About Sanzid Raihan
Raihan Ul Islam Sanzid, known professionally as Sanzid Raihan, is the Founder and CEO of Chorcha, an exam-preparation platform built for students navigating Bangladesh's SSC, HSC, university admission, and BCS competitive exams. He built the platform around a specific gap: students had plenty of study material, but few tools to actually practice and measure progress against real exam patterns.
Building for Bangladesh's Exam Culture
Sanzid founded Chorcha in December 2020, entering a market where exam preparation had traditionally meant physical guidebooks, coaching centers, and photocopied question banks rather than structured digital practice tools. Rather than digitizing existing textbooks, he built Chorcha around active practice: mock tests, previous-year question solving, timed challenges, and performance analytics.
That practice-first design meant students could see exactly where they stood against real exam-style questions, rather than passively consuming lecture content.
A Platform Built Around Practice, Not Just Content
Under Sanzid's leadership, Chorcha grew to include features like customizable study routines, progress notifications, and leaderboards, gamifying the intensely competitive culture around Bangladesh's national exams rather than working against it. The platform's database expanded to more than one million practice questions, covering the specific exam patterns students would actually face.
That scale of question data became one of Chorcha's core differentiators, giving students a depth of practice material that individual tutors or coaching centers couldn't easily replicate.
Reaching Half a Million Students
Chorcha has grown to serve more than 500,000 students and has surpassed one million app installs, a scale that reflects how widely Bangladeshi students turned to the platform once digital exam preparation started to catch on. That growth came almost entirely within the highly specific, exam-focused niche Sanzid built the company around rather than expanding into broader general education content.
Leading a Growing EdTech Platform
Sanzid continues to lead Chorcha's growth, maintaining the platform's focus on structured exam practice as its core value proposition even as competition in Bangladesh's edtech sector has intensified. That narrow, exam-specific focus has let Chorcha build deep credibility with students preparing for some of the most consequential tests in their academic careers.
