What Are Business Signals?
Business signals are publicly observable data points that reflect the current state and trajectory of a company. They include hiring activity, financial filings, leadership changes, operational expansion, strategic announcements, and regulatory events.
On their own, any single signal is ambiguous. A company hiring three new salespeople could mean many things. But when a company is simultaneously hiring salespeople, has just filed accounts showing 40% revenue growth, has appointed a new Commercial Director, and has just signed a new office lease — those signals together tell a clear story: this company is scaling aggressively and will need supplier support to do it.
This is the intelligence that BuyingWindow delivers: not raw signals, but the commercial interpretation of signal patterns — which companies are entering buying windows and why.

The Signal Hierarchy: Strength and Conviction
Not all business signals carry equal commercial weight. BuyingWindow categorises signals into three tiers based on their predictive value for buying behaviour. Higher-tier signals trigger more immediate opportunity scoring.
Tier 1 — High-conviction signals
Tier 2 — Supporting signals
Tier 3 — Context signals
How to Interpret Business Signals Commercially
The commercial interpretation of a business signal depends on what you're selling. A funding round means different things to a recruitment agency, an IT provider, and a commercial property agent. BuyingWindow' AI models are trained to interpret signals in the context of specific service categories, ensuring the opportunities surfaced are genuinely relevant to your business.
Same signal — different commercial interpretations

IT services provider
Infrastructure scaling needed — likely investing in cloud, security, and collaboration tools
Commercial property agent
Current premises likely undersized — office expansion probable within 6 months
Accountancy firm
Revenue recognition complexity increasing — audit and advisory readiness needed

Frequently Asked Questions
What are business signals?
Business signals are publicly observable data points that reflect a company's current state of change. They include hiring activity, financial filings, leadership appointments, operational expansion, regulatory events, and strategic announcements. When monitored in combination, business signals reveal commercial opportunities for B2B sales teams — indicating which companies are entering buying windows.
How are business signals different from buying signals?
Business signals are the raw observable data points (e.g. a company filed accounts showing 35% revenue growth, or hired a new CTO). Buying signals are the commercial interpretation of those business signals — the inference that this company is likely entering a buying window relevant to your specific service. Business signals are the inputs; buying signals are the outputs after AI analysis.
Where do business signals come from?
Business signals come from multiple sources: Companies House (filings, appointments, accounts), job boards (hiring patterns), LinkedIn (leadership changes, company updates), news databases (press releases, announcements), contract databases (public sector procurement), regulatory databases (planning applications, compliance filings), and industry-specific sources. The value comes from monitoring all these sources simultaneously.
What are growth signals?
Growth signals are business signals that specifically indicate a company is expanding. They include: significant revenue increases in filed accounts, multiple new hires in the same period, new premises or office expansion, new product launches, geographic expansion, strategic partnerships, and funding announcements. Growth signals typically indicate a company entering a buying window for services that support scale.
