Siena Call Center AI Software
About Siena
Siena builds AI agents for consumer brands and describes its platform as the Agent of Record. Co-founders Andrei Negrau, the CEO, and Lisa Popovici, the President, started the company in 2023 with an empathic customer service agent for ecommerce support. Siena says it now works with hundreds of brands and has automated hundreds of millions of customer interactions, with up to 80% of interactions automated across deployments. As customers asked for help beyond tickets, Siena added a Social Agent for comments and DMs, a Shopping Agent that recommends products and completes purchases in the conversation, voice agents, and review and retention tools. The core argument is that a brand's ERP, storefront, loyalty, and subscription tools each record a transaction, but none record the relationship. Siena Intelligence joins conversations with orders, subscriptions, reviews, loyalty data, and brand knowledge, and Siena Memory carries that context across channels. Teams can query it through Ask Siena in the web workspace or Slack, and other tools can reach it through MCP. Enterprise controls include A/B testing on live traffic, a Quality Suite, and Autopilot. In October 2026 Siena closed a $17 million Series A led by York IE, with Joyance Ventures and existing investors Aglaé Ventures and Sierra Ventures, for total funding of $29.7 million. Named results include Eskiin, whose social engagement rose 50%, and SPANX, where Siena traced a spike in shipping complaints to one carrier.
