# Agency Tech Stack

Every agency has a tech stack. **Most didn't design theirs; it happened**. Notion because someone liked it at a previous job. Slack because the first big client insisted. Figma because the lead designer refused to use anything else. Google Drive because it was free. Harvest for time tracking, QuickBooks for invoicing, a project management tool the team argues about every six months. The result is ten to fifteen tools that don't talk to each other.

The problem isn't having many tools—it's that **knowledge fragments across them**. The brief lives in Notion. The approved assets live in Figma. The client history lives in email. The pricing decisions live in Slack. When a freelancer asks a question, finding the answer means searching four apps and asking two people. The stack is complete on paper and impenetrable in practice.

Agencies usually respond by trying to consolidate—move everything to one platform, force everyone to the same tool. **It rarely works**. Designers want Figma. Writers want Docs. Project managers want the tool that matches how they think. Forcing uniformity breaks workflows, and shadow tools appear within weeks. The real problem isn't tool diversity; it's that knowledge can't be found across the tools you already have.

heykiku sits across an agency's tech stack without replacing any of it. Upload the documents that hold agency knowledge—briefs, [brand guidelines](https://heykiku.com/glossary/brand-guidelines), [SOPs](https://heykiku.com/glossary/standard-operating-procedures), client history, past work—and one AI assistant answers questions from all of them, regardless of which tool they originally came from. Role-based access means freelancers can query the knowledge they need **without being added to your Notion workspace**. The stack stays the same; the knowledge becomes searchable.
