Paystack, a Nigerian payment startup, has suspended Ezra Olubi, its co-founder and chief technology officer, over allegations of workplace sexual misconduct.
A report by TechCabal said the fintech company has launched a formal investigation into the matter, after the allegation trended on social media on November 12.
Although Olubi’s X account has been deleted, social media trend showed his tweets were posted before he co-founded Paystack.
The tweets, shared by Olubi between 2009 and 2013 included sexually explicit jokes about colleagues, and mentions of experiencing erections during meetings.

They also showed comments about wanting to photograph a coworker’s thighs, and remarks that referenced minors, bestiality, and sexualised anime characters.
“Paystack is aware of the allegations involving our Co-founder, Ezra Olubi,” the firm told TechCabal.
“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 it has established a “fair, transparent, and structured” review process to conduct a thorough investigation.
This, the payment firm said, aligns with its internal policies.
“This process is guided by our policies, our values, and our commitment to maintaining a safe and respectful environment for all employees,” the firm added.
