For small business

A personal CRM for small business owners

When you run a small business, the relationships are the business: the regular who sends you referrals, the vendor who squeezes you in, the client who’s due for a check-in. BlackBook keeps what you know about each of them on your iPhone.

Why owners need a personal CRM

Small businesses grow on repeat customers and word of mouth. That depends on remembering people: their names, what they bought, what they mentioned last time, and when you said you’d follow up. Most of that lives in your head or scattered across texts, and it slips when you’re busy.

What owners keep in BlackBook

  • Notes on regulars and clients: preferences, family names, the project they mentioned
  • Vendors, contractors and referral partners, with what you agreed and when
  • Follow-up reminders, so “I’ll check in next month” actually happens
  • Birthday reminders, for a quick personal note that customers remember
  • Pulse, which suggests who to reach out to next from your notes, history and reminders

Fast enough for a busy day

It’s on your iPhone, so you can add a note in seconds right after a conversation at the counter or on a job site. Before someone comes back in, a quick look reminds you what you talked about last time.

Private by design

There’s no account or login. Your notes stay on your iPhone and private iCloud, there are no ad SDKs, and your data is never sold. Start free with the 25 people who matter most.
