Signal vs Cognism · London

A Cognism alternative — when the question is “when”, not “who”.

Cognism is a very good contact database: verified emails and mobiles for almost anyone. But it can’t tell you which of those companies is nine months from an office decision. Signal answers the timing question — for London office change specifically.

Side by side

Different tools, different questions.

Cognism Signal
What it is B2B contact database — emails, mobiles, firmographics for millions of companies. Office-change intelligence — which London companies are about to move, refit or refurbish, and when.
The question it answers “Who is this company and how do I reach the right person?” “Which companies should my BD team call this quarter — and why now?”
Timing Static — every company, all the time. Intent add-ons track topic research, not physical office events. Event-driven — lease expiries, breaks, planning applications, filings, hiring. Scored 0–100, re-run weekly.
Coverage Global, all industries. London office occupiers, purpose-built for firms that win work from office change.
Contacts Core strength — verified at massive scale. Included per lead (compliant B2B sources), but the timing is the product.
Best for Outbound teams that already know who to target. Fit-out, design, agency, furniture, relocation and FM teams that need to know WHO to target and WHEN.
Honestly, though

Plenty of our clients run both: Signal decides who this quarter’s hundred calls are; a contact database deepens the org chart once a pursuit is live. If you can only run one for office-change BD, run the one that knows about the lease.

FAQ

Questions, answered.

Is Signal a replacement for Cognism?+
Only if your market is London office change. Cognism is a general-purpose contact layer; Signal is a timing layer for one market. For fit-out, workplace design, agency, furniture, relocation and FM BD, Signal replaces the guesswork — and still hands you a named contact per lead.
Does Signal include contact details?+
Yes — each lead carries a named decision-maker with phone where available, sourced from compliant B2B providers under a legitimate-interest basis. The difference is you get contacts for companies that are actually in market, not a directory.
What does Signal cost compared to a database seat?+
A £1,000 30-day pilot, then £2,500/month for London coverage (plus setup). Comparable to a couple of database seats — for a scored list of companies in a decision window rather than a searchable directory.
