The person you need to meet is already in your network.
Let AI and human judgment weave the connections sleeping in your cards.
Instead of finding new people, the answer is already among those you've met.
The problem? You can't see it.
80% of exchanged business cards
are never looked at again
83% of people you want to meet
are just 2 hops away
Referral-based deals close
at ~4x higher rate
After 72 hours
they won't remember you
Not for storage.
Tsumugu is built to weave real relationships.
Organizing alone doesn't build relationships. Tsumugu bundles every stage into a single flow.
AI reads each card and extracts hidden value through four questions: collaboration scenarios, contribution points, network type, and character insight.
Type "construction executive" and AI finds the right bridge in your network. Trustworthy introductions via the consent protocol.
Google Calendar + Zoom auto-sync. AI thank-you emails in 3 tones. Per-contact notes. Turn discovery into real action.
Contact details are never shared without consent. Referrals only happen when the intermediary approves. Trust comes before efficiency — by design.
Three principles Tsumugu upholds. Not feature specs — the root of our design.
AI doesn't ask "what can this person give me?" — it asks "what can I offer them?" first. Finding your contribution points is Tsumugu's first job.
No A-rank or B-score. Instead, we explain in words why you should meet someone. The final judgment is always yours.
Referrals require the intermediary's approval. Privacy builds trust — we won't reverse this order. Safety before speed.
"In the age of AI, what matters most is neither the algorithm nor the data — but the human who chose to think again." — Tsumugu design principles
AI analyzes each card from four angles: ① collaboration scenarios ② contribution points ③ network type ④ character insight. Reasons, not scores.
Natural-language search ("construction executive") → AI surfaces bridge contacts → approve/decline per candidate. Partial approval supported. Protocol built on trust.
Front & back in one shot. Read multiple cards at once. Auto-tagging by industry.
Formal / Casual / Friendly. Adjusted for role and context.
Japanese cards auto-translated into KR / EN / ZH. Read international cards in your native tongue.
14-day calendar. Pick a slot, Zoom auto-generated. Two-way sync.
AI finds "the person you should meet today" from your massive card collection. Prepare three contribution points before your next dinner or trip.
"5 years of cards sat dormant. Tsumugu surfaced collaboration scenarios, and three new business lines launched in six months."
No need to build a network from scratch. Find bridge contacts in your existing relationships and grow trustworthy deals via consent-based referrals.
"I stopped cold emailing and switched to referral-first. Close rate 4x, and the quality of meetings completely changed."
Digital card + public booking page. No app required on the other side. A single QR closes the loop on sales efficiency.
"QR codes I handed out at the expo filled next week's calendar on the spot. 10x the response of paper cards."
There are other card apps. But only Tsumugu is designed to weave relationships.
