How OpenAI went to market

PrimarySupportingTried, then dropped

1. 2020 to 2022

   API first, behind a waitlist

   OpenAI's first commercial product was a general-purpose API for developers, launched as a reviewed private beta in June 2020 and opened to self-serve signup without a waitlist in November 2021.

   • Developer-led

     The API launched in private beta with a mandatory production review before applications went live, and OpenAI said commercial products would help fund its research. In November 2021 developers in supported countries could sign up directly, and OpenAI said tens of thousands were already building on it.^[1],[2]

2. 2022 to 2023

   ChatGPT goes free, then paid, then to work

   ChatGPT launched free as a research preview in November 2022. A paid tier, cheaper API pricing, the Azure channel, and a sales-led Enterprise plan followed within a year.

   • Product-led

     ChatGPT was free during the research preview. In February 2023 ChatGPT Plus added a $20 per month tier with access at peak times while free access continued. Altman says the demo came from watching developers talk to the model in the API playground.^[3],[5],[30]

   • Usage pricing

     The ChatGPT model went on the API in March 2023 at $0.002 per 1,000 tokens, which OpenAI said was 10x cheaper than its existing GPT-3.5 models, and DevDay in November 2023 cut several prices again. Both were framed as passing savings to developers.^[6],[8]

   • Cloud marketplace

     From January 2023 OpenAI said it deployed its technology through its own API and Microsoft's Azure OpenAI Service, with Azure as the exclusive cloud for all its workloads. Microsoft's 10-K says it deploys OpenAI models across its own consumer and enterprise products.^[4],[27]

   • Sales-led

     ChatGPT Enterprise launched in August 2023 behind a Contact sales path. OpenAI said teams in over 80% of Fortune 500 companies had adopted ChatGPT, counted by accounts on corporate email domains.^[7]

   • Viral loop

     Shared links let a user send a whole conversation to anyone with the link, including through social networks. No source gives the feature's launch date or how many viewers become users.^[26]

   • Owned events

     DevDay, OpenAI's own developer event, was the venue for its November 2023 model, API, and price announcements.^[8]

3. 2024 to 2025

   Self-serve teams, ecosystem, and campus

   A self-serve Team plan sat below Enterprise, an app ecosystem formed inside ChatGPT, universities and teachers got their own versions, the paid ladder extended to $200, and OpenAI aired its first television ad.

   • Sales-assist

     ChatGPT Team launched in January 2024 at $25 per user per month billed annually, bought by upgrading in ChatGPT settings, and was renamed ChatGPT Business in August 2025. OpenAI says consumer familiarity makes business pilots shorter, and its then COO described a tail wind from organic consumer adoption.^{[9],[19],[31],[32]}

   • Land and expand

     By November 2025 OpenAI reported more than 7 million ChatGPT for Work seats, up 40% in two months, with Enterprise seats up 9x year over year. ChatGPT Edu was built from university Enterprise deployments.^[19],[12]

   • Partner channel

     The GPT Store opened in January 2024, with over 3 million custom GPTs created and a planned builder revenue program paid on engagement. By late 2025 Canva, Figma, Zillow, Spotify and others had apps inside ChatGPT, and retailers and payment firms were building on the Agentic Commerce Protocol.^[10],[19]

   • Education

     ChatGPT Edu for universities launched in May 2024. In November 2025 ChatGPT for Teachers was made free for verified U.S. K-12 educators through June 2028.^[12],[20]

   • Product-led

     The free tier received GPT-4o with usage limits in May 2024, and ChatGPT Pro added a $200 monthly plan in December 2024. Altman's 2025 letter to employees describes the aim as making it super easy for people to use for whatever they want.^{[11],[13],[15]}

   • Brand narrative

     OpenAI's first television ad aired during the February 2025 Super Bowl, framing AI as the Intelligence Age and aimed at people new to it. OpenAI had a Chief Marketing Officer by then.^[14]

4. 2025 to now

   Monetise every tier, sell through every cloud

   In October 2025 the for-profit became OpenAI Group PBC, a public benefit corporation in which the nonprofit OpenAI Foundation holds a 26% equity stake. OpenAI then widened the free base with a Go tier and ads, priced business use by usage, and from April 2026 sold through clouds other than Azure.

   • Cloud marketplace

     The October 2025 Microsoft agreement, signed alongside the recapitalization, kept Azure API exclusivity. The April 2026 amendment kept Microsoft as primary cloud partner with first-ship rights on Azure and let OpenAI serve all products on any cloud. OpenAI models, Codex, and managed agents launched on Amazon Bedrock the next day, with Codex usage counting toward AWS commitments.^{[17],[18],[23],[24]}

   • Product-led

     ChatGPT Go at $8 per month came to the U.S. in January 2026 after launching in 171 countries, and OpenAI said it would test ads in the free and Go tiers, with none in Plus, Pro, Business, or Enterprise. In March 2024 Altman had said he disliked ads as an aesthetic choice.^{[21],[22],[29]}

   • Usage pricing

     The CFO describes consumer subscriptions, workplace subscriptions with usage-based pricing, and a platform business where API spend grows with the outcomes delivered.^[22]

   • Sales-led

     The business announcement routes to Contact sales, and OpenAI counts more than 1 million organizations paying through ChatGPT for Work or the developer platform.^[19]

“Reported” figures come from trade press, not the company, and are shown with their date.

• “OpenAI is a consumer company.”

  Partly true

  ChatGPT's consumer base is OpenAI's largest user population, and about 70% of consumer usage is non-work. But OpenAI's first commercial product in 2020 was a developer API, it has sold a sales-led Enterprise plan since 2023, it reports more than 1 million paying business customers, and its CFO lists consumer subscriptions as one revenue line alongside workplace subscriptions, usage pricing, and APIs. OpenAI describes consumer use as feeding business adoption.^{[16],[1],[7],[19],[22]}

• “ChatGPT grew with no marketing.”

  Partly true

  ChatGPT launched as a free research preview, Altman says the scale of the response surprised the company, and the then COO attributes consumer growth to word of mouth. But by February 2025 OpenAI had a Chief Marketing Officer and ran its first television ad during the Super Bowl, aimed at people who had not tried it. No source gives a marketing spend figure for any period.^{[3],[30],[31],[14]}

• “We had been watching people use the playground feature of our API and knew that developers were really enjoying talking to the model.”

  Sam Altman, CEO, OpenAI^[30]

  Reflections, paragraph 5

• “Our enterprise momentum is fueled in part by consumer adoption.”

  OpenAI, 1 million business customers, November 2025^[19]

  Section "From personal use to companywide impact"

• “our business model should scale with the value intelligence delivers.”

  Sarah Friar, CFO, OpenAI^[22]

  Paragraph 8

• A free consumer product can be the top of an enterprise funnel, if you count the corporate domains inside it.

  Works when: The same product is useful at home and at work, individuals can sign up without IT, and the paid business tier adds what employers need, such as data controls, SSO, and admin, rather than different features.

  Backfires when: The consumer use case has nothing to do with the work use case, or employers ban personal accounts, so the consumer base never carries into a company deal.

  Based on: ChatGPT goes free, then paid, then to work, Sales-led; Self-serve teams, ecosystem, and campus, Sales-assist

• Ship the developer platform first, then let a consumer product show which use people keep coming back to.

  Works when: The core capability is general-purpose and the best application is unknown, so developer usage is a cheap way to watch which interaction holds attention.

  Backfires when: The product is narrow and the use case is already known, so an API-first period delays the end-user product without teaching anything.

  Based on: API first, behind a waitlist, Developer-led; ChatGPT goes free, then paid, then to work, Product-led

• Add tiers in both directions from a free base: a cheaper tier below and a premium tier above.

  Works when: Unit costs are real and vary by user, willingness to pay varies by orders of magnitude, and the free base is large enough that a small paid share is material.

  Backfires when: The free tier is cheap to serve and the user base is small, so extra tiers add decision friction and support load without meaningful revenue.

  Based on: ChatGPT goes free, then paid, then to work, Product-led; Self-serve teams, ecosystem, and campus, Product-led; Monetise every tier, sell through every cloud, Product-led

• A cloud exclusivity can bring distribution early and limit it later, so agree the exit terms up front.

  Works when: A hyperscaler partner brings capital, compute, and enterprise procurement paths you cannot build alone.

  Backfires when: Your buyers standardise on another cloud and the exclusivity keeps you out of their marketplace and committed-spend budgets.

  Based on: ChatGPT goes free, then paid, then to work, Cloud marketplace; Monetise every tier, sell through every cloud, Cloud marketplace
