Core10

aid: core10
name: Core10
description: 'Core10, Inc. is a U.S.-based fintech software development and API integration firm founded in 2016 by Lee Farabaugh
  and Jeff Martin, headquartered in Franklin, Tennessee with delivery centers in Martin, Tennessee and Huntington, West Virginia,
  built on a domestic-outsourcing model it trademarked as Hereshore(R). Core10 wrote custom software, core-banking integrations
  and API layers for community banks, credit unions and fintechs, and acquired Accrue Technologies in 2021 to add a Salesforce-based
  digital lending, account opening and treasury onboarding platform. In January 2024 it spun its implementation practice out
  as Monarch, and the Core10 brand has since been retired: core10.io now 301-redirects to monarchfts.com, where Monarch operates
  as an Intapp DealCloud implementation, configuration and managed-services consultancy for private capital firms, while the
  Accrue platform trades independently at getaccrue.com under its own leadership. Core10 built API integrations for other
  companies for nearly a decade but never published a developer program, public API, SDK or machine-readable contract of its
  own, and as of 2026-08-11 neither successor brand does either.'

    an Intapp DealCloud consultancy, while the Accrue platform it acquired trades separately at getaccrue.com; Core10 sold
    API integration work for a decade and never published an API, a developer portal or a spec of its own, and neither successor
