I've been using SignalHire for six months -- it really saves a ton of time. You can find the necessary contacts in just a couple of clicks through the browser extension. The database is up-to-date, although occasionally you'll encounter outdated information. The price is reasonable and pays off quickly. Customer support is responsive. Definitely recommend for sales and recruiting.

SignalHire changed my outreach game completely. After struggling to find decision-makers' contact info, I tried it and immediately found verified emails for 3 VPs I'd been trying to reach for weeks. Now I spend less time researching and more time actually selling. Worth every penny for my B2B sales process.

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

SignalHire - find email or phone number requires a lot of sensitive permissions. Exercise caution before installing.
