ContactLevel vs Nalloo

ContactLevel is a contact-level advertising platform for targeting specific people within key accounts. It syncs contact audiences to LinkedIn, Meta, Google, Reddit, and X (Twitter). Users can provide B2B email lists by CSV, import contacts from a CRM, or use ContactLevel’s built-in search. Reveal identifies website visitors by name, title, and company, can send Slack and email alerts, and can push data to a CRM. Named CRM integrations include HubSpot, Salesforce, and Attio. ContactLevel says its identity graph maps business data to personal identities and delivers 70–99% match rates. The free Analytics plan connects LinkedIn Ads and reports company engagement, ICP spend, revenue attribution, CRM integrations, and CSV exports with digests. Reveal starts at $299 a month. Grow starts at $1,000 a month for 10,000 net new contacts; listed options also include 30,000 contacts for $2,500 a month and 50,000 for $3,500 a month. Enterprise & Agency pricing is custom.

Nalloo identifies companies behind anonymous B2B website traffic, including company name, domain, and on-site intent. Company details can include industry, size, headquarters, founding year, and technology hints from public sources. It connects to HubSpot, Salesforce, and Pipedrive through one-click OAuth integrations; an optional IMAP inbox scanner can also surface and enrich companies that have emailed you. Branded nll.me short links provide company-level click attribution. Nalloo says it identifies companies rather than people, stores no personal profiles or PII for visitor identification, and hashes visitor IPs inside the EU. Its approximately 13 KB JavaScript tracker loads asynchronously, with installation instructions for WordPress, Shopify, Webflow, Google Tag Manager, and plain HTML. The free plan is billed at €0 forever and includes 50 monthly identifications. Pay as you go costs €0.20 per token with no monthly fee. Starter is €75/mo and Scale is €500/mo; Enterprise pricing is custom. New-company identification pauses at the allowance limit unless pay-as-you-go is enabled.
