Capdesk was acquired by Carta in 2022 and rebranded Carta Europe. Customers are now being migrated onto US-based infrastructure — and the clock is ticking.
If you're evaluating alternatives, here's what to look for: a platform that was built for global operations from day one, not adapted for them.
Slice is the global equity platform trusted by fast-growing companies across the UK, Europe, Australia, and beyond — with AI-native compliance, automated tax, and onboarding in under two weeks.


In 2022, Capdesk — one of Europe's leading equity management platforms — was acquired by US-based Carta. The platform was initially preserved under the Carta Europe brand, but customers are now receiving notice about migration to Carta's US infrastructure.
For European companies, this creates real operational questions: Will the platform continue to understand European-first equity schemes like EMI and CSOP the way Capdesk did? Will data remain subject to European data protection standards? Who will be accountable for compliance in your specific jurisdictions?
These aren't hypothetical concerns — they're exactly the kind of questions that equity administrators, CFOs, and corporate counsel need answered before a migration deadline arrives.
The good news: if you're evaluating now, you have time to make the right choice rather than a reactive one.
THE SLICE DIFFERENCE
The difference between a good and a great equity platform for international companies is whether compliance is automated or manual. Slice's AI engine continuously monitors 60+ countries, sends pre-emptive alerts, and recalculates tax obligations automatically when employees relocate — no external counsel required for day-to-day operations.
Slice currently supports 60+ countries and can expand as your team grows. When you hire your first employee in a new jurisdiction, the compliance logic is already there. You don't need to contact support and wait for someone to check whether the country is covered.
Unlike platforms where changes require a support ticket and a 5-business-day response time, Slice's workflows are self-serve and no-code. Grants, exercises, terminations, and compliance actions can all be handled in the platform — in minutes, not days.
Yes. Slice supports a wide range of equity plans, awards, and financial instruments:
Plans and schemes: EMI, CSOP, and ESOP
Equity awards: Options, RSUs, RSAs, growth shares, and phantom shares
Financial instruments: Warrants, SAFEs, and convertible notes
For UK companies specifically, Slice handles HMRC reporting requirements, Companies House filings, and the full compliance lifecycle for tax-advantaged schemes.
Your data, cap table, grant history, and compliance records all transfer intact. Slice's onboarding team conducts a full audit of your existing records, verifies document completeness, and validates data accuracy before you go live. The process is managed entirely by Slice specialists — your team provides documents, we handle the rest.
Most companies complete the full migration in under two weeks. Slice's onboarding process is specialist-led by ex-lawyers and equity professionals, and is completely free. The timeline is structured so you have continuity throughout — no gap in compliance monitoring or equity administration.
Yes. Slice handles HMRC reporting requirements and supports the full compliance lifecycle for UK tax-advantaged schemes including EMI, CSOP, EIS, and SEIS. Companies House requirements are also covered. Unlike the original Capdesk experience being migrated into Carta's US infrastructure, Slice maintains deep UK and European compliance logic as a core capability.
Slice works for any private company with employees across multiple countries. The platform currently supports 60+ countries and is purpose-built for the complexity of cross-border equity — including employee mobility between jurisdictions, multiple accounting frameworks (US GAAP and IFRS 2), and varying tax treatment by country. Many Slice customers have teams across Europe, the US, Israel, Australia, and beyond.
