C1API uses permit databases, contractor intelligence, and 174 APIs to find real construction buyers, bring them to your site through targeted ads, and convert them into pipeline automatically. You show up to the meeting.
This is not a demo. This is exactly how C1API works. A permit gets filed. We find the contractor. We run targeted ads. They land on your site. We convert them to a booked meeting.
Phase 1 brings qualified buyers to you using construction data. Phase 2 converts them automatically. All wired together.
This is the full C1API network. Construction data feeds the targeting. Ad platforms bring qualified traffic. Detection, identity, enrichment, and delivery run automatically on every visitor.
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.
Six criteria, scored 0 to 10. Our ad algorithm never spends a dollar on anyone below 7. Nobody else has this score. Here is every letter: what it measures, why it matters, and the APIs that power it.
From the first permit filed to closed deal attribution - every layer is automated, orchestrated by CLLM, and connected to the next.
The moment a permit is filed, four dedicated intelligence APIs fire in parallel. A contact is found, enriched, and an AI voice agent calls them within 60 seconds. No human needed.
ElevenLabs builds a construction-trusting voice persona per state. Vapi handles the call with ultra-low latency. No answer means voicemail plus email sequence. Meeting booked to CRM. Zero human clicks from permit to booked call.
When a construction lender approves a draw or an inspection passes, a project crossed a milestone. Materials need ordering. Subs need paying. Built and Sitewire feed C1API these signals in real time.
$721B/yr in the top 10 states alone. Construction GDP, Q4 2025 annualized. C1API covers all 50 — permit data, license APIs, and contractor databases per state.

One construction project has 6 decision-makers: Owner, Developer, Architect, MEP Engineer, Structural Engineer, and GC. C1API identifies the 1 visitor via Knock2, then Salesmotion and Databar.ai map the full buying committee and launch parallel outreach to all 6 within 24 hours.
Federal + state + local government construction is $500B+/yr, publicly announced, and free to target via SAM.gov API. Zero relationship required to bid. Recurring every year. C1API monitors SAM.gov, GovCon API, DemandStar, and PlanetBids continuously. When a GC wins a $10M school project, C1API immediately targets 15 to 20 subcontractors needed.
Permit fires, CLLM reads the attached PDF drawing, and Bedrock.cv + Kreo API extract exact material quantities: 4,200 SF of spray foam, 3 RTU units, 12,000 LF of copper pipe. C1API then targets the right material suppliers with exact specs before any RFQ is issued. Nobody else on Earth does this.
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.
The only construction sales firm running permit-targeted ads on Netflix, Prime Video, Hulu, and Peacock. We use your SQRDWT database to geo-target streaming audiences by permit activity. Your brand reaches GC owners at home, in prime time, on the platforms they actually watch.
We didn't prompt a general AI for construction. We built construction's AI from scratch. CLLM is a continuously trained foundation model fed by every permit, bid, license, contractor signal, and material price in the United States. Updated every 4 hours, connected to the live internet, wired directly into every decision C1API makes.
When a GC files a $2.4M commercial permit in Austin at 2:14 PM, CLLM reads it, identifies the contractor, fires the right combination of 174 integrated APIs to build a complete contact profile, scores them with SQRDWT, and routes them into your ad pipeline. Before they even walk off the job site.
General AI companies treat construction as a vertical. We treat it as the domain. CLLM will become the most accurate predictor of construction revenue outcomes in the world. Not because we're bigger. Because we're specific. C1API is both an API platform and a frontier research lab. CLLM 5.1 is the foundation of what we intend to be the Bloomberg Terminal for construction intelligence.
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.
No setup fee. Live in 48 hours. Cancel anytime before day 90.
