questions?
When does the next cohort start?
Our next intake starts on 11 January 2027: Foundation on Monday 11 January and Professional on Tuesday 12 January 2027. The 9 November 2026 intake has already started. Apply for the January intake and we confirm your seat on WhatsApp. You only pay once it's confirmed.
Do I need coding experience?
No for Foundation. For Professional, some prior programming experience is recommended so you can keep up with the pace and dual-platform workload.
Do I need to pay in full immediately?
No. Applying is free, and fees are paid monthly over the 3 months of the course: KES 15,000 a month for Foundation or KES 25,000 a month for Professional. The first month reserves your seat. You can also pay in full up front.
Can a parent, guardian or employer pay my fees?
Yes. They can pay each month by M-Pesa Paybill using your name as the account, and with your agreement we send them a short monthly progress update. Employers can ask for an invoice. How sponsoring works.
How do I pay?
By M-Pesa: Lipa na M-PESA, Pay Bill, business number 880100 (NCBA Bank), account number 1009174147. M-Pesa shows the recipient as NCBA BANK, which is Bridgetree's bank.

What do I need to join?
A laptop and a stable internet connection. Classes are live and online, so you can join from anywhere. To publish your capstone app you'll also need your own developer accounts: Google Play charges a one-time USD 25 fee, and Professional students also need Apple's Developer Program at USD 99 a year. These go directly to Google and Apple, not to us.
Will this help with actual job readiness?
Yes. Portfolio projects, store publishing support, CV and LinkedIn optimization, mock interviews and practical career guidance, plus weekly DSA drills for technical interviews.

Yes. Book 1-on-1 tutoring at KES 2,500 per session. See tutoring details.
