The customer

Two engineers, a designer, a founder — and the need to ship next week.

Kenyan startups can't afford to lose a quarter to carrier integration. Sozuri pre-built the SMS, USSD, OTP and M-Pesa rails so your team can spend Day 1 on the product, not on KYC paperwork.

Why startups pick Sozuri early

The five things you don't have to build

Sender-ID approvals

We hold the carrier relationships. You inherit branded sender IDs without negotiating with Safaricom yourself.

Daraja orchestration

Bring your M-Pesa credentials; we do the STK Push, the polling, the webhook reconciliation.

USSD platform

Drag-build menus — no need to peer with carriers yourself. Skip 4+ months of bizdev.

AI agents on tap

Upload your docs, pick the model, ship. Save your model-ops budget for the actual product.

WhatsApp Business

Verified-business onboarding done by us. You write the templates, we deal with Meta.

Webhook + audit infra

Signed callbacks, idempotent message IDs, audit-grade logs. Investor-question-ready from Day 1.

What changes

Founders' time, reallocated

10 min

To first OTP sent

From signup to a verification code on your own phone. Onboarding designed for engineers, not bizdev meetings.

4–6 months

Of carrier integration skipped

That's how long building this in-house typically takes. We already finished; you inherit the result.

No floor

Minimum spend

Pay-as-you-go from the first SMS. Free credits cover the first 100. Scale tiers kick in automatically as you grow.

“The carrier paperwork would have eaten three months. We picked Sozuri on Day 4 of the company and were sending our first OTP that afternoon.”

Your move

Skip the bizdev sprint.

Wire the API today; pay only what you use; flip on every new channel as the product demands it. Sozuri is the boring-but-essential infrastructure layer so you can build the interesting part.
