ZoomInfo's Secret Weapon for Custom Data
A 9-person team inside the data giant quietly building bespoke GTM strategies for enterprises
While ZoomInfo dominates the $12B B2B data market, they're quietly deploying a specialized SWAT team to solve the hardest data problems. Tellwise isn't just another vendor—it's ZoomInfo's elite data concierge, turning raw intelligence into revenue.
"They're not selling data—they're selling outcomes. That's the difference between a commodity and a moat."
The Boutique Inside the Behemoth
Tellwise operates like a data agency embedded within a data empire. With just 9 employees serving enterprise clients, they've achieved a staggering $700K revenue per employee—nearly 5x the industry average for B2B services. This isn't scale through automation; it's precision through expertise. They're ZoomInfo's answer to 'we need something you don't offer out of the box.'
The Custom Data Revolution
The B2B data market is bifurcating. On one side: self-serve platforms drowning users in dashboards. On the other: bespoke strategists who actually solve problems. Tellwise chose the latter, betting that enterprise buyers don't want more data—they want the *right* data, cleaned, enriched, and ready to drive revenue. It's a high-margin, low-churn model that traditional SaaS can't replicate.
Their tech stack reveals the strategy: Tailwind and Bootstrap for rapid client portal deployment, Zendesk for white-glove support, Datadog for monitoring bespoke workflows. Every tool serves human-driven service, not self-service automation. This is a consulting firm disguised as a tech company, and that's exactly why it works.
- Micro-team, massive leverage: 9 people generating $700K/employee
- Zero organic traffic = zero inbound marketing. They don't need it.
- Built on ZoomInfo's infrastructure but priced like a strategy consultancy
- No platform lock-in—just outcomes that retain customers
The Unscalable Advantage
Tellwise proves that in a world of AI-generated everything, the most defensible business is still a small team of experts doing impossible work for paying customers.
