The monthly investor email writes itself
Revenue, runway, growth, and pipeline arrive in a polished email on the first of every month. AI writes the commentary. You add a paragraph at the top and send.
Most founders treat the monthly investor update as a tax. They miss months when things are busy, then send three months at once apologising for the gap. Chartcastr takes the data assembly out of the loop. Pulses pull the numbers from your billing tool, accounting system, CRM, and product analytics on the first of every month, draft the chart and the commentary, and put a near-final email in your inbox. You add the colour and hit send.
Polished email, not a dashboard link
Investors do not log into your dashboard. They read their inbox. The Pulse arrives as a real email with charts inline and a written summary, no clicks required.
KPIs from the sources you actually use
MRR from Stripe via BigQuery, runway from your finance spreadsheet, pipeline from HubSpot, weekly active users from PostHog or your warehouse. One Pulse pulls them all.
Runway and burn that match your last raise deck
Cash on hand, monthly burn, runway months, all consistent with what you told the board last quarter. Investors notice when the methodology drifts.
A paragraph of context per chart
AI commentary explains what changed without the breathless tone. Drop in your own paragraph at the top, edit anything that reads off, send.
Different cuts for different audiences
Lead investors get the full update. Smaller checks get a summary version. Internal team gets the unredacted Pulse in Slack. One source, three formats.
Cadence that holds when you are busy
Pulses fire on a schedule whether you remember or not. Closing a deal, shipping a launch, recovering from an outage? The investor update still goes out on time.

Common questions
Can I keep the same format I already use for investor updates?
Yes. The Pulse structure is configurable. If your investors are used to a specific layout, build the Pulse to match it. The AI commentary slots into the existing format.
What about confidential metrics that go to leads but not the rest?
Run two Pulses with different metric sets. The lead investor email has the full picture; the broader update has the public-friendly cut. Same source data, different destinations.
Do investors get a logged-in dashboard or a static email?
A real email. Charts render inline as images. No login walls, no third-party portal, no expiring links. Investors archive it in their inbox like any other update.
How do I handle the months when the numbers are bad?
Same way you would handle them in a hand-built update. The AI commentary describes what happened factually; the paragraph you add at the top frames the response. The Pulse does not embellish.
