Field-tested by my team. Email coverage is the highest I've seen for United Kingdom B2B data. Bought it to scope a United Kingdom territory in the be at one locations segment. Worth the price.
Skeptical at first, given the price. Sample matched live data when I spot-checked random rows. Bought it to map be at one locations density across United Kingdom. Will be the default vendor for us now.
Picked it up for cold outbound. Website URLs were populated for ~80% of rows, far better than the competition. Bought it to underpin a United Kingdom be at one locations campaign. Connect rate could have been higher with cleaner mobile numbers.
