The Revenue Operations Challenge

Wholesale and B2B contacts leak into consumer email flows, or the reverse.

HubSpot and Klaviyo hold different versions of the same person.

Consent and suppression lists drift apart between the two platforms.

For £10M+ B2B companies, this isn't just inefficiency—it's lost revenue, missed opportunities, and frustrated teams who can't deliver the growth your board expects.

Klaviyo & HubSpot integration: FAQs

Can Klaviyo and HubSpot work together?

Yes. The engineering question is audience governance: which contacts belong to which system, and how consent stays consistent. That is what we build.

What does a Klaviyo integration cost?

Fixed-price from £4k for a governed contact and consent sync.

We run Shopify too. Does that change the build?

Usually it strengthens it; we design the three-way data flow so each platform keeps a clear role.
