Two investors in Sign Protocol are worth understanding beyond the headline names.

Sequoia Capital led the 2022 seed. Sequoia applies traditional technology due diligence to crypto investments. They funded Sign before the sovereign infrastructure thesis was fully built, based on the core protocol and early TokenTable traction.

YZi Labs led the 2025 Series A. Beyond capital, YZi Labs brings access to the institutional networks across Asia and the Middle East that Sign's government partnership strategy depends on.

Total raised: over $30 million. Both investors reviewed the full technical and commercial picture before committing.

Institutional investors are wrong about specific projects regularly. But the quality of due diligence behind this cap table is meaningfully higher than most projects at this stage.
