A lab OS, authored by operators.
RainerTek builds BioSure. We are engineers and QA practitioners who kept encountering the same broken workflow across dozens of labs. We stopped asking why and started rebuilding.

The software labs use to run a USP 797 program is typically a legacy LIMS designed for full-service clinical diagnostics — or a pile of spreadsheets, Word templates, and email threads. BioSure is the third option: purpose-built for environmental monitoring, priced for independents, and finished to enterprise standard.
Four commitments that shape the product.
- / 01
Purpose-built, not configurable.
We built for USP 797 environmental monitoring first. Every field, every screen, every report reflects that scope — so your team isn't navigating features you'll never use.
- / 02
Client portal is a right, not an upsell.
Every plan includes unlimited client seats. Your pharmacy customers deserve self-service access to their own reports without your lab paying per head.
- / 03
Audit trails are invisible until they're needed.
Every mutation is logged, every decision attributed, every version preserved — visible to inspectors, unobtrusive to operators.
- / 04
Velocity serves compliance.
A one-click report is a compliant report when every data point it contains is structured, validated, and traceable. Speed and rigor are the same motion.
Short history, intentional pace.

Working with us
We do not close deals. We onboard partners.
Every lab that picks BioSure pulls our roadmap in a specific direction. Regulators update, client needs shift, the market expands. We build in public with a small, paid team, publish changelogs weekly, and ship features that serve the labs already on the platform before the ones who might be.
