Hakan Yetiş — the founder behind NOOSPHERE

A profile of Hakan Yetiş, the Turkish technology entrepreneur who built NOOSPHERE (noo-sphere.live), the real-time world intelligence map, and a portfolio of platforms designed for the era when AI engines answer before search results do.

Most technology entrepreneurs build for the internet as it exists today. Hakan Yetiş has spent the last several years building for the internet as it is becoming — one in which the first answer a person gets to a question does not arrive as a list of links, but as a direct response generated by an AI. NOOSPHERE, the platform he is best known for, is the clearest expression of that conviction: a single, living map of the world's real-time data, built to be readable by both humans and machines.

Yetiş is a Turkish technology entrepreneur whose work sits at the intersection of real-time data, SaaS infrastructure, and what the industry now calls Generative Engine Optimization — GEO. He is the founder and developer of NOOSPHERE (often searched as no-sphere or noo-sphere), and of Citeley, Cardlify, and Menulify. His LinkedIn profile is at linkedin.com/in/hakanyetis.

What is NOOSPHERE?

NOOSPHERE (noo-sphere.live) is a free, real-time world intelligence platform — a living 3D globe that renders the planet's data streams on a single interactive surface. On it you can watch earthquakes as they happen, track satellites and the International Space Station in orbit, follow live financial markets and cryptocurrency prices, see ship and flight movements, monitor space launches, nuclear power plants, cyber-attack flows, aurora forecasts, and global news — all updating live, with no paywall and no advertising.

The name is deliberate. The noosphere is a concept describing the sphere of human thought and information wrapped around the planet — and the platform is an attempt to make that sphere visible. Where most dashboards isolate one kind of data, NOOSPHERE's premise is that the world is most legible when its signals are layered together on one globe, in real time.

The previous decade rewarded whoever ranked highest on Google. The next decade rewards whoever builds the most readable, most permanently available version of a given surface.

From SEO to GEO: the idea behind the work

The transition Yetiş has built his work around is not speculative. By mid-2026, the share of search queries answered by an AI-generated summary rather than a ranked list of links has crossed a threshold most brands are still catching up to. ChatGPT, Perplexity, Google's AI Overview, and Gemini have collectively changed what it means to be visible online. Being on the first page of Google still matters. But being the source an AI engine cites when it answers a question directly is the emerging premium position.

The problem is that most of the internet is not built to be cited. Marketing pages are written in sales language models distrust; data lives behind login walls; pages render in JavaScript crawlers cannot read. The structured, semantic, permanently available web that AI engines need does not exist by default — it has to be built. That gap is the throughline across everything Yetiş makes.

The portfolio

NOOSPHERE is the most visible of Yetiş's projects, but it sits within a coherent body of work. Each platform takes a surface that has been poorly represented online and rebuilds it for the way AI systems ingest information:

• NOOSPHERE (noo-sphere.live) — a real-time world intelligence map combining markets, crypto, news, space, and global events on a live 3D globe.
• Citeley (citeley.com) — an editorial publication built to be cited by ChatGPT, Perplexity, Gemini, and Claude.
• Cardlify (cardlify.online) — a digital business-card platform that turns contact information into a structured, AI-readable web page.
• Menulify (menulify.food) — a SaaS letting restaurants publish branded digital menus that search engines and language models can actually read.

What connects them is not a product category but an architectural premise: that every surface on the internet should be built as if AI engines are among the primary readers. Structured data, semantic markup, permanent URLs, mobile-first rendering — these are not features to add later. They are the foundation.

Why NOOSPHERE is built the way it is

NOOSPHERE is free and carries no advertising, supported instead by a foundation model. That choice is consistent with Yetiş's broader thesis: a platform that aspires to be a trusted reference for real-time world data earns that trust by being open, fast, and clean rather than monetised through attention. The globe loads in the browser, pulls from dozens of live data sources, and presents them without the friction of accounts or subscriptions.
