transaction coordinator that helps buyers, sellers, and their agents move from “under contract” to “closed” with fewer errors, less busywork, and clearer communication. Doorbis automatically builds and tracks transaction timelines, monitors contingencies and deadlines, drafts client communications, and keeps all parties in sync across AI-driven SMS, WhatsApp, email, LINE, messenger, Telegram, voice, and client and partner web portals.

Under the hood, Real Agentic AI combines frontier LLMs, real-time multilingual AI voice Q&A, retrieval-augmented generation (RAG), multi-agent orchestration, and proprietary analytics on a multi-tenant, RLS-protected, cloud-native SaaS architecture, all supervised by licensed human brokers for legal and regulatory compliance. The Doorbis platform is integrated with industry partners, including a licensed California real estate brokerage. The company also focuses on fairness and transparency, using its IP and a planned membership-style model to reduce bias and make pricing and engagement more predictable for consumers.

Real Agentic AI operates as a privately held subsidiary of Kossel Corp., with a long-term roadmap from transaction coordination to a fully agentic, broker-supervised AI brokerage—built to scale from local neighborhoods to global real estate markets.
