What we build

Software made for your business

Most businesses run on notebooks, WhatsApp and a spreadsheet that only one person understands. We replace that with one place where the work lives, built around how you already do things.

One place for your daily work
Reports you can actually read
Different access for different staff
Works on a phone or a computer

Online shops

A shop your customers can buy from on their phone, pay for with M-Pesa, and track until it reaches them. Built for how people in Kenya actually shop.

Customers pay with M-Pesa
Stock updates as you sell
Delivery areas and charges
You see every order in one list

Money and record keeping

Invoices, payments, expenses and renewals in one place, so you always know what has been paid and what is still outstanding without digging through papers.

Invoices and receipts
What is paid and what is not
Several branches in one view
A record of who changed what

Websites

A website that loads fast on a cheap phone, says what your business does in plain words, and makes it easy for someone to call you or send a message.

Fast on any phone
Easy for customers to reach you
Found on Google
You can update it yourself

Our own products

Two things we built because our clients kept asking for them.

Our product

RenewWatch

Insurance, NTSA inspection, road licence, speed governor — they all run out on different days, and you usually find out at a roadblock. RenewWatch keeps every date in one register, starts reminding you sixty days early, and texts your customer in your own business name.

Reminders at 60, 30, 14, 7, 3 and 1 day, then the morning it expires
Your customer gets the text in your name, English or Kiswahili
Works offline, and on *384# for a phone with no internet

Who builds this

A small team in Nairobi

Synapse was started in 2024 to build the systems small businesses actually run on. We are small on purpose: the person who plans your system is the person who builds it and the person who picks up when you call.

What you can expect

Four promises that decide what we take on and how we hand it over.

We say what things will cost

You get the price and the date before we start, and we hold to them. If something changes, you hear it from us first, not on the invoice.

We build for here

Slow networks, shared phones, M-Pesa, staff who change often. These are not problems to work around later. We build for them from the first day.

We finish what we start

The job is not done when we send the files. It is done when your team is using it every day and the numbers it shows can be trusted.

Good software is quiet

The best system is the one nobody talks about. It opens fast, it does not lose work, and it stays out of the way of the person serving a customer.
