North Block Capital

What North Block Capital does

North Block Capital appears in firmographic records as a London-based private entity classified as Blockchain Asset Managers, founded in 2017, with 11-50 employees and Simon Wajcenberg listed as a founding partner. The operational substance of the supplied source material, however, describes Sunwin, a multi-platform online entertainment and gaming platform operating since 2019 from Ho Chi Minh City, Vietnam, and serving Asian and Southeast Asian consumer markets. There is a clear discrepancy between the corporate identity in the firmographic header and the operational content of the source material; this analysis describes the operational entity documented in the sources.

Sunwin is a consumer-facing online gaming platform offering four core product pillars: Card Games (traditional Vietnamese card games with 3D interface and real-time random dealing), Slot Games (with cinematic 4K graphics and progressive jackpots reaching billions of VND weekly), Casino (live-dealer style games including baccarat, roulette, dragon tiger, and Sicbo VIP), and Lottery (regional draws plus fast-draw formats with a stated 1:99 payout ratio). The platform is accessible across Desktop, Mobile App (Android APK and iOS), and Web H5.

The underlying technology stack includes a proprietary certified Random Number Generator, SSL 256-bit encryption layered with next-generation firewall protection (the platform claims to block over 1.2 million unauthorized access attempts per month), and an automated payment infrastructure integrated with 35+ major Vietnamese banks and international e-wallets, supporting average withdrawal processing of 90-180 seconds and a stated 96% user satisfaction rate on transactions. The platform holds an Isle of Man Gambling Supervision Commission license and a PAGCOR license, with an average Return to Player of 97.5% across a 400+ title catalog refreshed quarterly.

The business model is B2C with horizontal segmentation targeting individual gaming enthusiasts in Asia and Southeast Asia. Revenue is generated through player wagering activity net of payouts, supplemented by a heavy promotional layer including first-deposit bonuses up to 300% (capped at 15.8M VND), daily check-in rewards of 88,000 VND, cashback of 1.5%-5%, and reload bonuses of 20%-50%. Distribution is direct-to-consumer via web, Android APK direct download, and iOS enterprise-trusted distribution through Safari, with marketing via Telegram, SEO-optimized content, and referral code programs. Customer support is delivered 24/7 across Live Chat, Telegram, and Hotline with a stated first-response time under 30 seconds.
