Reviews across the web
Coresignal's public review base is sparse — roughly a dozen reviews each on G2 (4.5) and Datarade (4.8) — which fits a vendor selling bulk datasets to data teams rather than seats to salespeople. Sentiment is positive about the scale and freshness of the raw data, while the recurring criticisms are the absence of contact data (no emails or phones), a clunky self-serve experience (one Reddit tester scored it 6/10), and a high upfront commitment before quality can be assessed.
Full roundup →Prospeo is a newer email finder with a strong G2 profile (4.6 across ~437 reviews) and a reputation for accuracy and low bounce rates, especially on LinkedIn-based workflows. The main friction points in negative reviews are credit consumption on bulk jobs that return few matches, and slow support on billing issues. Note that Prospeo publishes many comparison pages about competitors, so third-party coverage of the space often traces back to its own content.
