About Doublemind
We build AI teammates for the work that shouldn't need a human doing it manually.
Sia is the first. She runs social media for growing brands today. She won't be the last.
Built on the world's most capable AI models
- Google Gemini
- Google Vertex AI
- OpenAI
Built with these models. Vendor list pending engineering confirmation before launch.
What we believe
- 01
A teammate, not a tool.
Tools wait for instructions. We build things that move the work forward on their own, and check with you before anything ships.
- 02
Brand-first, always.
Generic AI output is worse than no output. Everything we build starts by learning who you are before it creates anything.
- 03
You stay in control.
Autonomy without approval isn't a feature, it's a risk. Every teammate we build asks before it publishes.
- 04
Premium craft over AI slop.
Fast and cheap-looking are not the same as fast and good. We hold our output to a bar most AI tools don't bother with.
- 05
Built for teams with better things to do.
The work that eats a day should take ten minutes. That's the whole point.
What we've built so far
Every format
Posts, carousels, stories, reels and long-form captions created from one brief.
One brand memory
Voice, audience, positioning and your no-go list, applied to every asset, set once, never re-explained.
Approval first
Nothing publishes without your yes. Autopilot is a setting, never a default.
15 free tools
An open library of AI tools anyone can use, no account required.
From one AI teammate to a whole team of them.
Sia is where we started. She won't be where we stop.

The vision
Doublemind becomes the place teams come to hire their next AI teammate, however many their work needs.
Making history since 2025.
Key moments in Doublemind's story, from the first version of Sia and her brand memory to multi-platform publishing, every content format, and the AI teammates now in development.
2025 – 2026
Early 2025
Doublemind starts building Sia, an AI teammate for social media, designed around brand memory instead of one-off prompts.
Mid 2025
Sia's brand memory goes live: voice, audience, positioning and no-go list, learned once and applied to everything she creates.
Late 2025
Multi-platform publishing arrives. Instagram, LinkedIn, TikTok, Facebook and X, each with the right format, crop and copy length.
Early 2026
Every format from one brief: images, carousels, stories, videos, reels and long-form articles.
Mid 2026
Planning and approval workflows mature, weekly content plans, autopilot as an opt-in setting, nothing published without your yes.
Now
Sia runs social media for growing brands, backed by a free library of 15 AI tools open to anyone.
