<p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">Hey G2 agency folks, a question for the people who run client dollars through these platforms: which CTV advertising platforms actually keep agencies after onboarding? Retention is the honest metric, since every platform can win the pitch. Researching<a class="a a--md" elv="true" href="https://www.g2.com/categories/connected-tv-ctv-advertising-platforms"> </a><a class="a a--md" elv="true" href="https://www.g2.com/categories/connected-tv-ctv-advertising-platforms">Connected TV (CTV) advertising platforms</a>, the split that organizes the category is managed service versus self-serve, and what retains an agency differs by lane:</p><ul>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/stackadapt/reviews"><strong>StackAdapt</strong></a>: the agency staple here, with 550+ of its G2 reviews coming from agency seats. Agency reviewers describe monthly optimization reviews with their account teams, so the relationship does not go quiet after onboarding, which is the managed service retention play in action.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/the-trade-desk/reviews"><strong>The Trade Desk</strong></a>: the self-serve lane at its most institutional. Retention comes from depth: agencies invest in training and certification, and that accumulated expertise is what keeps seats renewed year over year.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/simpli-fi/reviews"><strong>Simpli.fi</strong></a>: built around agencies and local media companies from the start, with managed service and white-label options, so it retains by becoming part of the agency's own client offering.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/mntn-performance-tv/reviews"><strong>MNTN Performance TV</strong></a>: the brand-direct self-serve play that agencies also run for performance clients, where retention rests on CTV results reading like the search and social reporting clients already trust.</li>

&lt;p&gt;Managed service vs self-serve is the real fork in the road here, not the platform names. StackAdapt keeps agencies because someone&#39;s actively optimizing your account, but that also means you&#39;re paying for a relationship, not just software. Self-serve saves money short term but only if your team actually has the expertise to run it well, otherwise you&#39;re just quietly underperforming.&lt;/p&gt;
