About Mahadi Hasan Sagor

Mahadi Hasan Sagor is the Co-Founder and Managing Director of Geeky Social, an agency widely credited as Bangladesh's first dedicated social media marketing company. He built it with a university classmate at a time when almost no local businesses treated social media as a serious marketing channel.

From Business Plans to a Blue Ocean

Sagor studied Finance for his BBA at the University of Dhaka and later completed an MBA in Marketing at Bangladesh University of Professionals. His entrepreneurial instincts showed up early, through business plan competitions he entered as a student alongside his eventual co-founder, Muhammad Saimum Hossain.

Those competitions were less about winning trophies and more about testing whether an idea could survive contact with a real market. By 2014, the two had settled on a plan built around a genuine gap: local brands had almost no organized presence on social media, and no agency was purely focused on fixing that.

Four Months Without a Client

Geeky Social launched as a two-person operation, and the first four months were rough. Sagor and his co-founder pitched fresh out of university, with no client roster and no case studies to point to.

Getting that first paying client took patience more than a clever pitch. Once it landed, the agency had proof that the model worked, and referrals started doing what cold outreach couldn't.

Building an Agency, Not Just a Client List

Under Sagor's leadership, Geeky Social grew from that first small engagement into a full social media marketing agency running campaigns for a wide range of brands across Bangladesh. The firm's pitch stayed consistent even as it scaled: deep, hands-on social strategy rather than generic ad placement.

That focus helped Geeky Social carve out a reputation distinct from larger, more generalist digital agencies that treated social media as one service among many rather than the core offering.

A Decade of Campaigns

More than ten years after founding the agency, Sagor has overseen campaigns worth more than BDT 1.5 crore for upwards of 100 brands. That track record has made Geeky Social one of the more established names in a marketing segment that barely existed in Bangladesh when the company started.

Sagor continues to lead the agency's strategy and client relationships directly, having stayed close to the operational side of the business rather than stepping back once it reached scale.
