PLM for small + mid-size manufacturers
Documents. BOMs. Changes.
Workflows. Done.
Thoma is a native Windows PLM that runs on your own server. Install in minutes, bring your own data, and stop fighting the cloud-only incumbents.
No credit card. 15 seats included on the trial.
Everything a small engineering team needs
The PLM tools your shop has been faking with shared drives and spreadsheets — built into one Windows-native application.
Document control
Versioned documents with check-in / check-out, audit trails, and watermarked outputs.
Bills of materials
Multi-level BOMs with where-used, effectivity, and revision tracking.
Change requests
Engineering change orders with affected documents, approvers, and full history.
Workflows
Configurable approval flows for documents, parts, and process changes.
Project management
Stage-gate templates, baselines, Gantt, budget, ROI, gate reviews — full PM subsystem, not a bolt-on.
SolidWorks + Office add-ins
Check files in and out without leaving SolidWorks, Word, Excel, or PowerPoint.
Native Windows install
One installer, portable Postgres bundled, runs on your hardware. No SaaS lock-in.
Install on your hardware. Own your data.
Thoma ships as a single native Windows installer with portable Postgres bundled. No SaaS account, no per-document upload fees, no cloud-vendor lock-in. Your CAD drawings, BOMs, and change history live on a server you control.
Air-gapped deployments are first-class. Many of our customers are CMMC-adjacent and can't put controlled-document data in someone else's cloud.
Try it before you commit
The live demo lets you click around a working Thoma instance with realistic data — no signup, no install. Tenants reset after 6 hours of inactivity.
