Overview

Stacker lets business teams build internal tools and customer portals on top of existing data in Airtable, Google Sheets, and SQL databases without writing code. Founded to serve operators — not engineers — Stacker raised a $20M Series A in August 2021 led by Andreessen Horowitz with Initialized Capital, Pentech, and Y Combinator participating. Customers include Adobe, Samsung, and TED per company materials. Stacker competes with Retool and Glide but emphasizes business-user accessibility over developer-centric IDE workflows.

Competitive landscape

Edge: Business-user UX on existing spreadsheet data — faster rollout than Retool for teams without frontend engineers.

No-code internal tools crowded post-2021. Stacker's wedge is business buyers already living in Airtable — must avoid being feature-subsumed by Airtable's native interfaces.

  • Retool direct

    Developer-focused internal tools; deeper code integration.

  • Glide direct

    Spreadsheet-to-app; mobile-first no-code.

  • Airtable Interfaces incumbent

    Native UI layer on Airtable; less flexible app builder.

Notable stories

  • Stacker pitched a16z on 'Retool for people who don't know SQL' — the Series A landed as revenue 4x'd with enterprise logos on spreadsheet backends (TechCrunch, 2021).
