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. It is consent-first and has 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 that, Campaign Copilot explains in plain English 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, RB2B is the more focused choice. The same goes if you want the highest possible match rate from a dedicated tool. Check rb2b.com for their current capabilities and pricing.
