Nobody killed your alumni network. It just stopped.

Most alumni networks don't die. They just never had a reason to live.

I've been thinking about something Oded Barel said when I spoke with him about building SIFTECH — Jerusalem's first startup accelerator. His point: you can't build an ecosystem. You can only recognize one when it starts happening, and then try not to get in its way.

He wasn't trying to build a movement when he joined SIFTECH. He was trying to help people he trusted. The community formed because the people in it already had reasons to be in the same room — long before there was an official structure for them to belong to.

I think about that every time I see a program send the Slack invite on graduation day.

Most alumni networks follow the same arc. The invite goes out. There's a flurry of introductions. A few people share a resource or two. Then silence. Nobody killed it. There was just nothing left to hold people there once the program ended.

The programs with active alumni communities didn't invest more in community management. They designed for connection before the program ended. The alumni network wasn't something they created after — it was something that already existed. They just gave it a channel.

The difference is specific: before graduation, founders in those programs still needed each other. Not because the program required it. Because there was a real problem they were still working on together, a network they were still building, something unfinished that kept them in contact.

Here's what I'd suggest: in the last two weeks of your program, map every founder-to-founder thread you're aware of — not the introductions you facilitated, but the conversations they started on their own. If you can't name any, the alumni network you're about to create is a Slack channel. If you can, you might already have a community — and your job is to give it somewhere to go, not to build one from scratch.

A community you have to maintain is a group. A community that maintains itself is proof the program meant something.
