AI Productivity

The challenge

Small businesses lose significant hours every week to repetitive administrative tasks. Hiring dedicated staff is expensive; existing tools automate fragments but never the whole workflow.

Discovery & research

We shadowed small-business operators to map where their time actually went, then prioritized the three workflows - email, calendar, invoicing - where AI assistance would return the most hours with the least behavior change.

The solution

AI that acts, not just suggests.

We designed an assistant that completes tasks end to end: drafting and triaging email, negotiating calendar slots, and generating invoices - all reviewable from a single dashboard with smart suggestions and analytics that show hours saved.

01DiscoveryStakeholder workshops, competitive analysis, and user research to frame the real problem.
02DefinitionProduct strategy, prioritized roadmap, and success metrics agreed with stakeholders.
03DesignDashboard-first design system with an AI activity feed users can audit and correct at a glance.
04ValidationWeekly prototype tests with operators validated trust in AI actions before each build sprint.
