Airtable just finished a three-year project that might sound insane to most business owners: they completely rewrote the core database that powers their entire platform. We’re talking about rebuilding the engine while the plane is flying at 30,000 feet, serving 500,000 organizations including 80% of the Fortune 100.
Why would anyone do this? And more importantly, what can your business learn from their decision?
The Performance Problem Every Growing Business Faces
Here’s the situation: Airtable started out serving small teams with modest data needs. Their original database, built in TypeScript (a popular programming language), worked perfectly fine for that scale.
But then they started attracting enterprise customers with massive, complex operations. And more recently, they began integrating AI agents that can read and write data at lightning speed—orders of magnitude faster than humans.
Suddenly, their database wasn’t just handling dozens of requests per minute; it was handling thousands. The old system was groaning under the weight.
Sound familiar? Maybe your business started with a simple spreadsheet, then moved to a basic app, and now you’re hitting walls you never anticipated. Scale changes everything.
The Rust Revolution
Airtable’s solution was to rebuild their database in Rust—a programming language known for exceptional performance and reliability. Think of it like swapping your delivery van’s engine with a Formula 1 racing engine while keeping the same comfortable body.
The results? They can now:
- Process Multiple Requests Simultaneously: Their old single-threaded system could only handle one thing at a time. The new system can juggle dozens of operations in parallel.
- Handle Massive Data Sets: Enterprise customers with tens of gigabytes of data can now work smoothly without slowdowns.
- Support AI-Powered Workflows: As AI agents become more common in business operations, they need systems that can keep up with machine-speed data processing.
- Deliver Real-Time Updates: When one person makes a change, everyone sees it instantly—even in massive, complex databases.
The Business Lessons
You don’t need to rewrite your entire system in Rust (though we can help if you do). But there are crucial lessons here for any growing business:
1. Technology Debt is Real
When you build systems for your current needs, they eventually can’t handle your future growth. Airtable recognized this early enough to invest in the solution before it became a crisis. Many businesses wait until systems are actively failing before addressing the problem.
2. Performance is a Feature
Customers notice when things are slow. They notice even more when things are fast. Airtable’s investment in performance isn’t just technical—it’s a competitive advantage that helps them win and retain enterprise customers.
3. The AI Era Demands Better Infrastructure
If you’re thinking about adding AI capabilities to your business (and you should be), your current systems might not be ready. AI agents can hammer your infrastructure with requests faster than any human could. You need systems built for that reality.
4. Strategic Modernization Pays Off
Airtable spent three years on this project—three years of investment while continuing to ship new features and serve customers. That’s strategic thinking: investing in the foundation that will power the next decade of growth.
What This Means for Your Business
Most small to medium businesses aren’t running systems at Airtable’s scale (yet). But the principles apply at any size:
- That custom app you built in 2018? It might be holding you back in 2026.
- That slow reporting dashboard? It’s costing you more than you think in lost productivity.
- That integration that “works fine”? It might break under the weight of your growth plans.
The good news? Modern technology makes it easier than ever to build fast, scalable systems. Languages like Rust, infrastructure tools like Kubernetes, and cloud platforms like AWS provide the building blocks for enterprise-grade performance at startup-friendly prices.
The Optimistic Path Forward
Here’s what excites us about stories like Airtable’s: they prove that investing in your technical foundation pays dividends. Better performance means happier customers, more efficient operations, and the ability to scale without hitting walls.
And you don’t need a three-year project to start seeing benefits. Sometimes it’s as simple as:
- Migrating that slow legacy system to modern infrastructure
- Rebuilding a critical API to handle 10x the traffic
- Optimizing your database queries to reduce page load times by 80%
- Setting up proper monitoring so you catch problems before customers do
The companies that win in the long run are the ones that treat their technology as a strategic asset, not just a cost center.
