THE BUSINESS
Get to know Tanium.
Tanium provides endpoint-management and security software for large IT environments. Its platform combines real-time asset visibility, patching, configuration control and threat-response workflows.
Tanium's own releases support six exact disclosed financings totaling $712M in this source-backed subset, but not the imported Series J/I/H/G/F/E/D/C/B labels. The January 2021 $150M sale was completed common stock to Ontario Teachers; a separate 2020 Form D reports $150,499,974 of equity securities sold in an offering, not net issuer proceeds or a completed $200M target. Original 2009, 2010 and 2011 SEC notices add three earlier equity-offering observations, not authenticated net new capital. Amendments replace earlier sold-to-date observations within the same offering; targets and unsold balances are not additional proceeds. Related-person listings are not subscriber lists. Salesforce confirms an earlier June 2020 strategic financing but not its amount. The reported May 2018 $175M TPG transaction included employee-share purchases, so no exact new-company-capital component is inferred. The 2007 $2M claim remains database-only. Issuer release dates, filing publication dates, Form D first-sale dates and reported transaction dates are distinct; this is not a complete legal financing register or current cap table. SEC publication does not mean the filing was verified by the SEC. The old latest-round article's Series J label is withheld from this company ledger pending editorial review.

Common-stock financing

TPG investment including employee-share purchases
TPG Growth (lead)
Reuters-syndicated reporting says TPG bought shares from early employees as part of a $175M investment. The exact issuer-primary versus holder-secondary split is not established; no $175M new issuer capital is counted. May 16 is report date, not proved legal settlement.
Issuer says $100M was raised by issuing common stock and some proceeds repurchased founder shares; use of proceeds for holder liquidity is not another financing round. Its release does not call this Series E.

These notices are one offering, not two rounds or additive proceeds. April 30 is the first-sale day, not proof that the full amount sold that day; a zero unsold balance is not an independently authenticated bank receipt or legal close.
