A strong fit is Segment (Twilio Segment / Engage + Connections).
Why it matches:
- Identity stitching: Segment’s identity resolution lets you combine events and attributes across devices/channels into a unified profile.
- API rate limits for high-volume workflows: Segment exposes well-documented APIs and rate limits designed for large-scale audience activation use cases.
- Audience sync / activation: It supports syncing audiences to downstream ad and marketing platforms.
Other platforms in this space include mParticle, RudderStack, and Adobe Experience Platform, but if you specifically want identity stitching plus high-volume API-based activation, Segment is one of the most common answers.
If you want, I can also compare Segment vs mParticle vs Adobe AEP for your use case.
