What is not verified

No revenue figure was found. The pricing page lists plans, and the terms mention a paid subscription, but no source states that a customer has paid. A reader could look for a Stripe profile, a founder interview or a funding announcement. The number of people is not published, and no downloaded page names a founder. This story is grade E: the business is real and its product, price and customers are described from public pages, but no revenue figure was checked. Aiolum shows it as an idea worth studying, not as proof that it makes money.

Vanna AI sells an SQL agent: a program that takes a question in plain language and shows the answer from a database. It writes the SQL query, the language that databases answer to, and runs it. The framework is open source under the MIT license and works with several language models and databases. A hosted version adds admin features such as access control and audit logs.

The privacy page names Vanna AI, Inc. and says it is based in the United States, in Fairfield, Connecticut. The GitHub repository was created on 13 May 2023, and a web archive copy of vanna.ai from 18 May 2023 shows the same idea: "Vanna.AI lets you chat with your database". GitHub shows that the owner archived the repository on 29 March 2026, which makes it read-only.

No revenue figure was found, so the grade is E. The page lists self-serve plans at US$50 and US$500 a month, but no source states that a customer has paid. The number of founders and employees is not published either. The package file names Zain Hoda as the author.

01

Why did Vanna AI work?

Four causes, in the order they mattered. Each one is a reusable lesson.

01

Free code on GitHub drew more than 20,000 stars

The framework is open source under the MIT license, and the installation is one line, pip install vanna. The company's docs say the project passed 20,000 stars. The GitHub page confirms 23,804. The owner archived the repository on 29 March 2026.

02

Companies asked for permissions, and the hosted plans include them

The company's docs say its enterprise customers asked how to give each user different permissions. The home page offers access control, audit logs and data retention as optional hosted admin features. The pricing page says the plans include them.

03

The same code runs free or hosted, so users can upgrade

The pricing page says all tiers use the same core framework. A team can start self-hosted and later move to the managed cloud without rewriting code.

How it was built

These details come from the company's pages and from the Microsoft post. [1, 7, 9]

  • A Python package. The Microsoft post calls it an open-source Python RAG (retrieval-augmented generation) framework for SQL generation.
  • The home page lists language models from Anthropic, OpenAI, Gemini and Ollama. It also lists databases such as SQLite, PostgreSQL, MySQL, Snowflake and BigQuery.
  • The hosted version adds access control, observability, agent memory in a hosted vector database, file storage, audit logs and data retention.
  • The rewrite called Vanna 2.0 carries the user identity through every request, as the company's docs say.

Tools named in the sources

Each one opens its page in the Tools tab, with every story that uses it.

02

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

Two companies in our database of failed startups promised to turn company data into answers for non-specialists. The values below are from that database and are not independently verified. The match is loose. The cause line of DataNitro does not match its failure analysis, so both are given.

Died 2012 to 2015Burned US$120K

DataNitro

The promise

Let Python programmers run scripts inside Excel to automate data analysis.

Why it died

The failure analysis says the product was limited by Excel's architecture. It says later tools such as Jupyter notebooks and cloud analytics matured around it.

Ran out of cash
Died 2021 to 2024Burned US$5.0M

Lariat Data

The promise

Turn raw media data into insights for engineering, product and design teams.

Why it died

The failure analysis says strategic misalignment and competition as Tableau and Looker added AI to their products.

Competition

The failed startups come from our database of 1,749 dead startups, retold here in our own words. Its entries are AI-assisted summaries of public sources, so these cards carry no evidence grade.

What changed

Both predecessors sold data analysis to people who were not analysts, and both met stronger platforms. DataNitro depended on Excel. Lariat Data met larger analytics vendors that added AI.

Vanna AI differs in two ways. It gives the code away, so the first user pays nothing. It sells the parts a company needs to run it for many users, such as permissions and logs. Whether enough customers pay for that is not shown by any source found.

03

Can one person copy Vanna AI now?

Partly. The free-then-hosted structure can be copied; the traction cannot be checked.

Open-source code with a hosted paid tier is a repeatable structure. The proof of demand here is 23,800 GitHub stars, not paying customers. A reader can copy the structure but should look for payment evidence first.

Where it is still open: Other narrow jobs where a free framework brings developers and companies later pay for control: document extraction, test automation and search over private data.

  1. 1Publish the core as open source with a one-line install.
  2. 2Ask the first company users what blocks them from using it in production.
  3. 3Sell that part as a hosted plan, such as user permissions, audit logs and storage.
  4. 4Keep the open-source and hosted versions on the same code, so users can move up without a rewrite.

How much revenue does Vanna AI make?

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.

How to read this table. Grade C means the company states it on its own page. Grade B means a third party states it or it is visible in public code. No figure here is revenue.

When did Vanna AI launch, and how did it grow?

From a GitHub repository in May 2023 to an archived repository in March 2026. Each entry carries its grade.

  1. 13 May 2023BThe GitHub repository vanna-ai/vanna is created. On 18 May the Internet Archive saves vanna.ai with a free plan and a Premium Beta. [5, 6]
  2. 8 September 2023CThe company's blog announces that Vanna is available as an open-source package. Before that, the server was closed source. [12]

  6. November 2026BThe repository shows 23.8K stars and 2.5K forks. The site still lists the paid plans. [5, 2]

What could go wrong for Vanna AI?

The risks are the mirror image of the causes above.

What is not verified

No revenue figure was found. The pricing page lists plans, and the terms mention a paid subscription, but no source states that a customer has paid. A reader could look for a Stripe profile, a founder interview or a funding announcement. The number of people is not published, and no downloaded page names a founder.

Company claims without a source

The home page shows the badges "Open Source Production Ready" and "No Vendor Lock-in". The Premium page says the patterns are "refined across hundreds of production deployments" and the framework is "trusted by teams worldwide". No customer list backs these claims.

One quotation on the home page

The home page prints a quotation under the name Brian Spindolini, Senior Product Manager, Azure SQL Database. The same words are in the Microsoft post of 3 April 2024, whose author is shown as Brian Spendolini. The spellings differ.

The code repository is archived, and an earlier project exists

GitHub shows that the owner archived the repository on 29 March 2026, and no page gives the reason. The site, the price list and the sign-in page were online on 12 November 2026. The 2023 archive copy links to Pycob, an earlier project (github.com/pycob/pycob, created 15 January 2023). Both package files name the same author. No page says if Pycob was the same company.
