The things
we own,
and tend.

A small but varied portfolio. Two parcels of forest in Eastern Finland, a restored homestead on Toinen Saari, seven rental apartments across three towns, and a quantitative trading book run from the same desk. We tell you about it in plain language, with no figures — those are for our auditors.

A weathered wooden rowboat pulled up on a still Finnish lake at dawn, mist on the water, pine forest on the far shore.
01Working land

The homestead.

Thirteen hectares of forest, farmland, and lake frontage on the peninsula of Paalasmaa. The buildings — three barns, a sauna, a workshop — were restored between 2020 and 2024. It is where we operate, and where the asset-management software first met a real ledger.

The Falu-red Paalasmaa farmhouse with white-framed windows, outbuildings to the side, mixed forest behind, a worn footpath through long grass.
Paalasmaa · Toinen Saari

Thirteen hectares,
three summers of work.

The hay barn took three summers to restore. The sauna was rebuilt in 2022 — same footprint, same stones, new beams. The sawmill went in the following year, and a Kubota excavator and a Valtra tractor arrived in time for the first replanting season. The forest is mixed pine, spruce, and birch; the farmland is in long fallow and managed for the long horizon.

Visitors are welcome, by appointment.

02The rest

A forestry plot,
seven apartments,
one trading book.

The rest of the operating book. Held individually under Puzzleteq's roof, run by the same small team, journaled through the same software. None of them are large; all of them are looked after.

A replanted Finnish forest: young pine and spruce saplings between weathered stumps and moss-covered logs.
Forestry · replanted Eastern Finland

The replanted plot.

Seventeen hectares of mixed forest. First harvest closed in 2022; partially destroyed by storm Paula and replanted with pine and spruce in spring 2021.

Area17 ha · acquired 2017
A pale-ochre 1980s Finnish low-rise apartment building with white balcony railings, birch trees in front, a parked bicycle.
Property · residential Ylämylly

Three apartments.

A small block of three two-bedroom apartments in a 1980s building on the south edge of Joensuu. Long-term tenants, local management, slow rent growth.

Units3 · acquired 2016
A quiet apartment interior in soft late-afternoon light, a single Windsor chair beside a window with sheer linen curtain.
Property · residential Joensuu — Marjala

One apartment, Marjala.

A single 30 m² flat in the Marjala neighbourhood of Joensuu. Held as a long-term rental; a small position kept for the municipal exposure as much as the yield.

Units1 · acquired 2018
A quiet central Oulu street in early winter, period apartment buildings on both sides, a dusting of snow on the pavement.
Property · residential Near Oulu

Three apartments, Oulu.

Three small flats near Oulu. The lightest-touch position in the book — kept for the regional exposure as much as the yield.

Units3 · acquired 2020
A single matte-black monitor on a worn wooden desk, financial charts on the screen, a coffee cup and notebook beside the keyboard.
Quantitative · in-house Helsinki · Stockholm · XETRA

The trading book.

An in-house agentic system trading on Helsinki, Stockholm, and XETRA, operated through Nordnet and Nordea. Not sold as a service. Run since 2022 against Puzzleteq's own capital only.

The forest is the easiest part of the book to operate. It does not ask for an opinion on Tuesdays. It just grows.

03How we operate

Three principles,
not strategy.

We do not have a strategy document. We have a small set of rules we follow when an opportunity comes up. The list is intentionally short and intentionally boring.

— 01

Buy things we want to operate for thirty years.

We do not hold positions we would not be happy to still own in 2056. That filter excludes most opportunities. The ones left over tend to be working buildings, land, and the kind of software we use ourselves.

— 02

Pay attention, even to the small things.

Every tenant message gets read. Every harvest plan gets signed off. The asset-management software exists to make sure none of it falls through the cracks while the founder is on the phone about something larger.

— 03

Keep an honest record.

Every harvest, every rent reconciliation, every board decision is journaled in plain language. We keep the record specifically so the next generation of the firm can read why things were done the way they were — and improve on them.

04The software

The same ledger we use,
opened up.

The asset-management software we built to run this portfolio is available, in early access, to four to six other family-office portfolios per quarter. If yours sounds like ours, the waitlist is here.
