Volley builds the best voice-controlled games and entertainment experiences for Amazon Alexa, Google Assistant, smartphones, and Fire TVs. Popular Volley voice games include Song Quiz, Jeopardy!, and The Price Is Right. Our voice apps are used by millions of people every month. We believe voice control will become the main way people access entertainment in their bedrooms, kitchens, living rooms, and cars, and our goal is to become the "Netflix of Voice" for this emerging category of devices. Volley was founded by Max Child and James Wilsterman in 2016. We're a 60+ person hybrid remote/in-person company, headquartered in the Hayes Valley neighborhood of San Francisco. While we work to make home entertainment more accessible and engaging, we like to have fun along the way, with team lunches, Friday happy hours, and very active #food and #pets slack channels. If any of this sounds fun to you (we promise it is), come join us! Read more about Volley's culture and mission here: volleythat.com/post/volley-mission-culture-and-what-we-create

We believe in enabling humans to interact with the things around them in the same way we interact with each other: by speaking naturally to mobile phones, cars, TVs, music speakers, coffee machines, and every other part of the emerging 'connected' world. Our latest product, Hound, leverages our Speech-to-MeaningTM technology to showcase a ground-breaking smartphone experience. Our SoundHound product applies our technology to music, enabling people to discover, explore, and share the music around them, and even find the name of that song stuck in their heads by singing or humming. And through the Houndify platform, we empower developers to be part of the speech-to-meaning revolution.

Pindrop® Protect provides a risk score and call intelligence to the call center in the first few seconds of each call. The risk score — along with the analysis of the caller’s voice, device, and behavior — is provided to the call center’s fraud analyst team for further investigation. Pindrop’s proprietary machine learning algorithms then use feedback from the investigation to maximize solution performance. Pindrop® Passport evaluates call center interactions in real-time to passively authenticate legitimate customers. Passport runs in the background of every call, combining patented Phoneprinting™ technology with proprietary Deep Voice™ biometrics to determine if a caller has the right device, voice, and behavior to access an account. Whether callers use voice or touch-tone interactions within the IVR — or opt to speak to an agent — Pindrop credentials follow customers across the lifecycle of each call.
