EssayGrader grades student essays with a large language model. A teacher gives it a rubric, the table of criteria and score levels that a teacher uses to grade an assignment, and a stack of essays. It returns a suggested score for each criterion and written feedback for each student. It connects to the LMS (learning management system, the school software where students hand in work, such as Google Classroom or Canvas), so the teacher does not have to download and upload files. Paid plans cost US$14.99 to US$49.99 a month for one teacher, and schools buy licenses by quote.
Two owners ran it, and this page keeps their numbers apart. A software engineer built it: the company's About page credits a developer named Payton with the idea, after he saw how much grading his wife, an English teacher, took home, and with the first version. It launched on Product Hunt on 8 February 2023. In February 2024 he sold it through the Acquire.com marketplace. The buyer, Chan Yerneni, said on the Buying Online Businesses podcast that he paid US$125,000 in cash at a revenue multiple of about 2, which means the price was about two times one year of revenue. Acquire.com and the buyer put the revenue at the sale at about US$5,000 of MRR, monthly recurring revenue from subscriptions. The headline of this page is that sale, the outcome for the one-person business that the engineer built.
Everything after the sale belongs to the buyer and the team he hired. He switched on live chat support, says he spoke to 300 to 400 teachers in the first year, and built what they asked for: AI-writing detection, plagiarism checks, analytics and LMS integrations. In July 2025 Acquire.com wrote that he and a six-person team were closing school and district contracts and that the business was on track to pass US$1 million of ARR (annual recurring revenue, the MRR times 12). In November 2025 the podcast's notes said that he had grown it to US$80,000 a month. The price is the buyer's own statement in an interview, grade B. All revenue figures come from the buyer alone, grade C, and some of them disagree with each other.
How much did EssayGrader make, and what was it sold for?
Each row shows the evidence grade and the source numbers from the list at the end of this page. The grades are explained in How Aiolum verifies.
| Fact | Value | Grade | How we know | Sources |
|---|---|---|---|---|
| Sale price, February 2024 | US$125,000, all cash | B | The buyer's statement on the Buying Online Businesses podcast. The show notes say he bought it "for $125K in cash at a 2x revenue multiple" (they misspell the name as SAGrader.ai). ProvenStartups' summary of the video adds February 2024 and that he paid slightly more than the seller asked. No seller statement and no Acquire.com record of the price were found. | [1, 6] |
| Revenue at the sale | about US$5,000 a month (MRR) | C | Acquire.com's blog and its podcast page, July 2025, both from the buyer's interview. Acquire.com's other site, Bootstrappers.com, wrote in March 2025 that it made US$8,000 a month. | [2, 4, 3] |
| Price compared with revenue | about 2.1 times one year of revenue | calc | Calculated: US$5,000 times 12 is US$60,000 a year, and US$125,000 divided by US$60,000 is 2.08. This agrees with the stated 2x multiple. With US$8,000 a month the multiple would be 1.3, so the US$5,000 figure fits the stated deal better. | [1, 2] |
| Users at the sale | about 400, mostly individual teachers | C | Bootstrappers.com, March 2025, from the buyer. | [3] |
| Time from launch to sale | 12 months | calc | Calculated: Product Hunt launch on 8 February 2023 to the sale in February 2024. | [12, 6] |
| Revenue, March 2025 | "over five times" the US$8,000 a month at the sale, so more than US$40,000 a month | C | Bootstrappers.com, 21 March 2025, from the buyer. The US$40,000 is calculated on this page: 5 times US$8,000. | [3] |
| Revenue, July 2025 | "on track to cross $1M in ARR" | C | Acquire.com blog and the Startup Acquisition Stories podcast page, 21 July 2025. The podcast title says the buyer 10x'd the revenue; 10 times US$5,000 is US$50,000 a month (calculated). Starter Story quotes an X post from the same week: "Quit a corporate job and acquire'd a $5K MRR SaaS. Now on track for $1M ARR." | [2, 4, 13] |
| Revenue, November 2025 | about US$80,000 a month, "hitting $1M in annual recurring revenue" | C | Buying Online Businesses podcast notes and YouTube description, 5 November 2025, from the buyer. They say he reached it "less than a year" after buying; the July 2025 report above still said "on track", so the month it was reached is unclear. ProvenStartups notes that the host first said US$800,000 and corrected himself on air. | [1, 5, 6] |
| Run rate from the November 2025 figure | about US$960,000 a year | calc | Calculated: US$80,000 times 12. Growth from US$5,000 to US$80,000 a month is 16 times, over about 21 months from February 2024 to November 2025. | [1] |
| Team after the sale | the buyer alone at first; "his CTO and a small team of developers" by March 2025; a "six-person team" by July 2025 | C | ProvenStartups, Bootstrappers.com and Acquire.com, all from the buyer. The About page lists Suraj Reddy as co-founder and CTO and the original builder and his wife as advisers. | [6, 3, 2, 7] |
| Outside funding | none | C | The buyer told Bootstrappers.com: "We had private equity firms and VCs reach out last year. But we turned them down." ProvenStartups says he paid from just under US$200,000 of savings. | [3, 6] |
| Buyer's own income in 2024 | less than he earned at a student job | C | The buyer: "I had made more money as a student working at Subway than I made in 2024 at EssayGrader." Revenue went back into the product. | [3] |
| Teachers using it | 100,000+ in March and November 2025; 200,000 claimed in October 2026 | C | Company and podcast claims, not counts of paying users. The pricing page says that by July 2026 more than 200,000 educators had graded more than 3.5 million assignments. | [3, 1, 8, 9] |
| Search position | "ranks #1 for its top keywords" and has "over 60% of search traffic for 'AI essay grading'" | C | Acquire.com blog, July 2025, from the buyer. The directory indexator.ai estimated 107,000 visits in May 2026, 62.1% of them from organic search, and 17,350 searches a month for "essay grader". | [2, 14] |
| Grading accuracy claimed by the company | 94% of criterion scores within one point of a human score, 22,000+ essays, July 2026 | C | The company's own study on its pricing page. No outside audit is cited. | [9] |
How to read this table: grade B is the buyer's own statement of the price he paid, given in a podcast interview. Grade C values are statements by the buyer in interviews and on Acquire.com's sites, or claims on the company's own website. Grade D is a third-party estimate or an AI-compiled profile. A "calc" value (grade X) was computed on this page from the rows above it. No payment processor has confirmed any figure.
| Plan | Per month, billed yearly (US$) | Per month, billed monthly (US$) | Limit |
|---|---|---|---|
| Basic | 0 | 0 | 100 essays a month, 1,000 words each |
| Pro | 14.99 | 19.99 | 350 essays a month, 3,500 words each, AI-writing and plagiarism detection |
| Premium | 34.99 | 49.99 | 800 essays a month, 8,000 words each, automatic detection |
| School District / Higher-Ed | custom | 25+ users, quote |
The page shows US$14.99 and US$34.99 per month with a Monthly / Annually switch labelled "UP TO 30% OFF"; the page's script swaps in US$19.99 and US$49.99. Because US$34.99 is exactly 30% below US$49.99, this page reads the lower pair as the price per month billed yearly and the higher pair as the monthly price. That reading is an inference. The free Basic plan grades 100 essays a month. Schools and districts with 25 or more users get a quote. The directory indexator.ai also lists a Lite plan at US$6.99 a month, which the current page does not show.
When did EssayGrader launch, and how did it grow?
From a side project for one teacher's grading load to a school-district product, with the sale in the middle. Rows before February 2024 belong to the builder; rows after it belong to the buyer.
- 8 February 2023CThe builder launches EssayGrader on Product Hunt: software that "reduces the time it takes teachers to grade essays/papers using AI", with feedback reports, error reports and summaries; "AI detection tool coming soon!" It finishes 32nd of the day with 71 points. [12]
- End of 2023CChan Yerneni, a senior product marketing manager at OpenText with a baby on the way, decides to buy a business instead of starting one. He reviews listings on Acquire.com every morning for about 90 days and looks at 25 to 30 businesses. [2, 1, 6]
- February 2024BHe buys EssayGrader for US$125,000 in cash at about US$5,000 a month, by his account. The seller is described as a technical founder who did not want to grow it. Funds go through Escrow.com; discovery to full transfer takes about a month. [1, 2, 6]
- May or June 2024CHe switches on live chat support and answers teachers himself. He says he spoke to 300 to 400 teachers in the first year (in another interview, "over a thousand"). [6, 2, 3]
- 2024CHe hires customer-facing developers, redesigns the interface, improves the grading engine, learns SEO and hires an SEO partner. Teachers ask for AI detection, plagiarism checks, analytics and Google Classroom and Canvas integrations. [2, 3]
- 21 March 2025CBootstrappers.com reports revenue "over five times" the US$8,000 a month it gives for the sale, 100,000 educators, and that he turned down investors. [3]
- 21 July 2025CAcquire.com's blog and podcast: on track to pass US$1 million ARR, a six-person team closing school and district contracts, adoption in over 35 U.S. states, and a goal of US$2 million ARR within two years. [2, 4]
- 5 November 2025COn the Buying Online Businesses podcast the buyer's revenue is given as US$80,000 a month, about US$1 million ARR. [1, 5]
- July 2026CThe company says 200,000 educators have graded more than 3.5 million assignments and that it has data privacy agreements with over 100 schools in more than 30 U.S. states. [9, 8]

Why did EssayGrader work?
Four causes, in the order they mattered. Each one is a reusable lesson.
A narrow, painful job
Grading essays is the part of teaching that teachers take home. The builder made the product after seeing his wife's grading load, and the buyer, a former teacher, says he chose it over listings with better revenue because "I was a former teacher. I knew the pain point." A tool for one repeated task can be sold to one teacher at a time with a card, without waiting for a school budget.
Buy traction instead of building it
The buyer's test for a listing, as ProvenStartups quotes it: "What would happen if this business is turned off tomorrow? Are there at least 100 people that are going to lose their minds?" He told Acquire.com not to fixate on profitability when a business is below about US$200,000 and to look for early product-market fit, meaning proof that some customers want the product badly. He said he paid about two times a year of revenue, so the risky first year was already behind the product.
Talk to every customer, then build what they ask
The buyer turned on chat support and answered it himself. The features that drove growth, by his account, were teachers' requests: AI-writing detection for the teacher, plagiarism checks, writing analytics and direct LMS integrations. He said: "The features that made the biggest difference weren't things I thought of."
Teachers sell it to their schools
Teachers who used it told colleagues, and some asked their districts to pay. That turned individual subscriptions into school and district licenses, which need security reviews, data privacy agreements and training sessions, and that is where the team of six came in. Search did the rest: the buyer says the site ranks first for its main keywords, and a traffic directory puts organic search at 62% of visits.
How it was built
These details come from the company's Terms of Service and pages and from the buyer's interviews. They are grade C. Nothing public describes the builder's original code. [11, 4, 8, 9, 2]
- The Terms of Service list the third-party services the product uses: OpenAI, PromptLayer (a tool for logging and managing prompts sent to language models), Pinecone (a vector database, which stores text as numbers so similar text can be found), Dropbox, Google Classroom and Canvas LMS.
- The same Terms name the vendors that run it: Stripe for payments, and DigitalOcean and Heroku for hosting.
- The buyer "rebuilt the product from scratch" after the purchase, according to Acquire.com's podcast page, with a CTO and customer-facing developers.
- Integrations with Google Classroom, Canvas and Schoology are built into the product, so teachers import submissions and send grades back without extra software.
- For schools it signs data privacy agreements and says it complies with the U.S. student-privacy laws FERPA and COPPA and with California's CCPA, and that student work is not used to train AI models.
- Before buying, the buyer checked each listing's search traffic with Ahrefs and SEMrush and signed NDAs to see financials; the payment went through Escrow.com.

Who tried this before EssayGrader, and why did they fail?
Four companies in the Loot Drop database tried to sell teachers software for grading, assessment or classroom records, all between 2010 and 2013. The values below are from that database and are not independently verified.
ClassroomIQ
The promiseGrade paper exams and assignments faster through a digital interface.
Why it diedSchools adopted technology slowly and the product did not make grading itself automatic.
Edusight
The promiseA platform for K-12 teachers to track student performance and manage assessments.
Why it diedSchool bureaucracy slowed sales and better-funded rivals such as ClassDojo and Seesaw won the classrooms.
BrightLoop
The promiseLet teachers record and share student progress in real time.
Why it diedTeachers were slow to adopt new tools, and Google's free tools did the job before the company could raise money.
Blendspace
The promiseHelp teachers build digital lessons from content on the web.
Why it diedGoogle Classroom covered the need for free, and a freemium model brought users but little revenue.
The failed startups come from Loot Drop, a free database of dead startups, retold here in our own words. Loot Drop describes its entries as AI-assisted summaries of public sources, so these cards carry no evidence grade.
What changed
All four sold teachers a better way to organize work that the teacher still had to do. They needed school budgets, and Google gave schools free tools that did much of the same. They raised money, so they needed fast growth that schools could not give them.
EssayGrader differs in three ways. The language model does the slow part, reading and commenting on each essay, so the time saved is hours a week rather than minutes, and the company claims 6 to 10 hours a week from a survey of its own users. It connects to Google Classroom and Canvas instead of competing with them. And it is sold first to single teachers for US$14.99 to US$49.99 a month, so revenue arrived before any district purchase; the buyer said the district contracts came later, when teachers asked their schools to pay. Under the builder this was enough for a sale at US$125,000 after one year, by the buyer's account.
Can one person copy EssayGrader now?
The build was copyable in 2023. The purchase is copyable now.
An engineer with a teacher at home built a small AI grading tool and sold it after a year. The buyer's method is the more repeatable part: buy a small product with paying users in a market you know, then talk to the users and build what they ask for. It needs capital (he said US$125,000 in cash) and a buyer who can sell to schools.
Where it is still open: Grading and feedback for other written or spoken work: lab reports, language-learning speaking tests, nursing care plans and job-training assessments, and small listed products in these niches whose builders do not want to grow them.
- 1Build for one repeated, hated task of one profession that you can watch at close range.
- 2Charge single users by card from the start, so you do not wait for an institution's budget.
- 3If you buy instead of build, review dozens of listings, check traffic and financials, and choose a market you understand over the highest profit.
- 4Answer support chat yourself in the first months and turn the most common requests into features.
- 5Add the paperwork that institutions need (privacy agreements, security reviews, training) once users start asking their employers to pay.
What could go wrong for EssayGrader?
The risks are the mirror image of the causes above.
Every money figure comes from the buyer
The price, the revenue at the sale and every later revenue figure are the buyer's statements in interviews, most of them on Acquire.com's own blog, podcast and Bootstrappers site, which promote buying through Acquire.com. No payment processor profile, seller statement or filing confirms them.
The accounts disagree in places
Revenue at the sale is US$5,000 a month in three sources and US$8,000 in one. The deal took "three days", "within days", "about three weeks" or "about a month". He spoke to "300 to 400" or "over a thousand" teachers. The November 2025 notes say US$80,000 a month was reached in less than a year, but in July 2025 the business was still "on track" for US$1 million ARR. The pricing page says the product launched in September 2023, while Product Hunt shows a launch on 8 February 2023.
Founder or buyer
The About page calls the buyer "Founder & CEO" and says the company began with a team of four, including him. His own interviews say he bought a product that someone else built. This page treats the engineer as the builder and the buyer as the owner who grew it.
Not a one-person business after the sale
The headline is the sale of a side project built by one engineer. The later growth to about US$80,000 a month, by the buyer's account, came with a CTO, developers and a six-person team by July 2025.
AI grading depends on trust and on suppliers
Teachers and districts must trust the scores; the company's accuracy study is its own. The product runs on OpenAI's models and on access to Google Classroom, Canvas and Schoology, which those companies control, and competitors such as CoGrader sell the same idea.
