What ZeroStack does

ZeroStack Corp. (Nasdaq: ZSTK), formerly Flora Growth Corp., is a publicly traded asset management company that pivoted from cannabis consumer products to AI-focused digital asset management in 2025-2026. Its core strategy centers on accumulating and staking 0G tokens — the native asset of the 0G decentralized AI operating system — holding approximately 21% of total token supply (~142M+ tokens valued at ~$107M as of March 2026) and generating recurring yield through proof-of-stake validation at approximately 22% APY (~$50,000/day). The company is debt-free following the elimination of a convertible note from 0G Labs in March 2026 and has secured institutional-grade custody via BitGo. Beyond the digital asset treasury, ZeroStack operates Phatebo GmbH, a wholly-owned German pharmaceutical distribution subsidiary with over ten years of operating history that generated $35.9M in 2024 revenue at 6.1% gross margins, serving European healthcare markets including Germany and Austria with access to 40,000+ pharmacies.

The business model combines two distinct revenue streams: (1) protocol-level staking rewards from 0G token holdings, which generated ~$2.2M in ~45 days of staking activity, and (2) B2B pharmaceutical distribution orders, with disclosed orders exceeding $21M in 2026. ZeroStack distributes its investment product through public equity markets (Nasdaq: ZSTK) accessible to both institutional and retail investors via standard brokerage accounts, while pharmaceutical distribution is fulfilled through direct enterprise sales via Phatebo's established logistics network. The company's go-to-market leverages Nasdaq listing visibility, CEO media presence across Bloomberg, Forbes, CoinDesk, and Business Insider, and direct investor relations communications. Leadership includes CEO Daniel Reis-Faria (MIT Entrepreneurship, former founder of OARO aviation cybersecurity), Executive Chairman Michael Heinrich (also co-founder of 0G Labs, Forbes 40 Under 40, ex-Microsoft/SAP Labs/Bain/Bridgewater), and CFO Dany Vaiman (CPA, formerly at Franchise Global Health and Torex Gold Resources). ZeroStack is headquartered in Toronto, Canada with plans to redomicile to Texas, USA, subject to shareholder approval.

Revenue model

1. Staking Rewards (0G Tokens): ZeroStack earns 0G tokens as staking rewards through its participation in the 0G network's staking protocol, which compensates token holders for supporting network operations and security. As of March 2026, the company had earned 3.2 million 0G tokens at an approximately 22% APY, valued at approximately $2.2 million (~$50,000/day). The company holds a strategic position of approximately 21% of total 0G token supply.
2. Pharmaceutical Distribution (Phatebo GmbH): ZeroStack operates a global pharmaceutical distribution business through its wholly owned German subsidiary Phatebo GmbH, which has operated as a pharmaceutical distributor in Europe for over ten years. Phatebo generated $35.9 million in revenue in 2024 with 6.1% gross margins, serving European healthcare markets including Germany.
3. Capital Appreciation on 0G Token Holdings: As a treasury strategy, ZeroStack holds approximately 21% of total 0G token supply (~142 million tokens as of March 2026, valued at ~$107M). Long-term token appreciation represents a key component of the asset management strategy, combined with recurring staking rewards.
4. Pharmaceutical Distribution Orders: Phatebo secures purchase orders from pharmaceutical companies for distribution of pharmaceutical products in Germany. Orders include up to approximately US$14.7 million (EUR 12.9 million) in pharmaceutical inventory from two companies, and a $6.5 million order from a major pharmaceutical company, fulfilled through Phatebo's established logistics network.

Broad incumbents

• MicroStrategy: Pioneered the corporate digital asset treasury model with its Bitcoin holdings. Established the public-market template that ZeroStack is now replicating for AI-protocol tokens (0G), making it the closest established incumbent analog at much larger scale.
• Coinbase Global: Largest US crypto exchange providing custody, staking, and trading services. As ZeroStack's staking partner-adjacent ecosystem provider and broader crypto infrastructure benchmark, Coinbase serves as the incumbent reference for public-market crypto adoption.
• Cencora: One of the Big 3 US pharmaceutical distributors. Provides the closest large-scale operating analog to ZeroStack's Phatebo GmbH subsidiary, which generates $35.9M in revenue distributing pharmaceuticals across Europe.

Emerging players

• Bit Digital: Former crypto mining company that pivoted into an Ethereum-focused digital asset treasury. Represents a comparable precedent of a public company transforming its business model around a crypto-native strategy.
• SharpLink Gaming: Ethereum-focused digital asset treasury company using a public-equity vehicle to accumulate a major crypto position. Comparable to ZeroStack's strategy of substituting corporate treasury composition with strategic tokens (ETH vs. 0G).
• Upexi Inc. Solana treasury company pursuing an aggressive public-market token accumulation strategy. Operates a smaller-scale but methodologically similar DAT model relevant to ZeroStack's approach to 0G.

Direct peers

• DeFi Development Corp. Public Solana treasury company that led ZeroStack's $401M PIPE with a $22.88M strategic investment. Operates a directly comparable digital asset treasury model, accumulating and compounding a native crypto asset on behalf of public-market shareholders.
• Janover Inc. Solana-focused digital asset treasury company. ZeroStack's CEO Daniel Reis-Faria originated the deal that connected Janover with DeFi Development Corp. to create the first Solana treasury vehicle, making it a tightly linked peer in the crypto-treasury ecosystem.
