There's a sign at Meta's headquarters in Menlo Park. On one side it says Meta. On the other, facing away from the road, it still says Sun Microsystems. When Facebook moved into the former Sun campus, Zuckerberg kept the old logo on the back of the sign as a reminder of what could happen if they stopped innovating.
Last Friday, Salesforce announced that Heroku is entering "sustaining engineering." No new features, and no new contracts. Maintenance mode. We all know what that means.
When I started in tech, Heroku was the platform you used to build new projects. Every startup, every hackathon, every bootcamp ran on Heroku. It was the obvious choice.
What killed Heroku was getting acquired.
More specifically, getting acquired by a parent company whose interests were not aligned with those of its customers. Salesforce bought Heroku in 2010 for $212 million. From the outside, it looked like game over for anyone building in the same space. Who competes with Salesforce's resources?
The truth though, was that Salesforce bought Heroku as a cross-sell tool for their enterprise accounts. Tod Nielsen, Heroku's CEO from 2013 to 2016, said Salesforce "did a great job of expanding Heroku within corporates," but "what they gave up was all the 'cool kid' innovation." The small developer, the person who actually made Heroku what it was, stopped being the priority the day the deal closed.
So the platform froze. Docker, Kubernetes, serverless, edge computing… all the latest advances in cloud. Heroku shipped none of it. Then in 2022, they killed the free tier. Every future engineering lead who would've discovered Heroku on a weekend project went somewhere else instead.
Five years after the acquisition, Vercel was founded. Vercel built Next.js, an open-source React framework, then made the platform the natural place to run it. And they kept their free tier. All of the hobbyists, students, startups… Heroku handed them that entire pipeline.
Vercel grew revenue 82% year-over-year through 2025 and recently raised at a $9.3 billion valuation. Over 40x higher than Heroku’s exit value.
When the incumbent in your space gets acquired by a big enterprise company, you can often predict what comes next. The acquirer optimizes for enterprise revenue, the product freezes, the community drifts. And the acquirer doesn't notice for years because the sales machine allows enterprise contracts to keep growing... for a while.
The unlimited resources come with new priorities, and those priorities will slowly pull them away from the thing that made them good.
Heroku is now the logo on the back of the sign. Vercel is well on its way to IPO.
If your biggest competitor just got acquired, it could end up being the biggest opportunity yet.
