If you run a UK estate or lettings agency and you are choosing a WhatsApp platform, Stitch and SalesRook are two names that come up quickly. Both are UK companies, both connect WhatsApp to property CRMs, and both use automation to reply to enquiries faster. They solve slightly different problems, though, and the best fit depends on how your branches work today.
This comparison sets out what each platform is built around, where they overlap and the questions worth asking in a demo. If you would rather see Stitch working on your own CRM, you can book a demo and we will walk through it with your team.
SalesRook is a London PropTech company founded in 2022 that builds AI for estate agents and mortgage brokers. Its product handles property enquiries over WhatsApp and connects to agency CRMs, starting with a Reapit integration launched in late 2022.
In a January 2025 announcement, SalesRook reported 127% software revenue growth in 2024, more than 50,000 WhatsApp messages processed each week and support for more than 125 offices. The company also said about 40% of client engagement happens outside office hours, which is a large part of its pitch: an AI layer that answers when the office is closed.
Stitch is a UK WhatsApp Business Platform provider and Meta Business Partner. We built msgboxx, a WhatsApp team inbox on the official WhatsApp Cloud API, available as a web app, a Chrome extension and a mobile app.
For agencies, the core idea is that WhatsApp becomes a company channel. Every branch number sits in one place, conversations are assigned to negotiators, and the history stays with the business when staff move on. Automation and AI persona bots sit on top of that inbox, handling first replies and qualification before a person takes over. Our guide to centralising WhatsApp for estate and lettings agents explains why that matters for compliance.
The main difference is emphasis. SalesRook leads with AI enquiry handling. Stitch leads with a shared, compliant team inbox and adds automation to it.
Both are designed to cut response times on portal leads, so test them with your own enquiry flow rather than relying on headline numbers. Ask each provider to show a live Rightmove lead arriving, the first WhatsApp message going out and the handover to a negotiator.
Response speed matters. Our own estate agent response time study mystery-shopped 154 enquiries and found sellers waited around five hours on average for a reply. Whichever platform you choose, the gain comes from removing that delay.
For most agency directors, compliance is the deciding factor. Personal WhatsApp on negotiators' phones leaves the business with no record and no control when someone leaves.
Stitch runs on the official Cloud API, keeps conversations in a business-owned inbox and lets administrators export full chat histories in CSV format for audits and subject access requests. When you speak to any provider, ask:
Our article on UK GDPR and data residency for WhatsApp messaging goes into the detail.
SalesRook will appeal to agencies that mainly want an AI assistant answering portal and out-of-hours enquiries, especially Reapit users who want something focused on that job.
Stitch suits agencies that want WhatsApp run as a proper company channel across every branch: one inbox, CRM-linked messaging, broadcast campaigns to landlords and applicants, and AI on top. It also suits groups that mix sales, lettings and property management teams who all need access to the same customer history.
