Private company
Who owns DriveNets
One company in the researched set discloses a stake in DriveNets, none of it sized by anyone who discloses it. DriveNets is private, so no 13F reports it: a 13F covers exchange listed positions only. These figures exist because each holder disclosed the stake in its own filings.

DriveNets is an Israeli networking software company founded in 2015 by Ido Susan and Hillel Kobrinsky and based in Ra'anana. Its product, Network Cloud, applies the disaggregation model of hyperscale computing to carrier routing: instead of buying a proprietary chassis router, an operator runs DriveNets software over clusters of standard white box hardware built to the Distributed Disaggregated Chassis design, so that anything from a single box to hundreds of boxes presents to the network as one router. The software serves core, aggregation, edge and peering roles, and the company has extended it to AI networking fabrics for GPU clusters. AT&T has run its next generation core routers on Network Cloud since 2020, and by early 2023 the platform carried more than half of AT&T's North American core production traffic. DriveNets raised 262 million dollars in a Series C round led by D2 Investments in August 2022, with Bessemer Venture Partners, Pitango, D1 Capital, Atreides Management and Harel among its backers.

DriveNets files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from DriveNets Secures $262 Million in Series C Funding (PR Newswire, August 2022), DriveNets Network Cloud Now Carries More Than 52% of AT&T's Core Production Traffic (PR Newswire, 2023) and AT&T Deploys DriveNets Network Cloud in their next-gen core (PR Newswire, 2020). The ownership figures below come from the holders' filings instead, and are sourced row by row.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.
- AT&T Inc.. FY2025 10-K states AT&T holds a 16.6% interest in DriveNets but does not disclose a separate carrying value. DriveNets is grouped with Gigapower inside the single balance sheet line 'Investments in and Advances to Equity Affiliates' ($1,106 million at 31 Dec 2025, $1,130 million at 30 Jun 2026), which is not broken out by investee, so no shares or value figure is assigned to this row. source
What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of DriveNets where a holder stated one, and are missing where no holder did.
