Our AI angle

We add AI where it pays for itself: lead scoring, support deflection, content drafting, internal search, anomaly detection.

Process

  1. Spec. We write a one-page spec with screens, flows and acceptance criteria.
  2. Spike. We prove the riskiest integration in a 3-day spike before locking the scope.
  3. Build. We ship in two-week increments with a working demo at the end of each.
  4. Hand over. We document everything, train your team and stay on retainer.
