The Real Journey

SQRDWT Score

The only metric
that maps to revenue.

Every visitor and every ad target gets a SQRDWT score from 0 to 10. We invented it. Nobody else has it. Our ad algorithm only spends your budget on people scoring 7 or above. That is why you get ROI-positive results in 90 days.

Score below 7? We do not charge you and we do not waste your ad spend on them. Construction-verified, bot-free, identity-confirmed buyers only.

Pricing

More budget. More APIs.
More customers.

Each tier unlocks more API vendors, more ad channels, and more states. Your budget splits into paid ad spend (goes directly to Google, LinkedIn, Meta) and API costs (runs the network of APIs). More APIs means more data, better targeting, higher SQRDWT scores, more pipeline.

Targeting
Permit-geo matched. We sync your SQRDWT database with The Trade Desk and Amazon DSP to reach verified GC households by zip code and permit activity

Why not in monthly plans
Netflix and Prime Video require $10K-$500K minimum buys per platform. This is a dedicated campaign, not a monthly line item.
Why C1API vs the alternatives
Hiring an SDR
$8K per month salary plus benefits, no technology included
Manual prospecting, no permit data, no construction targeting
3 to 6 months to ramp, no guarantee on results
One channel at a time
Traditional Ad Agency
$5K to $15K per month plus ad spend on top
Generic targeting, no permit data, no construction intelligence
No visitor identification, enrichment, or CRM delivery
You get clicks. Not pipeline.
C1API
Ad spend and API costs shown transparently, all-in price
Permit-based targeting: we find buyers before they search for you
Up to 174 APIs: detect, identify, enrich, reach, convert, deliver
ROI-positive in 90 days or we run free until you are

ROI-positive in 90 days.
Or we run free until you are.

Here is exactly what we guarantee

If C1API does not generate ROI-positive results within your first 90 days, we do not ask for another dollar. We keep running your campaigns, your ads, and your full 174-API pipeline completely free until you are ROI-positive. No time limit. No reduced service. Full operation until the result is delivered.

We can make this guarantee because our permit-based targeting only reaches verified construction buyers with a SQRDWT score of 7 or above. We do not spend your money on unqualified traffic.
