Castle Raises 1 Million to Bring Automated Bitcoin Treasuries to Small Businesses
Managing a Bitcoin treasury isn’t just for corporate giants anymore. Thanks to a fresh 1 million in seed funding, Bitcoin-native startup Castle is gearing up to help small and medium-sized businesses (SMBs) bring their treasuries on-chain—without needing a finance team or in-house crypto expertise.
The raise, led by Stillmark with participation from prominent investors including The Bitcoin Opportunity Fund, marks a strong signal that Bitcoin-native financial tools are moving from big boards to Main Street.
What is Castle?
Castle is a simple yet powerful platform that allows SMBs to automate regular Bitcoin savings, functioning much like a “set-it-and-forget-it” treasury tool.
The product is designed to eliminate the complexity of managing crypto assets, offering features like:
- Recurring Bitcoin purchases
- Automated payroll savings in Bitcoin
- User-controlled custody
- Real-time treasury dashboards
By removing technical hurdles and simplifying access, Castle hopes to empower entrepreneurs and startups to hedge against inflation and diversify their corporate cash with sound money.
The Vision Behind Castle
According to Castle co-founder and CEO Ben Price, the idea was born from a clear need:
“Millions of small and medium-sized businesses want exposure to Bitcoin, but don’t have a CFO, a trading desk, or time to learn cold storage. We’re solving that with automated tools that are secure and easy to use.”
The company believes that Bitcoin isn’t just for high-net-worth investors or corporate giants like Strategy—it’s for anyone running a business who wants to future-proof their balance sheet.
Why This Matters for SMBs
Until now, most Bitcoin treasury strategies have been reserved for companies with dedicated financial teams. But inflation, devaluation, and global uncertainty have made Bitcoin savings increasingly attractive to everyday business owners.
Castle’s platform:
- Lets companies set recurring buys (like dollar-cost averaging)
- Offers custom treasury allocations
- Ensures non-custodial security, meaning businesses control their own keys
In other words, it bridges the gap between modern crypto strategy and real-world small business operations.
Who’s Backing Castle?
The 1 million seed round included investments from:
- Stillmark, a venture capital firm focused solely on the Bitcoin ecosystem
- The Bitcoin Opportunity Fund, led by early BTC advocates
- Several angel investors and syndicates committed to open-source finance
The capital will be used to expand the product, hire key team members, and build out integrations with accounting tools and fiat onramps.
Stillmark partner Alyse Killeen called Castle’s mission “pivotal” for making Bitcoin more accessible:
“Castle is delivering enterprise-grade tools to businesses that have been overlooked. They’re making Bitcoin treasury management as easy as setting up payroll.”
What’s Next?
Castle is currently onboarding early users in a closed beta and plans to open access to the public later this year. The team is also working on compliance features, multi-sig wallet options, and deeper integration with small business banking systems.
Their goal? Make Bitcoin treasury tools as normal for small businesses as checking their Stripe or QuickBooks dashboard.
Final Thoughts
This raise puts Castle on the map as a serious player in the Bitcoin-for-business space. By lowering the barrier to entry, they’re not just helping SMBs protect their wealth—they’re helping decentralize Bitcoin adoption at the business layer.
And with macro uncertainty pushing more people toward hard money, timing couldn’t be better.
