Cloud security broker Netskope raises $100M Series E led by previous investors Lightspeed and Accel
As enterprises continue to move more of their computing to the cloud, and across an ever-expanding range of devices from computers to phones and tablets and more, hackers continue to find ways …
Context & Ripple Effects
This $100M Series E is the second act in what becomes a decade-long private funding arc for Netskope: two years after its $75M Iconiq-led round in 2015, the company is again turning to insiders, with Lightspeed and Accel leading. The bet pays off on paper within eighteen months, when Netskope crosses into unicorn territory with a $169M raise at a $1B+ valuation — also led by Lightspeed.
What makes the round notable is who is writing the checks: both leads are repeat investors doubling down rather than new capital validating the category, a structure that recurs through the company's later rounds and shapes how much ownership early backers retain by the time of the eventual IPO filing.
First-order effects
- Netskope gains $100M in primary capital from Lightspeed and Accel to fund its cloud access security broker expansion as enterprise workloads move off premises and onto phones and tablets alongside PCs.
- Lightspeed and Accel increase their exposure to Netskope ahead of the market, converting their earlier positions into larger stakes at pre-unicorn prices.
Second-order effects
- Insider-led financing sets the template for Netskope's subsequent rounds — Sequoia Global Equities' $340M in 2020 and ICONIQ Growth's $300M at a $7.5B valuation in 2021 — keeping control with existing backers as the valuation climbs roughly sevenfold from this round's terms.
- Competing cloud security vendors face a rival with an extended runway and no pressure to raise on outside terms, forcing them to seek comparably large war chests to keep pace on sales and engineering spend.
Third-order effects
- If the pattern holds, enterprise cloud security becomes a category where companies need nearly a decade of successive mega-rounds before testing public markets — Netskope's 2025 IPO ultimately prices shares at $15–$17, valuing it at up to $6.5B, below its 2021 private mark, illustrating the risk late private investors absorbed.
- Repeat-insider financing across the arc concentrates returns in a small set of firms — Lightspeed, Accel, ICONIQ — that carry a single portfolio company from Series E through IPO, reinforcing the trend of follow-on capital dominating growth-stage security deals.
The trend: Venture-backed cloud security companies are increasingly funded through successive insider-led mega-rounds spanning a decade before reaching public markets, with early backers compounding stakes at each step.
