Case Study: Six & Flow achieves a full mid‑range agency retainer and scalable revenue growth with HubSpot CRM

HubSpot CRM Leads to Full Mid-Range Agency Retainer

Six & Flow is a Manchester‑based growth marketing agency and diamond HubSpot partner that used HubSpot’s free CRM, sales and marketing tools to build early trust with prospects. Their client Inkpact — a London startup that sends handwritten notes at scale — faced fragmented customer data, too many marketing tools, poor visibility into sales and marketing impact, low engagement, and excessive sales admin.

Six & Flow delivered quick wins by implementing HubSpot CRM, running a paid team workshop, then rolling out Marketing Hub Professional and three seats of Sales Hub Professional while aligning sales enablement and integrated nurturing across social, content and email. The phased approach converted Inkpact from free tools to a mid‑range ongoing retainer; agency‑wide, 75% of Six & Flow’s clients start with free tools, 75% of those upgrade to Marketing Hub Professional, and free tools account for 40% of their HubSpot MRR.
