👉 HubSpot CRM Solutions for Marketing Agencies & Consultancies

Influencer are the trusted ally of 95% top-tier global brands featured in Ad Age and the largest media agencies. They maintain strategic alliances with the world's most influential social media platforms.

The marketing and sales teams had been using HubSpot for a few years. As the business has grown, so the data started to get a bit messy. There was also a sense that initial setup could be improved to ensure the business was getting full value from their investment. 

Over the course of 4 months, we helped to overhaul Influencer's CRM completely, ensuring best practice implementation in all areas. We focused particularly on improving and aligning sales operations across regions, enhancing marketing automation, lead and revenue attribution, campaign management, and reporting. After the optimisation project, we continued to provide ongoing ad hoc support as required.

Clarity Global is an international marketing and communications agency that helps ambitious brands grow through strategic communications, performance marketing, and digital expertise. Following its acquisition of 93Digital and 93x, Clarity needed to unify data from multiple legacy systems and create a single source of truth for marketing and sales. The team also wanted to strengthen campaign attribution, automate lead management, and implement cross-domain tracking across their network of websites.

Growth London completed a CRM migration and HubSpot onboarding, consolidating data from CopperCRM and legacy HubSpot. We implemented Marketing and Sales Hub Professional, rebuilt pipelines, set up GDPR forms, and integrated website tracking. With dashboards, lead scoring, and attribution, Clarity now has a cohesive CRM foundation supporting collaboration, reporting, and growth.

M&C Saatchi Performance is a global and multi-award winning digital media agency providing innovative media strategies to some of the biggest brands in the world. Its team of specialists manage campaign effectiveness with a relentless focus on optimising channels, content, format and placements.

We provided complete partner-led implementation, onboarding and rollout of HubSpot Marketing Hub Enterprise, Sales and Ops Hub across all of the business units globally. The project included migration of legacy data from Pipedrive, website integration, comprehensive reporting (global and regional) and training across all hubs, followed by an ongoing support and optimisation retainer to ensure adoption.

NEST Commerce is a specialist agency delivering full-funnel creative and performance campaigns for high-growth eCommerce brands including Hims, Reiss, and Trinny London. While they had used HubSpot for several years, the platform was underutilised—particularly in client services and reporting—and lacked the structure needed for scaling effectively.

Growth London supported NEST with a CRM optimisation project focused on data integrity, lifecycle accuracy, and full-funnel visibility across teams. We also built reporting aligned to their client service needs and delivered custom landing pages for webinars and events. The result was a HubSpot setup that better reflects NEST’s agency model and provides a solid platform for growth.

Public First is a strategy and research consultancy that helps organisations understand public opinion and communicate effectively across policy, business, and society. With multiple teams managing client relationships independently, the company lacked a shared view of contacts, opportunities, and revenue forecasting. Data lived in spreadsheets, and the leadership team needed a central system to track client engagement, monitor pipeline health, and improve collaboration across departments.

Growth London implemented HubSpot CRM to provide a unified platform for managing relationships, projects, and revenue pipelines. We configured Marketing and Sales Hub, designed custom pipelines for different practice areas, and set up dashboards for visibility across teams. The project included data migration, custom configuration, user onboarding, and training on data hygiene, reporting, and lifecycle management. Public First now has a single CRM source of truth that enables better coordination, forecasting, and growth planning.

MediaSense required a CRM to provide improved customer lifecycle visibility whilst removing the data silos between the marketing and sales functions. After an extensive consultation process Growth London were selected to provide full set up and onboarding for marketing and sales hubs. This included migration from the legacy CRM and marketing tools and building out a custom implementation suited to MediaSense' unique target audience and business model.

After a successful rollout of HubSpot, which was completed on time and on budget, we now continue to provide ad hoc support.
