Hi, I’m Andri.
Independent IT advice from Reykjavík for teams that want fewer traps, clearer costs, and realistic paths toward better resilience.
built fast. built right.
the gap is identified
Small businesses need independent IT judgment before they buy more tools, renew bloated contracts, or attempt risky migrations.
Kastro is founded
Incorporated in Reykjavík as a one-person independent advisory practice. The name — part castle, part revolution — is born.
the front-door offer takes shape
Kastro grows from a single beachhead review into a broader practical technology practice: infrastructure, continuity, websites, hosting, domain trust, audit readiness, and focused product work.
domain email review launches
A lightweight domain and email-authentication service gives SMBs practical SPF, DKIM, DMARC, and sender-alignment evidence without enterprise complexity.
first advisory engagements
Kastro focuses on cost reviews, security and backup reality checks, vendor questions, and small scoped fixes.
Recover.is folds into RunAtlas
After building Recover.is into a working Iceland-hosted immutable backup platform, Kastro founder Andri Pétur places the project on hold and folds it into RunAtlas, where the work can carry forward.
what comes next
Carefully selected specialist providers and future hires can expand delivery, but the public promise stays honest: advice first, scoped execution second.
what Kastro stands for.
honesty beats theatre.
Kastro is a one-person operation today. The promise is independent judgment, clear scope, and no fake enterprise facade.
cost before ideology.
Sovereignty matters, but the first question is usually simpler: what are you paying for, and what can stop draining cash?
security must be testable.
If a backup, alert, or incident promise cannot be explained and tested, it is not a control — it is a comfort blanket.
migration is earned.
No platform change should happen because it sounds pure. It should happen because the business case is clear and the rollback path exists.
confidence with a wink.
We take the work seriously without taking ourselves too seriously. Sharp, direct, and occasionally irreverent.
the person behind the walls.
Kastro is founded and operated by a hands-on infrastructure and security specialist with deep roots in Icelandic IT.
