24/7 AI Lead Qualification
for Your Alto Agency
Alto manages your pipeline. Lead Flow handles contacts already inside it. But 40% of enquiries arrive at night — and those leads never enter Alto at all. Sift qualifies them on your website the moment they land.

Two layers. No gaps.
Alto agencies that close the most leads use Sift and Lead Flow as complementary stages of the same funnel — one before the CRM, one inside it.
Lead Flow only activates for contacts already inside Alto — Sift captures the ones that never got there.
How Sift works alongside Alto
Buyer lands on your website
Sift's widget is on your agency site — it responds instantly, any time of day. No one needs to be at a desk.
GDPR consent captured
Before any personal data is collected, the buyer consents. Full ICO audit trail stored automatically — no manual record-keeping required.
AI qualifies the buyer
Chain status, Decision in Principle, buyer scheme eligibility, budget, and timeline — in plain conversation, not a form.
Hot leads in your Sift dashboard
Scored, ranked, and ready. Your team reviews overnight leads before the first viewing of the day.
Leads land in your Sift dashboard
Export via CSV at any time, or configure an outbound webhook on Growth/Scale plans to forward leads to a URL of your choice. Native Alto integration is on the roadmap.
What Sift captures for each lead
Plus: full conversation transcript, GDPR consent record, and contact details — stored in the Sift dashboard, exportable via CSV, and forwardable to an outbound webhook (Growth/Scale).
Why Alto agencies are adding Sift
Lead Flow works in Alto. Who works on your website?
Lead Flow qualifies and nurtures contacts already inside your Alto pipeline. It can't respond to a buyer who enquires at 11pm before submitting any details. Sift handles that stage.
Works with or without Lead Flow
Some Alto agencies run Sift alongside Lead Flow as two complementary layers. Others use Sift standalone. Either way, there's no platform migration, no Alto configuration changes, and no shared data conflicts.

Frequently asked questions
Does Sift integrate with Alto CRM?
Qualified leads land in the Sift dashboard with full conversation transcript, GDPR consent record, lead score, and contact details. Export via CSV at any time. On Growth and Scale plans, leads can also be forwarded to an outbound webhook URL of your choice. Native integrations with leading UK estate agent CRMs — including Alto — are on the roadmap.
How is Sift different from Alto Lead Flow?
Sift and Alto Lead Flow solve different problems. Sift is a website chat widget that qualifies buyers before they ever enter Alto — capturing enquiry data 24/7 and storing structured records in the Sift dashboard. Lead Flow operates inside Alto, managing and automating workflows for leads already in your pipeline. Sift is pre-CRM; Lead Flow is in-CRM. Most Alto agencies use both.
Do I need to choose between Sift and Alto Lead Flow?
No — they are designed to work together. Sift qualifies buyers on your website; leads land in the Sift dashboard and can be exported via CSV or forwarded to an outbound webhook on Growth/Scale plans. Lead Flow then manages those records inside Alto. Running both means the entire buyer journey is covered: from first website enquiry through to pipeline management.
Will Sift work alongside Alto's other features?
Yes. Sift runs independently as a website chat widget — it does not interfere with Alto's modules, workflows, or existing data. Your Alto setup stays exactly as it is; Sift just adds a 24/7 pre-qualification layer on your website, with leads accessible via the Sift dashboard, CSV export, or outbound webhook.
What does Sift cost for an Alto agency?
Sift is priced from £149/month (Starter) to £549/month (Scale), with all plans including the web chat widget, CSV export, and a 14-day free trial — no card required. Growth and Scale add an outbound webhook for forwarding leads. Annual billing saves two months.
