About the founder
Peter Ndiku
Founder and software engineer at Mutual Labs, the company behind Steadline.
I build software that helps Kenyan businesses run on one set of records: sales, stock, purchases, money and books. My work sits between product engineering, financial systems, AI and the practical realities of running a business in Kenya.

Why Steadline
One system instead of five.
Many Kenyan businesses run sales in one place, stock in another, payments on a phone, and the books at month end. The numbers disagree because the records are separate.
Steadline is my answer to that. A sale moves stock, creates a receivable and posts to a double-entry ledger at the same time. M-Pesa, cash, bank and card payments reconcile against the same order. The reports come from the entries the business already made.
I designed and built the platform end to end: the multi-tenant data model, the accounting engine, the APIs, the integrations, deployment and the product interface.
Experience
Building, shipping and supporting real systems.
