Most businesses don't need
more software.
They need the software they already have to tell them the truth, on time, in one place. They need somebody to chase the receivables, fill the pipeline, and track what's slipping, without another hire who leaves in a year.
That is what Kastelon does. We run a small, sharp team that drops into your business, stands up four products that matter, and reports to your CEO every week.
How we decide, when it's hard.
Managed, not sold
We do the work. You do not log in, configure, or administer. If a thing is broken, that is our name next to it.
Earn the next product
You start with one. When the numbers move, you take the next. Nothing gets bundled into a contract it cannot justify.
Small numbers, kept
We promise one metric per product and report on it every week. No vanity charts. If a metric fails, we say so first.
Your voice, our hands
Every reminder, every cold email, every report carries your tone, your words, your brand. We are invisible by design.
Three partners. A short bench.
Mark Sebastian
Runs revenue partnerships and capital relationships. The relationship architect who opens the first door.
Nicholas Toh
Builds the engine. Dashboards, automations, integrations. The reason clients are live in fourteen days.
Mohan Louis
Runs the client lifecycle end to end. The voice on the first call and the one that stays after.
