Our story

Built for the people
who think for a living —
& then go climb something.

Seren started as a quiet experiment on a kitchen counter — three people, one biochemist, and a conviction that functional mushrooms deserved a better delivery vehicle than a dusty capsule.

Today it's the same small team, the same lab, the same two SKUs. We have no plans to make a third.

Three founders / small lab in Portland
The long version

It started with a bad winter.

Sera, our co-founder, was writing a dissertation and climbing 5.12 on the weekends. In February of her third year, she couldn't do either. The fog was real, the legs were gone, the capsules she'd been taking every morning tasted like sawdust and did — as far as she could tell — absolutely nothing.

She called Nik, our biochemist, who is the kind of person who owns a mass spectrometer. They tested six popular brands. Four were myceliated grain — essentially oat starch with trace mushroom. Two had no measurable beta-glucans at all.

So they made their own. Fruiting bodies only. Dual extraction. Twenty-to-one concentration. Turned into gummies because the taste made the ritual easier to keep.

We ship out of the same lab. Every pouch has a batch number. Every batch has a report. That's the whole thing.

What we believe

Three rules we don't break.

01 / Fruiting body only

No mycelium on grain.

Mycelium grown on oats is cheap and legal to label "mushroom." It is also mostly oats. We use fruiting bodies — the actual mushroom — and dual-extract them for the full active profile.

02 / Receipts on every batch

Lab reports, public.

Every batch goes to an independent lab. Every report is on our site, with the batch number on your pouch. If we can't prove it, we don't say it.

03 / Small & local

Small batches.

We make small amounts, often. We'd rather run out for a week than cut corners on sourcing.

The timeline

A short, very slow history.

2022
The kitchen counter.

First dual-extraction run. Three founders, one saucepan, a lot of parchment paper.

2023
The farmer's market.

Sold the first 200 pouches. Re-stocked twice. Took the rest of the summer off.

2024
The lab.

Leased a small space. Hired our fourth human — she runs QA and we rely on her.

2026
Still two SKUs.

Batch 07 just shipped. No third mushroom is planned. Possibly ever.

Ready to try them?

Two pouches. A thirty-day money-back guarantee. The worst that can happen is you mail us a half-empty bag and we send your money back.
