NovaSolar, a mid-size provider of residential solar panels, had thousands of potential customers sitting in their database. Read how with a little help from Callo they turned them into real revenue ↓
The blind spot
NovaSolar had a goldmine: thousands of contacts who clicked “learn more,” filled a form, or visited the pricing page — but never answered a call or progressed further. These leads were marked as interested, but in reality, nothing was happening. Sales was busy calling new leads and managing quotes — but this “almost-interested” pool was behaving like a ghost town.
The experiment
NovaSolar used Callo to reach out to 4221 leads over one week. Instead of guessing which pitch would work best, they launched several different auto-calling campaigns at once. Each campaign tested a different opening angle: one focused on cost savings, another on green energy benefits, a third on government incentives.
Callo became our secret sales assistant — testing scripts, finding what worked, and handing us only warm prospects

After a week, the team analyzed the call transcripts and response rates in Callo’s dashboard. The data clearly showed that the “cost savings” script outperformed the others by a wide margin, delivering far more positive responses.
The results
NovaSolar doubled down on the winning scenario — and within three weeks, it transformed their cold list into a steady flow of new opportunities:
- 4,221 cold leads reached
- 1,050 (25%) qualified and engaged
- $300,000 added to the pipeline
- Dozens of staff hours saved weekly
By letting Callo do the heavy lifting, NovaSolar turned a dusty contact list into a real revenue stream — without burning out their sales team.
