Software, web, cloud & AI built in Lagos
From idea to live system.
B-Jay Studio is the build division of B-Jay System, a Lagos technology company. It builds custom software, SaaS, web and mobile apps, cloud, data, and AI in weekly increments you can review, with the code, data, and accounts handed over in your name. Engagements start with paid discovery: a written scope, estimate, and plan before the big spend.

Read moreWhat you receive
- A written scope, estimate, and plan from paid discovery, before the big spend
- Software, SaaS, web, mobile, cloud, data, or AI, built in increments you can review
- Weekly demos, so progress is something you watch, not something you're promised
- Code, data, and accounts in your name, with documentation and a proper handover
For you, or not for you
A good fit
- Founders turning an idea into a product people can use
- Businesses whose 'system' is a spreadsheet held together by one brave staff member
- Teams that need senior engineering without hiring a whole department
Not the job for us
- A quick template site with no scope. Start smaller, with a brief.
- Shipping this week with no discovery. Fast is fine; blind is not.
How it works
Paid discovery
We scope the problem and give you a written plan and estimate.
Design & architect
We agree the data model, the architecture, and the milestones.
Build in increments
You review working software every week, not a surprise at the end.
Ship & hand over
We deploy, document, and hand you the keys. All of them.
Good to know
Will we own the code and data?
Yes. The source code, the data, and the accounts are yours, with documentation to match. If we ever part ways, you keep the system. That's the deal.
How do we start without betting the whole budget?
Paid discovery: a short, scoped piece of work that produces a written plan, an estimate, and the first increment. You decide what happens next, with real information instead of a pitch.
Do you work with clients outside Nigeria?
Yes. We're in Lagos and deliver remotely, with working hours that overlap the UK and the US East Coast. Your standup can happen while you're on your first coffee.
