How it works

01

Connect your positions

Link your brokerage or manually add tickers. Postbell maps your entire portfolio, including crypto, ETFs, and individual stocks.

02

AI analyzes overnight

While you sleep, Postbell scans earnings calls, analyst reports, macro data, and news. It filters noise and finds what matters to your holdings.

03

Morning brief, delivered

Wake up to a concise, actionable brief. No dashboards to check. No feeds to scroll. Just the signal, personalized to your portfolio.


Position-aware analysis

Every insight is filtered through your actual holdings. Postbell doesn't report on the market. It reports on your money.

Earnings autopilot

Automatically monitors earnings season for your holdings. Summarizes results, guidance changes, and analyst reactions before the market opens.

Thesis tracking

Define your investment thesis for each position. Postbell flags when reality diverges from your assumptions, so you can act on conviction, not emotion.

Rebalancing signals

Tracks portfolio drift and alerts when positions deviate from your target allocation. Clean signals, no noise.

Stop checking dashboards.
Start reading briefs.

The best investors don't stare at screens all day. They have analysts who distill the noise into signal. Postbell is that analyst, working every night, delivering every morning.
