The Company

Redefining how companies convert inbound demand.

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

Three gaps stood between Spara and a scalable GTM engine.

When Spara’s team began building their go-to-market engine, three critical gaps stood in the way:

1. Unreliable CRM Data Spara lacked a single source of truth for accounts and contacts. Clean, enriched data was essential for accurate ICP definition, routing, reporting, and downstream workflows.

2. An Inbound Funnel That Needed Automation Because inbound is core to Spara’s business and product, they needed a fully automated inbound pipeline—one that enriched new leads instantly, routed them correctly, and equipped sales reps with complete context.

3. No Dynamic ICP Prioritization Outbound has become increasingly difficult. Spara needed a way to identify which accounts were actually showing intent—so they could prioritize outreach to the right companies at the right time, instead of relying on static ICP lists or generic outbound volume.

They knew Clay.com could power this infrastructure, but building it correctly required deep experience. Bringing that expertise in-house would be costly, slow, and risky.

The Approach

A Clay-powered GTM operating system, built to hand off.

Spara partnered with FullFunnel to design and build their Clay-powered GTM infrastructure. The partnership gave Spara access to top-tier Clay expertise while allowing their internal team to stay focused on product, customers, and GTM strategy.

What FullFunnel Delivered A Golden Enrichment Engine 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.

Automated Inbound Lead Enrichment Every inbound lead is now enriched instantly with company details, behavioral insights, transcript data from Spara’s platform, and custom scoring. Reps enter conversations with full context—no research required, no redundant questions for buyers.

Dynamic ICP & Intent Tracking FullFunnel built dynamic Clay tables that monitor website traffic trends and key intent signals. Spara can now see which accounts are “heating up,” continuously re-rank their ICP tiers, and time outbound outreach with precision.

Additional GTM Automation FullFunnel also implemented workflows for:

  • Seamless sales → CX handoff
  • Closed-won lookalike targeting
  • Personalized pitch decks
  • Pipeline and call intelligence
  • Social listening
  • Website visitor de-anonymization
All powered through Clay as the central GTM operating system.

Jeremy’s Perspective “FullFunnel built the foundation for what has allowed us to be successful. They taught us how to use Clay the right way so that in a few months, we didn’t have to solely rely on them. Most agencies don’t teach you their methods — but FullFunnel did.”

Why It Works · FullFunnel's Role

Built with the client, not just for them.
