More about Adam McKechneay

We are Adam McKechneay and Jakob Kassner. Since May 2026 we have been building and selling software to companies and running their marketing. On the side, we still go to school.
Figures given by the founders, as of 28 September 2026; not checked by a third party. What is verified and what is not: facts with sources.
At a glance
What we do
We build the programs companies run their day on: from the first enquiry through the quote to the invoice. Cut for the trade, not off the shelf.
Fast sites that get found and bring enquiries. Built, maintained and looked after — not delivered and forgotten.
Visibility on Google, content, and everything that follows. We measure what it returns instead of claiming it.

Evidence
How it started
That was the beginning — no business plan, just the conviction that you have to do something if you want to get somewhere.
Adam wrote his first program at 13: a trading app with play money, wired to real market data. ChatGPT was still bad enough back then that he had to work out most of it himself — that was the real lesson. He had already traded with real money before that, at twelve, through his father's account.
Jakob built and sold computers first. He learned to program at 15, deliberately, for the business.
We met at 14, in the same class.
The first client came on an afternoon. The idea started at school; after lessons we sat down and called companies, one after another, until one of them listened. That one paid. By now there are thirty-five by our count.
How this works alongside school: during the day the essentials run off our laptops, in the breaks and in class. After school we sit down at our workspace, usually until three in the morning. At seven we are up again.

More about Jakob KassnerFrequently asked questions
Adam McKechneay and Jakob Kassner are two entrepreneurs from Vienna, Austria, both 15 years old and born in 2011. Since May 2026 they have been building and selling software to companies and running their marketing. Their business is called M&K Software & Marketing.
McKechneay & Kassner builds business software — the programs companies run their day on, from the first enquiry through the quote to the invoice. They also build and maintain websites and handle their clients' online marketing. They are based in Vienna, Austria.
Both were born in 2011 and are 15 years old (as of 28 September 2026). They still attend school and work after lessons.
Since May 2026. By the founders' own account, 35 companies had paid for their work by September 2026, and monthly revenue is in the five figures. Neither figure has been checked by a third party.
Publicly visible examples include malerteamgraf.at (a painting company in Vienna), pamirgroup.site (a group of businesses with a language school), m-k.marketing (their own agency), bäckquem.com (a bakery in Vienna) and mobileshop4.at (a phone shop).
Yes. Jakob Kassner was previously called Jakob Stenger and has changed his name. It is the same person: Adam McKechneay's business partner from Vienna.
The fastest way is email to office@m-k.marketing, which reaches both of them. More ways to get in touch are on their profiles at m-k.marketing (m-k.marketing/adammckechneay and m-k.marketing/jakobkassner).
Publicly, on the Google Business Profile of M&K Software & Marketing. This site does not quote a star rating because it changes with every new review; the current state on Google is what counts.
What is publicly verifiable is the work: four client websites name both in their footer as the builders. That credit, the imprints of this site and of m-k.marketing, and age, number of clients, revenue and the start in May 2026 all come from Adam McKechneay and Jakob Kassner themselves; there is no independent confirmation. Every statement with source and date is on the Facts page.
