Own your audience: First-party data is now local advertising's secret weapon

The Problem: The industry optimized for scale, not accessibility

Here’s the truth: local businesses have incredibly valuable first party data just like the world’s largest advertisers, but activating it at scale can be a challenge.

Your lists are there: loyal customers who spend, high-intent leads ready to convert, and the engaged browsers who haven't pulled the trigger yet. But traditional data onboarding was built for Fortune 500 budgets with high minimums, long timelines, and minimal flexibility for local advertisers. 

Madhive is changing that. We partnered with Deep Sync to bring first-party data activation to local CTV - fast, accessible, and built for businesses of any size.

Why first-party data is your most valuable asset

In a cookieless world, first-party data is data you can fully control and trust. It’s collected directly from real customer interactions - their purchases, their preferences, their real-world interactions with your business.

• Precision targeting: Reach people who already know you. Targeting with first-party data dramatically increases the likelihood of meaningful engagement.
• Smart prospecting: Build lookalike audiences that mirror your best customers. Find more high-value buyers without wasting impressions.
• Future-proofed and privacy-safe: Collected with user consent, it stays within  your ecosystem, ensuring transparency and control as privacy regulations evolve.
• Provable results: Close the loop between your CTV campaigns and actual business outcomes.

But here’s the catch: first-party data only matters if you can activate it. And until now, most SMBs didn’t have a solution designed for the unique challenges and opportunities of local.

Enhanced Onboarding: The local-first unlock

Deep Sync’s Enhanced Onboarding cuts the complexity. This integration makes first-party data activation simple, fast, and accessible – no enterprise budget required.

Think of it like this: you’ve had a turbocharged vehicle in your driveway, but you didn't have the keys. We just handed them to you.

Madhive has always been built for local-first. While other platforms set minimums that shut out small and mid-sized businesses, Deep Sync and Madhive’s collaboration removes those barriers entirely.

Here’s what you can now do with your customer data on CTV:

And it happens in under 24 hours. Upload your list, and your audience is live on Madhive - ready to activate across premium CTV inventory.
