Why Teams Switch from AdRoll to Synter

Platform Coverage

AdRoll covers display, Meta, and email. Synter covers Google Search, Meta, LinkedIn, TikTok, Reddit, Pinterest, Snapchat, Microsoft Ads, Amazon DSP, Spotify, X, and Taboola. Most B2B and performance teams need more than retargeting.

Autonomous Execution

AdRoll gives you a dashboard. Synter gives you an AI agent that executes. Instead of navigating UI to adjust bids or rotate creative, you tell the agent what you want and it acts — with a full audit trail of every change.

Predictable Pricing

AdRoll charges a percentage of ad spend. Synter charges flat monthly tiers. At $10K/month ad spend, AdRoll fees run $100–300/month and scale with your budget. Synter stays flat as spend grows.

AI Creative Generation

Synter includes AI image and video generation for ad creative. AdRoll has no creative generation — you bring your own assets. Synter agents can generate, test, and rotate creative across all platforms automatically.
