We scored 238 Napa IT consultants on nine factors, weighted as shown. An IT firm is ranked when its service is confirmed and it has 3 or more Google reviews or a claimed profile. An IT firm with no Google reviews scores zero on rating, review volume and recency. Other unknown factors are left out, not counted as zero. Scores last refreshed November 9, 2026.
Paid placement never changes a rank or score. Sponsored businesses are paid, labelled, limited to 3 and shown above the ranking, outside it.
