How do you pick an ad network for DeFi startups?

[justify]Lately I’ve been spending a lot of time around small crypto and DeFi projects, and something I kept hearing was the same question again and again: how do you actually choose the right  ad network for a DeFi startup ? It sounds simple at first, but once you start looking around, there are way more options than you expect.Some networks claim they specialize in crypto traffic, others say they’re great for startups, and a few just promise huge reach without explaining much else. As someone who has tried helping a couple of early-stage projects get visibility, I realized picking the wrong network can waste both time and budget.

The confusing part most people run into
One of the biggest problems is that DeFi startups are not exactly like regular tech startups. The audience is niche, the rules around advertising can be tricky, and a lot of mainstream ad platforms are still cautious about crypto-related promotions.I remember one team I was chatting with tried running ads on a very popular platform that works great for normal apps. The problem? Their campaigns kept getting restricted or flagged because the system didn’t really understand DeFi products.That experience made me realize something: not every ad network is built with crypto or DeFi in mind. Even if the platform works well for e-commerce or SaaS companies, it doesn’t mean it will perform well for blockchain projects.

What I started paying attention to
After watching a few projects test different platforms, I noticed that the most important thing isn’t just traffic size. It’s actually relevance. If an ad network already works with crypto websites, blockchain blogs, or Web3 apps, the chances of reaching the right people are much higher.Another thing I started looking at was targeting options. DeFi users often hang out in very specific corners of the internet. So if the ad network allows targeting by crypto interest, blockchain content, or similar communities, that’s usually a good sign.Budget flexibility also matters more than people think. Startups rarely have huge marketing budgets in the beginning. Platforms that allow smaller test campaigns make it easier to experiment without risking too much money upfront.

Something that helped me understand the space better
While trying to figure all this out, I ended up reading through a few guides and discussions online. One page that actually explained things in a pretty simple way was this breakdown of the best ad network for DeFi startup. It helped me understand how crypto-focused ad networks work differently compared to regular ad platforms.What stood out to me was the idea that crypto ad networks already have publishers and audiences who are comfortable with blockchain topics. That alone removes a lot of the friction that DeFi startups face when advertising on more traditional networks.

My personal takeaway after watching a few projects try
If I had to sum up what I’ve learned from watching different teams experiment, I’d say this: don’t rush into the biggest ad network just because it’s popular. Instead, look for platforms that already understand crypto audiences.It’s also worth starting small. Run a few test campaigns, see where the clicks actually come from, and check whether the traffic engages with your product. Some teams discover that a smaller crypto-focused network performs better than a giant platform that brings random traffic.Another helpful trick is simply asking other founders or marketers in the crypto space what worked for them. The Web3 community is surprisingly open about sharing their experiences, especially when it comes to marketing challenges.

Curious what others here have tried
I’m still learning myself, so I’m really curious how others here approach this. Have you found a specific ad network that works well for DeFi startups? Or did you end up testing several before finding something that actually brought real users?It feels like this is one of those things where real experiences matter more than marketing promises. So if you’ve run campaigns for a DeFi project, I’d love to hear what worked and what didn’t.[/justify]
