AI Systems Age Faster Than We Expect

Here s something that surprised us.

AI systems don t just run, they age.

Are the best startups built on boring problems?

I came to exactly the same conclusion that real startup ideas often come from simple and boring problems. From my own experience: I spent three years on a startup that was supposed to revolutionize online education, but in the end it had 0 users. Now I ve just started solving a simple problem for home appliance repair technicians and immediately got my first paying users on a very rough MVP.

Thanks for #1 - here's what's next

Hey everyone - we re tremendously grateful for our fantastic launch yesterday, ending at #1 for the day. Thank you all for your support!

I started Tonkotsu because I saw a huge opportunity for a complete rethink of AI coding not just incremental adjustments to established tools and workflows. Having managed teams of hundreds of engineers at Meta, Microsoft, and Atlassian, it s been fascinating to me to find that the role of the developer has shifted overnight: you're now the manager of a team of agents. We're building Tonkotsu to help you succeed in that new role.

What's the best AI model for coding?

New AI models pop up every week. Some developer tools like @Cursor, @Zed, and @Kilo Code let you choose between different models, while more opinionated products like @Amp and @Tonkotsu default to 1 model.

Curious what the community recommends for coding tasks? Any preferences?

Remember: You are the one holding the key to your decisions, not AI.

Since the AI era started booming, everything has been changing incredibly fast and it requires us to adapt just as quickly. AI is now part of both our work and daily lives. It slowly seeps into everything, and over time, it can even reduce how much we think and decide for ourselves.
Of course, I won t deny the huge benefits AI brings.

But the more I saw how easily we can get carried away by it, the more I felt the need to slow down to step back and look at the bigger picture.

After spending time working with AI, I realized a few important things:

Hi! OpenAI's first hire for the London office, now founding something new for AI comms 👋

Hi Product Hunt!

I m Doug, co-founder and CEO at Lightfern. We re based in London and currently in stealth, building something that focuses on delivering human authenticity in communication, whilst still enhancing it with AI.

I was previously at OpenAI as their first hire for the London office, and worked at Facebook for over a decade. I led researchers that trained GPT-4o and built many of Facebook s core privacy and messaging features.

Can a large Product Hunt community help you with a product launch?

This is something I ll find out in just a short while, one week from now (Jan 28), as I m about to re-launch a digital detox app. If you want, follow, maybe you will be on watch of my steps and activities

However, that s not the main point of this post.

How likely is AGI in the next five years? A look at money vs. science

I came across Deutsche Bank s latest report on AI, and it sparked an interesting thought experiment: how likely is it that we ll see AGI (AI that thinks and learns like a human) within the next five years?

The report highlights a fascinating divergence: the view from money vs. the view from science.

  • Money: the probability inferred from trillions poured into data centers, Nvidia chips, and servers. Investors seem to be betting that AGI is inevitable.

  • Science: the probability inferred from research papers and AI development models. Experts are far more cautious, suggesting the realistic probability is only 20%.

Are there benefits to being personal with customers anymore or has everything become transactional?

There are countless products and services out there, and I ll admit I sign up for more than I probably should. But I usually stop using them for a few common reasons:

  1. It doesn t actually fit my needs

  2. The company feels unreliable or opaque

  3. The value doesn t justify the cost

After spending my career in enterprise software, I ve noticed that many of these issues aren t just product problems, they re relationship problems.

When companies show a bit of intention, clarity, and care, trust goes up. When they don t, everything feels disposable, even good tools.

2 weeks before the product launch. What am I doing in terms of preparation?

Not really much, and it annoys me a bit. In exactly 14 days (28. 1.) we will launch the product, and the only thing I do is talk about it.

But yes, there are points that I still want to master by then, e.g.:

  • Create an informational newsletter inviting people to follow our product page

  • Create a list of people who could support us and ask them for help

  • Announcements on social networks

  • Inform Kickstarter backers who supported us with updates this is also an audience

  • Publishing a Product Hunt badge on the landing page

  • Continually grow and maintain a personal brand which should be a long-term goal, not just for launch purposes.

Reverse-engineering Cursor's recent Product Hunt launches

Last month, Cursor launched for the fifth time on Product Hunt in 2025.

The 2024 Product of the Year [1] still hits the charts. They have launched web and mobile agents, a visual editor, and 2.0, consistently ranking in the Top 5 Products of the Day.

Post-launch thoughts after reaching Top 10 on Product Hunt

Hey everyone,

After launching Intrascope and finishing Top 10 Product of the Day, we wanted to open a quick discussion.

The biggest takeaway for us wasn t the ranking, but the conversations. We talked to teams who are already using AI daily and are struggling with scattered tools, separate API keys, lost context, and costs growing without visibility.

That s exactly why we built Intrascope: a shared AI workspace where teams bring their own API keys, work with shared context and Manifests, and keep usage and costs predictable.

How can I use your product?

We at xPay (YC W24) are looking to optimise in Sales, CRM, marketing, Product, Analytics etc and would love to know more products across PH for us to try!

Suggest some names!!

What makes you decide not to try a product?

There are plenty of tools that seem useful on paper, yet something makes us close the tab instantly.

Sometimes it s pricing, sometimes messaging, sometimes the onboarding feels unclear.

Often it s a gut feeling that s hard to explain.

First-time maker (Solo Dev). Launching Sunday and terrified!

Hi everyone,

I've been a lurker here for a while, but I'm finally taking the plunge and launching my first solo project this Sunday (Jan 11).

It s a simple private movie and series logger. I built it because I got tired of the ads on IMDb and the social pressure of other apps. I just wanted something mindful that was for me, not for likes.

Since I m doing this completely alone with $0 budget, I m pretty nervous about the 'Launch Day' chaos.

Why Agents Will Unseat More Incumbents Than Social Ever Did

Hey all,

15 years ago I wrote an article about the rise of a more social web for Huff Post.

What made you choose the company/product you’re building today?

At the beginning, my reason was very simple: I needed a job and I genuinely liked the product.

I graduated with a Marketing degree, but I never felt like I belonged in agencies or similar environments. It just wasn t for me. At the same time, I didn t have much experience in tech either. So I took a leap of faith and applied for a Customer Support role, almost blindly.

The early days were tough. I had no technical background, no real understanding of how apps were built, and everything felt overwhelming. But the product itself became my motivation. I started from the most basic things: learning simple technical terms, understanding how an app is structured, and slowly exploring how everything works behind the scenes.

What new job position rise do you see in upcoming years?

LinkedIn officially shared the job titles that started appearing more often, and with the rise of AI, the market is restructuring.

The actual top 10 roles that have seen the biggest rise in listings (in the U.S.) are:

  1. AI engineers Engineers developing and implementing AI models that perform complex tasks

  2. AI consultants and strategists - Helping organisations plan and implement AI technologies to improve operations

  3. New home sales specialists Which sounds like a rebranding or real estate agent

  4. Data annotators Labelling and reviewing data for AI projects

  5. AI/ML researchers Designing new AI models and systems

  6. Healthcare reimbursement specialists Ensuring healthcare providers are getting correct and timely payments

  7. Strategic advisors and independent consultants Which seems like a pretty broad-ranging segment

  8. Advertising sales specialists You re reading a marketing blog, I assume you know this one

  9. Founders Not sure this can be listed as a job title in itself, but LinkedIn s keen to highlight how people are shifting to their own businesses

  10. Sales executives

Is “US-first” still the right default for AI products?

With today s tools, translation (UI, copy, even video) is no longer the hard part.

What slows us down instead are things like tax, legal compliance, hiring, support, payments sometimes even geopolitics. The moment users show up from a new country, a product problem turns into an operating one.

Do you think the 9-9-6 work culture is right?

Yesterday, I came across a job posting from a specific SF company that offered Yesterday I came across a job posting from a specific SF company that offered a salary of 250k 1M (including equity), but realistically, I don't think they have that money; they're just grinding to satisfy investors and succumb to too much hustle culture.

Requirement: be available on-site from 9 AM to 9 PM 6 days a week in the office (and I bet even Sunday would be dedicated to meeting some team members in "free time"). In addition, they were willing to hire those who would relocate to SF.
