Our products

Three products, one standard of craft

The games Nigeria grew up on, safer payments, and confidential communication. Each one carries the same engineering culture, design bar and long-term ambition.

NaijaGamez

Games

Classic games, anywhere

The games Nigerians already know how to play, on the phone in your pocket. Whot, Ludo, Draughts and Ayo, plus a party pack of Charades, Mafia, Would You Rather, Two Truths and a Lie and quizzes.

  • Board and card classics plus party games
  • Online, over local Wi-Fi, or offline vs AI
  • Free to play, with tournaments and leaderboards

Sendsaii

Payments

Safer money for the internet

Multi-currency wallets and disposable one-time virtual cards. Every online purchase gets a fresh card that's used once and then dies — so a leaked checkout never becomes a drained account.

  • One-time cards, revealed once behind a PIN
  • NGN, USD, GBP, EUR and more, side by side
  • Team cards with limits for businesses

Institutions

Secure institutional messaging

Provably confidential communication with the governance regulators demand. Boards, M&A and regulatory responses get confidentiality even the operator can't break — without giving up membership control or audit trails.

  • Operator provably unable to read content
  • Membership control and audit trails
  • Audited crypto core, sovereign deployment
The company

A Nigerian software company with a builder's mindset

Ossai Space Limited exists to build software products that solve real problems. As the company behind BlackBoxNg, Sendsaii and NaijaGamez, we provide the shared foundation — engineering standards, governance and long-term thinking — that lets each product team focus on its users.

We are registered with the Corporate Affairs Commission of Nigeria and operate with a simple belief: world-class software can, and should, be built from here.

How we build

The principles behind every product

Three habits, applied the same way whether we are shipping encryption for a board or a Ludo board.

01

Product first

We start with a real problem and a real user, then engineer backwards from the experience they deserve.

02

Engineering discipline

Security, reliability and maintainability are non-negotiable across every product we ship.

03

Built to last

We think in decades, not demo days — building durable products rather than chasing trends.
