Incredible support - making our integration with HubSpot a smooth experience

We worked with Mia for our integration between our legacy ConnectWise platform with a new HubSpot CRM and throughout this project Mia was a voice of calm and reason, bringing expertise and clarity when we needed it. She really helped us to steer through the trickiest of situations and we all felt very secure, knowing she had our backs. Specifically, Mia and the Forbidden team were very knowledgeable about Project Management, CRMs, APIs, integration mapping between two disparate data systems, data hygiene best practice, marketing campaigns, customer journeys and reporting needs for customers like us. I particularly felt that an added bonus was that Mia took the time to understand us as a reseller business and also as people. She brings common sense and a good sense of humour to the process, which defuses the tension and we all enjoyed working with her. I have no hesitation in recommending Forbidden and Mia for CRM, HubSpot onboarding and custom API integrations. We are now working with Forbidden to help us get the most out of our new HubSpot CRM. Many thanks Mia, don't give up the snowboarding!

HubSpot Onboarding with Hannah

Our company has onboarded a CRM for the very first time, and choosing HubSpot has been a fantastic decision. The entire team, from Viktor to Hannah, have been incredibly knowledgeable, honest, and realistic throughout the process. The onboarding experience has been great, with a generous amount of time dedicated to making sure we felt supported and confident. Response times have also been very good, which has made the whole experience smooth and stress‑free.

Excellent implementation of HubSpot

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

CRM Implementation

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.

Great Partner for Our Salesforce → HubSpot Migration

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.

Great support

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.

We’ve had a fantastic experience working with Forbidden

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.

Discovery and Strategic Blueprinting for Complex Operations Set Up

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.

Complex HubSpot instance audit + improvement recommendations

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.

HubSpot Onboarding

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.
