Capstone Outreach

You meet someone great. You trade cards. You mean to follow up. Then the inbox wins, the card sits in a drawer, and the relationship you were about to build never happens. Capstone Outreach exists so that never happens again. Built for solopreneurs, consultants, founders, fundraisers, and advisors - anyone whose business runs on relationships but who doesn't have a sales team behind them. You do the meeting. Capstone does everything after. SCAN THE CARD, KEEP THE MOMENT Point your camera at any business card or QR code and it becomes a contact in seconds - name, email, phone, company. Capture where you met, what you talked about, and how warm the lead is while it's still fresh. Speak your notes instead of typing them. Snap a quick selfie together so you remember the face, not just the name. Save them straight to your iPhone contacts too. FOLLOW-UPS THAT SOUND LIKE YOU The AI drafts your follow-up from your actual meeting notes - who they are, where you met, what you discussed - so it reads like you wrote it, not a robot. Edit every word, then send it from your own Gmail or Outlook, signature included. Or go bigger: have the AI draft a full 2-5 email sequence, review each message, and schedule exactly when the first one lands. Nothing ever sends without your approval. SEND IT AT THE RIGHT MOMENT Schedule any email for the day and time it should arrive. Sequences cascade automatically. Replies pause the machine so you never chase someone who already answered. YOUR CARD, EVERYWHERE Share a beautiful digital business card with a QR code anyone can scan - no app needed on their end. Tap-to-share with NFC. Keep your card and a one-tap scanner right on your home screen with the widget. FROM HANDSHAKE TO CALENDAR Share your booking link and let people grab time with you - no back-and-forth. It reads your real calendar so you're never double-booked, creates the meeting with a video call link attached, and puts it on both calendars automatically. AN ASSISTANT THAT KNOWS YOUR BUSINESS Ask in plain language - or just talk. "Who did I meet this week?" "Draft a follow-up to everyone from the conference." "What needs my attention?" The assistant knows your contacts, your meetings, and your pipeline, and it does the work, not just the talking. WHY SOLOPRENEURS CHOOSE CAPSTONE - Your next client is probably someone you already met. Capstone makes sure they hear from you. - Everything sends from YOUR inbox, in YOUR voice, with YOUR signature. - You approve every message. AI drafts; you decide. - Notes marked private stay private - never shared, never used by the AI. - One app replaces the card scanner, the CRM, the scheduling tool, and the digital business card. You didn't start your business to do data entry at 11pm. Meet people. Shake hands. Let Capstone handle the rest - and watch the people you meet become the business you're building. A Capstone Outreach account is required. Connect your own Gmail or Outlook to send email from your address. Capstone Outreach Pro is an auto-renewable subscription: $24.99/month or $250/year after a 14-day free trial (Lifetime is a one-time purchase). Payment is charged to your Apple ID at confirmation; the subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in your Apple ID settings. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://www.capstoneoutreach.com/privacy
