Both Apollo and Lusha can be used legally under GDPR — but the documentation burden differs significantly. Lusha's compliance posture is generally more straightforward for European companies: it provides a clean DPA, SCCs, sub-processors list, and opt-out mechanisms with well-documented data sourcing. Apollo requires more documentation work but is legally usable with SCCs in place. Neither requires EU-based servers — data residency outside the EU is permissible under GDPR when the transfer is properly documented. For Nordic and DACH contact data quality, Lusha has a meaningful advantage.

The GDPR Reality — What EU Servers Actually Mean
The most common misconception about GDPR and B2B prospecting tools is that data must be stored on EU-based servers. It doesn't. GDPR regulates the transfer and processing of personal data — it does not require that data physically stays within EU borders.
What GDPR actually requires for transferring personal data to a US-based processor like Apollo is:
- A signed Data Processing Agreement (DPA) between your company and the tool provider
- Standard Contractual Clauses (SCCs) — the EU's approved legal mechanism for transferring data to countries without adequacy decisions, including the US
- Documentation of the transfer in your Records of Processing Activities (RoPA)
- A sub-processors list — every third party the tool provider shares your data with
- Data subject rights mechanisms — how contacts can request access, deletion, or opt-out
The US is not GDPR-adequate — meaning there's no blanket agreement covering US data transfers the way there is for countries like Japan or South Korea. This doesn't make US-based tools unusable. It means the documentation burden is higher and must be maintained actively.
💡 The practical test: Before your DPO or legal team approves a prospecting tool, they will ask for the DPA, request the SCCs, check whether sub-processors are listed with their locations, and verify how data subject rights requests are handled. If a tool can't provide all of these clearly and quickly, that's a compliance risk — not because the data is stored in the US, but because the documentation to justify the transfer isn't in order.
Apollo's GDPR Posture — Legally Usable, Documentation-Heavy
Apollo is a US company with servers primarily in the US. It is legally usable under GDPR with the right documentation in place — but getting that documentation in order requires more work than some European companies expect.
What Apollo provides
- Data Processing Agreement — available in Apollo's legal documentation, covers the controller-processor relationship
- Standard Contractual Clauses — Apollo incorporates the 2021 EU SCCs into its DPA for European customers, providing the legal basis for US data transfers
- Sub-processors list — published but requires active monitoring as Apollo uses third-party infrastructure including AWS and other US-based services
- Data subject rights — Apollo maintains a contact opt-out mechanism at apollo.io/gdpr-opt-out and processes deletion requests
- Legitimate interests assessment — Apollo publishes documentation on the legal basis for collecting and processing B2B contact data
Where the complexity lies
Apollo's data sourcing is broad — it aggregates contact data from public web sources, user-contributed data, and third-party data providers. This multi-source approach makes the legitimate interests basis more complex to document for European companies, because the original collection method for each contact record varies. For a DPO asking "where did this contact's data originate?", Apollo's answer is less clean than a tool with a more defined data sourcing methodology.
⚠️ Apollo compliance action required: If your company is subject to GDPR and uses Apollo, you must have a signed DPA in place — not just Apollo's standard terms. Request this explicitly from Apollo's legal team. The SCCs must be incorporated. Document Apollo as a data processor in your RoPA with the transfer basis noted. This is your compliance obligation, not Apollo's — they provide the documents, you must implement them.
Lusha's GDPR Posture — Cleaner Documentation for European Teams
Lusha's GDPR compliance posture is generally considered more straightforward for European companies than Apollo's. The data sourcing methodology is more transparent — Lusha's primary sources are LinkedIn profiles and professional directories, making the origin of contact data more traceable than multi-source aggregated databases. This cleaner data provenance makes the legitimate interests basis easier to document and easier for a DPO to review.
What Lusha provides
- Data Processing Agreement — available and straightforward, covers the controller-processor relationship clearly
- Standard Contractual Clauses (SCCs) — available and incorporated for any processing through non-EU infrastructure
- Sub-processors list — published with named sub-processors, their roles, and locations
- Data subject rights — Lusha maintains a dedicated opt-out mechanism and processes GDPR requests. Contacts can opt out at lusha.com/gdpr
- Legitimate interests assessment — Lusha has published documentation on its data sourcing methodology and the legal basis for processing B2B professional contact data
- Data sourcing methodology — Lusha's primary data sources are LinkedIn profiles and professional directories, making the origin of contact data more traceable than Apollo's multi-source aggregated approach
"The key difference in Lusha's GDPR posture is the clarity of data sourcing — LinkedIn-primary data is more traceable than multi-source aggregated databases. For a DPO reviewing the documentation, Lusha's paper trail is cleaner to sign off on."

The Documentation Checklist — What to Request Before Signing Up
Before your company commits to either tool, request and review these five documents. Both Apollo and Lusha will provide them — but you need to actively request them rather than assuming they're automatically in place when you sign up.
Data Quality for Nordic and DACH Markets
GDPR compliance is the first filter for European B2B companies. Data quality is the second — and for companies primarily prospecting into Nordic and DACH markets, the difference between the two tools is meaningful.
Lusha for European contacts
Lusha has stronger European coverage, particularly for direct dial phone numbers in Nordic markets. Finland, Sweden, Norway, and Denmark are markets where professional contact data is less abundant than in Western European economies — fewer contacts appear in large aggregated databases, and direct dials are harder to surface. Lusha's LinkedIn-first sourcing approach works in these markets because LinkedIn penetration is high among B2B professionals across Scandinavia.
For DACH markets — Germany, Austria, Switzerland — Lusha's coverage is solid for mid-to-large companies. German B2B culture means fewer personal mobile numbers are publicly available, but work direct dials and verified email addresses are reachable. Company data enrichment for German manufacturers is generally reliable for companies with 50+ employees.
Apollo for European contacts
Apollo's database is significantly larger overall — over 275 million contacts — but weighted toward North American contacts. European coverage exists but the data density for Nordic markets specifically is lower than Lusha's. For a Finnish manufacturer prospecting into Swedish engineering companies or Norwegian energy companies, Apollo will surface fewer direct dial numbers and more generic email formats than Lusha.
Where Apollo performs better in European contexts is for international accounts — large multinationals with European offices that are well-represented in US-centric databases. If your prospecting includes both European and North American targets, Apollo's breadth becomes an advantage.
💡 The practical test before committing: Before purchasing either tool, run 20-30 of your actual target accounts through each tool's free tier or trial. Check whether the contacts you need — specific job titles at specific company sizes in your target geographies — are present with verified contact information. The results of that test are more useful than any benchmark claim either company makes about their database size.
HubSpot Integration for European Teams
Both Apollo and Lusha integrate natively with HubSpot. The integration approach differs in ways that matter for European teams already using HubSpot as their CRM.
Lusha's HubSpot integration works primarily through the LinkedIn browser extension — you find a contact on LinkedIn, Lusha surfaces their data, and it syncs directly into HubSpot with one click. This is simple, fast, and works reliably. The data that enters HubSpot comes from a single verified source (the LinkedIn profile), which makes the data provenance cleaner for GDPR documentation purposes.
Apollo's HubSpot integration is more feature-rich — two-way sync, sequence management from within HubSpot, account-based workflow triggers, and more granular control over which data fields sync. For teams using HubSpot not just as a CRM but as an outbound sequence platform, Apollo's deeper integration is more powerful. The tradeoff is complexity — it requires more configuration to set up correctly.
For B2B industrial companies using HubSpot primarily as a CRM with occasional prospecting enrichment — adding new contacts, enriching existing records — Lusha's simpler integration is the better fit. For companies running systematic outbound sequences where Apollo and HubSpot need to coordinate closely, Apollo's integration depth earns its complexity.
Who Should Choose Which
- Your primary markets are Nordic or DACH — Lusha's European data coverage is stronger
- Your DPO wants the cleanest possible compliance documentation — Lusha's data sourcing transparency simplifies the paper trail
- Your workflow is LinkedIn-based prospecting into HubSpot — Lusha's browser extension is purpose-built for this
- Your team is small and you need a simple tool that works without extensive configuration
- You prospect into both European and North American markets — Apollo's database breadth is the advantage
- You run systematic outbound sequences and need Apollo's sequence tools alongside the contact database
- You have a dedicated sales ops person who can manage the HubSpot integration setup correctly
- Your compliance team is comfortable with SCCs and US data transfers with proper documentation
For a Nordic or DACH-focused B2B industrial manufacturer, Lusha is the more practical choice — cleaner compliance documentation, stronger European contact coverage, and a simpler HubSpot integration that matches how most industrial sales teams actually work. Apollo is the right choice if your prospecting extends significantly into North American markets or if you need the outbound sequence functionality built into the same tool. The compliance question is not about server location — it's about documentation. Can you get the DPA, SCCs, sub-processors list, and opt-out documentation in order? Both tools can pass that test. Lusha makes it easier, primarily because its data sourcing methodology is more transparent and the paper trail is cleaner.
