Callsy isn't a single chatbot — it's a workforce of AI voice agents, each with a name, a voice, and one specialized job. One agent recovers abandoned carts, another confirms COD orders, another handles upsells, win-backs, bookings, or payments. They work by phone, SMS, and email, in your brand voice, around the clock, and they share a memory of every customer. You hire the roles you need, plug in your stack in five minutes, and see the exact revenue each agent brings back.
Most AI callers do one thing on one channel and take weeks to set up. Callsy goes live in five minutes, runs dozens of agent roles across phone, SMS, and email, and speaks 60+ languages with 100+ region-tuned voices — not robotic, but tuned per role and accent. It connects to Shopify, WooCommerce, Klaviyo, and Omnisend in one click, attributes every conversation to revenue, and starts at €49/mo with no contracts and a 30-day payback guarantee. Merchants report up to 34x ROI and cart recovery as high as +32%.
DTC and ecommerce brands are the core audience — Shopify and WooCommerce stores losing revenue at checkout, on COD orders, and in post-purchase follow-up. Beyond ecommerce, Callsy also serves SaaS companies and service businesses that need inbound lead qualification, appointment booking, payment recovery, and customer win-back. In short: any business with repetitive phone, SMS, or email conversations that directly affect revenue.
Callsy was founded by Arunas Vismantas and Laimonas Sutkus. Talking to D2C founders, they kept hearing the same problem: revenue leaking at checkout, and email recovery had plateaued. Voice was the obvious next channel, but human call centers were too slow and expensive to make it work. AI finally made the unit economics viable — so they built a platform where brands could hire AI voice agents the way they'd hire staff, live in minutes and cheaper than a part-time employee. Callsy is backed by 500 Global and Firstpick VC.
Callsy is built on conversational AI and large language models for natural dialogue, real-time speech-to-text and text-to-speech for human-like voice, and custom voice tuning across 100+ voices and 60+ languages. The platform layers in telephony and messaging infrastructure for phone, SMS, and email, one-click integrations with Shopify, WooCommerce, Klaviyo, and Omnisend, plus webhooks and API/MCP access. Data handling is GDPR-compliant, TCPA-compliant, and EU-hosted.
