10 Best American Express Business Alternatives & Competitors (2026)

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.

Ramp delivers corporate cards with automated expense controls and cash-back rewards aimed at cost-conscious finance teams. It does not match Karat's focus on custom stainless-steel cards for personal branding or rapid limit increases via text for creators during high-profile campaigns.

Brex provides corporate cards and rewards tailored to SaaS spend with high limits for venture-backed companies. Unlike Karat, Brex does not emphasize creator income patterns or automatic 1099 generation for talent payments, and its rewards are less flexible for non-SaaS businesses such as YouTube channels or influencer agencies.

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.

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.

Novo provides free business checking aimed at freelancers and small teams with simple transfers. It does not include credit cards or the advanced multi-entity permissioning and bulk international payment tools that Karat offers agencies handling complex creator payouts.

Relay focuses on multi-account business banking with spend controls and approval workflows. It lacks Karat's rewards-based credit cards and creator-centric onboarding that approves users traditional banks reject, making it less ideal for influencer businesses.

Capital on Tap issues business credit cards with cash-back rewards and flexible repayment. It does not integrate AI bookkeeping or high-yield checking accounts the way Karat does, limiting its usefulness for creators seeking a single dashboard for all finances.
