier issue affecting nearly every delivery in one region, helping the team pinpoint the fix quickly.
"Siena is rebuilding the customer experience stack around customer intelligence, connecting how brands serve, sell to and retain their customers," said Tom Holahan, General Partner, York IE. "We believe Siena can become as essential to running a brand as its commerce platform."
Siena's Agent of Record platform brings together and enriches conversations, orders, subscriptions, reviews, loyalty data and brand knowledge in Siena Intelligence. A customer's explanation for returning a product can inform their next shopping recommendation. Across customers, those explanations can reveal a recurring product issue.
"We started by helping brands take care of their customers," said Andrei Negrau, cofounder and CEO of Siena. "Today, brands use Siena to help customers buy and guide decisions across the business. When an agent learns why someone buys or leaves, that understanding should travel with the customer and reach the people running the brand."
