Quick Answer

No — Mike Krieger and Vicki Hollub are not together, and there is no evidence they have ever been romantically linked. Krieger, the Brazilian-American engineer who co-founded Instagram, has been married to artist and tech figure Kaitlyn Trigger since 2015. Hollub, who led Occidental Petroleum as its first female CEO from 2016 until her retirement in 2026, is married to independent oilman Glenn Vige. The pairing appears to be nothing more than two famous business names landing side by side in a search list.
