SkillBytes: from a WhatsApp MVP to 1.1M+ learners
SkillBytes proved its idea with an MVP that delivered bite-sized lessons on WhatsApp. As learners arrived, the original script began timing out during peak study hours.
We took over the engineering and rebuilt the backend so incoming WhatsApp messages are queued and acknowledged immediately, added Redis caching for active learner sessions, and set up a deployment pipeline. We also used learner drop-off data to improve onboarding.
The platform now serves 1.1M+ registered users and 100K+ monthly active users. The lesson for an EdTech MVP: prove learners come back first, then invest in scale.
