I built a tool to show how much ARR you lose to FX fees
Hey HN, I started my career as a finance manager, transitioned into product management, and now I’m building my own products. Back in my finance days, while managing a £6M budget, I uncovered a £15k leak hiding in plain sight: FX fees. Today, I see solo founders making the exact same mistake. I realised most founders are quietly losing 2-5% of their revenue to what I call the Lazy Tax: - Stripe's ~2% auto-conversion fee on inbound revenue, - plus their local bank's ~3% spread when paying for global SaaS tools (AWS, Claude, Ads). So I built FixMyFX to show founders their exact leak and how to…

What it does
Stop paying the Lazy Tax on your revenue. Calculate your FX loss in 3 clicks.
How much do you lose to FX fees? Most founders* get charged FX fees twice: on income and expenses. Use the FixMyFX calculator to see exactly how much you could save. *If your company, clients, and suppliers are all in the same country, you probably don't need this. Includes Stripe's 1-2% auto-conversion fee on revenue + your bank's ~3% spread on foreign spending. Assumes using a multi-currency account to receive funds (0% fee) and paying foreign expenses from balances. Cost shown is ~0.4% conversion fee on the net profit only. 1. Open a multi-currency account to match your income (EUR/GBP/USD etc). 2. Connect this to Stripe so you get paid in the original currency (skipping FX fees). 3. Pay…from fixmyfx.com

Hey HN: I'm Kaveh, the founder of Usage (https://www.usage.ai/) We help companies drive down AWS costs. Why? Because the way it's done now is a pain. Stakeholders, especially engineers, are required to spend unnecessary time manually finding underutilized or overly expensive EC2s. We believe the optimization process should be done automatically through a series of sophisticated algorithms. At the moment, there are over 70,000 AWS EC2 prices - doing that manually just won't scale at most organizations. My background is in software engineering. Previous to founding Usage, I…
I was laid off, so I built a NerdWallet for startup equity liquidityMar 2026 · strikerates.com · ▲9I was a software engineer at a late stage startup and was caught in a layoff this January. When I looked into exercising my options or getting liquidity, I realized the secondary market is a total black box. Liquidity funds spend a fortune on Google Ads just to find people like us. Those high marketing costs eventually come out of our pockets in the form of higher fees and worse terms. I built StrikeRates to change that. The site is meant to be a central resource for anyone navigating this. I included a Liquidity 101 section that explains the different financial vehicles because that…

Mochi AnalyticsJul 2026 · mochianalytics.com · ▲17Hey everyone, I wanted to see if I could build something like DataFa.st myself, so I made MochiAnalytics. I'm pretty happy with how it's turning out. It’s got all the bells and whistles a small team or solo founder would need to track campaigns and to see which channel is driving revenue. It’s a cheaper analytics tool for side projects, indie hackers, and small apps. I honestly wish I could make it free, but it still needs servers, a database, and a backend to keep event ingestion running 24/7, so there are real costs behind it. I’m still working on it and will keep adding more features…

For years, I have struggled to understand my cash flow and save for the future. In addition to that, my wife has many credit cards and accounts that complicate matters. I am building a tool that connects all our accounts, helps us create a budget, and tracks and adjusts expenses on the fly. I am also sprinkling some AI magic on it for financial suggestions. I am looking for feedback on the implementation. More importantly, I am looking for more beta testers to improve the product.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
