**The product.** Software that reads the 2D PDF sheets of a construction drawing set and lists errors, omissions and conflicts between disciplines. Experts at the company check each finding before the customer receives it. It is sold per sheet to contractors, developers and architects.

**Why it worked.** Founders who had managed hospital building projects built it for the people who pay for drawing errors. The company wrote that between the three founders they had managed more than US$3B in hospital projects, developed real estate and built enterprise software. The company names large contractors and developers as customers in its press releases.

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

Buildcheck sells software that reviews a drawing set, the group of plan sheets that a contractor builds from. The software uses computer vision, a kind of AI that reads images. It finds errors, omissions and conflicts between the architectural, structural, mechanical and electrical sheets. Its target is the change order, a paid change to the work after the contract is signed, which an error found late on site causes.

Three co-founders started it: Alexander Michalatos, Andrei Molchynsky and Alex Gureev. The company wrote that in 2023 it decided to build the tool, and a press release said it was founded at Stanford University. The company said in December 2025 that it raised US$5.9M in seed funding, and in September 2026 that it raised a US$12M Series A. Pulse 2.0 reported on 10 September 2026 that Telescope Partners led the round and that total funding is US$18M.

No revenue figure was found. The headline, more than 110 paying customers in September 2026, is the company's own statement, which Pulse 2.0 and AEC Magazine repeated. No source gives a price amount, revenue or headcount.

## Why did Buildcheck work?

### The founders had managed hospital building projects before

The About page says that between the three founders they had managed more than US$3B in hospital projects, developed real estate and built enterprise software. The page also says that the founders wanted the tool they wished they had had. Their earlier jobs are the company's own account.

### Experts check every AI finding before the customer sees it

The FAQ says that every review includes expert verification of the results, as part of the default service. AEC Magazine reported that in-house experts confirm that each issue is real and set its severity. This makes the product a mix of software and expert work.

### It reads the 2D PDFs that teams already have

The About page says that it works on the PDFs that teams already have, with no 3D models and no setup. The company says that 3D clash detection needs models that most projects do not have.

## How it was built

These details come from the company's own pages and press releases. They are grade C.

- The company says that it uses proprietary computer vision models that read components, geometry, dimensions and spatial relationships on 2D drawings.
- Its FAQ describes three groups of checks: drawing health, 2D clash detection, and omissions and logical rules. The number of checks differs between the company's pages.
- Experts at the company verify the AI output before it reaches the customer, as the FAQ and AEC Magazine say.
- The December 2025 post says that the models improve through work with the research institutes MILA and AMII.
- The company says that it turns a customer's own quality manuals into custom review agents, and that it compares revisions of a drawing set.

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

Three companies in our database of failed startups promised to change construction or to build software with human-assisted AI. 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.

### SmartSite (2016 to 2019; funding US$1.5M; cause: Competition)

- Promise: A platform for project management and resource allocation on construction sites.
- Why it died: It could not take enough market share fast enough to fend off competitors, as the record says.
- Record: 

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

- Promise: Faster and cheaper homes from factory-made wall panels.
- Why it died: The record says that the economics could not carry the capital cost of the model.
- Record: 

### Builder.ai (2016 to 2025; funding US$445M; cause: Unit economics)

- Promise: Custom software built by human-assisted AI.
- Why it died: The record says that each build needed much human work, so the costs stayed high.
- Record: 

## What changed

The three companies sold construction site software, factory-built homes and human-assisted AI. Their records name competition for one and unit economics for two. Buildcheck also pairs AI with human experts, which Builder.ai's record names as a cost problem.

The sources show two differences. Buildcheck sells to buyers that the press names, and it says that it charges per sheet. Whether the expert review keeps the cost low is not shown, because no source gives the company's costs or revenue.

## Can one person copy Buildcheck now?

**Verdict: Only with years of work in construction.**

The company's own account is that the founders knew the trade before they built the tool. A founder without that background has no source here for a way in. The structure is open: pick a task that buyers already do by hand.

1. Choose a task that experts in one industry do by hand, such as reading a drawing set sheet by sheet.
2. Make the tool work on the files the buyer already has, as the About page says Buildcheck does with PDFs.
3. Have experts check each result before the customer sees it, and say so, as the FAQ does.
4. Charge by the unit of work. The FAQ says that Buildcheck charges per sheet.

**What is still open.** Other review jobs that skilled people do by eye: permit packages, specifications and shop drawings.

## How much revenue does Buildcheck make? The numbers, graded

A company founded in 2023 that says it has more than 110 paying customers in September 2026, up from more than 50 in December 2025. All of it is the company's own statement

| Fact | Value | Grade | Note | Sources |
|---|---|---|---|---|
| Paying customers, September 2026 | more than 110 | C | Company post of 9 September 2026. Pulse 2.0 repeated it on 10 September and wrote that the company "has grown by more than 4x". Pulse 2.0 does not say what grew. Calculated here: 110 is 2.2 times 50. | [4, 5] |
| Paying customers, December 2025 | more than 50 | C | Company post of 9 December 2025. Pulse 2.0 repeated it on 14 December 2025. | [7, 8] |
| Customers named in the press, September and October 2026 | DPR Construction, EllisDon, Power Construction, IMC Construction, EMJ Construction | C | Pulse 2.0 and AEC Magazine name them. Both retell the company's release, so no independent source confirms that they pay. | [5, 6] |
| Series A, September 2026 | US$12M, led by Telescope Partners | C | Company post of 9 September 2026 for the amount. The company's post of 6 October, Pulse 2.0 and ENR name Telescope Partners as the lead. The banner on the company's site says "Telescope Ventures". | [4, 9, 5, 15, 1] |
| Seed round, December 2025 | US$5.9M, led by Uncork Capital | C | Company post of 9 December 2025 and Pulse 2.0 of 14 December 2025. | [7, 8] |
| Total funding | US$18M | C | Pulse 2.0 reported it on 10 September 2026, and the company's own post of 6 October 2026 states it. | [5, 9] |
| Company start | 2023, month not stated | C | About page: "In 2023, we saw an industry still reviewing drawings by eye" and "we founded Buildcheck". The legal name is Buildcheck AI, Inc. An Internet Archive copy of 3 April 2023 shows "BuildCheck AI, Inc." and a waitlist. In April 2024 the site offered checks of permit applications to cities and applicants. No earlier name was found. | [2, 12, 14] |
| Founders | Alexander Michalatos (CEO), Andrei Molchynsky (CBO), Alex Gureev (CTO) | C | The About page and the December 2025 post name them. The post says they founded the company at Stanford University. | [2, 7] |
| Team size | not published | C | No source gives a number. An archived About page of April 2024 names Deloitte, Stantec and Wix.com, which the founders' profiles today do not list. The December 2025 release says the funding will grow the engineering and operations teams. The September 2026 post says the company is looking for engineers, salespeople and researchers. On 31 August 2026 the company wrote that Plangrep was joining it. | [14, 7, 4, 11] |
| Pricing model | per sheet, volume discounts, unlimited seats, trial project | C | FAQ. No amount is published. | [3] |
| Drawings reviewed | more than 150,000 | C | Company post of 9 September 2026 says "drawings". Pulse 2.0 says "sheets". | [4, 5] |
| Time from the founding year to the Series A | up to 44 months | calc | Calculated: January 2023 to September 2026. The company gives no month. An archived copy of 3 April 2023 already shows the company name, so the true figure is 41 to 44 months. | [2, 4, 14] |

How to read this table. Grade C is a statement by the company, including when a journalist repeats it. A "calc" value was computed on this page. No value is grade A or B.

## Pricing

Buildcheck publishes no price amount. Its FAQ describes the pricing model, read on 11 November 2026 (grade C)

| Plan | Per month, billed yearly (US$) | Per month, billed monthly (US$) | Limit |
|---|---|---|---|


The FAQ says that Buildcheck charges per sheet with volume discounts. It says that every review includes unlimited seats in the platform fee and that a trial project comes first. The pages show no amount, and /pricing returned "404" on 11 November 2026. Internet Archive copies of the home page from April 2023, December 2023 and April 2024 show no amount either.

## When did Buildcheck launch, and how did it grow? Timeline

From a company founded in 2023 to a US$12M Series A in September 2026, as the company reported. Each entry carries its grade.

- **2023** (grade C [2]): The company wrote that it saw an industry still reviewing drawings by eye, and founded Buildcheck.
- **April 2024** (grade C [14]): An archived copy of the home page offered AI checks of permit applications to cities and applicants. No source dates the change to drawing review for contractors.
- **9 December 2025** (grade C [7, 8]): The company said it raised US$5.9M in seed funding and had more than 50 paying customers. Pulse 2.0 repeated this on 14 December.
- **31 August 2026** (grade C [11]): The company wrote that the team of Plangrep, which builds tools that read plans, was joining Buildcheck.
- **9 September 2026** (grade C [4, 5]): The company said it raised a US$12M Series A and had more than 110 paying customers. Pulse 2.0 repeated it on 10 September.
- **6 October 2026** (grade C [9, 6]): The company wrote that WND Ventures, the venture arm of DPR Construction, invested in the round after a pilot. AEC Magazine reported the Series A on 7 October and named five customers.

## What could go wrong for Buildcheck?

- **What is not verified.** No revenue figure was found. The company's pages and the press pieces give no revenue, no price amount and no headcount. The headline of more than 110 paying customers is the company's statement. A reader could look for a revenue figure in a later interview or a filing. Internet Archive copies show the same company name from 3 April 2023, so no earlier name was found. In April 2024 the site offered a different product: AI checks of permit applications for cities and applicants. No source dates the change to drawing review for contractors. The sources point to a team larger than the three founders, but none gives a number.
- **The paying customers are the company's own statement.** No independent source confirms that these customers pay. Pulse 2.0 and AEC Magazine name five customers, but both retell the company's release. The pages state a pricing model, per sheet, and show no price amount.
- **Counters, logos and quotations on the company's pages.** The home page shows about fifteen company names with credited quotations and two savings figures. Its heading says "Trusted by the world's leading owners, general contractors, and architects". One quotation is credited by first name and initial only, and some quotations name no company. Counters say "+150,000" drawings reviewed, "$3B+" in project value reviewed and "+50%" more meaningful comments. The pages say the company is SOC 2 Type II compliant and link to a trust page that was not read. The banner says "Join dozens of firms" while the About page says "More than 110". The number of checks is 300+ in the FAQ, over 400 in a post and 500+ on the About page. No source checks these. A search for two quotations found no copy on other pages.
- **Return on investment and expert review are the company's claims.** The company says its customers see 10 to 35 times return on investment, and the About page says over 20 times. No source gives the basis. Pulse 2.0 repeats the figures as the company's. The company also says that experts check every result, and nothing checks that either.
