Seamless Onboarding Experience

Working with Six & Flow to onboard and integrate HubSpot has been a genuinely positive experience for our team. Their video tutorials were incredibly useful and insightful, making even the more complex elements of the platform easy to follow. They were efficient with every call, always using the time to its fullest and keeping sessions focused and productive. The team’s dedication really stood out, each person we worked with helped us understand not just the ‘how’, but the ‘why’, giving us confidence in new ways of working. Most importantly, they provided clear, practical solutions that were easy to understand and simple to replicate across our wider processes. Their support has set us up for long-term success, and we wouldn’t hesitate to recommend them.

6th and Flow Agency -

Working with 6th and Flow has been a truly rewarding experience. From the outset, their organisation and approach to strategic data mapping allowed us to maximise the value of the services provided. Their ability to align tools and processes with our specific business needs meant that every step of the project was both purposeful and impactful. One of the standout aspects was the full visibility they provided throughout the engagement. Leveraging the right tools, we had a clear view of the roadmap and real-time status updates, which kept everything on track and transparent. Each team we worked with brought strong expertise in their field and consistently delivered tailored solutions that directly addressed our challenges. Big shout out to Duncan, Emmanuel, and Dean, who each brought valuable support and insight throughout the project. Their contributions helped ensure a smooth and effective implementation from start to finish. A special thanks to Nisha, who led the project with professionalism and agility. She was highly responsive to our queries, adapted quickly to evolving needs, and played a crucial role in the successful onboarding of our Customer Success team. We would highly recommend 6th and Flow to any organisation looking for a best-in-class HubSpot setup and a strategic partner to drive lead engagement and conversion. Their depth of knowledge, structured approach, and dedication to client success make them a standout agency in this space. Clarissa M

Fantastic!

I have really enjoyed working with the team at Six and Flow. They have been a very open and knowledgeable partner for us. As we embarked on our HubSpot journey, they have provided impartial advice along with sharing their knowledge and best practice of how to extract maximum value from the platform. As we continue to work with them throughout the remainder of our project - I'm excited to see how our collaboration can develop.

Nrupal is awesome!

HubSpot can feel a bit overwhelming but Nrupal did an amazing job at making sure we were taken care of. He was patient and offered additional support multiple times. He was also super kind which is a bonus!

Brilliant support

The team have been incredibly supportive and helpful from the start of the CRM implementation and throughout the ongoing support period. With no previous HubSpot experience, the team have always been there to assist with any difficulties we've had and to build on our knowledge so we can make the best use of the system and associated tools moving forward. They have been an absolute pleasure to work with.

Six & Flow have been a dream to work with

From the point of enquiry and scoping out the services we needed, through to strategy sessions, delivery, and post-project review, the Six & Flow team have been fantastic. Courteous, strategically effective, and technically knowledgeable. We have now successfully migrated from Salesforce to HubSpot, bringing 15 years of data with us. It's all cleaner, more useful, and the setup of HubSpot that Six and Flow led has already accelerated our sales, marketing, and BD processes significantly. Huge thanks to Andy, Joseph, Mel, Duncan, Sam, and Tom! We'll be back for more Sales Operations support in the (hopefully near) future.

Great support migrating to HubSpot

Six and Flow were invaluable helping us migrate to HubSpot CRM. The project came with many challenges as we attempted to connect old systems with new, but the team at Six and Flow found solutions each time. Thanks to their knowledge and support, we now have a HubSpot CRM platform that is effectively integrated with our key systems.
