About

Your team runs on email. Your processes shouldn't. Lumen is for process owners who still run work in email. Every request gets a named owner, an SLA, and live cycle time, so work does not stall in inboxes. Built for ops teams at 40–200 person companies. When ownership, SLAs, and data live in scattered emails, work turns into delays, rework, and compliance risk. Lumen gives process owners one live, multilingual place to run a process: who owns each step, whether it is inside SLA, and how long it actually takes. Early access; we set up your first process free. Pricing: Starter $29/user/month, Professional $79/user/month, Enterprise custom.

About

Siperb pairs a modern WebRTC softphone (Web, Windows, macOS, Linux, Android, iOS) with a hosted WebRTC-to-SIP proxy, so teams on Asterisk or FreeSWITCH get browser and mobile calling without replacing their existing PBX. Features include call recording (audio & video), blind/attended transfer, 3-way conferencing, and end-to-end encrypted media. The client UI is open source (AGPL-3.0); the hosted proxy and mobile apps are proprietary. Free Personal tier; Business (£2/user/month) and Business Pro (£5/user/month) add storage, custom integrations, and upcoming AI features.
