How it scored
Every dimension is scored against this discipline’s published rubric. Open one to see the claim it was scored on, what the rubric measures there and how much it weighs, and where the evidence came from.
How we scored this
We read the agency’s public record first-hand — its site, pricing, case studies and independent reviews — and score what is checkable: what is published, not how it is phrased. There is no keyword counting or sentiment scoring. The label is a judgment on those facts, which is why each dimension shows the fact that decided it, the band it was judged against, and the sources — so you can check the call, and tell us if you think it is wrong. The full method, and who pays, is on how we vet.
CRM and revenue-process architectureStrong
Strong — 4 of 5 on this rubric’s scale, from Poor (1) to Excellent (5). This dimension carries 18% of the total score.
Benchmark — across the 12 other agencies evaluated in this discipline, this dimension runs Excellent 6 · Strong 6. The typical agency here scores Excellent, and 6 of them score higher than this one.
What this dimension measures: Maps lifecycle stages, objects, routing, scoring, SLAs, and sales/marketing handoffs to the real business.
Scores low — A durable cross-functional architecture scores 4-5; tool-default configuration with no process diagnosis scores 1-2.
What we found — CRM, data architecture, and RevOps are named parts of the HubSpot practice.

Attribution and revenue reportingStrong
Strong — 4 of 5 on this rubric’s scale, from Poor (1) to Excellent (5). This dimension carries 16% of the total score.
Benchmark — across the 12 other agencies evaluated in this discipline, this dimension runs Excellent 2 · Strong 9 · Adequate 1. The typical agency here scores Strong, and 2 of them score higher than this one.
What this dimension measures: Builds trustworthy funnel and revenue reporting with documented definitions and reconciled data.
Scores low — Opportunity/revenue attribution and data QA score 4-5; platform dashboards and MQL vanity score 1-2.
What we found — RevOps measurement is offered, while public attribution cases remain limited.
attribution — working out which marketing touch actually caused a sale. Good practice names its model and its blind spots; bad practice quotes each ad platform’s self-graded numbers, which overlap and overclaim.
funnel — the path from stranger to customer — awareness at the top, purchase at the bottom. “Full-funnel” means owning the whole path, not one stage.
MQL — marketing-qualified lead: a contact marketing flags as promising — a form fill, a download — before anyone from sales has spoken to them. Easy to produce in volume, which is why MQL counts flatter and revenue numbers don’t.
RevOps — revenue operations: the plumbing that connects marketing, sales and the CRM so revenue can be traced to what caused it.
Evidence: vendor stated — the agency’s own claim, recorded as theirs rather than ours.
Implementation outcomes and case evidenceAdequate
Adequate — 3 of 5 on this rubric’s scale, from Poor (1) to Excellent (5). This dimension carries 15% of the total score.
Benchmark — across the 12 other agencies evaluated in this discipline, this dimension runs Excellent 2 · Strong 7 · Adequate 3. The typical agency here scores Strong, and 9 of them score higher than this one.
Scores high — Named clients, independent reviews, and quantified adoption, efficiency, data-quality, pipeline, or reporting outcomes score 4-5.
Scores low — Badges and logo walls without outcomes score 1-2.
What we found — A meaningful review base validates delivery, but hard financial outcomes are sparse. That is between the two bands, which is why it scored Adequate.
pipeline — the dollar value of open, qualified deals sales is working. “Pipeline created” ties marketing to money, where lead counts don’t.

Scores low — Opaque retainers and consultant-owned assets score 1-2.
What we found — Public pricing and standard ownership terms were not located. That is between the two bands, which is why it scored Adequate.
retainer — a fixed monthly fee regardless of hours or output — predictable, but worth tying to a defined scope.
Evidence: unknown
Verdict
Six & Flow clears the bar through a balanced mix of RevOps, data architecture, implementation, security controls, and client enablement. A public review specifically says the team taught the client to reproduce work independently, which is unusually relevant to handoff risk.
Outcome evidence is less financially concrete than at the leaders, and pricing is not public. Use a discovery sprint to confirm attribution design, integration ownership, and support boundaries.
