Carta is the dominant US cap table platform, built around 409A valuations, ISO management, and the US startup financing stack. For German GmbHs, that means paying for features you cannot use while working around the ones you need: §19a EIP compliance, German governance workflows, EU data residency, and contract management are all outside Carta's core. GAIA is built from the German legal layer up: cap table, contracts, signing, governance, and the employee portal in one platform. If your company is a German GmbH and your equity program needs to work under German law, the two platforms are not close alternatives.
This comparison is written for founders who have Carta on their shortlist and want an even-handed read. Both platforms are reviewed on what they genuinely do well, where the gaps are, and which company profile fits each. The goal is not to win a debate: it is to help you pick the right tool for your legal structure and stage.
Where is Carta genuinely strong?
Carta built its position on the US startup market and it remains the default choice for companies operating in that context.
US-headquartered and US-flipped companies. If your company is a Delaware C-corp, or if you have flipped to a US structure to take US institutional funding, Carta is built for you. 409A valuations, ISO and NSO management, Form 3921, Rule 701 disclosures, 83(b) elections, and ASC 718 reporting are native and tightly integrated. A German-first platform cannot replicate that depth for a US entity.
409A valuations bundled in. US companies need an annual 409A to set the fair market value of their common stock, and paying for them separately from a third party typically costs $2,000 to $5,000 per valuation. Carta bundles them in higher-tier plans: a meaningful cost advantage for US-incorporated startups.
US VC brand recognition. Carta is the platform US institutional investors expect. At Series B and beyond with US lead investors, running on Carta reduces friction at diligence. Some US VCs request Carta-format cap table exports as standard.
Late-stage liquidity programs and secondaries. Carta's Liquidity product handles tender offers and secondary transactions at scale. For a late-stage US company managing complex liquidity events, that infrastructure is hard to replicate.
Where Carta is the right call: US C-corp, US-primary investor base, or a company actively planning a US IPO path. The platform was built for this scenario and is excellent at it.
Where does Carta fall short for a German GmbH?
The gaps are structural, not cosmetic. Carta's product is organized around US legal and tax concepts. German companies are working around those concepts from day one.
No §19a EIP compliance workflow. The post-2024 §19a EIP (Employee Incentive Program) with real shares is the most tax-efficient employee equity structure available to qualifying German startups, and it is increasingly a retention and hiring tool. Carta's Germany page supports VSOPs and acknowledges that notarization still applies for share issuance, but there is no native EIP workflow: no pooled-entity structuring, no §19a deferral tracking, no employee-side compliance management. For a German founder whose team is asking about EIPs, Carta is not a tool that solves that problem.
US-centric features dominate the product. The Carta feature set is organized around 409A, Form 3921, ISO management, 83(b) elections, and ASC 718 reporting. German GmbHs pay for these features and cannot use any of them. The German-relevant surface area (VSOP management and electronic signatures) represents a small part of the product, not its core.
No German governance layer. Carta offers board consents and board meeting management, designed for US board governance. German GmbHs operate under different rules: Gesellschafterbeschlüsse, Handelsregister filings, and the Gesellschafterliste. Carta has no native German governance workflow. Companies run those processes in separate tools or on paper, then update Carta manually.
No contract and document management. For a German GmbH, issuing equity means generating grant agreements, employment addenda, shareholder resolutions, and participant-agreement documents, sometimes notarized. Carta is a cap table and equity administration platform. It does not manage the document layer. GAIA's design is built around the principle that the contract and the cap table entry should not live in separate systems.
Pricing scales against growth. Carta's pricing is per-stakeholder, tiered by plan, with stakeholder caps and overage fees. Companies that raise follow-on rounds, add option-grant participants, and grow their investor base pay more at each renewal. Annual price escalators of 5 to 10% are common in Carta contracts. Founders who closed a seed with one pricing expectation have found their cost significantly higher at Series A. That structural dynamic is the source of the repeated complaints about surprise price increases after funding rounds.
No EU data residency. Carta is a US company and its infrastructure is US-based. For German companies subject to GDPR and for investors who take European data residency seriously, storing a complete cap table (which contains full shareholder identities, addresses, and equity positions) on a US-hosted platform is a compliance conversation that should not have to happen.
The 2024 secondary data incident. In early 2024, Carta was publicly accused of using cap table data to identify and pitch private secondary transactions to shareholders at competing portfolio companies. The company acknowledged the issue and has made commitments around data-use policy since. The incident did not change the product, but it did put data-use provisions firmly on every founder's vendor checklist. When evaluating any platform that holds your full cap table, reading the data use policy is worth the fifteen minutes.
How does GAIA compare?
GAIA is a German legal-tech company built by lawyers, organized around the German and European equity stack.
The platform connects cap table, contracts, signing, governance, and the employee portal in a single workflow. The design principle is that equity events (issuing a VSOP grant, setting up an EIP pool, filing a shareholder resolution) involve documents, signatures, compliance steps, and cap table updates that should not be split across four tools. GAIA keeps them together.
The specific advantages for a German GmbH:
Native §19a EIP support. GAIA is structured around the post-2024 EIP, including pooled-entity setup, §19a deferral tracking, and employee-side compliance. For a founder who wants to offer the most tax-efficient incentive structure available under German law, this is the core case for using GAIA rather than building the workflow across a cap table tool, a law firm, and a spreadsheet. See VSOP vs ESOP vs EIP: which model for a German GmbH for a full comparison of the instruments.
GmbH-native cap table management. The Gesellschafterliste, notarized share transfers under §15 GmbHG, and the relationship between the commercial register and the live cap table are built into GAIA's model. The fully-diluted picture (combining the register with outstanding incentive grants) is what GAIA tracks, because that is the gap the notarized register alone does not close.
German governance workflows. Shareholder resolutions, board consents under German law, and governance documentation are native features. Companies do not need a separate tool for the corporate-law layer.
EU data residency. GAIA's infrastructure is EU-based. Cap table data (shareholder identities, positions, grant details) stays within European data-residency boundaries.
The employee portal. Employees see their grants, vesting status, and modeled exit value in a portal built for comprehension, not just record-keeping. An equity grant no one understands does no retention work.

Which platform fits your company?
Choose Carta if: Your company is a Delaware C-corp, your investor base is primarily US institutional, you need bundled 409A valuations, or you are on a US IPO path. Carta is the right tool for the ecosystem it was built for.
Choose GAIA if: Your company is based in Europe (especially a German GmbH), you want to run an EIP under §19a alongside or instead of a VSOP, you need the cap table and the contract layer in one place, or EU data residency is a requirement. GAIA is built for this scenario.
If you are evaluating both: The question is where your legal structure and your equity program sit. A US C-corp with German employees is closer to the Carta use case. A German GmbH running a German equity program is closer to GAIA's. Most German founders who have evaluated both find that Carta's German surface area is thin relative to the cost of a full Carta subscription.

FAQ
Can Carta manage a German VSOP?
Carta supports phantom share (VSOP) issuances for German companies and electronic signatures in compliance with the Bundesdruckerei. It does not, however, offer a native §19a EIP workflow, German shareholder resolution management, or integrated contract handling. For companies whose equity program goes beyond VSOP administration, that gap requires additional tools.
Does Carta have EU data residency?
No. Carta is a US company with US-based infrastructure. Cap table data (which includes full shareholder identities, positions, and grant details) is stored outside the EU. For German companies that treat GDPR compliance or EU data residency as a requirement, this is a structural issue rather than a configuration option.
What happened with Carta's 2024 data incident?
In early 2024, Carta was publicly accused of using cap table data to identify shareholders at portfolio companies and pitch them on secondary transactions, sometimes in competition with those companies' own secondary programs. Carta acknowledged the issue, terminated the team involved, and has made data-use policy commitments since. The incident did not affect the product's functionality but prompted many founders to review data-use policies more carefully before selecting a cap table vendor.
How does Carta's pricing scale for a German company?
Carta prices per stakeholder with tiered plans. As a German company raises follow-on rounds, adds option-grant participants, and grows its investor base, the stakeholder count rises and renewal costs typically step up. Annual price escalators of 5 to 10% are common in Carta contracts. Companies that were comfortable with their seed-stage pricing have frequently found their Series A cost materially higher. Carta does not publish exact pricing for paid tiers; quotes are custom.
Is GAIA available for non-German European companies?
Yes. GAIA works with companies across Europe. Cap table management, contract workflows, employee portal, and governance are built around the cap table and board structure in a way that translates well beyond Germany. The one layer that is specific to German entities is the §19a EIP: that deferral mechanism is German tax law and applies only to companies structured under German law. For European companies outside Germany, GAIA covers the core equity management workflow; the EIP simply would not be part of the picture.
