obsidiate.

Team


A small team in Stockholm that would rather ship proof than personality. Here’s the room, a few of the faces — and receipts you can check without trusting any of us.

The Obsidiate office
Stockholm, SwedenThe desk where Tuesdays kept getting busier — markets on the screens, coffee long past its prime.

A few of us

The whole floor won’t fit on a page — these are the ones who lost the vote.

SL.

Sara L.

CEO & co-founder

Had the fifth login that broke the camel’s back.

JW.

Jonas W.

CTO & co-founder

Wrote the first matching engine on a rented server.

AF.

Amélie F.

Head of Trading

Reads order books the way other people read the news.

IS.

Ingrid S.

Head of Compliance

Keeps the slow, proper way slow and proper.

DV.

Daan V.

Matching engine lead

Counts microseconds. Holds grudges against nondeterminism.

NE.

Nora E.

Support lead

The 3am answer, usually in under four minutes.

The Obsidiate team together
Most of the floor, one Friday in May. The night shift was asleep and disputes this photo’s completeness.

The floor

Small enough that everyone knows the order book. Large enough that no single person is a point of failure.

The trading desk

Watches every book we run, in shifts that hand over at sunrise and midnight. Someone is always awake.

The engine room

Builds and tunes the matching engine. Counts microseconds for a living, holds grudges against nondeterminism.

The compliance floor

Learned custody and compliance the slow, proper way — and keeps it that way, even when it costs growth.

Support

The same answer at 3am as at 3pm, from a human who can actually fix it. Usually in minutes.

Design

One font, two colors, no mercy. If a page can't earn trust in silence, it gets rebuilt.

The watchtower

Keeps eyes on the reserve wallets and every data feed — so the proof never has to ask for your faith.

Why trust us

May 28, 2026 The Stockholm office

Twice a year we open the office: traders, builders and the merely curious, walking the same floor as the desk. This spring — a live walkthrough of the proof-of-reserves attestation, a talk on how the matching engine spends its microseconds, and an open AMA with the OTC desk that ran two hours over.

seats, all taken

talks, zero slides about synergy

2h+

of AMA overtime

We hire slowly and deliberately — engineers, desk people and the occasional skeptic.
