Frequently asked questions

How much does Mantle cost?

We recognize that changing providers isn’t a light decision. To simplify this process, we're offering Carta users an entire year of Mantle for free. After the first 12 months, you'll benefit from flat rate pricing of $100 per month for unlimited stakeholders, no strings attached.

How long does the migration process take?

Migrating from Carta to Mantle typically takes 1-5 business days. Once you add Mantle to your Carta account, we’ll take care of the migration and hand you the keys once your account is ready!

What types of companies does Mantle support?

Mantle supports all registered C-corps in US or Canada (no LLCs at this time). We have companies that are freshly incorporated using our platform all the way up to companies with hundreds of employees.

How many stakeholders are included?

Healthy cap table management happens when all stakeholders are involved, communicate transparently, and can collaborate seamlessly. That’s why all Mantle plans include unlimited stakeholders so you can invite as many users as you’d like, all at no extra cost.

How does Mantle use AI?

Mantle leverages AI across several platform features, specifically within the onboarding and document processing stage. Using Large Language Models (LLMs), we’re able to import a collection of unorganized, bespoke documents, extract key information, and rapidly normalize it into our own data models.

Our AI tools also conduct real-time health checks, which identify errors in customer data ranging from minor discrepancies to mistakes that could have cost them tens of thousands of dollars in legal fees down the road.

What is OCF compliance?

The Open Cap Table Coalition (OCT) is a collection of over 31 law firms, equity management providers, and other startup ecosystem players, aimed at improving the interoperability, transparency, and portability of startup cap table data.

In addition to being an active board member of the OCF, Mantle remains the only equity management provider to be 100% OCF-compliant. We offer Mantle users the ability to download their cap tables in Open Cap Table Format (OCF) directly from the platform in one click. This ensures you can export your cap table data in an industry-standard format.

Is Mantle SOC2 compliant?

Mantle complies with Service Organization Control Type 2 (SOC 2) standards and follows security guidelines established by the American Institute of CPAs (AICPA). We adhere to the best practices in managing and protecting your data.
