My verdict: the French champion for mobile numbers, essential for cold calling.
The French champion for finding mobile numbers. Kaspr is a Chrome extension that enriches LinkedIn profiles in real-time: email + phone number (mobile included).
Their strength? Mobile coverage in France/Europe is excellent. The interface is simple, enrichment is fast.
What I like less: credits run out fast (1 credit = 1 email OR 1 phone), so it can add up. And for the US market, Lusha is better.
My advice: if you do phone prospecting in Europe, it's almost essential. For emails only, Dropcontact is cheaper.
