01About
Krellix is built by one engineer in Louisville, Kentucky. It exists because the gap between "forward it to yourself" and "call a vendor and wait two weeks" was too wide, and nothing else filled it honestly.
02The person doing the work
I'm an end-user-technologies engineer focused on Microsoft 365, Entra ID, and Intune. My day job is the unglamorous half of IT — Conditional Access, device baselines, mailbox migrations, the kinds of tickets that don't produce case studies but do keep businesses running.
Krellix started as a feature request on CCS ThreadVault, a small Windows utility I built for IT teams handling offboarding. A few attorneys bought ThreadVault, used it for litigation prep, and told me what they actually wanted was the same tool plus a real chain of custody. Krellix is what happens when I take that request seriously.
You'll talk to me when you email support. You'll talk to me when you email sales. If you want a demo, you get me on a call — no SDR, no qualification form.

03How I build
01
Per-custodian and per-gigabyte pricing makes sense if you’re selling infrastructure that scales with usage. Krellix runs on your machine. The cost to let you do one more collection is exactly zero, so the price model doesn’t pretend otherwise.
02
If a prospect has to email sales to find out what something costs, the answer is almost always “more than you want to pay.” Krellix prices are on the pricing page. The biggest enterprise deal and the smallest solo trial pay the same sticker.
03
The app is a tool for producing a specific artifact: a sealed, timestamped, hashed collection. Everything else — the UI, the installer, the onboarding — is scaffolding. If the artifact doesn’t hold up in a hearing, nothing else matters.
04
Native .eml, PDF, JSON, standard hash formats, RFC 3161 tokens. Nothing proprietary. A reviewer in 2035 should be able to verify a 2026 Krellix export without Krellix the company still existing.
05
Every error message names exactly what went wrong and what to do. Every skipped message shows up in the manifest with a reason code. A defensible tool that quietly drops items is worse than one that doesn’t exist.
06
One engineer, one phone number, one email address. When the company grows, those stop being true — but right now they’re the reason support responds the same day and the roadmap reflects what customers actually need.
04How we got here
2024
ThreadVault v1
Built a Windows utility for IT teams handling Microsoft 365 offboarding. Archive a departing employee’s mailbox to PST or EML, done. One-time license, $300 per tenant. Sold well to MSPs and small-firm IT.
2025
The legal customers show up
A handful of law-firm IT buyers bought ThreadVault and started asking for features: chain-of-custody manifests, cryptographic hashing, timestamp tokens, Bates numbering. Not because the tool was bad, but because what they really needed was a different product that shared 70% of the code.
2025 · Q4
Decision to fork
Rather than graft defensibility features onto ThreadVault and compromise its simplicity for the IT buyer, spun up Krellix as a separate product line with its own brand, pricing, and audience. ThreadVault remains supported and sold to its original buyers.
2026 · Q1
Krellix v3.0
First public release. RFC 3161 TSA integration, SHA-256/MD5 dual-hash manifests, two-mode architecture (Personal + Enterprise), admin-consent flow for Enterprise tenants. Version 3.0 because the underlying collection engine is a direct continuation of ThreadVault v2.
2026 · Q2
Krellix v3.1 — current
Refinement release. Multi-custodian collections in Enterprise mode, deduplication reports, pre-flight permission probe that catches Add-MailboxPermission gaps before a collection starts. Added OneDrive and SharePoint collection. This is the build the trial ships.
