Ad campaign failover and status monitoring for media buyers

The moment a media buyer realizes their ad management software has been silently broken for days is usually when they check performance and see a cliff in spend or impressions — not when the software tells them. By then, campaigns have been paused, budgets have gone unspent, and reporting is a mess. The gap isn't just detection; it's that when software fails, there's no independent layer watching whether campaigns are actually running as configured at the platform level.

The reason this gap persists is structural: ad management vendors have no incentive to tell you their own tool is down. When things break, their support queue fills up, and the buyer — often an agency or in-house performance team — has no independent signal. The vendor controls the status page, controls communication, and controls the timeline on fixes. Users here describe being non-functional for 'over 6 months' with no proactive communication. That's not a bug; that's a business model misalignment.

What's missing isn't a generic uptime monitor — those watch whether a URL returns a 200. What's needed is something that independently verifies campaign state at the platform API level: are bids being submitted? Are creatives serving? Are budgets being consumed at expected rates? A raw uptime check won't catch 'internal server errors for any function' that still return a page, or a campaign creation tool that's broken while the dashboard loads fine.

For an agency running campaigns across five clients, a week of broken software without detection means missed KPIs, client trust damage, and refund conversations. The need recurs every time a vendor pushes an update, every time API keys rotate, every time a platform changes its authentication. This isn't a one-time audit — it's a permanently needed watch layer that no ad management vendor will ever build credibly because it would expose their own failures.

What to build

Build a service that connects directly to Google, Meta, TikTok, and LinkedIn campaign APIs using the buyer's own credentials, checks every 15 minutes whether campaigns are active, bids are submitting, and spend is moving, and sends an alert with campaign-level detail the moment something diverges from expected state — independent of whatever ad management middleware sits in between.

Where to start

Start with Google Ads and Meta only, targeting boutique agencies who've already been burned by a middleware outage — they're actively looking for an independent check layer and will tolerate limited platform coverage if the core detection is reliable.

The hard part

Getting the first customer requires them to hand over API credentials to an unknown service on day one, before you've built any trust — you have to nail the credential security story and probably offer a self-hosted option before agencies will take the risk.
