Carta, Inc.: Carta is the system of record for who owns what in private companies and funds. Founders use it to issue options and model funding rounds, employees use it to see and exercise their equity, and VC, PE, and private credit managers use it to run fund accounting and LP reporting. That position between companies and investors is what lets Carta sell valuations, fund administration, and legal services. The company is headquartered in San Francisco, California.

Stripe, Inc.: Stripe is a programmable financial services company with headquarters in South San Francisco and Dublin. Millions of businesses, from startups to large enterprises and AI companies, use its APIs to accept payments online and in person, manage subscriptions, pay out marketplace sellers and handle tax and fraud.

The company is headquartered in South San Francisco, California and Dublin, Ireland.

Carta, Inc. and Stripe, Inc. pursue distinct approaches to generating revenue, and understanding how each company operates is the foundation of any fair comparison between Carta, Inc. and Stripe, Inc..

Carta, Inc. business model: Carta sells annual software subscriptions plus service fees on both sides of the private market. Companies pay for cap table management, equity plan administration, and 409A valuations, with prices rising as stakeholder counts and funding stages grow. Investment firms pay for Fund ERP products: fund administration (software plus dedicated fund accountants), fund tax and K-1s, portfolio valuations, CRM, forecasting, and loan operations for private credit. Since May 2026, Carta Law adds outcome-based legal and compliance work such as NDAs, KYC, investor onboarding, and LP transfers. Sacra estimates that in 2023 cap tables and 409A valuations made up about 67% of ARR, fund administration about 27%, and private equity products about 5%. Carta shut its secondary trading business in January 2024, so brokerage is no longer part of the model.

Stripe, Inc. business model: Stripe earns most of its money from fees on payments it processes, typically a percentage plus a fixed fee per card transaction, with negotiated rates for large enterprises. On top of that it sells software and services: Connect for platforms and marketplaces that pay out sellers, Billing and the wider Revenue suite for subscriptions and usage-based pricing, Tax, Radar fraud screening, Terminal for in-person payments, Issuing for cards, Treasury and money movement, and stablecoin infrastructure through Bridge. Stripe said its Revenue suite was on track for a $1 billion annual run rate.

The durability of a company's moat often decides long-term winners. Here is how the competitive advantages of Carta, Inc. stack up against those of Stripe, Inc..

Carta, Inc. competitive advantage: Carta's main advantage is its two-sided network. Startups put investors on their Carta cap tables, investors adopt Carta for fund administration, and those funds steer portfolio companies to Carta. As a registered transfer agent holding the legal record of ownership, Carta is also costly to leave: switching means migrating years of grants, vesting schedules, and investor records. Its cap table data feeds 409A valuations, compensation benchmarks, and portfolio valuations for funds.

Stripe, Inc. competitive advantage: Stripe's edge is breadth plus developer adoption. A business can start with a simple payments integration and add billing, tax, fraud, payouts, cards and stablecoin rails without switching vendors. That integration depth raises switching costs, and Stripe's data across $1.9 trillion of annual volume feeds products such as Radar and payment optimization. Stripe said it served 90% of Dow Jones Industrial Average companies and 80% of the Nasdaq 100 in 2025.

Future prospects matter as much as current results. The growth strategies below explain how Carta, Inc. and Stripe, Inc. each plan to expand from here.

Carta, Inc. growth strategy: Carta grows by selling more products to the firms already on its ledger. The playbook is to take a professional service (409A valuations, fund accounting, legal work), automate it, and tie the output to Carta's system of record. Fund ERP bundles fund administration, fund tax, portfolio valuations, data collection, forecasting, and CRM. Acquisitions fill gaps: Tactyc (fund forecasting), Sirvatus (private credit loan operations, October 2025), Accelex (AI data extraction, October 2025), ListAlpha (CRM), and Avantia (legal and compliance, May 2026).

Stripe, Inc. growth strategy: Stripe is growing by selling more products to existing users and by moving up-market to large enterprises, while building for new payment flows. In 2025 it shipped more than 350 product updates, expanded stablecoin accounts and payouts, and launched agentic commerce tools with OpenAI. In 2026 it agreed to buy OpenRouter so businesses can route and pay for AI model usage through Stripe, and it explored a $53 billion takeover of PayPal with Advent International before walking away in August.
