Solid is a full-stack banking-as-a-service platform that provides fintech companies and enterprises with the infrastructure to build deposit accounts, card programs, and lending products through a unified API. Founded in 2018 and headquartered in San Jose, California, the company has raised over $63 million in funding. Solid serves more than 50 fintech customers across consumer and B2B financial product segments, providing a comprehensive BaaS stack including account management, card issuance, ACH, compliance, and lending infrastructure.\n\nSolid's platform differentiates through its breadth — covering the full range of financial product types from a single integration rather than requiring customers to assemble capabilities from multiple vendors. Its card issuing module handles both virtual and physical debit and credit cards with programmable spend controls. The lending infrastructure supports personal loans, business credit lines, and BNPL product configurations. An account management layer provides multi-currency deposit accounts, ACH, and wire capabilities with built-in KYC and AML compliance.\n\nSolid has focused on serving fintech startups and mid-market platforms that need a comprehensive embedded finance stack without the complexity of managing multiple bank partnerships and infrastructure vendors. The company's compliance framework is configurable to different risk profiles, allowing customers to tune KYC and AML parameters to their specific market segment. Solid's 2025 roadmap has emphasized deeper credit infrastructure capabilities and cross-border payment support to serve fintechs with international user bases.
Global payments infrastructure founded by Patrick and John Collison (YC W10); $1.4T payments volume in 2024; $18B+ revenue; $106.7B valuation as of Sept 2025; powers everything from startups to Fortune 500 companies with developer-first API design.
Stripe is a global payments infrastructure company founded in 2010 by Irish brothers Patrick and John Collison, headquartered in San Francisco, California and Dublin, Ireland. Stripe was born from the insight that accepting payments online was unnecessarily complex for developers, and that a well-designed API could unlock an entire generation of internet businesses. The company went through Y Combinator's Winter 2010 batch and grew to become the defining payments infrastructure layer of the modern internet economy, processing payments for businesses in virtually every industry worldwide.\n\nStripe's platform provides payment processing, fraud prevention via Stripe Radar, subscription billing, revenue recognition, banking-as-a-service through Stripe Treasury, corporate card issuance, identity verification, and tax compliance tools. It serves a spectrum from early-stage startups to publicly traded enterprises including Amazon, Google, Salesforce, and Shopify. Stripe's developer-first philosophy — comprehensive documentation, SDKs in every major language, and a sandbox testing environment — created an ecosystem of millions of businesses built entirely on its infrastructure.\n\nStripe processed $1.4 trillion in total payment volume in 2024 and generates over $18 billion in annual revenue, with a valuation of $106.7 billion as of September 2025. The company has remained private longer than most comparably sized technology companies, giving it flexibility to invest in long-term product expansion. An April 2024 partnership with Apple Pay extended Stripe's reach further into mobile and in-store commerce. Stripe competes with Adyen, Braintree (PayPal), and Square, but its developer ecosystem depth and global infrastructure make it the default payments platform for a generation of technology companies.
