SignalHire review

Free trial credits, then published credit-based plans; per-contact costs are competitive, especially where phone numbers are the goal.

Benchmark phones specifically: run your last 50 placed candidates through a trial and count reachable mobiles versus your current tool.

Sourcers who want cheap contact reveals across LinkedIn and GitHub. SignalHire combines a contact-reveal extension (works on LinkedIn, GitHub, and other sites) with a searchable profile database and simple outreach. It competes on price per verified contact.

The phones-included alternative

SignalHire is a credit-based contact finder whose differentiator is phone coverage alongside emails: for recruiting workflows that call candidates — common in staffing, healthcare, trades, and sales recruiting — its mobile-number hit rates benchmark well against pricier options. The product spans a Chrome extension, a searchable candidate database with basic filters, bulk enrichment, and an API.

Credits work simply (one revealed contact = one credit) with published plans, making costs predictable. Accuracy on emails is competitive though generally a notch below ContactOut on personal addresses; the phone coverage is the reason to shortlist it.

Like all pure enrichment tools, it assumes a stack around it: LinkedIn or a database for sourcing, an ATS for tracking, optionally a sequencer for volume. For call-first desks, it's often the best value per reachable candidate.
