Batuhan Emre TAMAM: the founder building OXS Corp, Kointage, Caildus and Earvance

Batuhan Emre TAMAM is the Istanbul-based founder and CEO of OXS Corp, a technology company registered in Wyoming, United States. Under OXS Corp he is building three products, each with its own brand: Kointage, an AI-powered platform for financial research and market intelligence; Caildus, an AI development companion that writes, reviews and refactors code; and Earvance, an agricultural intelligence concept for greenhouses. Together they make up the OXS ecosystem, presented under the name OXS Holdings.

This article sets out who he is, what he is building and how he thinks about it — drawing on his own words and on the public websites of the companies themselves.

One conviction, three companies

Batuhan Emre TAMAM describes the starting point of OXS in a single sentence:

I started OXS with one conviction: the technology that matters is built by people willing to stay with it for a long time.

That sentence explains a lot about how the ecosystem is organized. OXS Corp is not built around one product or one market. It is built around a way of working — choosing problems worth years of attention, and then staying with them. Kointage, Caildus and Earvance are the first results of that approach, and they deliberately sit in very different fields: finance, software development and agriculture.

In his note on the founder page, he puts it this way: Kointage, Caildus and Earvance are "different answers to the same question: what can technology do better, for the people who rely on it?" Each has its own identity, and each is held to the same standard — "useful, honest, carefully made."

Twenty, and from Istanbul

When he wrote his founder's note on this website in October 2026, Batuhan Emre TAMAM was twenty years old. He doesn't treat that, or the city he comes from, as a constraint:

I'm twenty, and I'm from Istanbul. I don't see either as a limitation. If anything, they are reasons to think further ahead — to build companies that will still be relevant long after this decade is over.

The setup is international from the start. OXS Corp is registered in the United States, in Wyoming, while its founder works from Istanbul — and the products are made for a global audience: their websites are in English, and they address markets and users around the world.

What he is building

OXS Corp — the company behind the products

OXS Corp is where the technology takes shape. It develops digital products and software systems, explores where emerging technology — artificial intelligence in particular — can be applied usefully, and turns promising products into ventures with identities of their own. Its name appears on each product's own website: Kointage carries "OXS Corp." beside its logo, Caildus's footer reads "© 2026 Caildus · OXS Corp.", and Earvance introduces itself as "agricultural intelligence by OXS Corp."

Kointage — financial intelligence

Kointage is an AI-powered tool for financial research and market intelligence. It is designed to help people analyze stocks and their charts, follow the financial news that moves markets, and understand their portfolios. Kointage is a research and analysis product, not an investment adviser. More in What is Kointage?

Caildus — AI for software development

Caildus is an AI development companion. A developer connects a GitHub repository, an AI agent analyzes the codebase, and suggestions arrive as visual diffs that can be reviewed and applied with one click. Agents can be extended through MCP integrations and run in parallel. Kointage's own website carries a "Powered by Caildus" credit — one of the clearest examples of the companies working together.

Earvance — intelligence for the physical world

Earvance explores agricultural intelligence for greenhouses. It is presented openly as a concept preview: its dashboard runs on simulated data and hardware specifications are still to be confirmed. Its design keeps the grower in charge — guidance cites its evidence, and nothing is irrigated without an operator's approval. More in Earvance: an agricultural intelligence concept for greenhouses

How he approaches building

Across the companies, a few principles recur. They are written down on the philosophy page and explored further in Building for the long term.

• Start with the problem, not the technique. A product earns its place by solving a problem that is real. Artificial intelligence is used where it helps — reading a chart, reviewing a diff, explaining a sensor reading — not as decoration.
• Independence without distance. Each company keeps its own brand, product and pace. What they share is a standard of quality and honesty.
• Show rather than claim. A working product, carefully made, says more than an announcement. That is why Earvance is labelled a concept rather than presented as finished, and why Kointage states plainly that it doesn't give investment advice.
• Think in years. Long-term thinking, as he frames it, is not slowness; it is the discipline of choosing relevance over noise and value over attention.

His note ends with an invitation rather than a pitch:

We are not interested in noise. We are interested in work that lasts. If that is how you think too, I would like to hear from you.
