02 — Approach

How we work

  1. 01

    We run what we ship.

    The people who write the code also host it, answer the support emails and send the invoices. There are no agencies and no hand-offs.

  2. 02

    Your data stays where you put it.

    GetBlitz and Semantik both run on your own infrastructure if you want. Privacy is designed in from the first commit, not added before launch.

  3. 03

    Narrow beats broad.

    Each product serves one audience with one job. Going deep on one problem beats being shallow on ten.
