02Pricing compared
Apollo Basic costs $49 per seat per month with annual billing, paid upfront, or $65 per seat on monthly billing, according to the pricing page. Its free plan includes 75 credits per seat monthly, two email sequences and a 25-record selection limit. Professional starts at $79 per seat monthly with annual billing; Organization starts at $119 and requires at least three seats.
SignalHire’s lower-tier plans start at $57 per month with annual billing, or $69 monthly. That price covers unlimited users, but credits and data type depend on the plan: the lower Emails tier lists 1,000 monthly credits, while lower Phones and Emails & Phones tiers list 435. Both products have free plans. SignalHire’s free credits vary by feature; neither free offer should be treated as equivalent to a paid prospecting allowance.
03Features and depth
Apollo combines B2B data with prospecting, outreach, dialing and AI agents. Its homepage lists 240M+ contacts and 30M+ accounts. Teams can manage sequences and dialing in one workspace, use agents to research accounts or write follow-ups, enrich records through waterfall enrichment, and access Apollo from tools including Gmail, a browser, ChatGPT and Claude. Buying signals include intent, job changes and website visits.
SignalHire is more focused on finding and enriching contacts. Its database lists 900M+ profiles and 30M+ companies, with filters for name, title, company and location. It offers verified email and phone lookup, bulk enrichment for up to 1,000 people or companies, a Chrome or Firefox extension, email sequences, APIs, CRM and ATS sync, and CSV export. The database totals are not directly comparable: Apollo reports contacts and accounts, while SignalHire reports profiles and companies. Check the relevant credit allowance before comparing record volume. SignalHire’s higher-tier credit limits are not published.
04Ease of use and learning curve
The published product information does not publish setup times or learning-curve details, so we would not call either one easier based on it alone. Apollo puts prospecting, outreach, dialing and AI agents in one system, which may suit teams that want those workflows together. Its plans are per seat and add limits such as selection caps and workflow allowances.
SignalHire has a narrower contact-discovery focus, but buyers must choose between email, phone and combined plans, each with different credit allowances. It supports browser lookup, email sequences, APIs and CRM or ATS sync. Before switching, map your current users, required data types and monthly lookup volume to the plan limits—not just the headline price.

Which has more contact data?
SignalHire lists 900M+ profiles and 30M+ companies; Apollo’s homepage lists 240M+ contacts and 30M+ accounts.
