Software-defined networking startup Arrcus raises $30M Series B led by Lightspeed Venture Partners, bringing its total raised to $49M

Context & Ripple Effects
Arrcus's raise lands mid-wave in a busy year for software-defined networking capital: Cato Networks pulled in $55M for SD-WAN just six months earlier — also led by Lightspeed Venture Partners — and Aryaka closed $50M Series F in May, bringing its total to $184M.
The pattern held beyond 2019: two years on, Versa Networks raised $84M to push its SASE console, folding network management and security together. Arrcus's $30M Series B, at a comparatively early $49M total, positions it inside that same investor thesis rather than against it.
First-order effects
- Arrcus gains runway to scale its software-defined networking platform while still pre-consolidation at $49M raised — far behind Aryaka's $184M total, so the money buys time more than leadership.
- Lightspeed now has two SDN bets from 2019 alone (Cato and Arrcus), concentrating its networking exposure in one category.
Second-order effects
- Cato, Aryaka, and Versa all sell into the same enterprise budget line that Arrcus is funded to attack, forcing each toward broader feature bundles or faster pricing moves to defend accounts.
- Later-stage players with deeper war chests can outspend Arrcus on go-to-market, pushing smaller SDN vendors toward consolidation or acquisition rather than head-to-head competition.
Third-order effects
- If the funding cadence holds, enterprise networking consolidates around subscription software consoles — Versa's SASE model suggests security and connectivity converge into single-vendor purchases, squeezing standalone box vendors out of new deals.
The trend: Venture capital is steadily shifting enterprise networking from proprietary hardware to software-defined platforms, with firms like Lightspeed serially backing multiple startups in the same category.
