Quick background: I used to code. Studied it in school, wrote some projects, but eventually convinced myself I wasn't cut out for it. Too slow, too many bugs, imposter syndrome — the usual story. So I pivoted, ended up as an investment associate at an early-stage angel fund, and haven't written real code in years. Fast forward to now. I'm a Buffett nerd — big believer in compound interest as a mental model for life. I run compound interest calculations constantly. Not because I need to, but because watching numbers grow over 30-40 years keeps me patient when markets get wild. It's basically…

Hello - I’m the founder of Frec. We built a direct indexing product that lets you tax loss harvest the S&P 500 or the S&P Information Technology indexes for a low 0.10% fee and a minimum deposit of $20k. You can start your direct index with cash or contribute stock you already have. Our historical simulations based on 20-years of data show that we harvest ~40% of every deposit back in capital losses over a period of 5 years. I linked to a live demo account with a real $50k deposit made on Dec 5, 2023. The account shows that our trades track the S&P very closely. As of January 21, our direct…

Burned about 1 weeks on this. Not sure if it's useful to anyone beyond my original use case, but figure I'd share. Friend went through a nasty divorce. Had $750k going into the marriage (inheritance), put it in a joint account like an idiot. Five years later, account's been up and down, money mixed with paychecks and mortgage payments. Lawyer says "you need a forensic accountant to trace what's still yours." Quote comes back: $5k, 4 weeks minimum. I'm sitting there thinking - this is just transaction categorization and some relatively simple math (the "Lowest Intermediate Balance Rule" if…

I was with BOFA and Chase Private Client for years before I realized that they were making tons of interest off my money and just keeping it for themselves. The funny thing is that since I had a lot of money with them they raised my rate as a thank you to wait for it 0.02% instead of 0.01% lol. Got upset because of this and made this site. It scrapes all the banks every 30 minutes so it is the most real time source of APY data on the internet. Rates are now over 3% at the high end so it makes sense to park your money in these places rather than the big three banks.
