Linq

Linq (Linq App, Inc.) is a US provider for digital business cards, NFC cards and lead capture, founded in 2019 in Birmingham, Alabama. For years the product was positioned as a team and enterprise solution for sales organizations and achieves very good ratings on independent platforms (G2 around 4.8/5 from about 553 reviews, 88 percent of which are five stars). In the overall comparison, Linq achieves a score of 59 out of 100 points. This places the provider in the midfield: feature scope (70) and team/admin management (66) are solid, and user satisfaction (84) is the strongest single value. The rating is held back by the categories decisive for the German B2B market: GDPR (50), enterprise integration (50) and support & language (50).

Decisive for the assessment is a strategic caveat: in 2025/2026 Linq shifted heavily away from digital business cards toward AI messaging infrastructure and, in February 2026, raised a Series A round of USD 20 million for this repositioning. According to several market sources, the original NFC/business card product is considered largely discontinued or to have an uncertain future. For a long-term B2B rollout, this risk must be weighed carefully.

From a data protection perspective, Linq achieves 50 out of 100 points. Data is held exclusively in the USA; EU or Germany hosting is not known, and the specific cloud provider and region are not publicly stated.

For the processing of personal data of German employees and contacts, this means a GDPR third-country transfer that is only safeguarded via EU standard contractual clauses (SCC). Positive factors are a data processing agreement (DPA), which is publicly available and obtainable on request by email, as well as a SOC 2 Type II certification (audit by Sensiba San Filippo) and a public Trust Center at security-report.linqapp.com.

An ISO 27001 certification is not documented. In sum, Linq is formally equipped in contractual GDPR terms, but falls short of the criterion central to German and European companies: an EU/DE server location.

Providers with consistent Germany hosting including a data processing agreement (DPA) under Art. 28 GDPR (such as oneVcard) have the advantage here, because they avoid the third-country transfer from the outset.

For enterprise suitability, Linq achieves 50 points, and for team and admin management 66. Available features include central admin/team management, custom branding for a consistent corporate presence, a public API as well as direct CRM integrations with Salesforce and HubSpot.

This makes it possible to map sales workflows and lead handover in principle. The classic enterprise identity functions are, however, a gap: single sign-on (SAML/OIDC), automated user provisioning via SCIM as well as MDM connectivity (Microsoft Intune, Jamf) are not publicly documented or are unclear.

Automated bulk provisioning and centralized email signature management are also not confirmed. For IT-driven rollouts across larger workforces, where automated on- and offboarding via SSO/SCIM is expected, this is a noticeable disadvantage.

The enterprise rating is further aggravated by the strategic risk of the product repositioning, which burdens the predictability of a multi-year enterprise deployment.
