Claremont McKenna College
400+ hours reviewing Civil Engineering documents during internship. Research at CalTech (Applied Physics) and Vanderbilt Medical School. Led Governor Gray Davis's housing policy research at the Rose Institute. Brings deep technical rigor and domain context to Lintel's contradiction detection and administrative agent workflows.
Jathan and Ibrahim have been collaborating since high school. They won the VEX Robotics State Championship together and were a top 5 U.S. team, were debate partners, and research collaborators on a 180+ page economics paper.
The Problem
We spoke with 50+ construction and engineering professionals about the top causes of cost overruns. The same pain points emerged.
Project scopes are often missing key details and leave trade responsibilities open to interpretation. Teams lose time resolving preventable scope disputes, change orders, and rework.
Drawings, specs, and schedules drift out of sync as revisions stack up. Those conflicts reach the field, triggering RFIs, coordination churn, and costly schedule slips.
Code and permitting issues often sit undetected from design through preconstruction. When they surface at review or inspection, teams absorb delays, redesign cycles, and potential fines.
The Solution
Lintel's AI continuously scans your entire project document set, detecting contradictions and compliance risks — with citations for instant verification. Administrative agents speed up submittal drafting, compliance reports, RFI management, and addendum tracking, dramatically cutting administrative time and costs.
Find contradictions across drawings, specs, and schedules automatically — no manual cross-referencing.
Every issue is backed by precise references to source pages and sections for instant verification.
Administrative agents speed up submittal and compliance report drafting, RFI management, and addendum tracking — all with deep understanding of your project's documents. Export directly to Procore and more.
How It Works
Upload or connect your entire project document set from cloud or local storage.
AI parses drawings, specs, and schedules in real-time for contradictions and compliance risks.
Issues are ranked by severity and confidence to focus team attention on highest-impact risks.
Every issue includes precise citations to source pages and sections for instant verification.
Generate issue logs and RFI-ready packets with context for seamless workflow integration.
Product
AI-powered scanning identifies contradictions across drawings, specs, and schedules in real-time — no manual cross-checking.
Administrative agents handle RFI management, submittal drafting, compliance reports, and addendum tracking. With deep understanding of your project documents, they dramatically reduce administrative time and costs.
Every issue comes with pinpointed evidence from source documents, making verification instant and auditable.
Ask questions across your entire construction document set and get instant answers with citations. Agents understand your project context to deliver accurate, actionable insights.
Market Opportunity
Construction management software is a $10.6B market in 2025, growing to $11.6B in 2026. U.S. construction spend hit $2.15T in 2024.
U.S. nonresidential teams working on complex projects — where RFI volume and documentation complexity are highest.
ENR Top 400 contractors and mid-to-large builders already adopting workflow technology. Buyers are VP Precon, Ops, and Project Execs.

Competitive Landscape
Existing tools manage workflows, but they still rely on manual admin effort for RFIs, submittals, and compliance reporting. Lintel combines contradiction detection with administrative agents that materially reduce both cycle time and processing cost.
Procore · Bluebeam · PlanGrid · BuilderTrend
Manage workflows but lack systematic contradiction detection
Manual review is slow, inconsistent, and doesn't scale
Admin teams still draft RFIs, submittals, and compliance reports largely by hand
No agent-driven workflow that consistently lowers admin hours and RFI processing cost
Purpose-built for contradiction detection
Cross-document contradiction and scope gap detection
Evidence-based citations with source page references
Administrative agents automate RFI management, submittal drafting, compliance reports, and addendum tracking
Faster admin cycles and lower processing cost with auditable, construction-specific outputs
The Ask
We're seeking pre-seed funding and strategic support to bring Lintel to thousands of contractors — helping them build homes, offices, and apartments faster and more affordably.
