Best OSS & BSS Companies in United States
The 434 best OSS & BSS companies in United States in 2026, ranked by funding and momentum. Funding, investors, founders, valuation, tech stack and live signals. Top: Plume.
Ranking the top OSS & BSS companies across the United States by disclosed equity funding, this directory tracks 434 firms and $4.3B in total capital — and the revenue picture behind those numbers is worth sitting with. Six validated filers posted a combined ~$402M in revenue, with a median of ~$36M. Comverse Technology pulled $202M at the top, Tekelec followed at $108M, and Cambium Networks Corp filed $43M. Median YoY growth sits at -16%, which tells you something real about where legacy OSS & BSS infrastructure spending is right now. So what's actually holding margins up? Tekelec earned $15M net, roughly 6x the sector median, while Pareteum Corp and Wireless Telecom Group each cleared 3-4x. Earned revenue at that scale, in a contracting environment, is the signal worth tracking.
Funding leadership looks different from the revenue stack. Connectbase leads at $54M raised, Lightyear follows at $48M, and Gigs pulled $20M, with Accel and Bessemer Venture Partners among the most active backers. Luna Innovations is the one filer bucking the revenue trend, posting 11% YoY growth on $29M. I'd watch that outlier closely. As one recent analysis of OSS/BSS deployment patterns notes, operators are pressing hard on integration gaps that smaller specialists can fill. The single unicorn in this directory suggests the exit ceiling is real, but so is the floor for durable, cash-generating players.
