Highline

aid: highline-fi
name: Highline
description: 'Highline is an embedded payment infrastructure company whose Pay by Paycheck

  product captures funds from a consumer''s payroll before they reach the

  checking account and routes them to billers and lenders. The platform pairs

  with payroll providers to create a split direct deposit at payroll run time,

  so designated bills are paid on time and in full, and the remainder is

  deposited to the consumer''s bank as normal. Highline ships an API-first

  developer experience with hosted documentation at docs.highline.co, a Highline

  Link client widget, webhook-based notifications, sandbox simulations, daily

  ACH settlements, and an llms.txt for AI agents. The company is sometimes

  referenced as highline.fi but operates today at highline.co.
