telli leverages Verbatim-powered customer stories in 100% of outbound deals

Challenge

Building trust in an emerging AI category without a content function

telli’s business is grounded in a clear thesis: AI voice agents will transform how B2C businesses handle phone-based customer interactions. But voice AI is still a young category, leaving most business leaders understandably skeptical that it can handle real customer conversations.

Ennie Raguse, Founders Associate, knew the only way to change that perception was to show telli in action and demonstrate that voice AI could be genuinely customer-first. The strongest proof would be stories of real B2C brands whose callers were getting faster answers, higher satisfaction scores, and human-sounding conversations from AI agents at scale.

The content would have to serve two audiences: prospects who had never heard of AI voice agents and needed basic education, and buyers further along who wanted proof like metrics, implementation details, and before-and-after results.

The obstacle was bandwidth. Ennie was covering ops, finance, and growth, while supporting the co-founders. She knew content mattered, but there was no one to own it. "We even considered bringing someone on board, but these things take a lot of time, and we wanted to move very quickly,”  shares Ennie.

While speed was important, it couldn’t come at the expense of their customer relationships. Because telli’s AI voice agents take real customer calls and handle sensitive information, companies are effectively handing over a piece of their customer experience, which only works if they trust telli to represent them well. That set a high bar for any content partner who would be interacting with these customers. They had to own the process, protect those relationships, and still deliver case studies quickly.

Instead of running a long search process, Ennie and the founders followed a trusted contact’s referral straight to Verbatim. When they saw Verbatim’s case study deck, with recognizable brands and the kind of narrative depth they were looking for, it quickly became clear this was the specialist partner they needed.

“We have very close relationships with our partners, so it was crucial that we feel they’re in good hands. With Verbatim, our customers are happy, and the output speaks for itself.”

Solution

End-to-end content production that keeps customer relationships intact

Verbatim took ownership from the start, walking telli through a content plan and clearly outlining the support and resources they would need. "After the first call, we knew this could work," Ennie recalls. 

And Verbatim didn't disappear after onboarding. The team keeps the content calendar updated, maintains regular communication, and proposes new angles — like industry-specific case studies based on telli's expanding customer base.

Ennie’s involvement stays intentionally lightweight. She connects telli’s customers with Verbatim, who handles everything from there: scheduling and conducting the interview, drafting the case study, and routing it to Ennie for review. This means Ennie stays focused on ops, finance, and growth, getting clear progress updates without having to manage the process herself.

On the customer side, the experience was even better than Ennie had hoped. "Verbatim gets our customers to open up," Ennie highlights. "Their structured interviews even give customers a chance to bring their own brand into the story, which is a nice touch."

And the content assets have continuously delivered. They're accessible enough to serve as an entry point for someone unfamiliar with AI voice technology, and they include the numbers and specifics that close deals. telli’s sales team now sends them to prospects before initial calls — by the time buyers get on the phone, they already understand what telli can do for them.

“Verbatim’s case studies are easy to read, even for someone new to voice AI, but they still go deep on the numbers and on what changed before and after telli.”

Results

telli ships 9 content assets in 5 months with Verbatim

What started as a capacity problem is now a competitive advantage. telli has a library of customer stories spanning multiple industries, ready to share with prospects at every stage in the sales cycle.

The partnership delivered:

• 100% of deals now receive case studies before first call
• 14 content assets published in the first 5 months

As telli continues to grow its customer base and expand its offerings, the team expects case studies to remain a key part of its marketing efforts, with plenty of room to keep bringing new customer stories to life.

“We simply didn’t have the resources to ship case studies on our own. Working with Verbatim gives us leverage we otherwise wouldn’t have had.”
