Hamster Garage review

Excellent — 5 of 5 on this rubric’s scale, from Poor (1) to Excellent (5). This dimension carries 25% of the total score.

Benchmark — across the 14 other agencies evaluated in this discipline, this dimension runs Excellent 4 · Strong 8 · Adequate 1 · Weak 1. The typical agency here scores Strong, and none scores higher than this one.

What this dimension measures: Attributable programs at a stated scale: named brands, described program size, publisher counts, revenue managed. Treat headline revenue figures as vendor-stated unless a client is named. Where a firm names the networks its programs run on, that is checkable detail and should be credited.

Scores high — Named clients with described program work score 4-5.

Scores low — Anonymised case studies score 2-3.

What we found — Thirteen case studies, most with the client named: Xero, Bloomscape, Burrow, VEED.IO, Oars + Alps, Redtiger, Lepro, Faire. Program size is described, not just outcome percentages: Xero went 117 to 400+ partners over 18 months with a Q2 2025 partner-mix breakdown (HG-managed 49.3%, global affiliate groups 19.4%, Impact partners 17.7%, strategic 13.7%) and CPA falling from $778 to $399; Bloomscape held $1.64M revenue through a migration while active publishers went 39 to 78. The networks each program runs on are named (PartnerStack, Impact), which the rubric treats as checkable detail. The /client page shows 40+ logos including Coinbase, Canva, Reddit, Faire, Masterclass, Replit, Philips, Hopper. Two of the named clients are independently corroborated: the Clutch profile carries reviews attributed to a Partnerships Manager at Xero and a Channel Marketing Manager at BILL. Headline aggregate claims (7x average program ROAS, $37B+ client funding raised) remain vendor-stated. That is the high band above, which is why it scored Excellent.

On the record — “Clutch profile shows 4.8 out of 5 from 8 verified reviews, 10-49 employees, $5,000+ minimum project size with $10,000-$49,999 the most common range; reviewers are attributed to Xero and BILL, independently corroborating two named client relationships.” clutch.co ↗

On the record — “Xero program: 117 to 400+ partners in 18 months, CPA from $778 to $399, run on PartnerStack and Impact at roughly 70/30, with monthly partner audits, BrandVerity trademark monitoring, quarterly reviews by partner type and geography and LTV, 57 partners corrected and 10+ subnetworks removed.” hamstergarage.com ↗

ROAS — return on ad spend: revenue per dollar of advertising. Platform-reported ROAS overstates; independently measured ROAS is the honest version.

Evidence: partly checkable — corroborated in part against the sources below; the remainder rests on the agency’s own account.

Excellent — 5 of 5 on this rubric’s scale, from Poor (1) to Excellent (5). This dimension carries 20% of the total score.

Benchmark — across the 14 other agencies evaluated in this discipline, this dimension runs Excellent 1 · Strong 6 · Adequate 5 · Weak 2. The typical agency here scores Strong, and none scores higher than this one.

What this dimension measures: The dimension that separates a managed channel from a paid-for coupon leak. Look for a stated position on incrementality — how the firm distinguishes affiliate-driven demand from demand that would have converted anyway — and on policing: coupon and loyalty extension monitoring, trademark bidding enforcement, cookie-stuffing and attribution-hijack detection, publisher vetting. Policing only, with no incrementality position, scores 3.

Scores high — A named policy on BOTH scores 4-5.

Scores low — Silence on both scores 1-2 and should be named plainly: an unpoliced program reliably pays commission on traffic the brand already owned.

What we found — A named position on both, and the rarest thing found in this category. Incrementality: a dedicated published article defines it as sales that would not have occurred without the channel, prescribes hold-out tests (pausing a partner tier to benchmark), matched-market analysis, and new-vs-returning / AOV / LTV reads by partner type, and ranks partner tiers by incrementality -- content high, coupon mixed, cashback low. It is applied in the case studies rather than left as theory: the ride-sharing program cut commissions to cashback and coupon partners for a stated $2,001,000 in savings alongside 7% program growth, and Bloomscape's recruitment was explicitly widened beyond low-funnel for improved incrementality. Policing: a separate published article names cookie stuffing (iframes, pop-unders, extensions), attribution hijack by browser extensions, trademark bidding, lead fraud and click fraud via residential proxies, with detection by IP clustering, browser fingerprinting and interaction-speed analysis. Again evidenced in practice -- the Xero program runs monthly partner audits with BrandVerity trademark monitoring and reports zero paid-search brand violations, 57 partners corrected and 10+ subnetworks removed; the graphic-design-platform program forced transparency agreements on 11 subnetworks, used SharedID plus Impact Protect and SimilarWeb, surfaced 165+ hidden sub-affiliates to a 61.1% transparency rate and removed 2 partners for compliance violations. That is the high band above, which is why it scored Excellent.

On the record — “Publishes a fraud policing article naming cookie stuffing, browser-extension attribution hijack, trademark bidding, lead fraud and click fraud, with detection by IP clustering, browser fingerprinting and interaction-speed analysis.” hamstergarage.com ↗

On the record — “Publishes a standalone incrementality method: hold-out tests, matched-market analysis, new-vs-returning and AOV and LTV reads by partner type, with content partners rated high incrementality, coupon mixed, cashback low.” hamstergarage.com ↗

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.

LTV — lifetime value: the revenue a customer generates over the whole relationship, judged against what they cost to acquire.

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.

Evidence: partly checkable — corroborated in part against the sources below; the remainder rests on the agency’s own account.

Excellent — 5 of 5 on this rubric’s scale, from Poor (1) to Excellent (5). This dimension carries 15% of the total score.

Benchmark — across the 14 other agencies evaluated in this discipline, this dimension runs Excellent 1 · Strong 11 · Adequate 2. The typical agency here scores Strong, and none scores higher than this one.

What this dimension measures: Who the firm can actually bring: named publisher types and any evidenced relationships beyond the obvious coupon and cashback tier — content publishers, review sites, newsletters, comparison shopping, B2B referral partners.

Scores high — Evidence of recruiting beyond coupon/loyalty scores 4-5.

Scores low — A roster that is entirely coupon and cashback scores 2-3; that is the easiest tier to recruit and the least incremental, and the verdict should say so.

What we found — Recruitment demonstrably reaches past the coupon and cashback tier. The Xero program names content creators, influencers, business deal platforms, B2B publishers, SaaS communities, regional content partners and media outlets across four markets (North America 700+ orgs, Australia 330+, UK 120+, New Zealand 40+). The library carries separate published pieces on upper-funnel partners, mid- and lower-funnel partners, and publisher traffic/SEO quality analysis, so the taxonomy is a stated method rather than a slogan. Two programs are documented moving away from the coupon tier rather than toward it. The 100,000+ partner connections figure is vendor-stated and not checkable. That is the high band above, which is why it scored Excellent.

B2B — business-to-business: selling to companies rather than consumers — longer deals, more decision-makers.

SaaS — software as a service: subscription software; as a client type it brings recurring revenue and metrics like churn and lifetime value.

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.

Evidence: partly checkable — corroborated in part against the sources below; the remainder rests on the agency’s own account.

Strong — 4 of 5 on this rubric’s scale, from Poor (1) to Excellent (5). This dimension carries 15% of the total score.

Benchmark — across the 14 other agencies evaluated in this discipline, this dimension runs Excellent 2 · Strong 7 · Adequate 5. The typical agency here scores Strong, and 2 of them score higher than this one.

What this dimension measures: Which networks and platforms the firm operates on (Impact, PartnerStack, CJ, Awin, Rakuten, ShareASale, Everflow and the rest), whether it can migrate a program between them, and whether it works in the client's own account. Note whether the client owns the network account, since that determines whether the program is portable.

Scores high — Named multi-network capability plus migration experience scores 4-5.

Scores low — A single network with no migration path scores 2-3.

What we found — Multi-network operation is evidenced, not just listed: the Xero program ran on PartnerStack from July 2024 and added Impact in March 2025 with a 70/30 partner split across the two. Migration experience is documented -- Bloomscape was moved off a legacy network that was simultaneously its platform and its agency onto Impact, 100+ partners in five months. Claimed Platinum status with Impact and Gold Partner status with PartnerStack; those tiers are vendor-stated and were not confirmed on the platforms' own directories. A published platform guide discusses CJ, Rakuten, Awin, ShareASale, Partnerize, Impact, PartnerStack, FirstPromoter, Rewardful, Levanta and Partner Boost, plus Amazon and TikTok Shop lines. Held below Excellent for the ownership question the rubric asks here: nothing on the site states whether the client holds the network contract. The Bloomscape write-up describes the end state as a SaaS platform plus an agency retainer, which implies a client-held platform account, but that is an inference from one case, not a published term. That is the high band above, which is why it scored Strong.

On the record — “Bloomscape migration off a legacy network that was both platform and agency onto Impact, 100+ partners in five months, $1.64M revenue maintained, active publishers 39 to 78, recruitment widened beyond low-funnel explicitly for incrementality.” hamstergarage.com ↗

On the record — “The only fee-model statement located anywhere on the site: custom scoped engagements, retainer plus performance components, no public pricing tiers. No rate, percentage or contract term is published.” hamstergarage.com ↗

SaaS — software as a service: subscription software; as a client type it brings recurring revenue and metrics like churn and lifetime value.

retainer — a fixed monthly fee regardless of hours or output — predictable, but worth tying to a defined scope.

Evidence: partly checkable — corroborated in part against the sources below; the remainder rests on the agency’s own account.

Weak — 2 of 5 on this rubric’s scale, from Poor (1) to Excellent (5). This dimension carries 15% of the total score.

Benchmark — across the 14 other agencies evaluated in this discipline, this dimension runs Strong 1 · Adequate 4 · Weak 9. The typical agency here scores Weak, and 5 of them score higher than this one.

What this dimension measures: How the firm is paid — flat retainer, percentage of affiliate revenue, hybrid — and who owns the program, the publisher relationships and the account at exit. A percentage-of-revenue model is not a defect but carries an obvious incentive to grow attributed revenue whether or not it is incremental, and where a firm charges that way AND is silent on incrementality, the combination should be named.

Scores high — A published fee model plus explicit client ownership scores 4-5.

Scores low — Silence on ownership scores 2.

What we found — The shape of the model is stated in one line on their own comparison article -- custom scoped engagements, retainer plus performance components, no public pricing tiers -- and their Clutch listing gives a $5,000+ minimum with $10,000-$49,999 as the most common project size, which is the only number a buyer can read. No rate card, no percentage, no contract term. On ownership the site is silent across every page read: who holds the network account, who owns the publisher relationships, and what transfers at exit are never addressed, including on the case study that is itself about a migration. The rubric scores silence on ownership at 2 and that is the binding fact here. The mitigating point is that the usual danger of a performance-linked fee -- an incentive to grow attributed revenue whether or not it is incremental -- is the one thing this firm is not silent about; it publishes an incrementality method and has documented cutting its own attributed revenue base on two programs. That is what the low band describes, which is why it scored Weak.

Stronger here: Advertise Purple scores Strong on the same dimension.

Strong — 4 of 5 on this rubric’s scale, from Poor (1) to Excellent (5). This dimension carries 5% of the total score.

Benchmark — across the 14 other agencies evaluated in this discipline, this dimension runs Strong 3 · Adequate 8 · Weak 3. The typical agency here scores Adequate, and none scores higher than this one.

What this dimension measures: What the client receives and how often: partner-level reporting, incrementality reads, payout reconciliation, a stated review cadence.

Scores high — Defined reporting with a named cadence scores 4-5.

Scores low — Undefined scores 2.

What we found — A cadence is named, though inside case studies rather than as a published client deliverable. The Xero program states monthly partner audits and quarterly performance reviews segmented by partner type, geography and customer lifetime value; the subnetwork transparency work put mandatory quarterly reporting into 11 partner agreements. Partner-level reporting is evidenced by the published partner-mix percentages. What a standard engagement includes -- dashboard access, payout reconciliation, who attends the review -- is not published anywhere on the services pages. That is the high band above, which is why it scored Strong.

On the record — “Xero program: 117 to 400+ partners in 18 months, CPA from $778 to $399, run on PartnerStack and Impact at roughly 70/30, with monthly partner audits, BrandVerity trademark monitoring, quarterly reviews by partner type and geography and LTV, 57 partners corrected and 10+ subnetworks removed.” hamstergarage.com ↗

On the record — “Subnetwork transparency program: transparency agreements with 11 subnetworks including mandatory quarterly reporting, SharedID plus Impact Protect and SimilarWeb, 165+ hidden sub-affiliates identified, 61.1% overall transparency rate with per-network range 2.5% to 98.9%, 2 partners removed for compliance violations.” hamstergarage.com ↗

deliverability — deliverability: whether cold email actually lands in the inbox rather than spam. The tell is infrastructure talk — warmed sending domains kept separate from your main domain — because a burned domain outlasts the engagement.

Evidence: vendor stated — the agency’s own claim, recorded as theirs rather than ours.

Adequate — 3 of 5 on this rubric’s scale, from Poor (1) to Excellent (5). This dimension carries 5% of the total score.

Benchmark — across the 14 other agencies evaluated in this discipline, this dimension runs Strong 4 · Adequate 8 · Weak 2. The typical agency here scores Adequate, and 4 of them score higher than this one.

What this dimension measures: Independent, verified reviews or industry recognition that can be read first-hand.

Scores low — A substantial verified base scores 4-5; a handful scores 2-3; none located scores 2.

What we found — Clutch profile read first-hand: 4.8 out of 5 from 8 verified reviews, team size 10-49. Reviewers are identified by role and employer, including a Partnerships Manager at Xero and a Channel Marketing Manager at BILL, which corroborates two client relationships independently of the site. Eight is a handful rather than a substantial base. One review names forecasting accuracy on new partnership opportunities as a weakness. Awards (US Partnership Awards boutique category) surfaced in search but were not read on an awarding body's own site, so no award claim is credited here.

On the record — “Clutch profile shows 4.8 out of 5 from 8 verified reviews, 10-49 employees, $5,000+ minimum project size with $10,000-$49,999 the most common range; reviewers are attributed to Xero and BILL, independently corroborating two named client relationships.” clutch.co ↗
