Red Line first · your line's next · early access

The person you most want to meet rides with you every morning.

Blip turns your MBTA commute into real, in-person professional networking. Anonymous until you both choose — and a connection only counts if a conversation actually starts. The warm opposite of LinkedIn's dead connection counts.

Joining is free, and founding members start with bonus Blips. We open one line at a time, so there are real people to meet — not a ghost town. Red Line first; your line unlocks as your neighbors join. No spam — ever (it's literally what we're against).

You're a founding member.

You'll start with bonus Blips at launch. We're seeding the Red Line first — want to skip ahead? Send Blip to one person who commutes. That's how the network gets real.

A morning on the Red Line — you see the role, never the name.

1. See roles, not names 2. Send a Blip 3. If you both mean it — you meet

Why Blip

You have a thousand connections and fewer than fifty will ever reply. The people who'd actually help you are three seats away — every single day.

The problem

Connections aren't relationships

Cold, async, no accountability — so the request gets accepted and ghosted. A number goes up; nothing happens.

The shift

Proximity beats outreach

On a train you share a destination, a few minutes, and a face. Urgency, context, accountability — the three things a DM can't fake.

The rule

It only counts if you talk

Anonymous until you both choose to reveal. No vanity counts. A connection that never becomes a conversation simply fades.

How it works

01

Board, and Blip senses your ride

No tapping. Blip quietly detects your train — and the other Blip members riding with you.

02

See who's nearby — anonymously

Roles and companies, never names. "Works at WHOOP · Product Manager," not strangers.

03

Send a Blip. Talk. Or it fades.

Wave anonymously. If you both do, a private chat opens. Reveal only when you both choose.

Is this… safe?

The honest answer, because it's the first thing everyone asks.

Anonymous first

You're a signal, not a name

Roles and companies only. Names and faces appear after you both choose to reveal — never before.

No awkwardness

A "no" is invisible

No read receipts, no "they passed." If it's not mutual, it quietly fades. You're never stuck after a decline.

You're in control

Invisible anytime

Go invisible with one tap. No exact location is ever shared — professional context only.

Why I'm building this

I'm a grad student in Boston. I sent the LinkedIn requests; they went nowhere. Meanwhile the people I most wanted to meet rode the same train every morning. So I'm building the warm, in-person layer cold outreach can't — starting on the line I ride. — Tanmay Sangam, founder · LinkedIn
