Audio-first communication platform for distributed teams of all sizes. Acquired by Pulse, and then by Mozilla.

Case study

Problem

Real-time communication products are unforgiving: latency, reliability, and UX polish determine whether teams adopt or churn.

Problem: The product needed to support real-time audio interactions while remaining stable under variable network conditions and growing user activity, without a large engineering team.

Solution

Horizon Labs supported the founding product engineering team with an emphasis on:

Shipping core audio-first workflows that feel instant and dependable
Building infrastructure patterns that can scale with adoption
Maintaining product velocity while improving reliability and quality

Outcome

MVP-to-scale execution with a lean team
Product stability improvements alongside feature delivery
Commons later joined Pulse; Mozilla acquired Pulse in December 2022

Features & Tech Stack

Built and scaled an audio-first communication platform for distributed teams from early MVP through scale. Created real-time audio and messaging workflows with infrastructure hardening for growth and reliability.

"Very professional, allowed us to move faster than our in-house team could manage with growing backlogs. Very satisfied with their work."
