Ask HN: Founders/investors, what AI bet you made in 2022 and how it is going?

kjok — Wed, 08 Apr 2026 18:06:18 +0000

In 2022, many founders and investors made strong bets on AI: new companies, pivots, or funding theses. Now that we have had time to see what actually played out, what did you bet on and how is it doing today? We learn a lot from failure, so especially interested in (and would appreciate) honest stories about what did NOT work and why.

How do you know that they were LLM scrapers? The reason I ask is because user agents could easily be spoofed?

For those who have deployed Cloudflare in front, what are pros and cons? How's the user experience? Do they offer free bot protection?

How are you measuring this? Does your solution rely on user agent or device fingerprinting? Curious to know what tools are available today and how accurate they are.

Thanks for sharing your approach!

> It is nothing special. We keep X number of machines in a warm pool.

I'd love to better understand the unit economics here. Specifically, whether cost is a meaningful factor.

The reason I ask is that many startups we've seen focus heavily on optimizing their technology to reduce cold/boot startup times. As you pointed out, perceived latency can also be improved by maintaining a warm pool of VMs.

Given that, I'm trying to determine whether it's more effective to invest in deeper technical optimizations, or to address the cold start problem by keeping a warm pool.

> The problem is that those underlying frameworks can very easily be misconfigured.

Agreed. I'm sure a number of these sandboxing solutions are vibe-coded, which makes your concerns regarding misconfigurations even more relevant.

> There are dozens of projects like this emerging right now. They all share the same challenge: establishing credibility.

Care to elaborate on the kind of "credibility" to be established here? All these bazillion sandboxing tools use the same underlying frameworks for isolation (e.g., ebpf, landlock, VMs, cgroups, namespaces) that are already credible.

And this is exactly why we see noise on HN/Reddit when a supply-chain cyberattack breaks out, but no breach is ever reported. Enterprises are protected by internal mirroring.

I mean that agents can scan the code to find anything "suspicious". After all, security vendors that claim to "detect" malware in packages are relying on LLMs for detection.

Curious to know why are coding agents not detecting such risks before importing dependencies?

This gives me an impression that the paper has already been published and is available publicly for us to read.

I understand the need, but I don't understand why a VM or Docker is not enough. Why are people creating custom wrappers around VMs/containers?

Genuine question: why is everyone rolling out their own sandbox wrappers around VMs/Docker for agents?

And how often does this happen? Do you have any proof? Most YC companies building browser agents have built-in captcha solvers.

If not today, models will get better at solving captchas in the near future. IMHO, the real concern, however, is cheap captcha solving services.
