**The product.** An AI agent that reads a whole construction drawing set together with its specifications and the building codes, and returns a list of issues, each cited to the sheet and the code section. A check is bought online and priced per drawing page, the first 10 pages are free, and an API and an MCP server let other software send drawing sets. An older iPhone and web app turns site photos and voice notes into field reports.

**Why it worked.** Mistakes in drawings, such as a door below the minimum width in the code or a duct that runs through a beam, are often found only on site, where fixing them means rework and delay. People do not check hundreds or thousands of pages against each other well. The founder knew the trade: by his own account he ran an engineering firm before and his father is a structural engineer. The company made the check something a firm can buy without a sales call.

Evidence grades: A = disclosed by a public company, a filing or a payment processor, or verified by one; B = two or more independent reports agree, or a journalist confirmed it; C = a founder claim that no one else verified; D = reported, not verified: one founder claim or a third-party estimate with no second source; E = no revenue figure found, so the headline is a non-money fact and the other facts carry their own grades; calc = computed on this page from graded facts.

## Summary

InspectMind AI sells an AI plan check, a review of construction drawings by AI models before the city's plan checker or the builder sees them. A customer uploads the drawing set, the full stack of architectural, structural, civil and MEP drawings (mechanical, electrical and plumbing) with the written specifications, as PDF files. The AI agent returns a list of issues such as code violations, dimensions that disagree between sheets and materials that do not match the specification, each cited to the sheet and the code section.

Aakash Prasad (CEO) and a co-founder and CTO, Shuangling, launched it on 16 January 2024 during Y Combinator's Winter 2024 batch, first as an app that turns an inspector's voice notes and photos into an inspection report. In that launch post Prasad wrote that he had founded an architecture and engineering firm as a teenager and grown it to a US$15 million annual run rate; this page did not check that claim. In November 2025 the company relaunched the product as a checker agent for drawings, and in November 2026 the Y Combinator page lists 6 people.

No revenue figure was found, so this is a grade E story and its headline is the product's status. The home page says more than 600 firms use it, and the company said in November 2025 that its agent saved one general contractor US$2 million of rework. Both are the company's own claims, and a customer's saving is not the company's revenue.

## Pricing

InspectMind prices on 7 November 2026, from the company's pricing page (grade C). A check is priced per page, not per month

| Plan | Per month, billed yearly (US$) | Per month, billed monthly (US$) | Limit |
|---|---|---|---|
| Free | 0 | 0 | one check on up to 10 drawing pages, no card |
| Standard | 2.50 per drawing page |  | US$1.50 per page after 100; US$0.25 per spec page; 1 building code; US$25 minimum per check |
| Pro | 4 per drawing page |  | US$0.50 per spec page; up to 3 codes and a design review; US$100 minimum per check |
| Max | 6 per drawing page |  | US$0.75 per spec page; every code and a design review; US$200 minimum per check |
| Teams and enterprise | custom |  | volume rates, monthly invoicing, single sign-on |

The pricing page charges per drawing page, with a lower rate for specification, report and reference pages; code pages are not charged. The checker shows the exact price before payment, and checkout runs through Stripe. Every paid plan uses the same AI models and differs only in scope: Pro and Max add an engineering design review. The pricing page promises a full refund if a check finds fewer than 5 meaningful issues. Teams can ask for volume rates and monthly invoicing. The March 2025 launch post said plans then started at US$100 a month; existing prepaid and contract customers keep their old pricing, the page says.

How to read this table: a grade C value is the company's or the founder's own statement on its site or in its Y Combinator launch posts. A grade B value comes from Y Combinator's or Apple's own listing. A "calc" value (grade X) was computed on this page. No value is grade A, and no revenue figure was found.

## When did InspectMind AI launch, and how did it grow? Timeline

From a voice-to-report app for inspectors to a drawing checker sold per page, in 34 months. Each entry carries its grade.

- **2023** (grade B [3]): InspectMind AI is founded in San Francisco and joins Y Combinator's Winter 2024 batch.
- **16 January 2024** (grade C [4]): First launch post: an iOS and web app that turns voice notes and photos from site visits into inspection reports, by Aakash Prasad and Shuangling.
- **13 March 2025** (grade C [5]): Second launch post: a growing library of report templates for construction, engineering, insurance and real estate, Word reports, and plans from US$100 a month.
- **27 November 2025** (grade C [6]): Third launch post: an AI checker agent that scans drawings, specifications and building codes for issues. The company says it saved a general contractor US$2 million of rework.
- **7 November 2026** (grade C [1, 2, 3, 8]): The site sells checks per drawing page in four plans, offers an API and an MCP server, and says more than 600 firms use it. Y Combinator lists 6 people.

## Why did InspectMind AI work?

### From reports to drawing review

The first product wrote inspection reports from what an inspector saw on site. The November 2025 relaunch moved earlier in the project, to the drawings, where an error can be fixed on paper instead of on site. The home page in November 2026 is only about drawing review; field reports are a separate product.

### Priced per page, with a refund promise

A check costs a rate per drawing page with a minimum, the price is shown before payment, and the first 10 pages are free. The pricing page, read on 7 November 2026, lists US$2.50 per drawing page on the Standard plan and promises a full refund when a check finds fewer than 5 meaningful issues. A firm can try it without a contract or a sales call.

### Several model providers behind one product

The company writes that each check runs across frontier models from OpenAI, Anthropic and Google together with its own document-processing models, and that the mix changes as new models ship. Its own work is the part around the models: reading a set of thousands of pages, comparing sheets with each other, and citing the code section that a city adopted.

### Fits the tools firms already use

Findings go into Autodesk Construction Cloud or out as Bluebeam markups, and an API and an MCP server let other software and AI assistants send drawing sets. A customer can also upload its own prototypes and checklists, so every later set is checked against them.

## How it was built

These details come from the company's own pages (home page, llms.txt and humans.txt) and are grade C.

- Web front end in React and TypeScript, built with Vite, Tailwind CSS and shadcn/ui; the site lists Cursor, VS Code and Figma as its software.
- Site hosted on Heroku; customer documents stored and processed on AWS in the United States.
- Checks run on frontier models from OpenAI, Anthropic and Google plus the company's own document-processing models.
- Payments through Stripe checkout; PostHog and Google Analytics for analytics.
- SOC 2 Type II audit in progress with Vanta, and single sign-on with SAML, for large customers.

## Who tried this before InspectMind AI, and why did they fail?

Three companies in our database of failed startups promised to remove the waste in construction with technology and failed. The values below are from that database and are not independently verified.

The failed startups come from our database of dead startups, retold here in our own words; Its entries are AI-assisted summaries of public sources, so they carry no evidence grade.

### Katerra (2015 to 2022; funding US$2.6B; cause: Unit Economics)

- Promise: Vertically integrate construction from design to supply chain to building, to remove the industry's inefficiencies.
- Why it died: Built factories and supply chains before it had the demand for them, then bought other companies on its way to bankruptcy.
- Record: 

### Veev (2008 to 2024; funding US$647M; cause: Unit Economics)

- Promise: Factory-built wall panels with wiring, plumbing and HVAC inside, so homes are assembled in days.
- Why it died: Priced homes above what the mass market pays, and its factory kept spending money when high interest rates cut housing demand.
- Record: 

### Social Construct (2017 to 2020; funding US$17M; cause: Ran Out of Cash)

- Promise: Build housing faster and cheaper with technology and streamlined processes.
- Why it died: Underestimated the regulation and the complexity of construction, and ran out of money in the pandemic.
- Record: 

## What changed

The three predecessors tried to fix construction by building: factories, panels, their own projects. That needed hundreds of millions of dollars and tied them to housing demand and interest rates. InspectMind does not build anything; it checks the drawings that builders already make and sells each check on its own.

The company writes that it uses "leading models from OpenAI, Anthropic and Google" and that the difference is what it built around them: reading whole sets of thousands of pages, comparing sheets with each other and citing the code section. So it rents the reading ability per use and spends its own work on construction knowledge, which keeps its costs tied to the number of pages checked instead of to factories.

## Can one person copy InspectMind AI now?

**Verdict: The pricing model, yes. The trade knowledge, only with years in the field.**

A per-page AI check with a free first run and a refund promise can be built by a small team on rented models. What is hard to copy is knowing which errors matter on a building and which code section applies in which city; the founder brought that from an engineering firm and a structural engineer father, by his own account.

1. Pick a document that a regulated trade must check page by page, such as drawings, submittals or inspection reports.
2. Cite the page and the rule for every finding, so a licensed professional can verify it in seconds.
3. Sell each check online at a price per page shown before payment, with a free first check.
4. Connect to the tools the trade already uses, such as Autodesk Construction Cloud or Bluebeam, instead of asking it to change how it works.

**What is still open.** Other page-by-page reviews in regulated trades: shop drawings and submittals, fire and life-safety plans, accessibility reviews, and local code amendments outside the United States.

## What could go wrong for InspectMind AI?

- **What is not verified.** No revenue figure was found. This page looked for a TrustMRR profile (there is none in its list), a founder interview with figures, and a filing, and found none. The home page claim of more than 600 firms and the November 2025 claim that a general contractor avoided US$2 million of rework are the company's own statements, with no second source; that saving belongs to the customer and is not revenue. A reader could look for figures from Y Combinator's Demo Day or a press interview with the founder.
- **Testimonials and the firm count.** Most customer quotes on the home page give a full name and a company, and one links to a case study. Two are signed with a first name and a company only, and two with a role only ("Retail store development team" and "VP of Construction, national production builder"). The "600+ firms" figure is not backed by a list on the pages read.
- **Competition and model providers.** On this site the closest stories are InspectProHQ, home-inspection report software, and Blueprint Crusher, cost estimating from tender documents; InspectMind checks the drawings themselves. The company writes that each check runs on models from OpenAI, Anthropic and Google, so changes in their prices or terms would reach its costs, although no single provider is required.
- **Changes in the product and the team.** The product changed from field reports (2024) to drawing review (late 2025), and the iPhone app is now the separate field-report product, still updated in October 2026. The co-founder and CTO named in the 2024 and 2025 launch posts is not listed as a founder on the Y Combinator page read in November 2026; no source explains this.
- **A page on the founder's faith.** The site menu links to a page in which the founder describes his Christian faith and says he has pledged the proceeds of all his founder shares to charity through Founders Pledge. The same page says that religious belief is never a condition of employment or of doing business with InspectMind.
