The revenue trends in the tech sector are telling very different stories right now, and two names stand out for heading in almost opposite directions.

On one side, AppLovin has been riding an impressive growth wave, supercharged by artificial intelligence applied to in-app advertising.

On the other, Fastly, a well-known name in edge computing and content delivery, is still trying to find its groove in an increasingly competitive market.

But why does this matter right now? Because comparing these two companies goes way beyond looking at numbers on a spreadsheet. It opens a window into understanding how the tech market is reshaping itself, which bets are paying off, and where real challenges still need to be overcome.

In the next sections, we dive into the data, the business model of each company, and what it all says about where the sector stands today 🚀

AppLovin: when AI becomes the revenue engine

AppLovin is not exactly a new name, but over the past few years the company has gone through a transformation that very few have managed to replicate with the same efficiency. Founded in 2012, it started as a marketing platform for mobile app developers, but it was the heavy bet on artificial intelligence that completely changed the game. The core of that shift is called AXON, the company’s proprietary recommendation engine that uses machine learning to connect advertisers and users in real time with a level of precision that simply impresses the market.

The direct impact of this technology on financial results is undeniable. AppLovin reported total revenue that surpassed Wall Street analyst expectations repeatedly over recent quarters, with accelerated growth compared to prior periods. The company’s software segment, which is exactly where AXON operates, posted profit margins significantly higher than the legacy gaming segment. That led the company to make the strategic decision to sell its game studios division and focus exclusively on the advertising platform. It was one of the most talked-about moves in the sector and continues to spark debate about the future of the model.

What makes AppLovin’s trajectory especially relevant for understanding tech trends is the clarity of its thesis: using AI not as a marketing differentiator, but as the actual backbone of the product. While many companies are still talking about integrating artificial intelligence into their processes, AppLovin has already built its entire revenue engine on top of it. And the numbers show that this bet, at least for now, is working really well. The company’s market cap has skyrocketed, and it has started being compared to much bigger names in the digital advertising ecosystem, like the Trade Desk and even the ad divisions of major big tech companies.

Why AppLovin’s model gets so much attention

One detail that a lot of people miss is just how scalable AppLovin’s business model really is. Since AXON is an automated system that learns on its own with every interaction, the more data it processes, the better campaign performance gets. This creates a positive snowball effect: more advertisers bring in more data, more data improves results, and better results attract even more advertisers. It is this kind of dynamic that makes investors see potential for sustained growth, not just a temporary spike.

Fastly: real potential, growth that hasn’t taken off yet

Fastly is a company with a pretty solid technical proposition. Specializing in edge computing, it offers a content delivery network, or CDN, along with security services and edge computing capabilities that allow applications to run closer to end users, reducing latency and improving the overall experience. On paper, it is exactly the kind of infrastructure that an increasingly connected and demanding digital world needs. In practice, though, the company has struggled to translate that technical relevance into consistent revenue growth.

Fastly’s most recent financial results showed more modest growth, hovering around low single digits in percentage terms, which is below what the market expected for a company of its size and with the narrative it carries. The company has been facing pressure from strong competitors like Cloudflare, Akamai, and even the CDN and edge divisions of the major cloud providers like AWS, Google Cloud, and Azure. This competitive environment has made it tough for Fastly to expand its customer base at the pace needed to justify higher valuations, and that has been reflected in how the stock has performed over time.

Still, it would be a mistake to underestimate what Fastly represents within the tech ecosystem. The company has contracts with some of the most relevant brands on the internet, and its edge security platform, especially its WAF (web application firewall) solution, has received positive feedback from the enterprise market. Its challenge is much more about execution and positioning than about technical capability. If the company can better communicate its unique value and expand into new segments, like AI inference at the edge, it could surprise people. But that is still in the realm of possibilities, not certainties.

The weight of competition in Fastly’s game

It is worth remembering that the CDN and edge computing market is fiercely contested. When the big cloud players enter a segment in full force, offering bundled packages at aggressive prices, more focused companies like Fastly need to chase after clear differentiators to avoid becoming just another option on the list. That is why many analysts keep an eye not only on Fastly’s revenue but also on the quality of the contracts it renews and its ability to keep major customers loyal over time.

What the numbers reveal about the tech sector

Placing AppLovin and Fastly side by side is a very effective way to understand how the tech market is distributing value right now. Companies that can show accelerated revenue growth with expanding margins and an AI-differentiated product are receiving much more generous valuation multiples than infrastructure companies growing at a slower pace, even if they are technically relevant. This is not a value judgment about which company is better, but it is a real data point about how the market is pricing innovation at this moment.

AppLovin, for example, trades at price-to-earnings multiples that put it in the high-growth category, something that would have been hard to imagine two years ago for a mobile advertising platform. Fastly, on the other hand, operates at much more compressed levels, reflecting investor uncertainty about when and how growth will pick up. This difference in perception between the two is an interesting barometer for what the market is valuing right now: having good technology is not enough — you need a business model that turns that technology into revenue in a scalable and predictable way.

Another point worth highlighting is the issue of revenue concentration. AppLovin has a significant dependency on the mobile app ecosystem, especially gaming, and any change in platform privacy policies, like Apple’s iOS updates, could directly impact AXON’s performance. Fastly, in turn, has a more diversified customer base across segments, but with churn risk — meaning customer loss — that needs to be closely monitored. These vulnerabilities are important for any honest analysis of both trajectories.

A lesson that applies to the entire sector

At the end of the day, the contrast between these two companies teaches something that applies to virtually any digital business: having good technology is just the starting point. What truly separates those who grow fast from those who stall out is the ability to turn that technology into recurring and predictable revenue. Investors value predictability just as much as they value innovation, and when those two things move together, the results tend to show up in market value.

Tools we use daily

The picture that AppLovin and Fastly represent is a microcosm of something much bigger happening in the tech sector. Artificial intelligence is redefining which types of businesses can grow fast and which get left behind — not necessarily because of a lack of quality, but because they are not positioned in the layers the market is valuing the most right now. Companies that use AI to directly improve monetization, like AppLovin does, tend to see that value reflected more immediately in financial results and investor sentiment.

On the flip side, infrastructure companies like Fastly could benefit enormously from AI growth in a second wave, since large language models and generative AI applications need low latency, robust security, and edge computing to work well at scale. Edge computing might be exactly what fuels the next generation of production-grade AI applications, which would put Fastly in a much more strategic position than it appears to be in today. The question is whether the company will be able to execute well enough to capture that moment when it arrives.

What becomes clear from analyzing these two trajectories is that revenue trends in the tech sector have never been so dynamic and, at the same time, so revealing about what truly matters for scaling a digital business. Sustainable growth, healthy margins, and a product that uses cutting-edge technology to solve real problems in a scalable way remain the most powerful formula. AppLovin and Fastly, each in their own way, are two important chapters in a story that is still being written 📊
