What is Hubspot? Steven from iO explains

HubSpot is one of the most famous marketing automation tools in the world. With HubSpot you can generate, manage and maintain qualitative, potential customers. Our HubSpot experts know what they're talking about.

Why you should use HubSpot

HubSpot is a CRM and automation platform that brings together in one place everything that growing companies need to deliver a great customer experience, from the first contact to the last.

HubSpot not only allows you to fully set up marketing automation and lead generation campaigns, but also gives you extensive CRM and sales functionalities, customer surveys, and all the necessary tools to create reports across the entire customer journey.

By centralising all data and activities from different departments within your company into HubSpot, your teams can establish deeper relationships with customers and prospects throughout the entire customer journey. And that automatically results in more and more satisfied customers.
