Janover Inc. (JNVR) just pulled off one of the most jaw-dropping stock moves of 2025—an 842% surge in a single day—by doing something bold: pivoting completely into crypto and Solana.

The once-sleepy real estate tech firm is now the DeFi Development Corporation—and its stock price exploded on the news.

From Fintech Niche to Full Crypto Makeover

On April 7, Janover dropped the bombshell: a crew of ex-Kraken executives took over the company, raised $42 million, and rebranded it as a Solana-first blockchain company focused on validator infrastructure and DeFi apps.

The result? Janover’s stock rocketed from $10 to $48.47, closing the day at $40.25—an 8x gain that turned heads across finance and crypto Twitter alike.

A Real Estate Software Company No More

Founded in 2018, Janover originally helped real estate borrowers connect with lenders through an AI-powered SaaS platform. It IPO’d in July 2023 at $4 per share but remained largely under the radar—until now.

Its market cap hovered below $5M just days ago.

Crypto Insiders Take the Wheel

The takeover involved 728K+ common shares and 10K preferred shares sold to a crypto-native team backed by Pantera Capital, Kraken Ventures, and Arrington Capital.

Key terms:

• Convertible notes with 2.5% interest, convertible at $4.81 if the company hits a $100M cap
  
• Warrants priced at $120–$150 per $1,000—giving early backers some serious upside potential
  

Why Solana? Think Yield + Ecosystem Integration

Rather than stockpiling BTC like MicroStrategy, Janover’s betting on Solana (SOL)—a proof-of-stake chain that pays 5–7% staking rewards and lets companies run validators for passive yield.

The game plan includes:

• Acquiring SOL
  
• Launching Solana validators
  
• Building crypto-native tools that fuse real estate + DeFi
  

It’s not just a treasury shift—it’s a technical and strategic integration with one of the most active chains in crypto.

Meet the New Crypto-Heavy C-Suite

• Joseph Onorati (former Kraken CSO) – Now Janover’s Chairman & CEO
  
• Parker White (Kraken’s ex-Engineering Director) – CIO & COO
  
• Marco Santori (former Kraken CLO) – Compliance lead on the board
  

Founder Blake Janover and CFO Bruce Rosenbloom are still involved, running the original SaaS arm.

Why It Matters: A New Corporate Crypto Model

Janover isn’t the first company to embrace crypto—but it’s the first public U.S. firm to use Solana (not Bitcoin) as its primary reserve asset.

That makes it a blueprint for the next wave of Web3-aligned businesses, especially those too small to play the BTC game.

Other examples:

• Metaplanet (Japan)
  
• Sol Strategies (Canada)
  
• Even GameStop flirted with tokenization
  

Solana Pumped Too

SOL jumped 11%, from $96.50 to $112.30, following Janover’s news. That kind of momentum shows how one company’s pivot can ripple through the whole ecosystem.

Is This the Future of Public Companies?

Janover is now part of a new class of hybrid companies: cash-flow + crypto-native yield. If this model works, expect more under-the-radar firms to go crypto-native—with Solana, staking, and validator rewards leading the charge.

One thing’s for sure: Janover just made itself the one to watch in 2025.
