Why local-first
Own your software.
Don't rent it.
For a decade, "move it to the cloud" was the safe default. Three forces have quietly flipped that — security, cost, and regulation now all point the other way. The case for owning the systems your business runs on is no longer philosophical. It's practical.
The shift
The cloud-first era is ending
Security threats are escalating
AI assistants are being turned into attack surfaces. A routine software update or a single crafted email can now pull data out of systems organisations assumed were enterprise-grade. The more you outsource, the larger your blast radius.
SaaS costs are spiralling
Subscription prices rise faster than inflation, are set by the vendor, and are payable forever. The more your operation depends on a tool you rent, the more leverage the person you rent it from has over you.
Regulation is tightening
Data-sovereignty rules increasingly put the responsibility for where your records live, and how they're handled, back on you — not on the vendor holding them. Knowing exactly where your data sits is becoming the baseline.
The evidence
Why we believe software is infrastructure
When we say software should be owned, not rented, it isn't a slogan — it's a response to what's actually happening. Below is a curated set of evidence, organised by theme, with every claim linked to its original source. Open any item to read the detail.

Breach One breach of a vendor-held system hit ~190 million people
In 2024, ransomware against UnitedHealth's Change Healthcare unit — a system its customers didn't run and couldn't control — exposed the records of roughly 190 million people, the largest healthcare breach in U.S. history. When your records live in someone else's building, their break-in becomes yours.
The Record, 2025AI risk A single email could silently exfiltrate data from Microsoft 365 Copilot
EchoLeak (CVE-2025-32711, CVSS 9.3) was the first known zero-click prompt injection weaponised for data exfiltration in a production AI system — one crafted email, no user interaction, data pulled from a cloud assistant. The more of your stack you outsource, the larger the surface someone else can turn against you.

Pricing SaaS prices are rising about 4.5× faster than inflation
Software subscription prices climbed roughly 12.2% against about 2.7% general inflation — and they only move one way. You don't set the price of what you rent, and the vendor you depend on today can raise it tomorrow, because they can.
Vertice SaaS Inflation IndexRepatriation 37signals will save $10M+ over five years by leaving the cloud
After a $3.2M/year AWS bill, David Heinemeier Hansson (creator of Ruby on Rails) moved 37signals onto its own hardware — about $700K in servers, recouped inside the first year, with projected savings now topping ten million dollars over five years. The operators who have done the maths are voting with their feet.

Momentum France is moving 2.5 million civil servants onto a platform it controls
By 2027, France plans to move 2.5 million civil servants off Microsoft Teams, Zoom, Webex and GoTo and onto its own sovereign collaboration platform, Visio. Owning your stack is no longer a fringe stance — it is the direction whole institutions are taking.
Open Source For You, 2026Compliance Regulators increasingly require you to own your audit trail
Under FDA 21 CFR Part 11, electronic records must be trustworthy, reliable and fully auditable — and the responsibility for validation, integrity and the audit trail sits with the operating company, not the cloud vendor holding the data. Sovereignty is quietly becoming the compliance baseline, not a niche concern.
21 CFR Part 11 (eCFR)Your operating system holds your business the way a safe holds your cash, your contracts, your company seal.
You wouldn't rent that safe from someone who keeps a copy of the combination, opens it whenever he likes, sells the same model to your competitors down the road — and whose strongroom was broken into last month.
You'd own it. It sits in your office. Only you hold the key.
What this means
You can own it now — not someday
For most of the SaaS era, building your own system meant armies of engineers and years of work, so renting made sense. That era is over. AI-assisted engineering lets us build you your own system — on your hardware, with your data, under your control — for a fraction of what an enterprise licence costs each year.
That's exactly what AsymmFlow is: a local-first business operating system you own outright, not a subscription you rent. It's the thesis on this page, shipped and running a real business today.
