Zadarma: The 21-Person Powerhouse

How a lean team built a $4.8M global telecom giant

In a world dominated by telecom giants, Zadarma operates as a ghost in the machine. With just 21 employees generating $4.8M in revenue, this isn't just a virtual phone provider—it's a masterclass in efficient scaling. They've built a global communication empire without the traditional overhead.

"Zadarma proves that in the age of AI and automation, you don't need a massive team to build a massive business."

The Invisible Global Network

With 152,038 backlinks and a global rank of #69,753, Zadarma has built an SEO moat that most SaaS companies would envy. Their secret? A product that solves a universal problem—virtual numbers—combined with a free cloud PBX that acts as a loss leader for their premium services. They're not just selling phone numbers; they're selling global access.

The Efficiency Paradox

Here's the kicker: 48% of their traffic comes organically, and 43% is direct. That means 91% of visitors find them without paid ads. For a company of 21 people, this is an operational miracle. They've turned their website into a self-sustaining acquisition engine, where every feature—from call tracking to speech analytics—feeds the next customer.

The Trustpilot rating of 3.4/5 from 693 reviews reveals a nuanced story. It's not perfect, but it's resilient. For a telecom service dealing with global regulations and technical complexities, this rating suggests a company that delivers on its core promise while navigating the messy reality of international telephony.

  • Free cloud PBX as a customer acquisition funnel
  • 100+ countries with local numbers—no geographical constraints
  • Built-in CRM and video conferencing reduces churn
  • Speech analytics and call tracking for enterprise upsells

The Lean Telecom Blueprint

Zadarma isn't just competing with giants—they're outmaneuvering them with surgical precision. For founders and investors, this is a case study in building a revenue machine that scales without the bloat. The future of B2B telecom isn't about having the most people; it's about having the smartest system.

Integrates perfectly with our CRM

we use Pipedrive and Zadarma connects smoothly. Every call gets logged instantly even missed ones. My sales team doesn’t need to take manual notes anymore. That’s a real time-saver honestly. It keeps our data clean and customers happy.

Thank you for your feedback! We’re glad to hear Zadarma is saving your team time and keeping your CRM data organized.

Suitable for freelancers and consultants

I’m a solo consultant and Zadarma gives me a professional phone setup without the overhead. Clients never notice it’s VoIP. The call quality is great even when I’m abroad. I like that I can buy a local number anywhere in minutes. It just makes me look more legit.

Company Response1/13/2026

Thank you very much for your kind feedback. We’re pleased to hear that Zadarma supports your work as a solo consultant and helps you maintain a professional image. We truly appreciate your trust in our service.

Slightly outdated design but strong system

The control panel looks a bit 2010 I won’t lie. But it’s fast and functions well so I can’t complain much. Everything is clearly labeled even advanced options. Performance-wise it’s excellent. I’d rather have a stable service than a pretty one that breaks.

Company Response1/11/2026

Thank you for your kind feedback. We’re delighted to hear that the system’s performance and clarity meet your expectations. We also appreciate your note on the design and will keep it in mind as we continue to improve.

Nice tool for distributed teams

Our marketing team works from three countries and Zadarma makes communication much smoother. We use shared numbers so clients always reach someone. The call forwarding feature is super flexible. Sometimes there’s a half-second lag but it’s really minor. It’s been a game changer for our remote structure.

Company Response1/9/2026

Thanks for your feedback! We’re glad Zadarma is helping your team stay connected.

Easy to get started no tech headaches

Honestly I thought VoIP setup would be a pain but Zadarma made it super simple. The guide walked me through everything step by step. I didn’t need to call support even once. It worked straight out of the box which is rare. Been using it for 3 months and it’s been totally stable

Company Response1/6/2026

Thank you for sharing your experience! We’re glad to hear the setup was easy and that everything has been running smoothly. We appreciate your feedback!
