A robot that never says “I don’t know”

TechHouse is a consumer electronics retailer that prides itself on fast service and expert advice. With dozens of daily inquiries — from “Is this model in stock?” to “Can I return a purchase?” — the phone was their main sales and support channel.

But as the company grew, so did the number of missed calls. After-hours requests went unanswered, agents juggled too many lines, and potential buyers often gave up before reaching someone. Each missed call meant a missed sale — and a dent in customer trust.

When growing demand became too loud to handle

TechHouse’s support team was drowning in calls. Customers wanted to know everything: delivery status, product compatibility, warranty terms.
As a result:

  • 63% of calls were simple FAQ-type questions,
  • average wait time hit 10–15 minutes,
  • and the company’s NPS dropped by 22 points in one quarter

From chaos to calm — with an always-on voice assistant

Instead of trying to handle every question manually, TechHouse built a simple IVR menu in Callo to guide callers to the right topic — “orders”, “technical help”, or “product info”.
The robot could:

  • answer common questions about warranties, delivery times, or compatibility,
  • fetch real-time information from the CRM (like tracking details or invoice numbers),
  • and recognize when a question didn’t fit the script, handing the call to a human instantly.

For customers, it felt smooth — no robotic loops or endless menus.
For the team, it meant fewer repetitive tasks and more focus on tricky cases that actually needed expertise.
After a short pilot, TechHouse expanded the setup: new product launches automatically added fresh data to the agent’s “brain”, so it always stayed up to date without manual edits.

Our clients get the right answer with no staff involved whatsoever. It’s like adding another team — one that never sleeps

Sofia K., Head of Support, TechHouse

After a month with Callo

  • 68% of all calls now resolved instantly without staff involvement
  • Average response time dropped from 12 minutes to under 3
  • The team saved 2+ hours daily for complex cases
  • Customer satisfaction rebounded — NPS rose to +54

How spotting shifting customer sentiment helped

Apex bank, a mid-sized regional bank, had solid client retention. But leadership felt uneasy. Competitors were rolling out flashy mobile features, and rumors suggested younger clients were considering switching. The bank’s standard quarterly surveys didn’t reveal much — customers mostly ticked “satisfied” and left no comments.

When five stars aren’t enough

A hotel chain was getting plenty of star ratings, but no real explanation. Email surveys returned low reply rates and online reviews only showed extremes. The team needed detailed, on-the-record insights across locations — the kind of feedback you can act on — but traditional surveys weren’t cutting it.

Keep loosing members? Just ask why

FitZone Gym noticed a worrying trend: more and more members were canceling their subscriptions after just a few months. Exit surveys sent by email went mostly unanswered, and front desk staff rarely asked people leaving for their real reasons. The management team was left guessing — was it pricing, equipment, or maybe poor class scheduling? Without clear answers, they couldn’t stop the churn.

A clinic wanted honest feedback & stopped handing out paper forms

For years, BrightSmile Dental relied on paper surveys left at the reception desk. Most patients were in a hurry to leave, and only a handful bothered to fill them out. Even those who did were often polite rather than honest. The clinic had no real way to know what patients truly thought — or why some never booked a follow-up

How SproutBox validates new ideas in a day

When you sell meal kits, trends move fast. SproutBox’s marketing team had plenty of ideas—new recipes, bundle offers, a “family night” plan—but email polls took weeks and social votes were noisy. By the time answers arrived, the moment (and the budget) had moved on.

Fixit Garage never missed a call again

Fixit Garage was busy all day — repairing cars, handling paperwork, juggling customer questions. But the real problem started after 6 PM, when the phones went silent in the shop — but not for customers. Drivers stuck on the roadside or clients trying to book a morning appointment were left with voicemail. By the time staff called back the next day, many had already gone to a competitor.

NetLink kept customers calm during a sudden outage

NetLink, a regional internet provider, had built a loyal subscriber base — until unexpected outages started to cause trouble. Every time a server crashed, hundreds of clients picked up the phone at once. Lines were jammed, support agents scrambled, and the same “What’s going on?” question was answered again and again.

How a small bistro stopped missing orders — and started growing

Most callers wanted the same things — today’s menu, delivery time, and “extra sauce, please” — but with just two operators on duty, calls piled up fast. By the time someone picked up, some customers had already moved to competitors with faster response times.

TechNova keeps IT teams alert & systems running

TechNova, a fast-growing SaaS company, relied on Slack and email notifications from monitoring tools to inform engineers about outages. But with inboxes overflowing and phones on silent, urgent messages were often missed. Engineers found out about downtime too late — sometimes from angry customers.
