About

Challenge

Scaling inbound lead qualification across regional franchises

As one of Europe’s first renewable energy providers, enerix has been helping local communities reduce their carbon footprint for nearly 20 years. With a rapidly expanding franchise network, CSO Christoph Pirkl needed to streamline operations and keep enerix ahead in a competitive market.

Unlike most other providers that only have centralized sales teams, enerix’s franchisees manage everything locally. This delivers first-class, in-person support and consulting, but means answering every call isn’t always feasible.

To make sure franchisees respond to every lead, Christoph looked for a call automation solution that could engage with callers naturally, qualify their needs, and connect them with the right contact person.

Crucially, it also needed to be scalable across all 100 franchises while staying cost-efficient. enerix wanted a centralized solution that could be rolled out company-wide, but still allow for easy customization to each franchisee’s regional branding and language.

After evaluating several options that couldn’t fit this criteria, Christoph’s team discovered telli. Following a quick call with the co-founders — who had extensive backgrounds in renewable energy — they decided to jump in.

“When you’re operating in a competitive market, you can’t afford to miss a lead. telli ensures that someone is always there to pick up the phone.”

Solution

AI agents take calls and book consultations around the clock

In only four weeks, enerix launched telli’s inbound call agents for two franchises, with immediate plans to expand to more. Christoph describes onboarding as “smooth, hassle-free, and cost-efficient.”

To set the wheels in motion, the telli team completed a turnkey integration with each franchise’s CRM and appointment booking systems and fine-tuned their LLM models to match enerix’s tone and workflows.

Today, telli agents are always on standby, ready to:

• Answer inbound calls, field questions, grasp intent, and filter out any irrelevant callers (like telemarketers). This saves enerix’s teams valuable time, enabling them to focus on building relationships and moving opportunities forward.
• Gather qualifying intel, including the caller’s ideal project timeline, budget expectations, product interests, and whether they’ve spoken with a competitor. Having this information upfront gives enerix franchisees a significant head start — enabling more efficient and targeted conversations.
• Route leads to human reps, either instantly transferring them for a consultation or scheduling a callback directly in their calendar. With access to detailed transcripts and AI summaries in advance, the enerix team can step in with full context, continue the conversation seamlessly, and close deals faster.

Callers always know they’re talking to an AI agent, but personal touches — like speaking in local dialects and referencing specific franchisees — quickly build trust. The agents are context-aware and speak with a natural tone, so conversations feel relevant, clear, and personal.

The impact has been immediate: enerix usage doubled month over month — hitting nearly 100% growth in both May and June — as AI agents rapidly scaled across their workflows. Completed calls also doubled in May and nearly doubled again by June, rising from 467 to over 1,600 in just 60 days. This growth reflects enerix’s new, expanded capacity to turn increased demand into valuable customer interactions.

Christoph also highlights the telli team’s impact on enerix’s success. “If I ping them asking for a tweak, it’s not uncommon for it to be implemented in minutes,” he shares. “telli understands our needs so well that our franchisees can just let it run and focus on field work and high-touch customer engagement.”

Now, 15 franchises use telli agents, with significantly more signing up to test it out after a company-wide demo. For small, local teams with ambitious sales goals, telli’s affordable and efficient agents are the ultimate growth driver.

“Our customers like telli for the prompt, personalized service, and our franchisees love it for the convenience and scalability. It’s a win-win all around.”

Results

enerix increases completed call volume by 4x with telli

With telli, enerix’s franchisees manage inbound calls effortlessly — improving customer experience and enabling smoother transitions to personal and customized solutions. Even better? According to Christoph, with the time it saves and the leads it captures, telli basically pays for itself.

The results:

• 4x completed call volume
• 250% increase in call minutes
• 50% of calls fully resolved by telli agent

enerix plans to roll out telli to even more franchisees and experiment with outbound call management. They’re currently developing a new outbound agent who can follow up with inbound leads that enerix receives centrally and book them across franchises. With impressive results already and telli’s ongoing product evolution, the enerix team is confident it will drive even more value across the network.

“The telli team is responsive, iterative, and an absolute joy to work with. I can’t wait to keep scaling our adoption as they continue to rapidly evolve their product.”
