I've made this tool called the Cash Flow risk simulator, from the very obvious name you can tell what it does, it basically takes simple financial records whether tangible or intangible, and quantifies the probability of failure. As a business owner the thought of your business failing is always something that looms overhead of founders alike. With my tool you can better understand the risk of failure, how much runway you have, and how to optimize for the lowest chance of failure. The product is still in beta and feedback on my software would be much appreciated. The link for the product will be in my profile if anybody would like to test the early stages of a much bigger vision.

From what I am seeing across communities, here is what the tool stack looks like right now.

The Core Stack

Email & Capture: Mailchimp for launch updates and email sequences . Carrd for quick, clean launch-specific landing pages . Pre-launch tools like LaunchBuddy and Prefundia to build a waitlist and gather early feedback before you even hit the Product Hunt button .

Social & Scheduling: Buffer or Hootsuite to keep a consistent presence across X, LinkedIn, and Threads without it taking over your entire day . Canva for generating graphics that do not look like you threw them together in five minutes .

Hey Product Hunt. I'm Matthew, founder of Protonyx LLC.

I'm a junior in high school in St. Louis, and I've spent the last year building Vector, a portfolio analytics desktop app for self-directed retail investors.

I launched RFP Copilot today.

It s a decision engine for teams that review RFPs, RFQs, grants, bids, procurement opportunities, and similar revenue opportunities.

Hey Product Hunt!

We ve all been there: you look at your bank account and see a charge, but you can't tell if it s a subscription you forgot about or just a grocery run. Tracking bills shouldn't be that annoying!

So, we built Recurring Charge to fix this.

It automatically separates your regular shopping from your actual recurring bills like monthly software, gym memberships, or bi-monthly invoices.
Even more with Lums AI

We re launching R0Y in 9 days.

R0Y is an AI-native financial research studio that lets you build full financial dashboards just by describing what you want.

1. A 3-year search for a simple tool to track both personal and business finances in one place. Nothing fits.

2. Website owners constantly need minor edits in the admin panel. They are forced to pay specialists for 5-minute tasks. We need an AI agent that does this on command in the browser.

3. An indie hacker spends 20-30 hours manually cold launching each new product in directories, Reddit, and blogs. There is no tool that fully automates this and proves its effectiveness.

4. A freelancer often loses in proposal competitions due to the inability to quickly create personalized and visual website concepts for each job order.

5. A Telegram channel owner is losing their audience without understanding the reasons for unsubscriptions. There is no simple tool for automatically collecting feedback from departed subscribers.

I'll start.

Supabase. Found it here three years ago. Thought it was just another backend. Now I can't imagine building without it.

Here's what it does for us at Rankfender:

Auth that doesn't make you crazy. We have users across 120+ countries. Supabase handles sign-ups, logins, password resets, magic links, OAuth with Google and GitHub. It just works. We didn't have to build any of it.

Every year I reflect on how I spent money in the previous year. Previously, I have manually scraped my bank statements and put together a report, but 2025 was interesting because I built a fairly overkill personal finance product to make this report easy to generate for myself.

Because it is really easy, I m going to do a deep dive on how I spent money in 2025. (I was able to put this all together in ~10 mins)

Hey everybody,

Yigit here! I am developing a personal finance app mainly based on what features I wish an app to have and it is on google play closed test now. Here is a quick summary:
The app's main value proposition is being able to keep track of your expenses 'automatically'. The rationale behind is the fact that in my country banking laws restrict individual's access to open banking apis. That is, you cannot have an API access to your bank to exchange information and keep track of your expenses unless you are corporate. According to my research, this feature is available in US and EU but only with certain restrictions in the latter.

I thought it could be sutaible time to ask the community about their needs about such an app and can guide me a long way before I commit further. Would you be so kind enough to answer below questions? Any replies are appreciated and thanks in advance.

1. Do you use personal finance app?

2. Could you please share your the most essential must-have features of the personal finance app of your choise and tell me why?

3. Under which circumstances would you give another app a try?

4. What would be the ideal price point for such a service in your perspective?

Just asking, QuickBooks? Google Sheets? Something you hacked together with AI?

We built a very simple AI-driven tool and want to hear what s working (or not) for early-stage teams.

Over the past few years, I ve ended up with a scattered stack of tools domains, SaaS subscriptions, plugins, licenses, hosting, etc.

Some are in Google Keep, some in emails, and others I forgot I even signed up for.

I m curious how do you track everything you ve purchased for your projects or startup?

• Do you use a password manager?

• Manual spreadsheet?

• Some kind of custom-built dashboard?

This is a small test of your financial literacy and entrepreneurial mindset. :)

The art is mostly about making the most of the least, so share your approach to situations where you have to be creative.
