“Paystack is aware of the allegations involving our Co-founder, Ezra Olubi,” the company told in a statement. “We take matters of this nature extremely seriously. Effective immediately, Ezra has been suspended from all duties and responsibilities pending the outcome of a formal investigation.”
“Out of respect for the individuals involved and to protect the integrity of the process, we will not be commenting further until the investigation is complete,” Paystack said.
Between 2009 and 2013, Olubi posted several tweets containing sexually explicit jokes about colleagues, described erections during meetings, referenced wanting to photograph a coworker’s thighs, and made comments involving minors and sexualised anime characters. One tweet from May 23, 2011, read: “Monday will be more fun with an ‘a’ in it. Touch a coworker today. Inappropriately.”
The tweets, posted years before he co-founded Paystack, resurfaced on Thursday and quickly spread across X. Their renewed circulation has intensified public scrutiny as the company investigates the allegation, fuelling broader discussion about workplace boundaries and expectations of behaviour from senior leaders in the ecosystem. Olubi has not publicly addressed the tweets or allegations of sexual misconduct. He also deactivated his X account on Wednesday, November 13, 2025.
Olubi’s tweets resurface in an ecosystem that has had to confront multiple incidents of workplace misconduct involving tech leaders in the past few years.
