Jared Palmer argues that the most successful open-source strategy involves a free, complementary project (like Next.js) that drives adoption for a separate, closed-source paid product (like Vercel). Simply trying to convert free users of a core open-source product is a common pitfall.

For five years, Mailtrap was a free tool that grew slowly and organically through word-of-mouth in the developer community. This patient, community-led approach established deep-rooted trust and brand loyalty before monetization was ever considered. This foundation became a durable competitive advantage that well-funded competitors could not easily replicate.
According to Databricks CEO Ali Ghodsi, monetizing open source requires two consecutive successes. First, the open source project must achieve global adoption. Second, you must build a proprietary, 10x better product on top of it to create a defensible business.
Many founders mistakenly view freemium as a complete business model. It's actually a top-of-funnel acquisition strategy that replaces marketing spend with a free product to generate leads. The real business model is the subsequent upsell to paid tiers.
Entrepreneurs rush to market with an MVP, often giving away the 20% of features that drive 80% of customer willingness to pay. They then spend time building the less valuable 80%, inadvertently training customers to expect more for less and making future monetization difficult.
Vercel's CTO Malte Ubl outlines a third way for open source monetization beyond support (Red Hat) or open-core models. Vercel creates truly open libraries to grow the entire ecosystem. They find that as the overall "pie" grows, their relative slice remains constant, leading to absolute revenue growth.
In a crowded market where startups offer free or heavily subsidized AI tokens to gain users, Vercel intentionally prices its tokens at cost. They reject undercutting the market, betting instead that a superior, higher-quality product will win customers willing to pay for value.
OpenAI has seen no cannibalization from its open source model releases. The use cases, customer profiles, and immense difficulty of operating inference at scale create a natural separation. Open source serves different needs and helps grow the entire AI ecosystem, which benefits the platform leader.
Counterintuitively, a high freemium conversion rate (e.g., 7%) isn't always positive. It may indicate the free plan is too restrictive, failing to build a wide user base that provides network effects, referrals, or a long-term upgrade pipeline. The goal is a broad top-of-funnel, not just quick conversions.
Amplitude's CEO explains how incumbents counter "feature-not-company" AI startups. They rapidly build the startup's core functionality, give it away for free, and leverage it as a powerful lead generation tool for their existing business, commoditizing the startup's value proposition overnight.
Instead of trying to monetize every user, Polly strategically views casual, free creators as 'pollinators.' These users introduce the app into an organization and distribute it widely. This creates top-of-funnel awareness which eventually puts the product in front of high-value 'flowers' (buyers) who will pay.
