Six & Flow review: services, focus, and alternatives

Six & Flow is a HubSpot consultancy and revenue-focused growth agency that helps companies run go-to-market on HubSpot. Its HubSpot line covers implementation, AI and CRM enablement, and training. Its RevOps line covers RevOps consulting, RevOps foundations, demand generation and sales enablement. A data and tech line covers data consulting and integrations. It also sells AI consulting through what it calls the FLAIR Framework, and its footer links to FlowConnect. It describes itself as a HubSpot Elite Partner with more than ten years of experience, and it is ISO 27001 certified.

Six & Flow works with B2B organisations that run, or plan to run, HubSpot. Its industry pages cover software, professional services, recruitment, manufacturing, automotive, real estate and non-profit. Logos include Autotrader, University of Cambridge, Ocado, Markel and the Canadian Red Cross. With offices in the UK, Ireland, the Netherlands and Canada, it suits buyers in those regions. Its RevOps page mentions only HubSpot, so Salesforce-led teams are outside its stated scope.

Its RevOps page describes three pillars: strategy (roadmap, workflow mapping, maturity assessment), implementation of data structures and systems, and enablement through training, audits and ongoing support. Process work includes mapping pipeline stage ownership, standardising handoffs and building a shared metrics model across marketing, sales and customer success. It offers two engagement types: managed services as an extended team, and fixed-scope projects such as implementations, migrations or advanced configuration delivered to a set timeline.

The about page lists offices across the UK, Europe and Canada but does not name founders, a headquarters city or a founding year beyond the homepage's 10+ years claim.

These are Six & Flow's own claims from its website. We have not verified them independently.

Prices are not published. Its RevOps page offers ongoing managed services or fixed-scope projects such as implementations and migrations, and directs buyers to a contact form. Contract terms are not stated.

Strengths, based on what its site publishes:

Trade-offs to weigh:

RevOps firms vary by CRM focus (HubSpot, Salesforce, or both), by company stage, and by whether they work as a fractional team or on fixed projects. Check partner tier for your CRM, how they handle data migration, and whether they also build pipeline generation or stick to operations.

Six & Flow fits HubSpot companies, particularly in the UK, Europe and Canada, that want implementation, RevOps process work and training from one partner. Ask whether you would be on managed services or a fixed project, who leads your account, and what a typical implementation timeline and budget look like. Ask for case studies with measured outcomes, since the published ones are mostly qualitative. Salesforce-first teams should look for a different partner.
