Steel Atlas Zeno Pre Series C SPV a Series of CGF2021 LLC

The presence of two named GPs — an LLC (Sydecar, a fund administration platform) and an individual (Brett Sagan) — combined with zero prior EDGAR filings from this manager, indicates this is either a first-time fund manager using a third-party operator for compliance, or a known investor operating through a newly formalized entity; the reliance on Sydecar as a co-GP suggests either nascent fund operations or a preference for outsourced fund governance.

A May 2026 filing for a pre-Series C vehicle aligns with mid-market venture rounds typically closing 18–24 months after Series B, and the exemption 06b restriction to pre-existing relationships signals the GP is moving capital quickly among existing LPs or portfolio company shareholders rather than conducting a broad market raise—consistent with a conviction follow-on after earlier vintage performance materialization.

Verify whether Brett Sagan has prior fund management or investment experience outside EDGAR filings (via LinkedIn, PitchBook, or fund databases), and confirm whether Sydecar's role is administrative only or includes governance rights; also check if CGF2021 LLC has other active SPVs or vintages filed under different states, as the absence of prior EDGAR history does not rule out concurrent fundraising activity outside SEC view.
