Overview

<p><b>Startup description</b></p><p>My platform helps TOEFL students improve their writing scores using AI-powered essay evaluation.</p><p>Students submit essays for TOEFL Writing tasks (Integrated + Academic Discussion) and receive instant scoring + feedback aligned with the official ETS rubric:</p><ul> <li>Task response</li> <li>Organization/coherence</li> <li>Grammar/language use</li> <li>Vocabulary/style</li> </ul> <p>Think of it as a 24/7 TOEFL writing grader that replaces expensive human feedback.</p><p>Built solo in 2025. Live for ~4 months. Currently runs almost fully on autopilot.</p><p><b>Current Metrics</b></p><ul> <li>Gross revenue: $500–600/month</li> <li>April gross revenue: $690</li> <li>~20 active paying users consistently</li> <li>Organic traffic + signups growing month-over-month</li> <li>Zero paid ads ever run</li> <li>No outbound marketing done</li> </ul> <p><b>Economics</b></p><ul> <li>AI costs: roughly $1–2/day total</li> <li>Estimated monthly infra + AI cost: ~$30–60/month</li> <li>Strong margins</li> <li>Maintenance time: &lt;2 hours/week</li> </ul> <p><b>Stack</b></p><ul> <li>Next.js</li> <li>Supabase</li> <li>Stripe</li> <li>Vercel</li> </ul> <p>I<b>mportant Note About MRR</b></p><p>Stripe MRR appears lower than gross revenue because TOEFL prep is highly seasonal and transactional.</p><p>Most users subscribe before their exam date, intensively use the platform, then cancel afterward. Some return during later prep cycles.</p><p>This is normal behavior for test-prep products.</p><p><b>Why I'm Selling</b></p><p>I need liquidity for an unrelated personal situation and need a relatively quick sale.</p><p>If not for that, I would continue operating the business. The product itself is healthy and still growing organically.</p><p><b>Growth Opportunities</b></p><p>Everything so far has come purely from organic traffic.</p><p>No serious distribution strategy has been executed yet.</p><p><b>Untapped Channels</b></p><ul> <li>Google Ads for high-intent TOEFL keywords</li> <li>TikTok/Reels/YouTube Shorts content</li> <li>SEO landing pages + blog posts</li> <li>Affiliate partnerships with TOEFL YouTubers</li> <li>Outreach to tutoring centers / prep schools</li> <li>Email funnels + score improvement campaigns</li> </ul> <p>A focused operator could realistically push this toward $1k–2k MRR within a few months.</p><p>The product works.

Expenses

~$60/month total. Breakdown: AI inference is the largest variable cost at roughly $30-45/month — currently less than $2/day for all 20 active users combined, often under $1/day. Vercel hosting ~$20/month. Supabase free tier (sufficient at current scale). Domain ~$1/month amortized. Stripe fees are netted out of gross revenue. No paid marketing, no employees, no contractors. Margins are approximately 85-90% gross.

Business Model

Subscription SaaS. Two plans: a monthly plan around $19/mo and a longer-term plan that drops the effective monthly price. Users pay via Stripe. TOEFL students typically subscribe for 1-2 months around their exam date, cancel, then reactivate for their next attempt. Gross revenue $500-600/month. Costs are tiny — about $30-60/month total in AI inference (~$1-2/day for all active users combined) plus standard Stripe/Vercel/Supabase fees. Clean margins, ~85%+ gross margin.

Target Audience

TOEFL test-takers preparing for the writing section — primarily international students applying to US/Canada/UK universities or graduate programs. Heavy concentration in India, China, Vietnam, Turkey, Brazil, and the Middle East. Most are aiming for a 26+ writing score and can't afford the $60+/essay that human graders charge. Secondary market: TOEFL prep tutors who want to scale feedback for their students.

Asking Price Reasoning

Asking $10,000 against ~$2,200 trailing revenue (4 months live). The price reflects three things: (1) the product is past PMF with organic monthly gross of $500-600 and growing, (2) margins are roughly 85-90% — costs run about $60/month total, mostly under $1-2/day in AI inference for all active users, and (3) growth levers are completely untapped.

Reason for Selling

I need urgent cash for an unrelated personal situation. That's the only reason. The product is healthy, organic signups are growing month over month, costs are tiny (~$1-2/day in AI inference for all 20 users combined), and I'd happily keep operating it if I didn't need the money now. This is a quick-sale, not a distressed asset — I'm pricing it below what a patient seller could get to close fast.

Growth Opportunity

(1) Google Ads on TOEFL writing keywords — clear buyer intent, low CPC in this niche. (2) One cornerstone SEO post ranking for "TOEFL writing 28+ score" could 5x organic traffic. (3) Affiliate partnerships with TOEFL YouTubers (100k-500k sub channels exist and none are monetized). (4) Founder-led short-form video — TOEFL rubric breakdowns and sample-essay scoring are perfect TikTok/YouTube Shorts content.

Competitors

Direct: WriteToScore, TestReady AI, GradeMyEssay, EssayGrader, TOEFL Resources premium tools. Indirect: ChatGPT/Claude (free but no TOEFL-specific rubric scoring), human TOEFL tutors on Preply/iTalki at $20-60/hour, and the official ETS TOEFL Practice Online ($45-90/test). Our edge: ETS-rubric-trained scoring + instant feedback + sub-$20 monthly price + zero setup. Most direct competitors are either too expensive, slower, or don't break down feedback by the four official scoring criteria.

Tech Stack

TypeScript, Stripe, TailwindCSS, Next.js, Supabase, Vercel.
