Signalbase Real-Time Merger & Acquisition Signals

Real-time M&A signals across the full deal lifecycle, from early rumors and social media hints to fully announced deals with acquirer details and amounts. Detect mergers, acquisitions, and consolidation activity within minutes of the original signal, with company context, deal details where available, and original source attribution.

18k+ M&A signals detected and growing every minute. Used inside data vendors, GTM teams, and platforms running competitive intelligence and signal-based outbound on companies in transition.

Why this beats most M&A databases

Most M&A data products (PitchBook, Crunchbase, Mergr) catch deals only after public announcement, usually days or weeks late, with no early warning. We catch the full lifecycle, from the rumor on LinkedIn to the press release.

• Detection in under a minute. From original signal (news, press release, social media, LinkedIn post) to API response in less than 60 seconds.
• Full deal lifecycle. Early rumors, hinted activity, and announced acquisitions, all source-attributed and timestamped. Filter for confirmed deals only when you need them.
• Company context out of the box. Every signal includes industry, country, employee count, founded year, LinkedIn, for the target company, and for the acquirer when known.
• Filterable by what matters. Country, industry, category, date range, and free-text search.

By the time PitchBook updates, the deal is old news. We surface it the moment the first signal hits the wire.

Built for

• B2B sales and outbound teams prospecting on companies in transition. Acquired companies are about to consolidate vendors, switch tools, and rationalise budgets
• Competitive intelligence teams monitoring M&A activity in their market and adjacent categories
• AI SDR and GTM platforms triggering outbound when target companies are acquired or acquire others
• Investment research and corporate development tracking deal flow and consolidation patterns
• B2B data vendors enriching company records with M&A status as a state-change indicator
• Investors and analysts tracking sector consolidation and roll-up activity

FAQ

How is this different from PitchBook, Crunchbase, or Mergr? Those products are databases that update after deals are announced, usually with significant lag. We're event infrastructure that catches M&A activity from the original signal source (news, press releases, social media, LinkedIn) within minutes. If you need the deepest historical M&A archive, use a database. If you need to know when a deal happens as it happens, use Signalbase.

Why are some records missing acquirer details or deal amounts? We catch the full M&A lifecycle, from early rumors and social media hints to fully announced deals. Early signals often surface before the acquirer is publicly named or the deal value is disclosed. Filter for records where acquiringCompanyName is not null if you only want confirmed deals.

Can I filter to only confirmed acquisitions? Yes. Filter for records where acquiringCompanyName is not null. For ongoing monitoring of confirmed deals with webhook delivery, the direct Signalbase platform is a better fit. Get in touch at trysignalbase.com.

Can I monitor M&A activity in a specific industry or country? Yes. Use countries for geography and categories or search for industry and sector filtering.

How do I avoid alerting on the same deal twice? Every signal has a unique signalId. Deduplicate on this field across runs. Note that an early rumor and a later official announcement may have separate signal IDs if they originate from different sources.

Can I get webhooks or higher volume? Yes, on the direct Signalbase platform. Apify is great for evaluation; production-grade trigger workflows with webhooks, custom signal taxonomies, and dedicated rate limits live on the direct plan. Production access starts with a paid pilot scoped directly with the founding team. Get in touch at trysignalbase.com.

The underlying Signalbase API has rate limits. If you hit a 429 response, wait a few seconds and retry.
