My success is thanks to you.

おかげ ('thanks, owing to') is the positive counterpart to せい ('because of, fault of'). The pattern X のおかげだ ('it is thanks to X') is the standard way to express gratitude for a positive outcome. Japanese distinguishes positive attribution (おかげ) from negative (せい) — a subtle but culturally important framing.
