Who builds Killion
Killion is built by Berkay Kolay, who founded Killion Labs Ltd and writes the simulation engine the product runs on. The research published on this site comes from that engine, and it is signed rather than issued anonymously by "the team".
We hold no financial planning or investment credential, and we do not claim one. What we bring is a specific, checkable capability: the ability to run a controlled experiment across thousands of simulated market lifetimes with the method stated and the runs reproducible. Where an established researcher has already answered a question, we cite them. How that work is produced and corrected is set out in our editorial policy.

What Killion is not
Killion is software. It is not a registered investment adviser, broker-dealer, financial planner or tax professional, and it does not give advice, recommend securities or manage money. Account access is read-only at the connection level, so it is not merely that we will not trade on your behalf — we cannot. That is covered in detail on the security page.
There are also things the product does not do yet, and we would rather you find them here than after paying. It does not model taxes, Roth conversions or RMDs. It has no shared household access for couples. Automatic bank linking is paused while we move to a new provider. SOC 2 Type II certification is on the roadmap and has not been completed.
Why we built it
Uncertainty about the financial future is one of the few things money does not fix. It does not care how much you earn, how much you have saved, or how successful you look on paper. Whether you are building a career, raising a family, or just trying to stay on top of your accounts, the same question lingers: what happens next, and will I be okay?
Most people do not struggle because they lack discipline. They struggle because they cannot clearly see what their decisions actually lead to. When the future stays blurry, it is easy to feel stuck or make choices based on hope instead of information. Once you can see the real range of what your future could look like, the weight shifts. The question stops being "will it work?" and becomes "which path makes the most sense for me?"
The first thing standing in the way is your own data. Modern financial life is scattered across a dozen places — banks, retirement accounts, brokerage accounts, equity grants and crypto. Nobody is built to pull all of that together by hand, and nobody should have to. You cannot plan a life you cannot see.
The second barrier is cost and access. Serious long-term financial modeling used to require expensive advisers or complex software that most people could not justify. If you were not already wealthy, getting clear answers about your future was either too expensive or too complicated. That is no longer a technical necessity. The kind of forward-looking analysis that helps people make better decisions can be delivered directly, at a price that makes sense for everyday life.
Killion exists to fix both problems. We connect the different parts of your financial life and run real simulations across years and decades — not generic projections, but personalised ranges based on your actual numbers. Unlike traditional wealth managers, we do not take a percentage of your assets, charge commissions or hide fees. Just a simple monthly price, and the arithmetic behind why that matters.
You stop guessing, and start knowing.
