We have just completed implementation of HubSpot with the assistance and guidance of Chrissy Hamilton of Forbidden. We have achieved a huge amount and a big thank you to Chrissy for her understanding and professionalism throughout. We are delighted and have enjoyed working with Chrissy and learning how much HubSpot can do for us. Thank you. Christopher
Working with Forbidden as our HubSpot implementation partner has been a genuinely excellent experience, and I don't say that lightly. As tech implementation specialists ourselves (albeit in a different field), we came into the project with a strong understanding of the principles behind successful system implementations, but with no prior hands-on experience of HubSpot. Forbidden struck exactly the right balance for us — bringing deep platform expertise while collaborating with us as true partners throughout the process. They took the time to understand how we like to work and were flexible around our timelines, which made a big difference. Rather than imposing a rigid methodology, they provided a clear recommended project structure and best-practice guidance, while remaining adaptable enough to fit our business needs and preferences. This approach allowed us to combine our own implementation experience with their HubSpot expertise, creating a collaborative and constructive working relationship that delivered real value. The team were knowledgeable, pragmatic, and easy to work with at every stage. I would highly recommend Forbidden to any organisation looking for a HubSpot implementation partner who combines strong technical expertise with a genuinely collaborative approach.
We worked with Forbidden on our CRM migration from Salesforce to HubSpot and had a really positive experience. The team kept the project well organized, delivered everything on time, and communicated clearly throughout. CRM migrations can be complex, but they made the process feel smooth and manageable from start to finish. Shoutout to Alan, who was fantastic to work with — proactive, communicative, and instrumental in keeping the project on track. We’re now up and running in HubSpot with a much clearer and more efficient CRM setup. I’d definitely recommend Forbidden to anyone looking for support with a HubSpot implementation or CRM migration.
Jack from Forbidden has taken us through the onboarding process for our CRM, sales and marketing needs with efficiency and a great appreciation for the needs of our business. Our project required the transition from a series of other platforms to HubSpot and integrating a sometimes disparate team and functions, dealing with some internal delays on our end with patience and preparation. It's been quicker than I anticipated and Jack has always been on hand not only getting to really understand our needs and setup in what is often an analogue sales process, but responding to immediate and specific needs and questions with helpful ideas and solutions.
I genuinely can’t speak highly enough of the Forbidden team. From day one, they showed a strong understanding of both the technical requirements and the wider business context of what we’re building. Jack Harris in particular was outstanding throughout. His attention to detail, responsiveness, and proactive approach made a huge difference — consistently going beyond what was asked and ensuring everything was delivered to a very high standard. Communication was clear, timelines were met, and the experience felt like a true partnership rather than a typical client–vendor relationship. I’d highly recommend Forbidden, and especially Jack, to anyone looking for a skilled and dependable development partner.
We have just completed the Discovery stage of our HubSpot implementation with Forbidden, and the experience has been excellent. Leading the process, Chrissy and David were instrumental in aligning our various internal teams across Marketing, Sales, Service, Customer Success and Finance into a single, cohesive vision. The process was incredibly thorough and well-managed. Chrissy and David took a truly collaborative approach, using precise questioning to extract the necessary technical requirements from our existing fragmented stack. They didn't just listen; they challenged us to think about long-term scalability. The final Blueprint document provides a clear and detailed roadmap for our transition from Pipedrive, Zendesk, and Mailchimp into a unified HubSpot ecosystem. It perfectly balances our complex integration needs for Maxio, Monday.com, and Azure DevOps with a native first approach that ensures data integrity. We are looking forward to kicking off 2026 and progressing into the build phase with a highly capable and professional partner.
We worked with the Forbidden team on a deep audit of our existing HubSpot setup, and the experience was genuinely excellent. Ours is a fairly complex use case, with multiple teams relying on HubSpot in different ways, so we needed more than surface-level recommendations — we needed someone who could properly get under the skin of how the business operates. The process was thorough and well structured from the outset. Forbidden led an in-depth discovery phase across finance, sales, marketing and exec leadership, ensuring every perspective was understood before moving into the audit itself. The result was a set of clear, practical recommendations focused on streamlining our CRM, improving usability, and reducing unnecessary complexity — without breaking what already works. What stood out most was the quality of thinking and the way the team challenged assumptions constructively. They were rigorous where needed, pragmatic about constraints, and always grounded in how HubSpot should support real workflows rather than theoretical best practice. If you’re operating a mature or complex HubSpot instance and need clarity on how to simplify, scale, or future-proof it, Forbidden are a brilliant partner. Thoughtful, organised, and genuinely invested in helping you make better decisions.
Scott was a pleasure to work with throughout our HubSpot onboarding. He was articulate, concise, and made the entire process easy to understand. He delivered everything on time, and each meeting was well planned, with a clear agenda and a thoughtful approach tailored to our needs. The training provided at the end of the project was also well structured and highly effective.
Scott was great throughout our HubSpot implementation. He took the time to fully understand our needs and worked through the implementation with us step by step, keeping us up to date, remaining cheerful and provided the training and support required. Would definitely recommend.
Jack was extremely patient with us (I'd imagine there were a few head in hands moments for him!), very knowledgeable and overall super helpful when carrying out our HubSpot Onboarding. He helped us over the course of a few months talking in great depth around the features of HubSpot and offered so much valuable guidance to get us to a point where we can utilise the features independently for the most part. A huge thing I thought was useful where the process is backed by great management tools that keep you on track and you're never unsure as to what to do next. Huge thanks to Jack & Forbidden.
