European B2B buying signals and where to find them free

A buying signal is a dated public event that raises the odds a company needs what you sell. Most sales teams use two of them, both bought from a vendor, both stale. Europe publishes dozens for free, and the good ones sit in registers and portals that no lead database bothers to index.

This is a catalogue of the signals we use, what each one proves, where to get it, and how fresh it stays. Use it to pick one signal that fits your offer rather than layering five that do not.

Signals from company registers and filings

Register events, free or near-free across most of the EU
Event	What it suggests	Where	Useful for
New company incorporated	Everything is unbought	Companies House, SIRENE, KRS, Registrų centras	Accounting, banking, software, insurance
Foreign parent registers a subsidiary	Market entry in progress	National registers, filter on foreign director address	Advisory, recruitment, logistics, local marketing
Director or officer change	New person, new mandate, 90-day window	Register change feeds	Anything the new role owns
Share capital increase	Money arrived	Register filings	Capital equipment, hiring, expansion services
Registered address change	Move, growth or consolidation	Register filings	Facilities, IT, fit-out, relocation services
Late accounts filing	Finance function under strain	Register status flags	Outsourced finance, systems
New branch or establishment	Physical expansion committed	SIRENE establishments, KVK, national equivalents	Local suppliers of every kind

The foreign subsidiary signal deserves special attention for anyone selling services to incoming companies. A Japanese parent registering a Dutch BV in March will spend the next twelve months buying accountants, lawyers, recruiters, offices, insurance and marketing. That company did not exist as a prospect in February and no database has it yet.

Signals from hiring

Job adverts are the freshest public signal available and the most misread. An advert proves the company needs a person. Whether it proves they need a supplier depends entirely on what you sell.

Reading a job advert correctly
The advert	What it proves	Who should act on it
First-ever role in a function	The function is being built now	Anyone selling into that function
Role open more than 60 days	They cannot fill it	Recruitment, outsourcing, automation
Five roles in one team at once	Funded growth	Systems that break at scale, training, facilities
Named tool in the requirements	Verified technographic with a date	Complements and competitors of that tool
Role in a new country	Market entry, before the entity exists	Entry advisory, payroll, local marketing
Compliance or regulatory role	A deadline is driving them	Compliance tooling and advisory

Sources: national employment services publish free feeds in several countries, and company career pages are crawlable. A role posted in the last 21 days is a live signal. At 90 days it is either filled or abandoned, and either way your opener is wrong.

Signals from public procurement

TED, the EU tenders database, publishes every above-threshold public contract notice and award in the union. It is free, structured, and almost nobody in B2B sales reads it.

Three ways to use it. A published tender tells you a buyer has budget and a deadline. An award notice tells you who won, what they charge and when the contract ends, which gives you a dated opening two years out. A repeated award to the same supplier tells you where an incumbent is vulnerable.

National portals below the EU threshold carry the smaller contracts, and those are where a mid-sized supplier actually competes.

Signals from regulation and sector data

These are the strongest signals available because they carry a date the buyer cannot move.

CSRD reporting waves. Companies crossing the size thresholds must report to a timetable set in law. Anyone selling sustainability data, assurance or reporting software has a list with dates attached.

Sector authorisations and licences. Food business registrations, transport operator licences, financial services authorisations, medical device registrations. Each national authority publishes a list, each entry is dated, and a new authorisation means a company just started doing something.

Energy and infrastructure registers. Planning consents, grid connection applications and renewable project registers all publish forward-looking project pipelines with locations and dates.

Customs and trade classifications. Where published, these show who imports what from where, which is the cleanest possible signal for anyone selling an alternative supply route.

A regulatory deadline beats every behavioural signal, because it answers the "why this week" question without you having to manufacture urgency. The buyer's calendar already contains the date.

Signals from the company's own publishing

Website changes, pricing page edits, new case studies, new integrations, a careers page appearing in a second language, a new locale on the site. Each of these is a decision somebody made and paid for in the last quarter.

These require you to crawl and diff rather than to query, which is why databases do not sell them and why they stay uncontested. A company that added a German language site last month is entering Germany, and nobody else on your competitor list knows it yet.

How to pick your signal

Answer three questions in order.

What does the company do differently the week after this event? If nothing changes in their buying behaviour, it is not a signal, it is a firmographic.

How long does the window stay open? A funding round buys six months. A job advert buys three weeks. A regulatory deadline buys until the deadline. Your cadence has to fit the window or you arrive after the decision.

Can you say it out loud in the first line without sounding like surveillance? "You posted a compliance role in Munich three weeks ago" is fine, it is a public advert. "Your head of finance visited our pricing page" is not, and the reaction to it costs you the account.

The mistake worth avoiding

Stacking signals until the list is empty. Companies that raised funding and posted a role and changed a director and appear in a tender: there are four of them in Europe and none of them need you.

One well-chosen signal, applied across a properly defined universe, produces a list of the right size with a first line that is true. That is the whole method.

Ripe Leads builds lists from dated signals, not from dropdowns

Ripe Leads is KoFi Tech's outbound arm. It picks the signal that matches what you sell, pulls it from the register or portal that publishes it, and keeps the window fresh so the first line is still true when the email lands.
