Who NESEN is for

NESEN serves four distinct groups, each with a different reason to be in the room.
If your next client, partner, or opportunity comes through a trusted introduction — this is for you.
Entrepreneurs Entrepreneurs

Entrepreneurs

Active business builders who grow through trusted relationships rather than cold outreach. Your classification is yours exclusively — no one in the room competes for your clients.

  • Referral exchange — warm introductions
  • Peer accountability — weekly cadence
  • Complementary network — no competitors

The weekly meeting — 90 minutes

Every Thursday at 6:30 PM. A proven format that turns attendance into referrals.
Hard stop at 90 minutes — always.
1

Open Networking

Informal, before the gavel. Welcome visitors, schedule one-to-ones for the week.

2

Chapter Updates

Referrals passed, closed business, visitor introductions, open classifications. Transparent numbers make the value visible.

3

Education Moment

Optional. One member, 3–5 minutes, on a topic relevant to the group. Any member can suggest an extended session for the community calendar.

4

Member Presentations

Each member gives a 60-second update — not a sales pitch, a briefing for referral partners. What are you focused on, what does a good referral look like today, what should members listen for. Passing is not permitted.

5

Pitch Segment

One member per meeting. 10–12 minute pitch, then every member contributes one observation and one introduction or referral. Each member pitches roughly once every 6–12 months.

6

Referrals & Testimonials

Members pass warm referrals or give public testimonials. A referral is a named person expecting your call, with context. Not a business card. Not "I'll mention you."

One-to-One Meetings

The weekly meeting is 90 minutes. That is not enough to build referral-grade trust. One-to-ones — 45–60 minute conversations between two members outside of meetings — are where the value compounds.

Target one-to-ones
per month

Attendance

Attend the majority of weekly meetings. If you cannot attend, send a substitute — someone not already a member, briefed with your presentation and any referrals you are passing. A covered absence does not count against you.

2 unrepresented absences per quarter is the limit. Exceed it and your classification is at risk.

Rules & approaches

NESEN is a professional community. These are the expectations — by group and across all members.

Terms of Use
For Entrepreneurs
Your classification is a privilege, not a guarantee. Referrals sent to you are borrowed trust from the member who made the introduction. Follow up within 48 hours. Report outcomes back to the member who referred you. The room will send you more business in direct proportion to how well you handle what it has already sent.
For Startup Founders
Come to learn, not to impress. Use the pitch segment to expose weaknesses in your thinking, not to rehearse a polished story. Ask for specific introductions rather than general encouragement. The founders who accelerate fastest treat honest feedback as the resource it is.
For Executives
Represent your genuine interests, not just your employer's. If you are here to scout innovation, say so. If you are exploring a personal venture, say so. The group works on transparency. Members who are honest about what they need get the room's full attention.
For Scientists & Researchers
Bring your real questions, not your polished abstract. NESEN is not a conference — you will not be judged on your credentials. Describe clearly what you are trying to build and what you need. The group will help you find commercial language, but you have to start the conversation.
Across all four groups
  • Deliver what you promised at the standard you described
  • Be truthful about your capabilities before taking a referral, not after
  • Follow up on every introduction — the member who made it is watching
  • Stay constructive; the group's energy is a shared resource
  • Where your profession has its own ethical code, it takes precedence

A member who burns a contact referred to them does not just lose that relationship — they damage the credibility of every member who recommended them.

What success looks like

One behavior defines the members who generate the most value: they give without keeping score. The return comes from the group over time — and it is almost always larger than what any individual transaction could have produced.

For Entrepreneurs
A steady flow of warm referrals that replaces cold outreach entirely. It comes from members who know your business well enough to spot an opportunity in a conversation you were never part of. The return is not immediate — it compounds. Members who treat NESEN as a long-term investment consistently report it becomes their most reliable source of new business.
For Startup Founders
Arriving with an idea or early traction and leaving — months later — with a validated concept, a network of operators and investors who know your name, and the momentum to keep building. The founders who move fastest show up with specific questions and leave with specific answers and introductions.
For Executives
Becoming the person in your organization who sees what is coming before everyone else — and who has the external relationships to act on it. The executives who get the most from NESEN treat each pitch segment as a scouting session and each one-to-one as a relationship worth building on its own terms.
For Scientists & Researchers
Closing the distance between what you know and what you can build — a co-founder, a first customer conversation, an investor introduction, or a clear answer to: is this worth pursuing? The scientists who move fastest show up consistently and let the room's collective experience compress years of trial and error into months of focused progress.

The room that refers you
is one visit away.
