Screen-Sharing Privacy for Executives and Founders

7 min read

Sharing a board deck, a financial model or an investor update on a call risks exposing the numbers next to the one you meant to show - runway, the cap table, employee comp and unreleased strategy. Here's how to present one slide or one tab without leaking the rest.

When you share a board deck, a model or an investor update, you have to protect the numbers sitting right next to the one you're presenting - revenue and runway, the cap table and ownership splits, employee comp and headcount plans, live M&A or legal matters, and strategy you haven't announced. The safeguard is to blur the rows, cells and slides you're not presenting before you share, so scrolling a spreadsheet or advancing a deck never exposes something a candidate, a partner or one investor should never see. At the exec level a single leaked figure - a comp number, a runway date, an ownership percentage - can reset a negotiation or a relationship.

What's at stake when a founder shares a screen

  • Revenue and runway - MRR, burn and the months-of-cash line in your model, sensitive with employees, recruits and most investors.
  • Cap table and ownership - who owns what percentage, option pools and preferences, in Carta, Pulley or a spreadsheet appendix.
  • Employee comp and headcount plans - salaries, equity grants and a hiring plan that names roles you haven't opened or people you might let go.
  • M&A and legal - an acquisition conversation, a term sheet, or litigation that isn't public.
  • Unreleased strategy and roadmap - the pivot, pricing change or launch that hasn't been announced internally or externally.
  • Investor names and terms - a cap-table or update tab that reveals who's in, at what valuation, on what terms.

The riskiest moment: one slide out of a board deck

The everyday scenario is showing one thing from a document built for a different audience. You want to walk a candidate through the go-to-market slide, or show a partner a single chart from the model - but the board deck also has a comp slide and a cap-table appendix a few pages on, and the model has a runway line and a headcount tab one scroll away. Advancing a slide too far, scrolling to the wrong row, or a notification about the live acquisition talk is all it takes to expose a number that changes the conversation. Blurring lets you present the one slide or chart you mean to and keep the rest of the file frosted.

How to share a deck or model without oversharing

  1. 1

    Share one tab and silence alerts

    Present from the browser - a web deck, an online spreadsheet or a dashboard - and share that single tab, not your whole screen. Turn on Do Not Disturb so Slack and email notifications about deals, comp or hiring don't surface.

  2. 2

    Blur the sensitive rows and columns of the model

    With BlurFirst, drag a box blur over the runway line, the comp table, and any headcount or salary rows before you scroll near them. The blur stays anchored to that region as you scroll, and because it's painted into the page as real pixels, Zoom, Meet, Teams, Loom and OBS all capture it.

  3. 3

    Element-blur cap-table and comp cells

    In Carta, Pulley or a cap-table sheet, click to blur individual ownership percentages, share counts and dollar figures while leaving the structure visible. In a deck, blur the comp slide or an unreleased-strategy callout. Click again to reveal one figure if you choose to disclose it.

  4. 4

    Keep panic blur ready

    If you advance to the wrong slide or a notification about M&A appears, press Ctrl/⌘ ⇧ H to blur the whole page instantly, fix what's on screen, then reveal only what you meant to show.

  5. 5

    Save a profile for recurring dashboards

    For the metrics dashboard or model you present on every board call, save a per-site profile (Pro) so the same blurs re-apply automatically and survive the app's re-renders.

Honest limits

  • BlurFirst blurs content inside a browser tab. A model open in desktop Excel or a deck in desktop PowerPoint or Keynote is a native app it can't reach - so present from a web spreadsheet or web deck when you need blurring (a desktop app is in development).
  • The one-click Scan detects patterns - emails, phone numbers, card numbers, SSNs and API keys - locally. It does not recognize free-text names or dollar figures as sensitive, so blur comp, runway and cap-table numbers with box or element blur yourself.
  • Blurring controls what's visible during a live share; it doesn't replace access controls on the underlying files, or the judgment to keep the most sensitive material out of a shared document entirely.

Frequently asked questions

How do executives and founders protect sensitive data when screen sharing?

Present from a single browser tab, turn on Do Not Disturb, and blur the numbers you're not presenting - runway, comp, headcount, the cap table and unreleased strategy - before you scroll near them. Because the blur is painted into the page, Zoom, Meet, Teams and any recorder capture it, so advancing a slide or scrolling a model can't expose a figure that changes the conversation.

Can I show one slide of a board deck without revealing the comp slide or cap table?

Yes, if you present the deck from the browser (Google Slides or web PowerPoint) and share that tab. Blur the comp slide and cap-table appendix, or box-blur specific figures, so advancing or scrolling never exposes them. A deck in desktop PowerPoint or Keynote is a native app BlurFirst can't reach.

Does BlurFirst upload my financial model or cap table?

No. Everything you blur stays in your browser and is never uploaded or screenshotted. Per-site profiles store which element you blurred - a CSS selector - never the numbers inside it. The only network request BlurFirst makes is a license check.

Can I blur a cap-table tool like Carta or Pulley?

Yes. Both are web apps, so you can element-blur individual ownership percentages, share counts and dollar figures while keeping the overall structure visible, and reveal one line on request by clicking it again.

What if an investor or board member asks to see a number I've blurred?

Click the element to reveal it, then click again to hide it. Element blur is a toggle, so you can disclose one figure you intend to share without unblurring comp, runway or the rest of the cap table.

Blur it before you share it.

Hide any field, region or message on a page before your next call. Nothing you blur leaves your browser.
