Is "M-Pesa recurring billing for African SaaS" a viable startup idea in 2026?

STK-push subscription billing that actually retains customers. The wedge: Drop-in recurring layer + smart retry + dunning WhatsApp.. Difficulty is rated starter with a workflow moat, so treat it as a 4–8 week ship-and-see build.

Who is the buyer for this idea?

Founder of an African SaaS charging KES 500-50k/mo. Reach them through devcongress kenya and african founder podcasts. Skip broad SEO on day 1 — start where your first 20 customers already hang out.

How would you monetize it?

1-2% + $0.10/txn. Pricing is the most under-thought step for these buyers, so anchor to the outcome you replace, not the tool you resemble.

M-Pesa Daraja API v2 finally supports better recurring hooks. That's the underlying shift — if it fades, so does the wedge.

What tech stack would you use?

Suggested stack: Next.js, Supabase, and M-Pesa Daraja API. You can build the v1 in weeks on this stack; the moat is workflow depth, not framework choice.

Who are the incumbents I'd be competing with?
