About Picslo

Making spontaneous voice connection fun, fast, and global

Picslo Corp is the company behind Walkie Talkie, a social audio app that lets users connect instantly over voice with friends or strangers around the world. Originally built as a fun side project by two engineers, Walkie Talkie exploded in popularity during the pandemic and has since grown into a dynamic platform for spontaneous, real-time conversation.

The app is popular across the globe, including the U.S., France, Mexico, Brazil, and other European and Latin American markets. Users can create private groups, join interest-based channels, or connect one-on-one, with customizable avatars, nicknames, and voice filters that make each interaction playful and personal.

The Problem

Scalable real-time voice for a fast-growing social audio platform

When Dolby.io announced they were ending RTC service, the Walkie Talkie team needed to find a new real-time voice provider. They needed a partner that could support the app’s fast-growing global user base, adapt to frequent feature rollouts, and deliver reliable voice performance across regions and networks.

Because social voice communication sits at the heart of Walkie Talkie, the stakes were high. A new provider needed to offer not just technical parity, but an upgrade in terms of support, flexibility, and innovation.

Key challenges before Agora:

Replacing Dolby.io with a stable, future-proof voice solution

Maintaining ultra-low latency and fast channel switching at scale

Supporting evolving feature sets like peer-to-peer calling, group chat, and voice customization

The Solution

A seamless transition and scalable foundation for voice-first social apps

Agora proved to be the right fit on both the technical and relationship fronts. With Agora’s easy migration, the Picslo team was able to migrate the entire voice infrastructure in just one day, with no user disruption or platform rollback required.

The Walkie Talkie app now uses Agora’s Voice and Signaling SDKs to power both real-time audio and across the app. Agora also enables voice filters which Walkie Talkie offers as a feature to paid subscribers, bolstering the app’s monetization strategy.

Working with the Agora team, including hands-on support from regional solutions engineers, helped make Walkie Talkie’s ongoing addition of new features smoother. Whenever technical challenges arise, Agora is quick to offer troubleshooting or implement updates that meet the team’s evolving needs.
