About RoboKiller

We provide everyone with advanced technology so we can work together to create a world without spam.
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 the spam problem for themselves. 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.

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.

Leadership

Meet the people behind the curtain.

Here are just a few of the amazing people who drive our success:
x
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.
Say Hello to Nikola

Elizabeth Ngo
Director of Business Development
I worked in corporate America for a long time. Then, I quit it all to start my own beverage company (as one does, right?). Now, I’m living out my core values by helping a company I love build secure and trusted products and services that reach everyone and every device — everywhere.

Accomplishments

We’d like to thank the academy (and our users).

What matters most to us is that we’ve empowered our users to take back control of their time, privacy, and safety. But we’re also proud of our work, the awards we’ve won, and the great reviews RoboKiller has received.
