The AI stack for a solo founder

A solo founder's constraint is time, not money, and the right AI stack is the one that lets one person credibly cover engineering, support, growth, and ops. The philosophy: pick one strong tool per function rather than a sprawling collection, and lean on tools that compose rather than ones that each demand their own workflow. The highest-leverage starting point is a coding agent (if you're technical) plus an AI meeting tool plus a no-code automation layer for the operational glue. Resist the urge to buy an all-in-one platform before you've run a single function with discipline — the all-in-ones optimize for the founder who hasn't built one yet, and you'll outgrow their defaults fast. The stack below targets a real solo operator: enough capability to cover the full surface of a small company, low enough cost to run pre-revenue, and composable enough that you can swap any single tool without rebuilding everything. The mistake solo founders make is either under-investing (trying to do everything manually to save $200/month while burning the one resource that's actually scarce, their time) or over-investing (buying enterprise platforms whose capability they can't use yet). The right move is a lean, high-leverage stack you actually operate, expanded one function at a time as the business grows.
