Thom Jurek in his review for AllMusic stated, " Activate Infinity is a canny, wildly creative expression of the Bad Plus' collective persona; it's inspired, sophisticated, fresh, and a joy to encounter, time and again.

"[4] Writing for The Times Chris Pearson commented, "Ethan Iverson’s departure from the Bad Plus last year caused much anxiety.

The fears were unfounded, not only because Iverson’s replacement, Orrin Evans, is such a good fit, but also because the star soloist is in fact the drummer, Dave King.

"[6] A. D. Amorosi of JazzTimes noted "...the all-original Activate Infinity finds Evans mashing his own sinister soulfulness into swift Monk-like runs (“Avail”), playful Guaraldi-isms (“Thrift Store Jewelry”) and pastoral Bruce Hornsby-ish themes (“The Red Door”) without losing sight of his unique tone.

"[3] John Shand of The Sydney Morning Herald added, "Perhaps Evans emphasises the band's eccentricity slightly less than did Iverson, but in return he builds greater suppleness into the sound; a jazzy fluidity that re-contextualizes the back-beat music.
