We deploy on a trusted stack
Products - Software that compounds specialist work.
Each product is its own company under the FSK brand.

Personal life management — finances, goals, habits — for people and couples.
Practice - We deploy AI inside your company.
One accountable team. Humans in the loop.
Software we deploy
fsk.tax — our own platform — plus the best-fit stack for yours: Vanta, xOne, Microsoft, Google, Qlik, and more. Chosen for your problem, not ours.
AI that runs continuously
Production agents, monitoring, and generative insights working around the clock — not a one-off project.
Your team, enabled
We train your CFO, CISO, and COO to run the system. We do not replace them.
FSK on escalation
Specialist judgement engaged for the moment it is needed — not on retainer.

Not pure SaaS. Not pure consulting. Every engagement combines three delivery modes.
