TopK

Funding & Investors

$5.5M raised

As of October 20, 2026, TopK's funding: A $5.5M seed closed July 1, 2025, is the only round on record. That is enough runway to build and sell, but buyers committing to TopK as infrastructure should factor in that the company has not yet demonstrated a Series A.
