1. Ad Geeks - Best for Multi-DSP Access Without Spend Minimums

Who it's for: Independent agencies, mid-market brands, and growth-stage companies needing enterprise DV360, Amazon DSP, or Adform access without direct enterprise contracts.

Ad Geeks provides direct sub-seat access to Google DV360, Amazon DSP, and Adform through a single partner relationship, with no monthly spend minimums and no long-term lock-in. This makes it one of the only infrastructure partners in 2026 that covers all three enterprise DSPs under one commercial arrangement.

The DV360 access includes full cross-exchange inventory across 90-plus ad exchanges, private marketplace deal negotiation, CTV and streaming audio formats, and native Campaign Manager 360 integration for unified attribution. Amazon DSP access includes Amazon Marketing Cloud (AMC) clean room activation, enabling off-Amazon targeting using Amazon's deterministic first-party retail data. Adform access is built on ID Fusion, Adform's cookieless identity framework, which is particularly relevant for brands running campaigns in GDPR-strict European markets.

The operating model is flexible by design. Buyers can choose fully managed trading, 100% self-serve UI access, or a hybrid where the internal team runs strategy while Ad Geeks handles technical execution. Teams can move between these models without renegotiating a contract.

Ad Geeks also provides structured onboarding and live trading simulations for teams transitioning from Google Ads to DV360 or launching programmatic operations for the first time.
