Bulutfon vs Yellow.ai

Bulutfon is a Turkish cloud phone system, often called a virtual PBX or bulut santral, built for small and mid-sized businesses in Turkey. Instead of buying and maintaining switchboard hardware in the office, companies get their phone numbers, call routing and reporting as a subscription service that works over the internet on desk phones, computers and mobile phones.

Businesses can use local geographic numbers and 0850 numbers, set up IVR menus that greet callers and route them to the right department, create call queues and ring groups, record calls, and receive voicemail by email. Employees answer calls from desktop and mobile softphone apps or IP desk phones, so remote and field teams stay on the same number. A web panel shows call reports, missed calls and agent performance, and integrations with CRM and help desk tools display caller details and log calls automatically, with an API for custom connections. Bulutfon operates under authorization from Turkey's telecom regulator (BTK) and is priced in Turkish lira per user or package.

Bulutfon fits Turkish SMBs, e-commerce companies, clinics, agencies and support teams that want a professional phone setup quickly and without hardware. Call recordings contain personal data, so businesses should handle them in line with KVKK. Local competitors such as Verimor and Netgsm offer similar cloud PBX services, while international VoIP tools like Aircall and Dialpad have richer integrations but weaker support for Turkish numbers, local billing and regulation.

Yellow.ai is an enterprise conversational and agentic AI company founded in 2016 in Bengaluru, India, as Yellow Messenger by Raghu Ravinutala, Jaya Kishore Reddy Gollareddy and Rashid Khan, and now headquartered in San Mateo, California. It builds AI agents that resolve customer and employee requests across chat, voice and email for large companies in banking, retail, healthcare, utilities and the public sector, and says it serves 650+ enterprise brands.

Its current platform, Nexus, is used to design, deploy and monitor fleets of AI agents with access to 15+ LLMs, 150+ prebuilt integrations (Salesforce, Zendesk, Genesys, NICE and others) and 35+ channels including WhatsApp. Nexus VOX handles voice calls in 500+ languages, and Nexus EDGE brings agents to the employee desktop with human approval on each action. Pricing has two tiers: a free plan with one agent and 500 sessions a month, then $0.99 per resolution, and custom Enterprise contracts.

Yellow.ai fits large contact centers that need voice plus chat automation, many languages and strict compliance (SOC 2 Type II, ISO 27001, HIPAA, PCI-DSS). It is too heavy and sales-led for a startup adding a help-center bot; Intercom Fin is simpler inside Intercom, and Voiceflow or Botpress give product teams more hands-on control at lower cost.

Recent development: on August 3, 2026 Yellow.ai agreed to go public through a merger with Bluerock Acquisition Corp., a SPAC, at a pro forma equity value of about $550M, with plans to trade on Nasdaq as YAI. Ask about contract terms and roadmap continuity during the transition.
