AloTech
AloTech is a Turkish cloud contact center platform founded by Cenk Soyak and İdris Avcı and selected as an Endeavor company in 2014. Outside Türkiye it sells the same product as Call Center Studio, running on Google Cloud. It replaces on-premise call center hardware with a browser-based system for inbound and outbound calls plus written channels.
Voice features include ACD, CTI, IVR, speech recognition and text-to-speech, number masking, predictive, preview and IVR dialers, answering machine detection and call and screen recording. Written channels cover web chat, WhatsApp, Facebook Messenger, Telegram, SMS, email and video calls. An AI layer adds AI Maestro, agent assist, AI-based quality scoring (CX Quality), CX Insights and accent neutralization. Pricing is per user per month in Turkish lira with no long-term commitment: a cheaper written-only package and a full voice plus written package.
It suits Turkish companies running 10 to several hundred agents, from e-commerce support teams to outsourcers. Bulutfon and Verimor are lighter, cheaper virtual PBX options for small offices; Zendesk and Freshdesk are ticketing tools that AloTech complements through its Zendesk CTI app. Genesys and Five9 compete for large global deployments.
AloTech reports 650+ customers, 20,000+ users and over 65 million call minutes a month, with ISO 27001:2022 and ISO 42001:2023 certificates. Call Center Studio partnered with Globe Business in the Philippines in November 2025, and in October 2026 Parloa named AloTech its strategic AI partner in Türkiye.
Sierra
Sierra is a conversational AI platform that lets large companies deploy branded AI agents for customer service and sales. It was founded in San Francisco in 2023 by Bret Taylor, former co-CEO of Salesforce and chair of OpenAI's board, and Clay Bavor, a longtime Google executive. Its core job is resolving requests end to end, such as changing an order or rebooking a flight, by taking actions in the company's systems rather than just answering FAQs.
Teams build agents in Agent Studio or let Ghostwriter create one from SOPs, transcripts or recordings. A single agent can run across chat, SMS, WhatsApp, email, voice and ChatGPT. Horizon plans multi-step outcomes over days or months, and Insights adds conversation analysis, monitors, experiments and observability. There are no public plans: Sierra sells enterprise contracts with outcome-based pricing, so you pay for resolved conversations or other agreed results.
Sierra fits large consumer brands with high contact volumes and complex back-end systems; customers shown on its site include SiriusXM, Rocket Mortgage, Gap, Wayfair, SoFi and Vanguard. It is not built for small businesses that want a self-serve chatbot. Intercom Fin is easier to switch on inside an existing help desk, Ada targets a similar enterprise buyer with a longer track record, and Yellow.ai is strong in Asian and multilingual markets.
Sierra is growing fast: it reported $100 million in annual recurring revenue in November 2025 and raised $950 million in 2026 at a reported valuation above $15 billion. Expect a sales-led process and a scoped pilot first.
