In a market dominated by tech giants, Rubidium operates in the shadows, powering the voices we hear every day. With only 26 employees, they are betting everything on deep tech specialization rather than broad AI hype.

"They aren't selling a platform; they are selling the fundamental physics of synthetic speech."

The revenue-per-employee ratio sits at roughly $100,000. In the high-margin world of embedded software licensing, this is either a sign of a company in heavy R&D burn phase, or one that relies on a handful of massive enterprise contracts rather than volume sales. The absence of a public Trustpilot rating or clear product pricing suggests a sales-led motion, not a self-serve SaaS.

• Niche Focus: They own the 'text to speech engines' keyword (130 volume), signaling clear intent.
• Lean Operations: A 26-person team generating $2.6M implies high efficiency or a very long roadmap.
• Hidden Traffic: Low direct traffic (1,704 visits) suggests they are known by name in the industry, but not by the general public—a classic B2B trait.
