Founding-member waitlist · open now
The morning briefing that knows what you own.
Readthrough scans thousands of headlines, filings, and macro prints overnight — then tells you what they mean for your portfolio, in a 15-minute read. Not the market. Yours.
Free two-week trial for founding members. One email when your spot opens — nothing else.
- Built on primary sources

Rate-cut odds firmed overnight. Six of your holdings that sold off on the July payroll shock have now round-tripped the move.

The problem
Your news feed doesn't know your portfolio.
Retail investors get two bad options. Free news is a keyword-matched firehose — hundreds of items a day, none of them explaining what an event means for what you actually hold. Professional tools answer that question, but at $2,000+ a month, built for institutions.
The result is the “so what?” gap: everything tells you what happened; nothing tells you what it means for what you own — especially when the connection is indirect.
How it works
From your holdings to your briefing.
Tell us what you hold
Enter your tickers — any US-listed stock. No brokerage login, no keys to your money. Read-only broker sync comes later, and stays read-only.
We map your portfolio
Readthrough builds a knowledge graph of each holding — its customers, suppliers, geographies, and macro sensitivities — straight from SEC filings, in minutes. It refreshes itself every earnings cycle.
Read 15 minutes a day
Every morning: what moved, why, and what it touches in your portfolio — with a bull and a bear take on every catalyst. Noise never reaches you; quiet days get a short note, not filler.
Interactive demo
Type your tickers. Watch it build.

Your portfolio graph
Why it's different
One headline. Three of your holdings.
Keyword alerts only fire when a story names your ticker. But most of what moves your portfolio never mentions it. Because Readthrough knows how your holdings are wired together — who supplies whom, who competes with whom — a single headline routes to every position it actually touches.
That's the difference between reading the news and understanding your exposure.
- CLS▲ Named Meta supplier — buildout is first-order demand for your Celestica.
- AMD▼ An in-house chip is substitution risk for your AMD's data-center GPUs.
- IREN▼ Meta compute expansion competes with your IREN's AI-cloud capacity.
Notice the headline never names CLS, AMD, or IREN.
Radical grounding
We never print an unverified number.
Sourced and dated
Every figure in every briefing carries its source and observation date. If we can't verify a claim, we omit it or flag it — we don't guess.
Filings, not vibes
Your portfolio graph is built from what companies disclose to the SEC — customer concentration, supplier dependencies, geographic exposure — not from social-media sentiment.
Primary sources only
No rumors, no reposts — the graph is built from the record.
Silence is a feature
Events are triaged on a 1–5 materiality scale. Levels 1–2 never reach you. A quiet day produces a short note, never manufactured urgency.

Questions
Fair asks.
Is this investment advice?
No. Readthrough is news and analysis — no buy/sell recommendations, no price targets of our own, no suitability claims. We tell you what happened and how it connects to what you hold. What you do about it is yours.
How is this different from Google Alerts or my broker's news tab?
Those match keywords: a story must name your ticker to reach you. Readthrough routes news through a structural map of your holdings' customers, suppliers, competitors, and geographies — so the stories that don't name your tickers, but move them, reach you too.
Do I have to connect my brokerage account?
No. You type in your tickers. When broker sync arrives it will be strictly read-only via established aggregators — there are never keys to your money.
What happens when I join the waitlist?
You'll get one email when your founding spot opens, with your two-week free trial. We onboard in small cohorts so every portfolio graph gets verified before its first briefing ships.
Your portfolio deserves its own analyst.
