Mark A, made less serious and more for tech founders: the mic's grille becomes a face, the proportions get rounder and chunkier, the head tilts like it's listening, and each version gets one playful move. Orange stays the main colour; lilac joins as a tech accent. The wordmark keeps the voice idea: the two l's are bouncing sound bars.
On the name: only tellme.co came back free (the .com, .ai, .app, .io and get/hq variants are registered), and two AI products already use "TellMe": a consumer AI assistant app and an AI museum-guide startup. Neither is in B2B content, so it's usable, but buy tellme.co now and get a trademark opinion before spending on it.
The wave is the friendliest and the clearest: a little mic-headed person, body shaped like a pen nib, waving hello. It feels like a teammate, not a tool, which is exactly the "24/7 Head of Content" pitch, and it still reads at app-icon size.
Use 4, typing as its animated state inside the product ("tellme is typing…") while posts are being written. Same character, so it's one brand, not two.
