The product

Nymblr gave salespeople and marketers verified B2B leads and audiences for cold outbound and targeted ads. In the site's own words, the platform and APIs made it easy to "access B2B leads and custom audiences," enrich existing contact data, and validate work and personal emails in real time.
- Prospect Finder for searching contacts by title, seniority, department and company.
- Audience Builder for custom lists for cold email and ad platforms.
- Enrich via the platform or API.
- White Label for agencies and service providers.
- Real-time email validation, with no charge for invalid or catch-all emails, and unlimited users on every plan.
After the acquisition

Inunity renamed the product Nimbler. By December 2023 the site carried the new name, with the tagline "(Previously Nymblr)" under the same headline. Inunity later absorbed Nimbler into Textedly, its SMS marketing platform.
