  • Proactively identify, prioritize, and address technical debt to ensure long-term code quality and maintainability

Our take

Although LinkedIn is a potent tool for business-to-business sales, it can be difficult to locate the contact details of the right people to get in touch with. Kaspr is helping sales teams convert prospects into leads with a chrome extension and dashboard that displays and organises the business phone numbers and email addresses of LinkedIn contacts.

While what Kaspr is offering is quite a simple concept, its strength is in the reach of its database, consisting of over 160 million email address and 30 million phone numbers. Its ease of integration with existing customer relationship management systems is also key to its success - instead of replacing existing technology it adds another layer of functionality to most systems. So far this solution has secured it a client base of 1,500 corporate customers and over 50,000 users.

Kaspr was recently aquired by Cognism, a UK-based sales intelligence company, allowing it to coordinate with its parent company's marketing activities. It will now be focused on expanding its presence in the European market, growing its contact database and further developing its product, taking on new engineering talent to make this possible.
