Drawer AI

AI-powered electrical takeoff and estimating software for commercial contractors

Austin, Texas-based SaaS platform built specifically for electrical contractors and estimators. Drawer AI applies AI to PDF electrical drawing sets to detect power devices and lighting fixtures, extract panel/lighting schedule data, and automatically route and size branch circuits, and offers a separate "BIM Wizard" feature that converts 2D PDF drawings into a coordinated 3D Revit model with routed conduits. Founded in 2021 by former electrical estimators, the company came out of stealth with a $5M seed round in October 2024 and reports 200+ electrical-contractor customers across the US and Canada.

$5M seed round (announced October 2024, led by Brick & Mortar Ventures with participation from Base10 Partners) - confirmed across the company's own press release, Crunchbase, PitchBook, Tracxn, and multiple trade-press reports. The internal research queue for this entry listed "$5.5M" total funding and "Precon50" as a backer; no evidence for either the $5.5M figure or a backer/investor named "Precon50" was found in any public source, so only the verified $5M seed is reported here. raisedGrowth Stage

Founded 2021 · 200+ electrical contractors across the US and Canada (company-stated); named customers include Starr Electric Company, WTC Electric, and Illuminico; launched publicly in October 2024 with 6 electrical contractors already on the platform

WHY IT EXISTS

Why This Tool Exists

The Problem

Electrical contractors and estimators manually count thousands of power devices and lighting fixtures across multi-sheet PDF drawing sets, then hand-route branch circuits and size wire - work that Drawer AI's own customer case study describes as consuming "multiple 15-hour days" per bid on a mid-size commercial project, with miscounts or missed devices carrying direct cost risk on fixed-price electrical bids.

The Solution

Drawer AI scans uploaded PDF electrical drawings to detect devices and lighting fixtures, reads panel and lighting schedules, automatically stitches multi-sheet drawings into one layout, and routes branch circuits with NEC-based wire sizing and voltage-drop derating - producing a marked-up PDF and an Excel quantity/conduit schedule that an estimator reviews and corrects before bidding. A separate BIM Wizard feature converts the same 2D PDF drawings into a coordinated, clash-checked 3D Revit model with routed conduits.

TRANSPARENCY

Data Transparency

Exactly what this tool uses and how

Input

What it needs

Required:Electrical PDF drawing sets (plan sheets, panel schedules, lighting schedules)

Optional:Project-specific routing/NEC standard preferences, Company-specific symbol library (Enterprise tier)

Formats:PDF

Output

What you get

Format:Marked-up PDF drawings plus an Excel-based quantity/conduit schedule; the BIM Wizard feature additionally outputs a native 3D Revit model

Fields:Device and lighting fixture counts/tags, Branch circuit routing paths and home runs, Wire sizing and voltage-drop derating calculations, Conduit schedule (Excel), 3D Revit model with routed conduits (BIM Wizard)

Algorithm

How it works

Model:Proprietary computer-vision / document-AI system (architecture not publicly disclosed); the company's privacy policy confirms use of AWS Bedrock, including Anthropic Claude models, though Drawer does not specify which product features rely on Claude versus in-house models

Accuracy:Company markets up to a 70-90% reduction in takeoff time (customer case study: Starr Electric Company analyzing 2,600+ fixtures and 3,400+ power devices); no independent accuracy/precision benchmark for device detection or routing correctness was found. The company states its AI output "is reviewed and validated before it is delivered" and that "accuracy improves as more projects are processed," stopping short of claiming a fixed detection-accuracy figure.

Privacy

How your data is protected

Retention:Per Drawer's published privacy policy: account data is retained while the account is active and deleted "within a reasonable timeframe" after account deletion. Customer Content (uploaded drawings and data derived from them) is "retained indefinitely by default" - soft deletion does not remove underlying data. Hard deletion is available only on written request to [email protected], though backup copies may persist up to one month. Usage/log data is retained approximately one month.

Training:Yes. Drawer's privacy policy states Customer Content - including uploaded drawings and data derived from them - is used to improve Drawer's AI systems (training, fine-tuning, evaluation, QA, debugging, feature development); authorized Drawer personnel/contractors may access Customer Content on a need-to-know basis. Enterprise customers can request exclusion from this use via a written agreement with [email protected].

Compliance:SOC 2 Type II - company states it is "working toward" certification as of this research (not yet certified); a compliance summary is described as available on request, No GDPR-specific compliance program described - the privacy policy is scoped to US/Canada operations, Named subprocessors with Customer Content access: AWS and AWS Bedrock/Anthropic; subprocessors without Customer Content access: Keycloak (auth), HubSpot (CRM), Google Analytics and Google/Bing/Meta Ads (marketing site only)
