Independent Reviews & Ratings of Marketing Agencies
The marketing agencies worth hiring — and the ones to avoid, across 31 disciplines. Scored on published rubrics, never pay-to-rank.
Ranked from our set, with the ones we reject shown in the open.
This is what a verdict looks like.
All 734 evaluations →Three disciplines, the same rubric, published in full and free to read. Every agency in a discipline is scored on the same dimensions, so two of these are directly comparable.

Fusepoint Insights
Strong fit · 3.6- Good at

- Incrementality and experiment capabilityExcellent
- Named work and demonstrated outcomesStrong
- Data requirements and independenceAdequate
- Deliverable and cadence clarityStrong
- Pricing transparencyWeak
- References and review baseWeak
Every dimension the rubric scores, at the label it was given — the same bar, and the same words, as the agency’s own page. A dimension reading “not disclosed” is one we could not find, not one we found and judged.

All evaluations →Same rubric for everyone, and the whole review is published — the agencies we would recommend and the ones we could not.
Every marketing discipline, vetted the same way.
Most directories are paid placement. Ours is a set we cut from.
Nobody buys their way in. The only way onto the list is to survive the review, and the reviews are public. We're a buyer's agent — if we broker a hire for you, you pay us, and we never take a fee from the agencies we rank.
Who vets this, and how.
Most places that "rank" agencies are paid by the agencies. Directories sell placement, review sites sell badges, and you end up with a leaderboard of whoever spent the most. Koolav is the inverse: the agencies pay us nothing, buyers do, and every verdict is analysis of public evidence you can trace and check yourself.
Think a call is wrong — including if you are the agency it is about? Write to hello@koolav.com. We re-review and publish the result either way, and there is no paid path to a different answer.
The standard, using outbound as the example
Every discipline has its own published rubric, weighted so the things that actually decide that engagement count most — deliverability decides an outbound engagement and is irrelevant to a CRO one. The weights below are the outbound rubric, shown as an example. See the full method and every rubric →
What counts as evidence
Only public, checkable sources: the agency's own site, case studies, and aggregated reviews from G2, Clutch, Trustpilot, and Reddit. Every factor shows its sources. Where a claim is the agency's own and we couldn't independently confirm it, we mark it inferred rather than verified.
Kept current, dated honestly
Each evaluation shows the real date it was last vetted. An old date shown honestly beats a fresh one that is decorative. We never stamp "updated today" on stale work. When evidence shifts, the verdict moves and the record says what changed.
How we stay neutral
Agencies never pay — not for a listing, not for placement, not to change a verdict. Reading the whole vetted set is free. We never take a cent from the agencies we rank, and the ones we cut are named in the open, which is the part a paid directory can never do.
The limits
Every evaluation is informed opinion based on public information, not a statement of fact, and not a guarantee of your results. Any agency can respond to its evaluation and we publish the response alongside. If you are an agency and think we got something wrong, email us — we will re-review and publish the result either way, and there is no paid path to a different answer.

Factors, weighted — the ones that decide the hire come first.
Have Koolav act as your buyer's agent: we reach out, pressure-test them on your specifics, negotiate a scoped start, and hand you a ready decision. You approve everything. We agree a flat fee upfront and never take a cent from the agency.
Saving also watches: we re-check saved agencies and email you if the evidence shifts.
Send us what we got wrong and the link that shows it. We re-read the site and reply either way.
Evidence moves a verdict. Money never does — no agency pays us for a listing, a placement, or a re-review. Whatever we conclude we publish, including that the verdict stands.
Analysis of public information, vetted on the date shown — opinion, not a statement of fact. The vendor may respond to this evaluation; vendor responses are published alongside.

Have Koolav act as your buyer's agent — we do the outreach and broker the engagement for a flat fee, and never take money from the agency. Or go direct; either way the vetting is yours to keep.
