Spear Growth review
A growth agency with 17 strong Clutch reviews and verified funnel improvements, including MQL-to-opportunity and closed-won revenue outcomes.
Pricing: $50–$99 per hour Reported — not published by the agency
Clutch lists 4.9/5 from 17 reviews, a $1,000 minimum, and $50–99 hourly pricing. source ↗
Verdict
Spear Growth is a strong growth and CRO-adjacent candidate when website experimentation must connect directly to demand generation and revenue operations. Verified outcomes are unusually commercial. Buyers seeking a pure experimentation lab should inspect test design, statistics, platform implementation, and the proportion of scope devoted specifically to CRO.

What other platforms say
Strong commercial funnel outcomes and value; pure experimentation depth needs scope verification.
These are other platforms' numbers, not ours. We report them because they are part of the picture, and we do not average them into our score — our score comes from the published rubric above.
Red flags
- Broad growth scope may dilute experimentation specialization
- Platform depth is not clearly public
- Require a CRO-specific test plan and raw-result access
How it scored
Experimentation rigor (valid A/B testing)
CRO and experimentation are present, though not the agency's only discipline.
Conversion research and UX
Funnel diagnosis and conversion work are supported by reviews.
Landing page / site design and dev
Landing-page and conversion implementation capability is public.
Analytics and attribution
Reviews connect funnel stages to opportunities and revenue.
Measurement tied to revenue lift
One review reports $1.25 million in closed-won revenue.
Platform depth (Shopify / Webflow / Next)
Platform-specific depth is not a primary public proof point.
Vertical and stage fit
Strong fit for B2B growth teams.
Contract and pricing transparency
Clutch publishes a $1,000 minimum and $50–99 hourly range.
What we could not verify
- Test statistics, stopping rules, and test velocity
- Platform-specific implementation depth
- CRO share of scope, code ownership, and named developer allocation
