12 Best American Express Business Alternatives & Competitors (2026)

Stripe Treasury enables embedded banking for platforms and marketplaces. It is infrastructure rather than a direct user-facing product like Karat, so it does not provide the all-in-one dashboard, custom Visa cards, or AI bookkeeping that creators use daily within Karat.

Ramp is a US spend-management platform offering corporate cards, automated expense tracking, and AI-powered savings insights. It provides strong accounting integrations and rewards but lacks native Pix or boleto support, making reconciliation harder for Brazilian teams. Pricing is usage-based with no monthly fees, contrasting Conta Simples contact-based model and local payment focus.

Expensify specializes in receipt scanning and expense reporting with broad ERP syncs. It lacks native corporate cards and Brazilian payment rails, requiring separate card providers. Teams comparing it to Conta Simples often note weaker real-time dashboards and no global USD account without IOF.

Mercury offers business banking with strong API integrations and no-fee international wires, popular among startups. It lacks Karat's creator-specific credit approvals based on social metrics and does not host industry events. Mercury focuses on tech teams needing developer tools rather than agencies managing brand deals and irregular creator income.

Found combines banking with tax tools for freelancers, automating quarterly estimates. It does not offer the agency-scale bulk payments or custom-branded credit cards that Karat provides for teams managing multiple client entities and brand deals.

SAP Concur focuses on enterprise travel and expense management with policy enforcement. It excels at compliance reporting but requires third-party cards for Brazilian use cases. Conta Simples offers simpler card issuance and local payments without the heavy implementation typical of Concur.

Bluevine supplies business checking with competitive APY and invoicing features for SMBs. While it offers solid banking basics, Bluevine lacks Karat's integrated credit card approvals based on social proof and the creator community events that differentiate Karat for influencers and agencies.

Caju is a Brazilian employee-benefits and spend platform with prepaid cards and basic expense tracking. It offers local Pix support but fewer AI insights and no international USD account. Pricing is subscription-based, positioning it as a lighter alternative for smaller teams than Conta Simples enterprise features.

Chase offers corporate cards and treasury services with robust reporting. It targets large enterprises and provides global reach yet has minimal Brazilian payment support. Conta Simples differentiates with faster virtual card creation and AI insights tailored to Brazilian spend patterns.
