B2B contact databases are still one of the fastest ways to build pipeline. But the quality gap between providers is massive, and if you pick the wrong one, you do not just waste money, you waste reps.
1. Proxycurl

Proxycurl was known for its APIs for data-driven applications, enriching person and company data with a wide range of fresh datapoints returned on demand. It also offered a large database with over 401M people and company profiles.
Update: Proxycurl API has been sunset. I am the founder behind Proxycurl, and the work has since moved to NinjaPear, where we are building a broader B2B intelligence platform around company, people, customer, competitor, and monitoring data. I am leaving this section here for historical context because the product was genuinely important in this category.
Highlights
- Offers various datapoints on individuals and companies, including phone numbers, personal and work emails, funding data, industry data, social media profiles, and past and current employment details, up to 44 datapoints
- Pros: Very fresh and updated data. Offers free trials. 95+ deliverability. Does not require privacy permissions from you. Compliant with GDPR and CCPA
- Cons: Public profiles only
- Pricing: Pay as you go starting from US $0.01/credit. 3 credits per profile. Trial API key on initial sign up with 10 free credits. Enterprise volume pricing available
TLDR Verdict
Go for it if you value fresh and accurate profile data to enrich your databases. If you are evaluating options today, look at NinjaPear instead of trying to buy into a product that has already been sunset.
