+Nodos is a smart networking service for events. It matches attendees by real affinity (interests, goals and professional context), operates over WhatsApp without apps, and applies double opt-in before sharing contacts.

Do attendees need to install an app?

No. The whole flow runs over WhatsApp. Attendees don't install anything or create accounts — they just confirm or decline contacts.

How does the matching work?

Matching is by real affinity: interests, goals and professional context. Not by industry or job title. Before the event a short profile is collected and the algorithm cross-checks that data to detect compatibility.

What is double opt-in?

Before sharing the contact between two people, both must explicitly confirm they want to connect. No one gets another's contact without consent.

How long is the setup?

Under 48 hours. The +Nodos team handles configuration and monitoring. The organizer just shares the signup link.

How much does +Nodos cost?

Priced per event, in UF + tax, with no lock-in. Starts at 15 UF for 50 people (1 round) and goes up to 120 UF for 500 people (3 rounds). Events with more than 500 people are quoted custom. USD-equivalent pricing is shown with a 10% margin for FX volatility.

What are matching rounds?

Each round is a batch of matches sent to attendees. More rounds = more connections per person. 1, 2 or 3 rounds are offered based on event size and desired format.

What metrics does the post-event dashboard report?

Matches sent, accepted and declined; top interests; attendee profile (titles and industries); company size; acceptance rate; and up to 3 custom intake questions.

Which countries does +Nodos operate in?

+Nodos operates primarily in Chile, with pricing in UF. For events in other countries (including Mexico and the rest of Latin America), pricing is shown in approximate USD with a 10% margin. Contact hola@ampliandocirculos.cl.

About us

We're a networking community that built its own tech — not the other way around.

Who we are

+Nodos is a product of Ampliando Círculos®, a Chilean in-person networking community. We’ve spent more than three years running gatherings (over 175 of them, reaching 3,000+ people), and that taught us something simple: networking doesn’t fail for lack of willingness — it fails for lack of method.

+Nodos was born to solve that at scale: so two people with real affinity can connect before the coffee gets cold, with no apps, no luck of the draw, and no one receiving someone else’s contact without having said yes.

What we do

We operate a 1:1 affinity matchmaking system for B2B and professional events. It all happens on WhatsApp — the phone the attendee already has in hand — with double opt-in: no one receives another person’s contact unless both have explicitly approved.

The event organizer signs up, we configure within 48 hours, and afterwards we deliver a dashboard with real metrics: matches sent and accepted, top interests, group profile. Concrete data the organizer can show their leadership.

Why we care about personal data

The product processes data that matters for the attendee’s career: name, phone, company, role, professional interests. We don’t take that lightly.

Double opt-in isn’t marketing copy — it’s the only way we share a contact.
Narrow purpose: we use the data only to match within the event you signed up for, never to build parallel commercial databases.
Short retention: after the event, we anonymize. What we keep is aggregated metrics, not identifiable profiles.
Traceability: any attendee can ask us what we have on them and have it deleted. No maze-like forms.

The full policy lives at /privacy/, written to comply with Chile’s Law 19.628 (in force) and Law 21.719 (effective December 2026).
