Estera

Estera is an AI receptionist platform built by Estera AI LLC that handles inbound calls, WhatsApp conversations, and outbound prospecting automatically, around the clock. Founded by Craciun Andrei-Fredy and Toma Ioan-Rares, the product targets customer-facing businesses — particularly real estate agencies, hotels, restaurants, and medical practices — that lose leads to unanswered messages and missed calls. The platform claims a sub-5-second response time and support for 50+ languages, with a self-reported setup time of under 3 minutes.

What It Is

Estera is a multi-channel AI communication layer that sits between a business and its customers. It operates across three distinct products: Estera Voice (AI phone receptionist), Estera Concierge (WhatsApp automation), and Estera Messages (outbound WhatsApp prospecting). Together, these products are designed to ensure no inquiry goes unanswered, no lead goes cold, and human agents only engage when a conversation is already qualified and warm.

Three Products, One Platform

• Estera Voice — Answers every inbound call in under 5 seconds, takes messages, books appointments into a connected calendar, and speaks in 50+ languages. Higher-tier plans include multi-location call routing and live escalation to a human team member.
• Estera Concierge — Handles WhatsApp conversations automatically, replies instantly to inbound messages, detects customer intent, qualifies leads, and books appointments directly from the chat thread. It retains full conversation history for personalized follow-up.
• Estera Messages — Sends personalized outbound WhatsApp messages at scale to property owners or other target contacts, qualifies interest automatically, and hands off warm leads to human agents.

Target Industries and Workflow

Estera is explicitly configured for real estate, hotels and hospitality, restaurants, medical practices, law firms, travel agencies, salons, and auto centers. The workflow is designed to replace or supplement a human receptionist: the AI handles the first line of contact, qualifies the customer, and either books an appointment or escalates to a team member. According to vendor-published use cases, Neocasa Real Estate reported 100% of after-hours inquiries answered and a 55%+ increase in automatically booked viewings, while SkyLine Properties reported a 2× pipeline growth and a 31% outreach reply rate using Concierge and Messages together.

Setup and Integration

The platform advertises a no-code, 3-minute setup with no technical team required. Higher-tier plans include CRM integration (with an additional setup fee), API access for custom integrations, and a dedicated onboarding session. The platform is secured by Dodo Payments with AES-256 encryption for payment processing. Support escalates from email-only on the entry tier to priority phone, email, and WhatsApp support on the top tiers.

Multilingual and Availability Capabilities

Estera supports over 50 languages with no additional configuration required, making it suitable for businesses serving international customers. The platform is available 24/7 including weekends and holidays, and can handle 30+ simultaneous calls and unlimited simultaneous WhatsApp conversations according to the vendor's own comparison table.

Current Status

Estera is actively live as of 2026, with published use cases dated March–April 2026 and a Trustpilot rating of 4.3 out of 5. The company is incorporated as Estera AI LLC and operates a multilingual website covering English, Romanian, German, Polish, French, Italian, and Spanish markets.
