What is sizeless?

Sizeless is an AI-powered platform that turns real-world environments into accurate 3D digital models, mainly for construction, infrastructure, and property teams. Instead of manual measurements or 2D plans, users can simply capture a site using a smartphone, and the system converts it into a detailed “digital twin” for documentation, analysis, and decision-making. It helps teams track assets, reduce errors, and make faster, data-driven decisions by giving a clear, visual understanding of complex physical spaces.

Designed around the philosophy of instant, audit-proof 3D as-built documentation directly from smartphone video, sizeless eliminates construction bottlenecks in civil engineering, utility installations, and house connection projects. Instead of pausing backfilling while waiting days for specialized surveying crews, field technicians capture open trenches using an iPhone Pro, allowing excavations to be backfilled immediately while AI algorithms extract centimetre-accurate spatial models and CAD revision plans within hours.

• Platform Role: AI Reality Capture Engine, Civil Infrastructure Digital Twin & Automated CAD/BIM Surveying Platform
• Founding & Leadership: Cornelius von Einem (Co-Founder & CTO), Julius (Co-Founder & CEO), and Roger de Belsunce (Co-Founder) — alumni of ETH Zurich, UC Berkeley, and Cambridge; Y Combinator S23
• Core Deliverables: Centimetre-accurate 3D point clouds, 2D CAD as-built revision plans (DWG, DXF), BIM models (IFC, RVT), and seamless GIS integrations

Use Cases:

• Surveying open utility trenches, pipe routes, and house connections (district heating, gas, water, telecom, fiber optic) prior to backfilling
• Creating audit-proof revision documentation and 2D CAD plans (DWG/DXF) to accelerate municipal compliance and contractor billing
• Capturing indoor basement entries and underground house utilities where satellite GPS signals are unavailable
• Documenting third-party utilities and identifying spatial routing clashes or construction deviations before trenches are sealed
• Generating structured BIM and 3D spatial data layers for building renovation, asset documentation, and facility management

Technology:

• Proprietary photogrammetry and neural reconstruction algorithms developed at ETH Zurich, achieving consistent sub-centimetre precision
• LiDAR and camera sensor fusion on iOS devices (iPhone Pro models) enabling robust spatial reconstruction without external reference markers
• Cloud-accelerated sizeless Insight Engine processing video data into dense 3D point clouds and automated geometric pipe extractions
• Enterprise-grade security framework where customer visual data is strictly protected and never used to train third-party public AI models

Target Users:

• Civil engineering firms and pipeline construction contractors looking to avoid excavation project downtime
• Municipal network operators and utility providers (district heating, power, telecommunications, water infrastructure)
• Surveyors and GIS managers needing rapid CAD as-built drafts without scheduling redundant on-site visits
• Energy consultants, general contractors, and facility managers managing property documentation and serial renovations

Acquisition: Specialized civil engineering AI reality capture platform

What are the key features of sizeless?

sizeless key platform features are

• Smartphone Video Capture: Field workers record short walk-through videos of excavations with an iPhone Pro—no bulky laser scanners or tachymeters required.
• Centimetre-Accurate 3D Point Clouds: Reconstructs open excavations into dense, high-resolution point clouds capturing surface details, utility pipes, and fittings.
• Automated 2D CAD Plans (DWG/DXF): Automatically generates compliant, revision-ready as-built drawings compatible with AutoCAD and standard CAD suites.
• GPS-Free Underground Mapping: Operates reliably in basements, dense urban canyons, and subterranean connection points where satellite navigation fails.
• Immediate Trench Backfilling: Eliminates site idle time by enabling crews to backfill immediately following video capture, cutting project lead times by weeks.
• GIS & BIM Integration: Seamlessly exports spatial coordinates, geometry, and digital twins directly into municipal GIS repositories and IFC/RVT formats.
• Audit-Proof 3D Evidence: Stores permanent digital records of subterranean installations to verify compliance and resolve subcontractor dispute claims.

How much does sizeless cost?

sizeless operates on an enterprise custom pricing model based on project scope, recorded square meterage, and organizational data volume.

Pricing Overview:

• Pilot & In-Person Demo: Prospective enterprise clients, utility operators, and engineering firms can request an in-person demonstration and run custom pilot captures.
• Volume & Project Licensing: Custom enterprise contracts tailored to active construction volume, linear trench meters, processing speed turnaround (e.g., 48h to 72h delivery SLA), and GIS integration requirements.

Disclaimer: Pricing varies based on capture volume (e.g., linear trench distance or square footage recorded) and CAD/BIM extraction requirements. Contact info@sizeless.co or visit sizeless.co/en to request an enterprise quotation.

Who should use sizeless?

sizeless is designed for civil engineering and utility infrastructure professionals, including

What are the pros and cons of sizeless?

What are the pros of sizeless?

• Allows immediate excavation backfilling without waiting for separate surveying appointments
• Runs directly on standard iPhone Pro hardware, eliminating tens of thousands in specialized surveying equipment
• Produces standardized, revision-compliant 2D CAD files (DWG/DXF) alongside 3D point clouds
• Works underground and in basements where GPS positioning is completely blocked
• Centimetre-level precision verified by computer vision research originating from ETH Zurich

What are the cons of sizeless?

• Field capture currently prioritizes iOS devices equipped with LiDAR (iPhone Pro models)
• Processing and final CAD/BIM model delivery can require 48 to 72 hours per large dataset
• Pricing is custom and requires an enterprise consultation rather than self-serve self-checkout

Why should you choose sizeless?

In traditional civil engineering and utility construction, open trenches must remain unburied for days or weeks while waiting for certified surveying teams to measure coordinates, causing street closures, safety hazards, and stalled cash flow. sizeless completely redesigns this process. By allowing any on-site technician to record a 60-second smartphone video, sizeless enables crews to backfill immediately while generating certified 3D point clouds, GIS-ready digital twins, and CAD as-built plans in parallel.

• Backfill excavations immediately after capturing smartphone video
• Receive industry-standard 2D CAD plans (DWG/DXF) and 3D models within 48 to 72 hours
• Document building entries and underground infrastructure accurately without GPS signals
• Integrate as-built spatial layers directly into existing enterprise GIS and CAD systems

How does sizeless compare to competitors?

While Matterport focuses primarily on real estate virtual walkthroughs and Pix4D provides generalized photogrammetry for drone mappers, sizeless is purpose-built for civil engineering trenches, utility house connections, and automated CAD revision plans.
