● ClaimedSingle month

TL;DR

  • Figure: $210K+ in one month (Single month · Dec 2025 · founder X post)

    ≈ $210,000/month in USD — one month of revenue, not recurring.

  • Proof level: Claimed. All figures are founder posts on X (re-retrieved on 15 Oct 2026). Consistent over time, but no payment-provider verification is available.
  • Our verdict (4/10, opinion): Consistent founder reports and very low running costs (users pay their own API usage). But a UI layer has a thin moat as LLM vendors' own apps improve, and his distribution did much of the work.

The story

Tony Dinh is an indie maker with earlier products (DevUtils, BlackMagic, Xnapper). He launched TypingMind in 2023 as a better ChatGPT UI and hired one developer and one designer in April 2025.

  1. Mar 2025 (posted 5 Apr 2025) — $148k revenue in the month — founder post on X
  2. Apr 2025 (posted 2 May 2025) — $170,005 revenue in the month — founder post on X
  3. Dec 2025 (posted 1 Jan 2026) — $210K+ in the month (all-time high); 8,000+ new customers in 2025 — founder post on X

Monthly revenue mixes one-time licenses and team plans, so it is not MRR.

Business model

  • What it sells: a chat UI for LLMs (bring your own API key) plus a Team version.
  • To whom: power users and teams.
  • Pricing: one-time license raised over time $9 → $19 → $29 → $79, plus a recurring Team plan (founder thread, Jun 2024). Current prices: Research in progress.
  • Acquisition: founder build-in-public audience on X; other channels: Research in progress.

Agent blueprint

Our suggestion — not how the founder did it

  1. Step 1

    Builder agent

    Ships UI features and new model integrations

  2. Step 2

    Support agent

    Answers license and setup questions

  3. Step 3

    Growth agent

    Drafts build-in-public posts and changelogs

Human in charge

A person approves money, public posts and key decisions. We don't estimate how much human work this saves.

Agentic-ness today (our estimate): 3/5 · Difficulty: Medium

Our take (opinion)

  1. Find friction in a popular AI tool's UI.
  2. Build a polished alternative that uses customers' own API keys.
  3. Sell a one-time license, raising price as features grow.
  4. Add a Team plan for recurring revenue.
  5. Build in public.
  • Skills: Front-end engineering, product polish
  • Audience needed: Yes — a big factor

Risks & limits

  • Thin moat: LLM vendors' apps keep catching up.
  • Depends on founder distribution.
  • Self-reported figures only.

Our verdict

Editorial opinion

4/10

Replicability today: 4/10. Consistent founder reports and very low running costs (users pay their own API usage). But a UI layer has a thin moat as LLM vendors' own apps improve, and his distribution did much of the work. (Editorial opinion.)
