VILNIUS, Lithuania, July 24, 2026 - Callsy.ai, the European AI voice agent platform for e-commerce, today announced that it has recovered €1,168,407 in revenue for online retailers through autonomous, AI-powered customer conversations. Backed by global accelerator 500 Global and Baltic venture firm Firstpick, Callsy is changing how e-commerce brands approach abandoned cart recovery, lead qualification, and customer follow-ups.
The company was founded by five-time entrepreneur Arunas Vismantas, who serves as CEO, and Laimonas Sutkus, who serves as CTO. Together they built a platform of AI voice agents that call, text, and email customers automatically, recovering sales that would otherwise be lost. To date, Callsy has powered more than 76,000 customer conversations across the e-commerce, healthcare, and SaaS sectors, with an average response time of just 47 seconds.
"Every abandoned cart is a conversation that never happened," said Arunas Vismantas, CEO and Founder of Callsy. "We built AI voice agents that pick up that conversation instantly, in the customer's own language and at any hour, and turn lost carts into recovered revenue. Our brands are seeing returns they simply could not reach with email alone."
Proven results for online retailers
Callsy's AI agents have delivered measurable returns for e-commerce brands around the world. AmourLinen achieved a 34x return on its investment, TrySculptique reported a 30x return from day one, and Neurogena generated more than $40,000 in additional revenue. The platform holds a 5.0-star rating on the Shopify App Store and currently runs 217 active AI agents for more than 261 brands across 12 countries.
Built for scale, speed, and compliance
Callsy supports more than 66 languages with region-specific accents and offers six specialized agent roles: Cart Recovery, Inbound Sales, Booking, Win-back, Payments, and NPS Feedback. One-click integrations with Shopify, WooCommerce, Klaviyo, Omnisend, and HubSpot allow merchants to go live in under five minutes.
The platform is GDPR-ready, TCPA-compliant, and hosted in the EU, with SOC 2 certification in progress. This gives brands enterprise-grade AI customer engagement without adding compliance risk.
Growing recognition
Callsy was recently named the number three Top Company in AI by F6S in March 2026 and was a finalist at Latitude59. The company also appeared on Shark Tank Lithuania, known locally as "Rykliai. Lietuva," on TV3.
