SignalHire.com is a B2B contact-finding and lead-data platform that helps recruiters, sales teams, and marketers find professional email addresses, phone numbers, company data, and social profiles.
What is SignalHire.com used for?
SignalHire.com mainly turns public professional information into searchable contact and company records.
SignalHire says its platform is designed for recruiters, marketers, HR specialists, sales teams, and other professionals who need to contact people for business purposes.
The service lets users search by details such as a person's name, job title, company, or location.
Users can then reveal available work emails, personal emails, telephone numbers, and social profiles.
SignalHire also supports bulk searches, contact enrichment, lead lists, data exports, API access, and connections with recruiting or sales software.
How large is the SignalHire database?
SignalHire.com currently advertises access to more than 900 million professional profiles and over 30 million companies on its main website and pricing pages.
Another SignalHire database page still states more than 850 million profiles, so the company's own pages do not use one consistent database figure.
The most useful takeaway is that SignalHire operates a very large international B2B database rather than a small email lookup directory.
SignalHire says its database receives continuing updates from web sources and that full contact information is checked when users request it.
The company also claims email coverage of up to 90 percent and phone coverage of up to 80 percent, although those figures are SignalHire's own marketing claims rather than independent measurements.
How does the SignalHire browser extension work?
The SignalHire extension lets a user look for contact details while viewing professional profiles and other websites.
SignalHire says its extension supports sites including LinkedIn, Facebook, X, GitHub, and Meetup.
A user opens a profile, activates the extension, and requests the person's available contact information.
One credit is normally charged when SignalHire successfully returns at least one email address or phone number.
SignalHire's own extension page reports more than 350,000 users.
Google's Chrome Web Store listed version 5.12.0 as updated on September 20, 2026, with a 4.6-out-of-5 rating based on 568 ratings when checked in September 2026.
How much does SignalHire.com cost?
SignalHire.com has a free plan that does not require a credit card.
The pricing page says a standard free account receives five contact credits, while installing the extension can increase the allowance to 10 free credits each month.
As of September 2026, SignalHire lists an email-only plan at $69 per month for 1,000 credits.
Its annual email plan is displayed at $57 per month and includes 12,000 credits across the billing period.
Phone-only and combined email-and-phone packages are also shown from $69 monthly, while larger Scale packages require contacting the sales team.
Paid plans can include unlimited team users, CSV enrichment, exports, browser-extension access, API access, and ATS or CRM integrations.
Pricing can change, so checking the live SignalHire.com pricing page before subscribing matters.
Can SignalHire connect with recruiting and sales tools?
SignalHire says it provides direct integrations with more than 25 tools.
Its listed integrations include recruiting systems such as Recruitee, CATS, PCRecruiter, and Avionté, along with sales tools such as Reply.
The platform also provides REST API features for teams that want contact discovery or enrichment inside their own applications.
SignalHire says its Person API can retrieve profiles using information such as a social-profile URL, email address, or phone number.
Bulk enrichment can process as many as 1,000 profiles at once, according to SignalHire.
Where does SignalHire get personal information?
SignalHire's Privacy Policy says its Prospects Database is built from publicly available web data.
Its Terms of Service additionally describes professional information as coming from publicly available web data, third-party sources, or users.
This distinction matters because appearing on SignalHire does not necessarily mean that a person created a SignalHire account.
The company's Privacy Policy was last updated on September 15, 2026, and identifies the operator as SignalHire Sp. z o.o.
SignalHire lists its company address in Warsaw, Poland.
Can you remove your information from SignalHire.com?
Yes, SignalHire provides a profile opt-out process for people who want their professional profile removed.
Its opt-out form asks for a business email address and the URL of the SignalHire profile being removed.
People can also send a removal request to SignalHire's support email.
SignalHire's Privacy FAQ says valid privacy requests are typically processed within 30 to 45 days depending on the applicable jurisdiction.
The company says it supports GDPR rights to access, correct, or delete personal information and provides CCPA-related access, deletion, and opt-out options.
SignalHire may retain an email address on an opt-out list so that removed information is less likely to be collected again.
What should users know before paying for SignalHire?
SignalHire has substantial search, enrichment, extension, API, and integration features, but contact-data quality should be tested with the free credits before buying a large package.
Independent customer feedback is mixed.
Trustpilot displayed 61 SignalHire reviews when checked in September 2026, with 59 percent carrying one star.
More importantly, Trustpilot said SignalHire's overall rating was unavailable because of a breach of its guidelines and stated that it had removed a number of fake reviews.
That warning makes the raw review distribution less useful as a simple measure of product quality.
A practical evaluation should therefore test SignalHire.com against a small known sample of contacts, measure how many emails and phone numbers are correct, calculate the cost per usable contact, and review its privacy requirements before using the data for large-scale outreach.
