'''# The Most Underrated AI APIs That Give You a Competitive Edge
I remember back in the early days of RemoteTeam, we were scrappy. We had to be. We were up against giants, and our budget was a fraction of theirs. We couldn't afford to just throw money at problems. We had to be smarter. We had to find the arbitrage opportunities in the market. And we found one in an obscure API that nobody was talking about.
That one API allowed us to build a feature that our competitors didn't have, and it cost us next to nothing. It was our secret weapon. It was our competitive edge. And it's a lesson I've carried with me ever since.
Everyone is talking about the big AI players. OpenAI, Anthropic, Google. And yes, they are powerful. I'm an investor in some of them. But they are also expensive. And when you're a startup, every dollar counts. Your Customer Acquisition Cost (CAC) is your lifeblood. You need to get it as low as possible, or you'll bleed out before you even get started.
That's why I'm writing this. To tell you about the underrated AI APIs. The ones that can give you a competitive edge without breaking the bank. The ones that can help you build a better product, faster, and for a fraction of the cost.

Beyond the Giants: Finding Your Niche
When I was building MovieLaLa, we were obsessed with understanding what made a movie trailer go viral. We analyzed everything. The music, the editing, the shots, the colors. We even tried to predict which trailers would be hits. We were basically doing manual AI.
If only we had something like AssemblyAI back then. It's an API for speech-to-text, but it does so much more. It can do sentiment analysis, summarization, and even topic detection. It's a goldmine for anyone working with audio or video data.
Imagine you're building a podcasting app. You could use AssemblyAI to automatically transcribe all your episodes, making them searchable. You could use it to identify the most popular topics and create highlight reels. You could even use it to analyze the sentiment of your listeners' comments and get real-time feedback.
And the best part? It's a fraction of the cost of the big players. That's the kind of arbitrage I'm talking about. Finding a tool that's just as good, if not better, than the expensive alternative, and using it to your advantage. '''
The Power of Open Source: Hugging Face
I'm a huge believer in open source. It's the great equalizer. It allows anyone, anywhere, to build amazing things. And when it comes to AI, Hugging Face is the king of open source.
For those who don't know, Hugging Face is a platform for sharing and using open-source AI models. It's like GitHub for AI. You can find models for everything from text generation to image classification to audio synthesis. And you can use them for free.
Now, you might be thinking, "But Sahin, I'm not a machine learning expert. I don't know how to use these models." That's the beauty of Hugging Face. They have a simple API that makes it easy to use any of their models. You don't need to be a PhD to build powerful AI features.
I have invested in so many companies that have built their entire business on top of Hugging Face. They've built everything from AI-powered writing assistants to code generation tools to customer support bots. And they've done it all with a tiny team and a shoestring budget.
That's the power of open source. That's the power of Hugging Face.
Don't Reinvent the Wheel: Specialized APIs
One of the biggest mistakes I see founders make is trying to build everything from scratch. They think they need to build their own AI models, their own infrastructure, their own everything. But that's a huge waste of time and money.
There are so many amazing companies out there that have already solved these problems. And they offer their solutions as simple APIs. Take for example, a company I invested in that is in the legal tech space. They were trying to build their own AI model to analyze legal documents. It was taking them forever, and it wasn't even that accurate.
I told them to stop. I told them to use a specialized API. They found one that was specifically designed for legal document analysis. It was more accurate, faster, and cheaper than anything they could have built themselves.
That's the power of specialized APIs. They allow you to focus on what you do best, and leave the rest to the experts. Don't reinvent the wheel. Find the best tool for the job, and use it.
The Takeaway: Be a Scrappy Underdog
Look, the AI space is moving at a dizzying pace. It's easy to get caught up in the hype and think you need to be on the bleeding edge, using the most expensive, most powerful models to compete. But that's just not true.
Some of the most successful companies I've invested in, the ones that went from nothing to multi-million dollar ARR in a few years, were the scrappy ones. The underdogs. The ones who were smart about their resources and found those little pockets of opportunity that everyone else was overlooking.
Your competitive edge isn't going to come from having the biggest budget. It's going to come from your ingenuity. It's going to come from finding those underrated, overlooked tools and using them in creative ways to build something new, something better.
So go out there and be scrappy. Find your secret weapon. Build something amazing. And don't let anyone tell you that you can't compete.
Frequently Asked Questions
What's the most common pushback you get on this?
People often push back by citing exceptions or edge cases. And they're usually right that exceptions exist. But building a strategy around exceptions rather than patterns is a losing game for most founders.
What experience informs this perspective?
This perspective comes from over a decade of building companies in Silicon Valley, two successful exits (RemoteTeam to Gusto, MovieLaLa to Gfycat), and investing in 200+ startups including Anthropic, OpenAI, and Scale AI. I write about what I've lived.
How has this view evolved over time?
My thinking on most topics has changed significantly over the years. Early in my career, I held many conventional views that experience proved wrong. I try to update my beliefs when the evidence changes.
