NS1, which provides DNS and application traffic management services, raises $33M Series C led by Dell Technologies Capital, bringing its total raised to $85M+
NS1, a New York-based company developing web and app traffic management solutions for enterprises, today revealed …
Context & Ripple Effects
This round was an early marker in NS1's run from enterprise DNS upstart to acquired platform: after this $33M Series C led by Dell Technologies Capital pushed total funding past $85M, the company went on to raise a $40M Series D less than a year later, before IBM acquired it in March 2023.
The aftermath matters as much as the raise itself — NS1's open-source tooling was strong enough that it spun out NetBox Labs, which immediately landed its own $20M Series A, showing how much durable value the venture funding built inside the company.
First-order effects
- NS1 gains an extended runway and a strategic backer in Dell Technologies Capital, tying its enterprise DNS and traffic-management push to Dell's infrastructure customer base.
- Enterprise buyers evaluating application traffic management get a better-capitalized independent alternative to incumbent DNS providers at exactly the moment multi-cloud routing demand is rising.
Second-order effects
- Capital keeps flowing into the DNS layer: DNSFilter's $30M Series A two years later shows investors treating DNS-adjacent security and filtering as a standalone category worth funding, forcing NS1-style players to differentiate between performance routing and threat protection.
- Software-based networking broadly becomes the funding magnet — DriveNets' $110M stealth exit and subsequent $208M Series B at a $1B+ valuation mirror the same bet that routing and traffic control are moving off proprietary hardware.
Third-order effects
- The pattern NS1 followed — repeated venture rounds, then absorption into a large platform acquirer with the open-source assets carved back out as startups — points to enterprise network software consolidating under big vendors while continuously reseeding the startup layer.
- If consolidation holds, enterprises face fewer independent traffic-management vendors over time, shifting leverage toward platform bundles like those Versa Networks is assembling by unifying networking and security in one console.
The trend: Enterprise networking software is cycling through heavy venture funding into consolidation by major platform vendors, with open-source spinouts keeping the independent layer alive.
