Bain Capital Ventures Closes $1.6B Fund XI — Not Bain Capital’s $225B AUM

Bain Capital Ventures said on September 16, 2026 that Fund XI is $1.6 billion of total capital for early- and growth-stage technology. Bloomberg put the predecessor at $1.4 billion. Bain Capital’s about $225 billion AUM is the parent platform, not this vehicle.

Bain Capital Ventures Closes $1.6B Fund XI — Not Bain Capital’s $225B AUM

Bain Capital Ventures said on September 16, 2026 that it has raised $1.6 billion of total capital for Fund XI, to make early- and growth-stage investments in technology companies. The number that will get copied wrong is about $225 billion — that is Bain Capital parent AUM, not this vehicle. Bloomberg put the predecessor at $1.4 billion and said Fund XI is slightly larger; BCV’s own post did not name the prior size. LP names were not disclosed. Last verified September 17, 2026. Sources: BCV, Bloomberg.

A $1.6 billion multi-stage venture close is real dry powder. It is not a $225 billion “Bain” headline and it is not a16z Growth’s $8.5 billion scaling book.

Five-minute decision

If you need…Verdict
What happenedFund closed. Fund XI $1.6B total capital. Sep 16, 2026.
MandateEarly- and growth-stage “outlier technology businesses” (BCV). Bloomberg: infrastructure, physical world, security, services.
$225BParent AUM (BCV). Not Fund XI.
Prior fund$1.4B is Bloomberg, not the BCV post.
LPs / first vs finalNot disclosed.
DirectoryYes — /fund/bain-capital-ventures.

Investigate further when: you want a Bain-platform multi-stage check next to names we already cover (Redis lineage, Etched, Rillet).

Wait or pass when: you add Fund XI to Bain Capital PE AUM, or treat $1.6B as a first close of a larger target the firm did not state.

Do not add them. They answer different founder questions. Cherubic VI is a $68.88 million solo-GP book — smaller still.

Named BCV overlap already on this site includes Etched and Rillet. This close is not a new round for those companies.

What remains undisclosed

No LP letter. No first-versus-final split. No check-size grid. No BCV-only AUM besides this $1.6 billion print. Predecessor $1.4 billion is Bloomberg. “Post-AGI” is editorial framing in the essay, not a portfolio rule you can diligence from the post.
