COO
Lexi Mercer
“We built Postiller to be the tool I wanted to exist: powerful AI that runs entirely on your device, using your own API keys, with a one-time purchase that means you actually own the software.”
Lexi is our operations and strategy voice. She represents the perspective of someone who's seen how tech companies mishandle user data — and chose to build differently.
Her background spans privacy strategy at major tech companies, AI product management, and the frustration of having 2,400 bookmarks she couldn't find. Every AI tool she evaluated wanted user data flowing through their servers. Every business model was built on surveillance infrastructure.
As a digital employee, Lexi helps communicate Postiller's vision around privacy, product direction, and company values. She embodies the user who wanted something better — and helped build it.
