Callyo in the News

  • Callyo Named to 2020 GovTech 100 List for 3rd Consecutive Year

    Callyo, the leading mobile law enforcement software as a service (SaaS) company, is honored to be named to the 2020 GovTech 100 for the 3rd consecutive year.

    The annual list, created by Government Technology News in 2016, compiles the top 100 companies focused on making a difference in state and local government agencies.

    “We’re excited to have been listed a GovTech 100 company for the third year in a row,” said Steve Ressler, President. “Our team is passionate about bringing innovative technology to law enforcement and feel honored to work with our 10,000+ law enforcement agency partners every day.”

    Callyo’s selection to the GovTech 100 continues its great momentum after a record-setting year of growth at Callyo in 2019. In addition to company growth, Chris Bennett, Founder and Chief Product Officer, was recognized as one of Tampa Bay Business Journal's 40 Under 40. There were more than 600 nominations and a record 300 submissions before the field was trimmed to 40 professionals.

  • Spotlight: Callyo is changing the way investigations are done. Advancing mobile technology for law enforcement investigators.

    What was the inspiration behind starting your company?

    My companies leading up to Callyo (pronounced call-ē-ō) increasingly had a focus on helping the public by equipping emergency management with better technology. That crossed into public safety for me at a time when I lived in an area with heavy police presence and found myself routinely chatting with detectives in my neighborhood. I knew I could apply my talents to equip these investigators with modern mobile technology to replace their old hardware -- that’s how the company was born.

    What is your signature product and how does it work?

    10-21 Police Phone improves police-citizen communications and community relations by making officers more accessible (but without giving out personal numbers). It’s a free app that officers can use to call citizens from local numbers, where citizens have the ability to send a push notification requesting a call back. 10-21 diverts millions of calls away from dispatch centers each year.

    Why do you believe your products are essential to your vertical (Police, Fire, EMS, Corrections, Government) community?

    Callyo’s products save valuable time and resources for the communities we serve, making evidence collection safer, easier, and more reliable, in turn increasing prosecution rates all while respecting the privacy of our citizens.

    What has been the biggest challenge your company has faced?

    Like many companies, we face the challenge of deciding which problem or feature to attack next. There are so many areas where we can help, and sometimes deciding which will have the biggest impact on our community isn’t always clear. Callyo continues to invest in new products and engineers while keeping prices affordable to agencies of all sizes.

    What makes your company unique?

    Callyo is unique in that from day one we’ve built a culture where we first became an officer safety company, then a customer service company, then a technology company. We only serve law enforcement and from our first day have had 24/7 customer support with an obsession of helping each officer we come in contact with. When we’re not helping customers, we’re celebrating every holiday and event in our St. Petersburg, Florida office while having a lot of fun. Second, with so many equipment and gadget vendors in the space, Callyo is unique in our mantra that “you shouldn’t need special equipment to do something special.” The smartphone in your pocket is the best possible foundation to unlock limitless lifesaving abilities.

  • Callyo Partners with Sonim to Offer Livestreaming Capabilities on XP8

    CARSON CITY, Nev., June 10, 2019 /PRNewswire/ -- Callyo, the leading mobile law enforcement software as a service (SaaS) company, has announced that they have partnered with Sonim Technologies (NASDAQ: SONM) to integrate Callyo's 10-21 Video onto the Sonim XP8 Android mobile phone.

    Currently serving 150,000+ officers and 10,000+ agencies throughout the country, Callyo's partnership with Sonim brings together two types of first responder technologies. With 10-21 Video on the Sonim XP8, law enforcement officers can rely on a device that is built to withstand extreme conditions all while providing instant video functionality that enhances officer safety in the field. The integration of 10-21 Video allows officers to record video with a click of a button thereby eliminating the need for a standalone camera while on the job. Now officers can use their mobile phone as a dashcam while on patrol, conduct field interviews or go into conceal mode when capturing surveillance all while broadcasting their location and surroundings.

    "We chose to partner with Sonim because of the company's mission-critical technology," said Chris Bennett, Chief Product Officer & Founder of Callyo. "We look forward to expanding functionality and benefits for public safety by bringing our purpose-built law enforcement software to the Sonim purpose-built hardware device."

    The XP8 provides users with an ultra-rugged, easy-to-use experience with its built-in dedicated push-to-talk button, emergency key, long battery life and extra-loud audio. It delivers exceptional toughness by meeting Ingress Protection (IP)-68/69 and Military Standard 810G certifications for hazards, making it waterproof, shockproof, scratchproof and dustproof. The XP8 also integrates a puncture resistant 5" touchscreen that works with gloves or wet fingers and is visible in direct sunlight, while providing up to 35 hours of talk time or 600 hours of standby time.

    Robert Escalle, Sonim's VP of Public Safety Market Segment, welcomed the partnership as a means to demonstrate Sonim's desire to serve those who serve us. "By integrating Callyo's 10-21 video solution onto the XP8, we're able to streamline mobile communications for first responders when seconds count. Having to manage one less device and instant access to video can make all the difference in an emergency situation."
