TLM vs Greenlight Guru
Both are real quality systems — but they’re built for different teams. Greenlight Guru is purpose-built for medical device. TLM is the flexible, complete QMS for growing manufacturers across every regulated industry — with a dedicated rep, AI built in, and a fraction of the cost. Here’s an honest side-by-side.
A fair comparison · we’ll tell you when the other guy is the better fit
Which one is right for you?
Choose Greenlight Guru if…
you’re a well-funded, medical-device-only company that wants a platform shaped entirely around established MedTech workflows — and can invest at the premium tier.
Choose TLM if…
you want a flexible, complete QMS that molds to how you already work, spans regulated industries (medical device included), comes with a dedicated rep who stands it up with you, and costs a fraction of enterprise — with Claude doing the heavy lifting.
TLM vs Greenlight Guru, line by line
The validation question most buyers forget to ask
Both TLM and Greenlight Guru give you a credible, risk-based validation story — GLG ships a validation package with each release, and that’s genuinely useful. The real question isn’t whether you can validate. It’s who controls your validated state — and how much testing each update actually costs you.
What to test — risk-based
Both follow the FDA’s Computer Software Assurance approach: test in proportion to risk, not everything. Table stakes — and TLM matches it.
How you test — Validation Katas
TLM proposes a concise, whole-workflow test for exactly what changed since your last validated version, grounded in your own configuration. You confirm it, run it on your sandbox, and sign — not a generic script to map to your use.
When updates land — you decide
The part a shared platform can’t match. On a multi-tenant cloud, updates arrive on the vendor’s schedule. On TLM you run on your own server — nothing changes until you’ve validated it and choose to apply it.
Who scopes it — Sensei Claude
Because TLM knows the exact changes to your system, it scopes the smallest relevant test set — the changes since your baseline, and nothing you didn’t touch.
Why single-tenant wins here
A multi-tenant platform serves every customer one shared application, so it can’t let one company freeze its validated version while others move on — and low-risk updates can arrive without notice. TLM gives each company its own server, so your validated state stays yours: you apply a change because you needed it and validated it — never because a release calendar pushed it to everyone at once. For a regulated team, that’s the difference between staying validated and re-validating on someone else’s schedule.
Plenty of QMS platforms are multi-tenant. A few enterprise systems are single-tenant — at enterprise prices, and they warn you off the very customization TLM is built around. Single-tenant, built to fit you, and priced for a growing team: that’s a combination we haven’t found anywhere else.
You can’t verify a vendor’s promises — but you can verify their architecture. Single-tenant is the evidence a vendor built around you, not their own margins.
TLM runs circles around one-size-fits-all competitors because our design follows one philosophy: the customer’s needs come first — not the vendor’s convenience.
What sends manufacturers from Greenlight Guru to TLM
Flexibility, not a fixed mold
TLM bends to your process instead of forcing MedTech-shaped workflows on you — a common reason teams outgrowing a rigid system switch.
Beyond medical device
Aerospace, electronics, food, contract manufacturing — TLM runs one complete QMS across regulated industries, not just MedTech.
A real person, hands-on
Your dedicated rep stands the system up with you and trains your Management Rep — not a ticket queue.
A fraction of the cost
Enterprise-grade, audit-proven results without the enterprise price — so a growing team can actually afford a real QMS.
A system, not a module bill
Greenlight sells capability à la carte — you buy modules, then buy more as you grow. TLM is one system, priced by company size and locked in: use five areas or all thirty, scale from ten users to two hundred, and the price doesn’t move. No per-module upsells, no nickel-and-diming.
AI that acts, not just advises
Claude reviews your documents against their standards, then edits them into a change order — and rolls the whole system up into a Management Review.
Complete on day one
~60 interlinked procedures ship written and ready to release — not a stack of blank templates to fill in yourself.
When Greenlight Guru is the better fit
Greenlight Guru has real medical-device depth and years of experience, and it’s locked in a mature, well-honed approach to design control. But a multi-tenant platform can only offer that approach one way — the same workflows, the same level of detail, for every customer. If that one size fits your company perfectly and cost isn’t a concern, Greenlight Guru is a genuinely strong, focused choice — and we’ll say so. TLM gives you medical-device design-control features too — with the added flexibility to shape each workflow to the level of detail your company actually needs, not the level a shared platform imposes on everyone. If you’re not sure which camp you’re in, book a demo and we’ll give you a straight answer.
