# Left Hook > Left Hook is an integration services company helping software companies and growing businesses connect the tools they run on. Founded in New Hampshire, we build, maintain, and scale integrations across 300+ platforms — from native SaaS connectors to business workflow automation. We specialize in working with SaaS companies ($1-50M ARR) and SMBs looking to automate operations. Left Hook offers four engagement models: Consultation (deep dive into your needs), Delivery (expert implementation), Outcome Ensuring (making sure everything works), and Ongoing Support (continued partnership). We work across 300+ platforms including HubSpot, Salesforce, Shopify, Zapier, Slack, Microsoft, Google, Atlassian, Stripe, and many more. Our open-source integration framework, Frigg, powers many of the integrations we build and is available on GitHub at github.com/friggframework. --- ## Services ### Managed Integrations URL: https://lefthook.com/services/managed-integrations End-to-end integration management for SaaS companies building native integrations for app marketplaces.
