Comparison
Growth Layer vs RB2B
RB2B is a dedicated visitor-identification specialist, best known for person-level identification aimed at B2B pipelines. As a specialist it will typically resolve more visitors than Growth Layer. Growth Layer is built for Shopify DTC: it resolves a share of anonymous visitors, syncs matches into Klaviyo and Meta, and pairs that with Klaviyo diagnosis — consent-first, at a lower entry price.
The short version
RB2B focuses on identifying website visitors and is oriented toward B2B go-to-market motions. If your priority is the highest possible resolution of individual visitors, a dedicated specialist typically wins on that single metric. Growth Layer is aimed at DTC email programs: it resolves a share of your anonymous store traffic and feeds it into the Klaviyo and Meta flows you already run, alongside Campaign Copilot's plain-English diagnosis of why your numbers moved.
Match rate: be realistic
Both approaches lean on a third-party identity graph that is US-centric with a variable match rate. A dedicated specialist like RB2B typically resolves a higher share than Growth Layer. If resolving the largest possible number of visitors is the whole job, choose the specialist — we'd rather point you there than overstate what we do.
Where Growth Layer is different
- DTC-shaped — matches sync straight into Klaviyo and Meta Custom Audiences so your existing flows re-engage them.
- Bundled with diagnosis — Campaign Copilot explains why campaigns moved; identity is one half of the product, not the whole of it.
- Consent-first by design — consent + GPC honoured, opt-outs suppressed before sync, pooling patterns not people; GDPR built in.
- Lower entry price and read-only connection — from $39/month, identity on the $79/month tier, connected with your own keys.
Where RB2B may fit better
If you run a B2B motion and need person-level identification wired into a sales pipeline, or you want the highest possible match rate from a dedicated tool, RB2B is the more focused choice. Check rb2b.com for their current capabilities and pricing.
