What Is a Sales Tech Stack? How to Choose Yours
Stop buying tools on hype. Learn how to choose a sales tech stack that connects - five criteria, a stack health check, and 1,000+ tools compared.
Nesti runs AI voice agents, WhatsApp automation, and avatars to handle every inbound enquiry an estate or letting agency receives — answering calls, qualifying callers, routing to the right person, booking viewings, and syncing transcripts to a CRM in real time. It is built for mid-market and enterprise agencies, from busy multi-branch independents to national franchise networks. The standout capability is caller memory: Nesti recognises returning callers, recalls previous conversations, and surfaces unlinked enquiries — so no lead falls through the cracks across channels. Pricing starts at £199 per branch per month, which adds up quickly across a large estate agency network, and there is no public API, meaning teams that want to embed Nesti into a broader automated workflow will hit a hard wall.

Nesti is a vertical sales assistant built specifically for property agencies — it does one thing (inbound enquiry handling) and goes deep on it, which makes it a credible fit for mid-market and enterprise agency groups that are losing leads to missed calls and slow follow-up. On the agentic readiness front, there is no public API and MCP status is unknown, so you cannot drive this from an external AI agent or orchestration layer without scraping — it is UI-only for now, which is a real constraint if you are building a broader agentic stack. At £199 per branch per month on the entry tier, costs scale fast across a multi-branch network, so budget for an experienced operator to configure it properly — vanilla setup will leave value on the table. The honest limitation is scope: Nesti is purpose-built for inbound property enquiries, so if your agency needs outbound sequencing, deep reporting, or custom workflow automation beyond CRM sync, you will need to bolt on additional tooling.
