About Decidi
The people behind it · Last updated 27 June 2026
Decidi is a product you are meant to put your name on the output of — so you deserve to know who builds it and why. This page answers both, plainly.
Who builds Decidi?
Decidi is built and operated by 8T20 Capital, an independent technology company founded by Andrew J. Taylor and based in South Africa. We build a small portfolio of AI-driven products; Decidi is the one focused on multi-model decision assurance — putting a real decision to a council of independent frontier models that debate and audit one another.
Why Decidi exists
One AI can be confidently wrong. It will give you a fluent, plausible answer to almost anything — and leave you crafting prompts, hoping nothing slipped. When the thing you are about to do is send, ship or sign something that carries your name, “it sounded right” is not good enough.
So we built Decidi around a simple idea: important work should not rest on a single opinion. Decidi hands your work to a council of frontier models — GPT, Claude, Gemini and Grok — plus expert personas that challenge each other, then an always-on Final QA audit looks for hallucinations before you ever see the verdict.
What we actually do
Decidi convenes multiple distinct, live models — not one model wearing different hats — through a gateway, assigns them to a structured debate, attributes every contribution to the model that made it, and synthesises a clear verdict you can download as a decision memo. Where the models disagree, we show you the disagreement, because that tension is often the most useful part of the decision.
The mechanics are documented openly on the security & model-transparency page and the how-it-works page.
Who 8T20 Capital is
8T20 Capital is an independent, founder-led technology company headquartered in South Africa, founded by Andrew J. Taylor. It designs and operates a focused set of AI-driven products to a single standard: build the thing properly, be honest about what it can and cannot do, and earn trust rather than assume it. Decidi is built and run by the same team, on that same standard.
For why Andrew built it in the first place, read the founder’s letter.
What we believe about AI
We think the honest position on today’s AI is that it is powerful and unreliable at the same time — and that the right response is not to trust one model harder, but to make several models check each other and to be transparent when they do not agree. Decidi is built to surface disagreement rather than hide it. The verdict is a synthesis to think with, not a guarantee to act on.
How we make money — and what we do with your data
Decidi is funded simply: you pay per decision. Credit packs start at $5, and a council costs what the underlying models actually cost to run, plus a transparent markup, metered live — failed model calls are not charged. We do not sell your content, and we never use your prompts, files, transcripts or verdicts to train any model. The full data posture is on the security page.
Decidi is decision support, not regulated professional advice. For decisions that genuinely require a licensed lawyer, accountant or other professional, Decidi will tell you so — it is built to surface issues and sharpen your thinking, not to replace qualified advice where the law requires it.
Questions about who’s behind Decidi
Who is behind Decidi?
Decidi is built by 8T20 Capital, an independent technology company founded by Andrew J. Taylor and based in South Africa. 8T20 Capital builds a small portfolio of AI-driven products; Decidi is the one focused on multi-model decision assurance.
Is Decidi a real company, or just a wrapper?
It is a real product built and operated by 8T20 Capital. Decidi calls multiple live frontier models from OpenAI, Anthropic, Google and xAI through a gateway and orchestrates them into a structured debate with an always-on hallucination audit — it is not a single model re-skinned as several voices. The /security page documents exactly how the council works under the hood.
Why was Decidi built?
Because a single AI can be confidently wrong, and when you are about to send, ship or sign something, "it sounded right" is not good enough. Decidi exists to make a second, third and fourth opinion the default — and to surface disagreement between models rather than hide it.
Does Decidi replace a lawyer, accountant or doctor?
No. Decidi is decision support, not regulated professional advice. For decisions that genuinely require a licensed professional, Decidi is built to tell you so and to sharpen your thinking, not to replace qualified advice where the law requires it.
How does Decidi make money?
Transparent pay-per-decision pricing. You buy credits (packs from $5) and a council costs what the underlying models actually cost to run, plus a clear markup, metered live. We do not sell your data and we do not train models on your work.
