    The platform itself allows you to manage all aspects of share and option management concisely in one place. The automations and integrations save you time. But while the platform is great, it is the team that makes Vestd stand out.

    Jenny James · Chief Operating Officer, Findr

    Great platform. The team always provide brilliant support. I would definitely recommend using Vestd to anyone who needs to set up and administer an EMI scheme.

    Sarah T. · Director

    Frequently asked questions

    Are these tools really free to use?

    Yes. Every calculator and diagnostic on this page is free to use. Some results screens offer an optional way to save or download your numbers, or to talk to a specialist, but that's never a requirement.

    How accurate are the results?

    Each tool uses the same maths that underpins share scheme and cap table modelling on the Vestd platform. They're a strong, reliable estimate based on what you enter, but they don't replace formal tax, legal or accounting advice for your specific situation.

    Is my data stored anywhere?

    No. Everything you type into these calculators stays in your browser for that session. Nothing is sent to Vestd's servers unless you explicitly choose to download a CSV or book a call with our team.

    Can I get help interpreting my results?

    Yes. Most results screens include an option to book a free call with a Vestd equity specialist, who can walk through your numbers and what they mean for your next share scheme, funding round or valuation.

    Our team, content and app can help you make informed decisions.
    However, any guidance and support should not be considered as 'legal, tax or financial advice.'
