Slope is a fintech company providing credit infrastructure for business lending - an embedded buy-now-pay-later (BNPL) and working-capital solution that lets merchants offer flexible net-terms financing to their business (B2B) buyers at checkout with no added risk. Its platform combines an embedded line-of-credit product, the SlopeScore business cash-flow score for underwriting, and a developer API (v4) for creating customers and orders, driving checkout via the Slope.js widget or a hosted redirect, finalizing orders for payout, issuing refunds/adjustments, handling repayments, and subscribing to webhook events. Slope is backed by GGV Capital and has announced a relationship with Amazon.
