HubSpot

It's been a great experience to partner with Nexa Cognition on implementing smarter ways of working with HubSpot. The sessions were really useful, with lots of bonus insights on sales and marketing approaches. Following it, the support on a day-to-day basis has been fantastic, so many learnings and tips on how to make the most of the platform. They're real experts and the positive attitude makes the whole difference.

We had a one-on-one training session with Nexa Cognition focused on improving our data quality and record management. Monica was fantastic from start to finish and the session was tailored to our needs. She is extremely knowledgeable and experienced and gave us best practices and industry tips. The follow-up support was also invaluable, helping us to problem solve queries in the system.

Nexa Cognition has been really good at understanding our needs and the specificities of our audience and sales process. They helped in the whole sales and marketing journey from the website design, the CRM implementation, the digi- tal Marketing to the lead nurturing. They made the HubSpot user experience easier and fluid.

Kadiri, L

Nexa Cognition has supported the growth of Pure Minds Academy since 2016, which is when they convinced us that the commercial foundations of our business should be built using HubSpot. Not only has every iteration of our website been on this platform but today we use the full marketing, sales and customer service features as well. The team at Nexa Cognition has also trained us so that day to day website management (including the creation of new pages), landing pages, email marketing, campaigns and even social media posts and publishing are managed by our small team. All in all, from branding to genuine business growth, the team and I can't recommend Nexa Cognition highly enough

Their proficiency in HubSpot CRM set-up and migration is unparalleled, and their unwavering commitment to excellence has made them stand out as one of the best agencies I've ever collaborated with. From the very beginning, Nexa Cognition displayed an unmatched level of attentiveness and dedication. Despite the complexity of the task, Nexa Cognition tackled it with finesse and professionalism, assuring us that we were in capable hands.

Nexa Cognition completely rebuilt our approach to sales through utilising HubSpot and its features limited to our currently license. They understood clearly our pain points and requirements and delivered a solution which will help us grow as an organisation now for the foreseeable. Shout out to Gary, Sam, Aman & Heena for their great professionalism and support!
