Why SoPhy

The problems no one
has solved yet.

01 — After the event

You left the event having only met five people.

In a room of 200 people you had time to speak to maybe five or six. The rest were invisible. You have no idea whether your next investor, co-founder or key hire was standing ten feet away.

SoPhy fix

After every event SoPhy gives you 24 hours to browse the full attendee list and connect with the people you never got to meet.

02 — The lost connection

You connected. Then you lost them.

They go into your WhatsApp contacts with no context. You connect on LinkedIn and three days later you're staring at a name you don't recognise. The conversation, the reason they mattered — completely gone.

SoPhy fix

Every contact saved in one place with full context attached. Searchable instantly.

03 — Scattered notes

Your notes are scattered and forgotten.

You take notes on your phone. You screenshot their LinkedIn. It all gets buried. You remember the person but lose everything that made them relevant to you.

SoPhy fix

Attach notes directly to every contact the moment you meet them. Always there, always findable.

Will be attending Y Combinator Demo Day in Jun 2026. Back in London in Aug.

04 — The missing follow-up

You meant to follow up. You just never did.

Life happens. Three weeks pass. It feels too late. And somewhere in your network is a conversation that could have changed everything — if you'd just sent that message.

SoPhy fix

Set a follow-up reminder the moment you meet someone. SoPhy nudges you so you never drop the ball.

Built by people who know this problem.

"SoPhy was built by the team behind Rare Founders — one of the UK's largest communities of founders, investors and operators with over 24,000 members. We've watched thousands of people walk out of events having lost the contacts, the context and the follow-ups that could have changed their trajectory. We didn't build SoPhy because it was a good idea. We built it because we couldn't find anything that solved it properly."

24,000+ founders, investors and operators. We know this problem better than anyone.
