Tripling course completion for a cohort learning company

A cohort-based learning platform with live sessions, assignments, and accountability loops that took course completion from 23% to 68% and scaled to 5,000 concurrent learners.

The challenge

Client: Professional training provider
Services: SaaS Development, Web Development, UI/UX Design
Timeline: 12 weeks to launch

The company sold serious professional courses, but ran them on a patchwork of Zoom links, Google Docs, and a self-paced video library. Learners started strong, drifted by week three, and quietly disappeared. Completion sat at 23%, and refund requests tracked it.

The founders knew the fix was structure: cohorts, deadlines, visible progress, peers who notice when you're gone. The patchwork couldn't deliver any of it.

What we did

The approach, decision by decision

01
Built the accountability loop into the product
Cohort dashboards show streaks, submitted assignments, and who's fallen behind. Instructors see the drift in week two, while a nudge still works.
02
Made live sessions the spine, not an extra
Scheduling, recordings, attendance, and follow-up assignments hang off each session, so missing one has a visible cost and an obvious recovery path.
03
Engineered for launch-day spikes
Cohort launches concentrate thousands of learners into the same hour. Load-tested to 3x the biggest cohort before the first one went live.

The results

Completion rose from 23% to 68% across the first six cohorts on the platform.
5,000 concurrent learners at peak with p95 page loads under 400ms.
Refund requests fell by more than half as completion climbed.
NPS of 61, and the recordings library became a second product line.
