Nexus International, led by founder Gurhan Kiziloz, is allocating $200 million to expand Spartans.com, a casino and sports-betting platform designed to strengthen the group’s position in global online gaming.
The funding marks Nexus International’s most significant move yet into the iGaming space and follows the success of Megaposta, its high-performing betting brand in Brazil.
Building for modern players
Spartans.com brings casino games, live-dealer tables and sports betting together under a single, mobile-first platform. It supports both traditional payment methods and cryptocurrencies such as Bitcoin, Ethereum and Tether, with crypto withdrawals typically processed within minutes: a marked difference from the multi-day delays common across much of the sector.
The platform features over 5,000 games and a player dashboard giving users complete visibility over deposits, wagers and withdrawals. Development is underway on a series of new tools intended to make gameplay more social, interactive and personalised - features the company believes will distinguish Spartans.com from established competitors.
A self-funded path
Since its founding, Nexus International has grown without external investors. Kiziloz has maintained that independence to keep strategic decisions internal and to reinvest profits directly into technology and expansion rather than short-term marketing.
That approach helped Megaposta establish itself as one of Brazil’s fastest-growing betting platforms, built on operational consistency rather than aggressive promotion. Spartans.com is following a similar playbook — scaling methodically and focusing on long-term infrastructure before visibility.
Competing with the giants
Spartans.com enters a market dominated by major operators such as Flutter Entertainment, the parent company of FanDuel and Paddy Power, and Entain, which owns Ladbrokes and bwin. Both hold extensive market share and long-standing relationships across sport and media.
Rather than attempting to outspend larger competitors, Spartans.com is focusing on a streamlined user experience, fast payment systems, and cross-currency compatibility. Analysts say this combination could make it appealing to a younger audience that values speed and flexibility over traditional branding.
Quiet growth, firm direction
Nexus International reported strong third-quarter results in 2025, crediting much of its momentum to Spartans.com’s early performance. The $200 million allocation will fund further product development, recruitment and feature rollouts through 2026.
Kiziloz has kept a low public profile despite Nexus’s growing influence, preferring to emphasise structure and sustainability over public statements. The strategy remains consistent: build quietly, grow steadily, and let performance define visibility.
In a sector driven by rapid spending and high-volume marketing, Spartans.com’s disciplined growth may prove to be its biggest advantage: a reminder that sometimes the quietest operators make the strongest impact.
