Honest take

Where Apollo shines.

Apollo is a well-established platform with a massive contact database. Here is where it excels.

275M+ contact database

One of the largest B2B contact databases available. Search by company, role, industry, seniority, and dozens of other filters — all without external enrichment calls.

Built-in email sequencing & dialer

Create multi-step email sequences, A/B test subject lines, and make calls directly from the platform. No need for a separate outreach tool.

Chrome extension

Prospect directly on LinkedIn and company websites. View contact details, add to sequences, and log activities without leaving your browser.

Generous free tier

600 email credits per month on the free plan. Enough for solo SDRs to start prospecting immediately without a budget commitment.

All-in-one for outbound

Database, enrichment, sequencing, and dialer in a single tool. For teams that want everything in one place, Apollo removes the need to stitch together multiple tools.

Large community & adoption

Widely adopted by sales teams worldwide, with extensive documentation, university courses, and a large user community sharing best practices.

Different approach

Where ListPlus is different.

ListPlus takes a pipeline-first, API-native approach to contact data operations.

AI Agent API: read + write

Any AI — Claude, GPT, custom agents — can autonomously operate your entire pipeline via REST API or MCP. 20+ actions, from enrichment to filtering to CRM sync. Apollo does not offer an agent API.

Waterfall enrichment (15+ providers)

Instead of relying on a single database, ListPlus chains 15+ premium providers in a waterfall. If provider A misses, provider B catches it. Higher coverage, pay-when-found pricing.

Built-in research tools

Google Search, Reddit, Hacker News, X/Twitter, LinkedIn lookup, and web scraping are built into the API. Your AI can research companies and contacts autonomously — no separate subscriptions needed.

Self-describing API

One URL. Your AI reads the schema, understands every action, and starts operating. No documentation lookup, no SDK required.

EU-hosted, GDPR compliant

All data processed and stored in Frankfurt, Germany. SOC 2 Type 2 infrastructure. Apollo is US-hosted only — a consideration for EU teams handling personal data.

42+ smart filters & quality scoring

Content-aware filters (role detection, email intelligence, fuzzy match) and 107+ automated data quality checks with a 0–10 score. Catch duplicates, formatting issues, and invalid data before it reaches your CRM.

Live bidirectional CRM sync

Changes in your CRM flow back to ListPlus and vice versa. Apollo offers one-way push to CRM — ListPlus keeps both sides in sync automatically.

Who should choose Apollo.

  • SDRs and sales teams that want a contact database with built-in email sequencing and dialer in one tool.
  • Teams doing high-volume LinkedIn prospecting with a Chrome extension workflow.
  • Solo reps or small teams starting with a generous free tier and scaling to $49/user/mo.

  • Teams that want waterfall enrichment across 15+ providers instead of relying on a single database.
  • DACH and EU-based teams that require EU data residency and GDPR compliance.
  • Organizations that already use a dedicated outreach tool (Lemlist, Instantly, Smartlead) and need a better enrichment layer.
  • AI agent builders who need a self-describing API with built-in research capabilities.
FAQ

Frequently asked questions.

Is ListPlus a replacement for Apollo?
They serve different primary purposes. Apollo is a contact database with built-in outreach — great for teams that want prospecting, sequencing, and calling in one tool. ListPlus is an enrichment pipeline with an AI Agent API — built for teams that want AI-driven data operations and waterfall enrichment. Some teams replace Apollo with ListPlus + a dedicated outreach tool. Others use both side by side.
Can I use both Apollo and ListPlus together?
Yes. A common setup is using Apollo for its contact database and sequencing while using ListPlus for waterfall enrichment, data quality scoring, and AI-powered pipeline operations. ListPlus can enrich and score data before you push it to Apollo or your CRM.
Does ListPlus have a contact database?
No. ListPlus does not maintain its own contact database. Instead, it aggregates 15+ premium enrichment providers in a waterfall: if the first provider misses, the next one picks it up. This approach often achieves higher coverage than a single database, and you only pay when data is actually found.
How does pricing compare?
Apollo offers a free tier (600 email credits/mo), Basic at $49/user/mo, and Professional at $99/user/mo. ListPlus starts free (250 records, 25 credits), Pro at €39/mo with CRM sync, and Premium at €79/mo with 100,000 records and AI Agent API. Apollo charges per user; ListPlus charges per workspace. Both use credit-based enrichment on top of the subscription.
Which tool is better for EU teams?
ListPlus is EU-hosted (Frankfurt) and processes all data within the EU. This matters for GDPR compliance, especially when handling personal contact data. Apollo is US-hosted. For DACH and EU teams with strict data residency requirements, ListPlus is the safer choice.
Does ListPlus have email sequencing?
No. ListPlus focuses on enrichment, data quality, and AI pipeline operations. For outreach, it integrates with dedicated tools like Lemlist, Instantly, and Smartlead. Apollo includes built-in sequencing and a dialer — if you need everything in one tool, that is Apollo’s strength.
