Mission

Robokiller exists to enable every person to fight back against spam.

We invite you to join us in our quest to live life spam-call-free™. We’re fighting with every tool we’ve got — and we’re sharing our arsenal and expertise with our users, so anyone and everyone can be part of the solution.

That arsenal includes world-class audio fingerprinting, Answer Bots who make it easy to waste scammers’ time, collective identification to take one bad number and block it for everyone, and customizable spam-stopping features that let us dial up or down our defense.

Vision

The future is everyone’s to fix.

We envision a future without robocalls, spam texts, and telemarketing scams. We believe everyone can work together to beat fraudulent actors, defend the vulnerable from villainous activity, and finally find peace for our phones — and ourselves.

Then, we can find a new problem to solve.

Beliefs

Solutions require the right tools.

Control belongs to you.

We believe people should have total control over how they solve spam. That’s why we made the most customizable call blocker available on the market. Robust features let users control exactly how and when Robokiller blocks their calls.

The future is everyone’s to fix.

We’re inviting everyone to the table to solve the spam problem. Users can opt in to provide real-time feedback that trains Robokiller's machine-learning algorithm to become smarter and more effective. To date, the Robokiller community has prevented more than $600 million in losses to phone scams.

Build to solve.

As spammers get sneakier, we get smarter — because we’re here to be the definitive solution for spam today and tomorrow. We don’t consider our work done until we rid the world of robocalls and spam texts, and we’re up for the challenge.

Robokiller screening a phone call for caller name and purpose in real time.

Built to solve

We’re not like other apps.

Our secret weapon is Robokiller’s predictive algorithm, which takes a proactive — not reactive — approach to spam call blocking.

Unlike other services, we don’t wait for customers to report a spam call before blocking one caller at a time. Instead, Robokiller checks incoming calls for the audio fingerprints of spammers, and shuts them down before your phone even rings — all in less than a millisecond. We then store the audio fingerprint in our global database so the scammers can’t strike again.

Our call blocking is 99% effective at stopping spam calls, and our text blocking is 99% effective at halting unwanted messages.

Our story

Long story short, we hate spam.

We created Robokiller because we hate robocalls as much as you do.

To us, robocalls reflect a larger issue: a system that leaves us disempowered and in the dark. Big players who profit from the deluge of spam calls that make our phones unsafe. Companies that sell our phone numbers under the table, while preaching security above board. Laws that can’t keep up with new fraud or phishing ploys. This system takes privacy and control away from individuals — and we want everyone to have the tools to take it back.

Solutions don't solve problems; people do.

With Americans losing billions every year to phone scams, we needed a solution for robocalls yesterday. But we couldn’t do it alone. Robokiller designed powerful, solutions-oriented phone scam fighting technology that anyone can use to solve the spam call problem for themselves and others — because you should have control over who calls you.

Leadership

Meet the people behind the curtain.

Here are just a few of the amazing people who drive our success:

Patrick Falzon

CEO of Teltech

I help push our amazing team toward our goal of delivering forward-thinking and user-friendly mobile solutions that focus on security, practicality, and innovation. In my free time, I love traveling, reading, and long walks on the beach — with my dog, of course.

Say Hello to Patrick

Giulia Porter

Vice President of Marketing

I lead our marketing efforts, and I love nothing better than geeking out on brand and data-driven marketing. In my free time, you can find me traveling, playing around with my camera, and making way too many trips to Target.

Say Hello to Giulia

Matt Mizenko

Senior Vice President of Operations

I've been in mobile since way before it was even a thing; in fact, I built one of the world's first mobile commerce applications! At my core, I am a sausage maker — which means that I drive process and execution. Nothing geeks me out more than starting with a few ideas on a whiteboard that eventually lead to a polished product. I grew up in New Jersey (Rutgers Strong!), but I currently live with my family on a small farm outside Seattle.

Say Hello to Matt

Nikola Breznjak

Vice President of Engineering

I'm responsible for leading mobile and cloud developments, as well as quality assurance. In my spare time, I love playing board games (especially with my two kids and my lovely wife), and I'm aspiring to become Iron Man at some point in the future. I also like to read — but as it turns out, I like to listen to Audible books even more.
