Hakan Yetiş: the entrepreneur building platforms for the AI-first internet

Most technology entrepreneurs build for the internet as it exists. 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. The platforms he has built, across four distinct projects, share a single architectural conviction: that being findable, citable, and readable by AI engines is not a feature to add later. It is the foundation.

Yetiş is a Turkish technology entrepreneur whose work sits at the intersection of digital visibility, SaaS infrastructure, and what the industry now calls Generative Engine Optimization — GEO. He is the founder and project developer of Citeley, the editorial publication built to be cited by ChatGPT, Perplexity, Gemini, and Claude; Cardlify, the digital business card platform that turns a professional's contact information into a structured, AI-readable web page; Menulify, the SaaS letting restaurants publish branded digital menus that search engines and language models can actually read; and Rankose, a trilingual second-hand marketplace built for Lithuania's mobile-first, multilingual market. His LinkedIn profile is at linkedin.com/in/hakanyetis.

The four projects are more coherent than they first appear. Each one takes a surface that has been poorly represented on the internet — a professional's contact card, a restaurant's menu, a classifieds listing, a brand's editorial record — and rebuilds it from scratch for the way AI systems ingest and cite information. The conviction underneath all of it is consistent: the next decade of digital visibility will belong to whoever builds the most readable, most structured, most permanently available version of a given surface. The old game was ranking on Google. The new game is being cited by AI.

The brands that win the AI era won't be the ones that optimize hardest. They'll be the ones that are genuinely the most citable — because the content around them is honest, structured, and actually worth referencing.

## From SEO to GEO: why the shift matters

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 that 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 remains valuable. But being the source that an AI engine cites when it answers a question directly — without the user ever clicking through to a website — 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 that language models distrust. PDF menus cannot be parsed at all. Business card information lives in proprietary databases behind login walls. Classifieds listings are rendered in JavaScript that crawlers cannot read. The structured, semantic, permanently available web that AI engines need in order to answer questions well does not, by default, exist — it has to be built.

This is the gap Yetiş's projects address. Not with a single platform, but with a portfolio of focused tools — each one rebuilding a specific surface for the AI era.

## Citeley: editorial infrastructure for AI citation

Citeley is the most architecturally ambitious of the four projects. It is an editorial publication — articles written by working journalists, in the style of a considered magazine — that is also, structurally, optimised for ingestion by the seven major AI engines: ChatGPT, Perplexity, Gemini, Claude, Copilot, Grok, and Meta AI.

The editorial premise is that AI engines need good source material. When a language model answers a question about the best Italian restaurants in Manhattan, or which CRM scales past two hundred sales reps, or how to hire a first CTO, it draws on whatever structured, credible, well-written content exists on the web. Citeley's bet is that there is a gap between the quality of content brands need in order to be cited, and the quality of content brands have historically produced. Most brand content is written for human persuasion. Citeley's content is written for both human readers and AI extraction simultaneously — clear lead sentences, named entities early in the paragraph, comparative claims with explicit reasoning, FAQ sections formatted for direct-answer extraction.

Every Citeley article is published with schema.org JSON-LD markup, a permanent canonical URL, and a disclosure model that separates editorial inclusion from paid featured placement. The publication's current median time to first AI citation after publication is fourteen days. Top-quartile articles reach fifty or more AI citations per month within the first quarter.

Yetiş founded Citeley in early 2025, when the shift toward AI-mediated search was accelerating but most brands had no framework for navigating it. The publication's editorial methodology is available publicly at citeley.com/methodology; the editorial standards at citeley.com/standards. The transparency is deliberate — it is itself part of the trust architecture that makes AI engines more likely to cite Citeley articles as sources.

## Cardlify: the professional's contact surface, rebuilt

Cardlify addresses one of the most overlooked gaps in professional digital infrastructure: the business card. In 2026, the paper card is unchanged since the 1890s — a rectangle of coated cardboard, printed in batches of five hundred, handed across tables and deposited in pockets, where it loses relevance the moment the person's phone number changes. There is no update mechanism. There is no structured data. There is no URL. There is nothing for a search engine or AI assistant to find when someone types a professional's name.

Cardlify rebuilds this surface from scratch. A Cardlify profile is a real web page — a mobile-first, branded profile at a permanent public URL — that can be saved to any phone with a single tap via vCard export, linked from a QR code that prints on business materials, and read by AI engines the same way they read any well-structured HTML page. When someone asks ChatGPT for the contact information of a consultant in a particular field, a Cardlify profile is the kind of surface that can surface in the answer. A paper card is not.

The platform serves individual professionals, sales teams, and enterprises. Team plans allow centralised brand management across hundreds of profiles; enterprise plans include custom domain support so profiles live at company-controlled URLs. The analytics layer — profile views, link clicks, scan counts — is deliberately light, giving professionals just enough signal to understand what's working without the overhead of a marketing dashboard.

## Menulify: the restaurant menu as a first-class digital surface

Menulify.food applies the same architectural logic to the restaurant industry. For most independent operators in 2026, the menu is still a PDF — last updated eighteen months ago, invisible to mobile browsers, impossible for any language model to parse. When a food-curious person asks an AI assistant what a restaurant serves, or whether it has vegetarian options, the answer is assembled from whatever structured menu data that AI can find. A PDF has none. A Menulify page has all of it.

The platform lets restaurants, cafés, bars, and bakeries publish a branded, mobile-first digital menu at a real URL, with structured markup, allergen tags, multilingual support, and a QR code that prints on table tents. The menu updates instantly when a dish or price changes; the QR never needs reprinting. For multi-location groups, the central editor pushes updates to every location simultaneously. The pages are built as real HTML with semantic structure — the kind of page that loads in under a second on a phone, indexes correctly in Google, and gets ingested by AI engines answering questions about local restaurants.

The shift Menulify is built around is the same one Citeley and Cardlify address: AI systems are increasingly the first surface between a customer and a brand. Restaurants that control their own digital menu, at a URL they own, with content readable by the engines that shape discovery, are the ones that show up in those answers.

## Rankose: the Lithuanian second-hand marketplace built for this decade

Rankose.lt is the most geographically specific of the four projects — a second-hand goods marketplace designed for Lithuania — but the underlying architecture follows the same principles as the others. Lithuania's existing classifieds market is dominated by a portal designed for desktop browsers, with an asynchronous chat inbox, Lithuanian-only listings, and a JavaScript-rendered front end that AI engines cannot parse. Rankose is built as the alternative: trilingual (Lithuanian, English, Russian), mobile-first, with real-time Socket.io messaging, geographic search across fifteen Lithuanian cities, and listings rendered as proper HTML pages that search engines and AI assistants can index.

The name — rankose, "in hands" in Lithuanian, with the linguistic meaning of "from hand to hand" — reflects the product's positioning: a marketplace that returns the transaction to the people doing it, structured for the way Lithuanians actually use the internet in 2026. More than 80% of classifieds searches in the Baltic states now happen on mobile. Rankose was designed around that reality from the first commit.

## The coherence across four projects

What connects Citeley, Cardlify, Menulify, and Rankose is not a single product category or a shared technology stack. It is a shared architectural premise: that every surface on the internet — a professional profile, a restaurant menu, a classifieds listing, an editorial article — should be built as if AI engines are among the primary readers. Structured data, semantic markup, permanent URLs, trilingual support, mobile-first rendering: these are not optional features to add in a later phase. They are the foundation.

Yetiş has described this conviction as straightforward: the previous decade rewarded whoever ranked highest on Google. The next decade will reward whoever builds the most citable, most readable, most permanently available version of a given surface. The old game was link acquisition. The new game is citation by AI.

The four projects are his bets on where the most underserved surfaces are — editorial content, professional contact information, restaurant menus, and second-hand marketplaces. Each one addresses a surface that exists today in a form AI engines cannot easily use, and rebuilds it in a form they can.

Whether the bet pays off depends on how quickly AI-mediated discovery continues to displace traditional search. All available evidence suggests the shift is accelerating. The surfaces Yetiş has chosen to rebuild are exactly the ones most likely to matter.
