Dependable software, built with care.

We design software to behave predictably, preserve data integrity, and remain maintainable over time.

What we build

Palacios Software Group is a founder-led software company.

Our focus is narrow on purpose: fewer products, built to last, with the difficult parts — data integrity, recovery, failure handling — treated as the work rather than as an afterthought.

What exists today

Yoslion Download is our first product, currently in development.

How we build

  1. Reliability before superficial speed
  2. Data integrity before convenience
  3. Explicit contracts instead of assumptions

These are design principles, not guarantees — they describe how decisions get made, and what gets refused.
