A Clay-powered GTM engine Spara can now run on its own

The Company

Spara is a fast-growing, well-funded startup redefining how companies convert inbound demand. Their platform helps revenue teams engage buyers in real time, extract meaningful context from conversations, and eliminate the traditional friction that slows deals down. As an inbound sales tool, Spara has to demonstrate operational excellence to its own prospects — which meant they needed a clean, dynamic GTM foundation capable of scaling quickly.

The Challenge

Spara lacked a single source of truth for accounts and contacts, needed a fully automated inbound pipeline that could enrich and route new leads instantly, and had no dynamic way to prioritize outbound based on real intent rather than static ICP lists. They knew Clay.com could power this infrastructure, but building it correctly required deep experience that would be costly, slow, and risky to build in-house.

The Approach

Spara partnered with FullFunnel to design and build their Clay-powered GTM infrastructure, giving them access to top-tier Clay expertise while their internal team stayed focused on product, customers, and GTM strategy.

A centralized Clay table that cleans, enriches, and scores every company and contact, ensuring HubSpot consistently receives complete, accurate, and trustworthy data. This became the backbone of Spara's ICP model and GTM reporting.

Every inbound lead is enriched instantly with company details, behavioral insights, transcript data from Spara's platform, and custom scoring, so reps enter conversations with full context.

Dynamic Clay tables monitor website traffic trends and key intent signals, so Spara can see which accounts are "heating up," continuously re-rank ICP tiers, and time outbound outreach with precision.

Workflows for seamless sales-to-CX handoff, closed-won lookalike targeting, personalized pitch decks, pipeline and call intelligence, social listening, and website visitor de-anonymization — all powered through Clay as the central GTM operating system.
