The last year has seen an incredible impact as the result of AI working its way into everything we do. Now, you just need to be able to describe an investing hypothesis and we'll turn it into testable quantitative strategies that you can deploy and execute.

11 years ago my co-founder and I launched Pacifica — a mobile app for stress, anxiety, and depression.
At its peak, over 4 million people downloaded it.
Last month, it quietly disappeared from the app stores. I didn’t know it was happening, and I was more emotional about it than I expected.
It reminded me how early startups are obsessed with real people and real problems and how that focus can change as companies grow.
No big lesson. Just gratitude for what it meant while it existed.

Bear case:
• Tanker rates are cyclical — 30% on spot
• $1.9B debt (1.1x D/E)
• Petrobras concentration risk
• Energy transition headwind
• Shipping stocks always trade below NAV for a reason

If you want to build your own factor models and test them against historical data, that's what we built Accountable Finance for. Direct indexing with backtesting across different factor combinations.
DM me if you want a gift code to try it out.
