Societeinfo Alternatives: The B2B Enrichment Comparison (2026)

Societeinfo is an excellent source of legal data on French companies, built on official registers (INSEE, BODACC, INPI) with a solid API. But its scope is exclusively French. Here's an honest overview of Societeinfo and its alternatives.

What is Societeinfo?

Societeinfo is a B2B data platform focused on completeness and API access, built on official French registers (INSEE, BODACC, INPI). Licensed by INPI and INSEE, it covers the 11M companies in the SIRENE database and connects to the commercial registries (RCS).

It excels at "sirenising" and enriching a file: SIREN, address, website, legal and financial data, and sometimes email. Very solid French data, continuously updated, at an affordable price.

Societeinfo's limits

The main consideration is its scope:

• France only: centered on French registers, it isn't built to target internationally.
• Legal/firmographic focus: its strength is official company data (SIREN, legal, financial); multi-source verified contact enrichment is not its core.
• Limited contact coverage beyond registers: for decision-maker emails and phones at scale, you often need to complement it.

And as with any tool, email must be verified before sending: our study on B2B email quality shows nearly one email in four is invalid.

Listar, the alternative for verified contact data (and international)

Societeinfo is unbeatable on official French company data; Listar focuses on the contact layer: waterfall enrichment (30+ sources) with verification, in France and internationally. The two are complementary.

The waterfall maximizes verified coverage of decision-maker emails and phones (see the B2B data enrichment guide), every address is checked (test it with the verifier), and the scope goes beyond France — pay-as-you-go and GDPR-compliant.

When Societeinfo (or another tool) is still the right fit

Depending on your context:

• Societeinfo: ideal for sirenising and enriching legal and financial data of French companies via API, at a controlled cost.
• Listar: for verified contact coverage (email/phone) via waterfall, in France AND internationally.
• Both: Societeinfo for official company data, Listar for verified contact details — complementary.

How to choose

The question: are you looking for legal and financial data on French companies (Societeinfo excels) or for verified decision-maker contact details at scale, including outside France? For the latter, a verified multi-source waterfall is a better fit — and complements an official-data source very well.
