Speed-to-lead decides the deal
Portal leads (e.g. from comparison sites) go out to several solar companies at once. Whoever calls first gets the appointment - but nobody can sit by the phone all day.

The Reality
This is costing Solar & HVAC companies revenue every day
B2B outreach keeps slipping
Cold outreach to new commercial customers is exhausting and unpopular - which is exactly why it happens too rarely and too inconsistently.
More inquiries than capacity
During peak season, more inquiries come in than your team can qualify and schedule. Good leads go cold while they wait.

Real companies that let Frank make calls for them every day.
"With Frank, we've managed to bring old contacts back to life and turn them into new appointments - completely independent of our team's time."
Benjamin Ziegler
Managing Director, 360 Energiesysteme
"Before using SalesFrank, I was very skeptical and didn't believe it would really work. I was proven wrong in the best possible way."
Dennis Hemesath
Managing Director, festpreishaus.de
"Before Frank, we only called existing customers irregularly, and kept losing customers to the competition as a result. Now customers come back to our store on their own, without constant follow-up calls."

FAQ
Frequently asked questions about the AI phone assistant for Solar & HVAC
How fast does Frank call back a new solar lead?
Within seconds, around the clock. Especially with portal leads that get sold to multiple companies in parallel, speed-to-lead decides the outcome - whoever calls first gets the appointment.
Does Frank understand technical questions about solar, storage, or heat pumps?
Frank answers based on your call script and the information we set up for him. For deep technical questions, he qualifies the interest and hands off to your specialist or books the appointment - that's exactly what he's there for.
Does Frank reduce no-shows for on-site surveys?
Yes. Frank sends timely reminders for site-survey and online consultation appointments, confirms them, or reschedules directly - which noticeably lowers the no-show rate.
Can you call consumer (B2C) contacts too?
B2C outreach requires consent. Form and portal leads typically come with an opt-in already in place. We'll clarify exactly what you can do and how during setup.
Does the person on the phone realize Frank is an AI?
If asked, Frank transparently identifies himself as a digital assistant - this is also required by the EU AI Act. What matters isn't whether it sounds human, but whether the conversation is handled meaningfully and reaches its goal. Acceptance of AI on the phone is also rising steadily.
What happens with a question that isn't covered in the script?
A language model runs in the background. Even without a scripted answer, Frank doesn't drop out of the conversation - he responds sensibly and steers toward the goal. The better the script, the more precise he is - but Frank doesn't stall even without a perfect briefing.
