Remember
everyone
you meet.

The cost of forgetting

Follow-up dies when the context does.

A business card can tell you who they are. It rarely tells you why the next message matters.

Memory decayClear
At the booth

The context is still warm.

You remember the product, the city, and the intro they asked for.

The note in your head

92%

Lagos launch. Asked for Wanjiru intro. Follow up Friday.

Kumbuka saves this before it fades.

How Kumbuka works

Capture, recall, follow through.

01

Scan.

Scan any business card. Kumbuka extracts the fields, keeps the card image attached, and lets you review before saving.

02

Show up ready.

Before a meeting, the brief pulls the card, place, notes, and last promise into one screen.

9 AM · in 18 min
Coffee with Lerato
03

Follow up on time.

Keep the next action attached to the person, so the follow-up does not disappear into a separate task list.

Draft · To Lerato
Great meeting you yesterday
“Hi Lerato — really enjoyed our chat about distribution. As promised, here's the Q3 deck”

The Meeting Brief

Before you walk in, the brief is ready.

When a calendar event matches names, emails, or companies in your library, Kumbuka turns saved cards into a short brief for the room.

Where we met

Every card lands somewhere. Your map keeps the place.

Kumbuka can save optional scan location or card address with the contact. Later, the map shows where a relationship started, not just where a company is based.

Location is optional and permission based.
Add a place manually for cards you scan later.

Open memory

Relationship memory

Remember the person, not just the card.

Kumbuka keeps the card image, editable fields, place, note, promise, and follow-up together, so a name comes back with the context that made it matter.

Keep the source card.
Add place, note, and promise.
Bring it back before the next meeting.

You're early — and that's the point.

We're still close to the people using Kumbuka. Early members shape the scanner, brief, map, and follow-up workflow before the product gets loud.
