SignalHire's pricing is best suited for mid-market recruiting, staffing, and sales teams in the 51-1000 employee range, which represent the dominant reviewer segment on G2. G2 reviewers in staffing, HR, computer software, and logistics report the strongest ROI, particularly when using SignalHire for high-volume LinkedIn prospecting and outbound recruiting. The Base tier at $39.00/month suits small businesses and freelancers with moderate outreach needs, as confirmed by G2 users in consumer services and IT. The $2,500.00/year unlimited tier targets mid-market and enterprise teams running continuous prospecting at scale. G2 reviewers note cost-per-user economics improve substantially with larger teams, making SignalHire less competitive for solo users or micro-teams.
