Smart Block Island

Smart Block Island is a software firm from Houston, Texas, not the island off Rhode Island. Founded in 2022, it turns who owns a private business into digital tokens. A firm makes one token with a fixed supply. It hands out shares of it to founders, staff, advisors and backers, and smart contracts run the vesting. The result is a cap table that keeps itself up to date. Each change is logged on a blockchain, and each grant is tied to a signed legal agreement.

It is built for small and mid-sized firms that track equity in spreadsheets and paper files. As of October 2026 the main Build plan costs $199 a month. A larger Scale plan with accounting tools is still marked "coming soon".

How Smart Block Island tokenizes a business

It starts with one custom token. The firm sets the total supply, then hands it out. Per the homepage, "each allocation connects to a stakeholder wallet and a legal agreement", and "every token links directly to its signed agreement". The token is a record of who owns what under that agreement. It is not a coin you can trade.

Smart contracts then do the jobs that are often done by hand: vesting, cliffs, payouts and votes. Each change to the cap table is logged on-chain. That gives a trail of past changes that no one can quietly edit.

Key papers, such as operating agreements, term sheets and board minutes, are kept on IPFS, a shared file network. Each holder gets a dashboard. It shows their token balance, their share of the firm, how much has vested and an "estimated stake value", based on their share and a value for the business.

Smart Block Island cap table and vesting features

The cap table is the centre of the product. It updates when tokens are issued, vested or moved, so the company doesn't rebuild it from documents each time an investor asks for a data room.

The Build plan, per the pricing page, includes:

• a live cap table and tokenized ownership management;
• vesting schedule setup and automated distributions to token holders;
• a business valuation simulator, which the homepage says links to "professional valuation services";
• what the page calls "private blockchain record-keeping";
• 50 GB of IPFS document storage;
• individual holder dashboards, team management and priority support.

Smart Block Island pricing: Build and Scale plans

Build costs $199 a month, with 10% off for annual billing. The site's main button reads "Get Started Free", but the pricing page doesn't spell out what the free entry covers. There are no contracts: you can cancel at any time, and the company says data stays exportable after you leave.

Scale is listed at $699 a month and marked "coming soon". It adds accounting tools that are still being built. These include a live ledger that logs each payment as it happens, payroll, voting tools, API access, a Stripe link and a named account manager.

The company has pitched accounting before. Its Circle Alliance listing, last updated in June 2025, calls it a "blockchain-powered financial platform" meant to replace QuickBooks. That listing also names stablecoin spending, branded debit cards and payroll. Today, ownership tokens lead the product, and the accounting tools sit in the Scale plan, which hasn't launched.

Smart Block Island partner program for CPAs and attorneys

The partner program is aimed at CPAs, business attorneys and fractional CFOs who manage equity for several clients. Partners onboard clients with a signup link, track them from a partner dashboard, and earn monthly recurring revenue on every client they bring in. The page doesn't publish the revenue share.

This makes advisors a sales channel as well as users. The company's blog, which posted five articles between February and March 2026, leans on the same theme, with titles such as "Why Ownership Questions Always Land on the CPA".

The Contribution Marketplace: equity for work

The Contribution Marketplace is a separate app that links early-stage companies with people willing to work for a stake. It calls itself "not a job board and not a fund", but "a ledger of teams offering real ownership for the work that builds them".

Registered users can see each company's valuation cap, contributor pool, open roles, team holdings and some financials. Listings can be filtered by stage (pre-seed to growth), traction, what the company is seeking (contributors, capital or both) and sector.

The marketplace is small. In October 2026 it showed four companies, and one of them is Smart Block Island itself, under the ticker $SBI. The others were MoreCPA, Chain Lane LLC and Brazos Valley Marketing.

Who Smart Block Island is for

Smart Block Island suits a small or mid-sized private company, often US-based, that hands out equity to staff, advisors or contributors. It works best for a firm that wants vesting and cap table records run automatically, and that has an accountant or attorney willing to work in the tool. The partner program is built around that advisor.

It is a weaker fit in three cases:

• a venture-backed startup heading for a priced round, where investors and their lawyers expect a standard cap table tool;
• a company that wants its shares to trade, since the platform records ownership but offers no secondary market;
• a crypto-native team that wants to check its records on a public chain, since the company doesn't publish which chain it uses or any contract addresses.

Is Smart Block Island safe? Risks and limitations

The biggest gap is openness. The site doesn't name the blockchain that holds the ownership records, and the pricing page speaks of "private blockchain record-keeping". The Circle listing names Ethereum, OP Mainnet and Polygon PoS, but only for its USDC and wallet link, not the cap table. We found no public contract addresses, so we couldn't check who can upgrade the contracts. You can't check the records on a public explorer yourself.

We found no public security audit of its smart contracts, and the site lists none. Wallet custody is also vague. The Circle listing calls the model non-custodial and names Circle's Programmable Wallets, but the main site doesn't say who holds the keys.

The legal side matters most. A token is only as strong as the agreement it links to. It doesn't replace company law, state filings or securities rules, so a firm still needs a lawyer. Smart Block Island is also a small private company with no disclosed outside funding. Your records depend on it staying in business, though it says you can export your data if you leave.

Smart Block Island vs Carta, Pulley and Securitize

Smart Block Island sits between plain cap table software and regulated firms that issue tokenized shares.

• Carta and Pulley are the cap table tools most startups and their investors already know. They're the safer pick for a firm raising venture money. Smart Block Island's edge is a token-based record, automatic payouts and a pitch aimed at small firms and their accountants.
• Securitize is a regulated firm that issues tokenized shares and runs a venue to trade them. It suits issuers who want shares that can trade within the rules. Smart Block Island offers no trading and doesn't claim that status.

If you want a tried, investor-standard ledger, pick Carta or Pulley. If you want shares that trade, pick a regulated issuer. Pick Smart Block Island if you want ownership records that run themselves and you're at ease with a young product.
