Give the engineer their time back.

Adducia is an early-stage company that builds safety and reliability intelligence for aerospace. It started from a simple observation. The people who keep systems safe spend too much of their day finding information. They spend too little on the analysis that matters.

Why we're building it

The hard part of safety work shouldn't be the search.

A single component's analysis can run to hundreds of pages. It is spread across FMEAs, hazard analyses, fault trees, requirements, and test evidence, often under different names in each document. Before an engineer can reason about a hazard, they must rebuild that picture by hand. We think that part should be instant, so the engineer's time goes where their expertise counts.

Rahul is a system safety and reliability engineer in aerospace. The idea for Adducia came from conversations with dozens of safety and RAMS engineers across the industry, where the same story kept repeating. The hours go to hunting down the information an analysis depends on, not to the analysis itself. He is building Adducia to close that gap.

TJ spent 32 of his 42 years in aerospace at GE Aerospace, retiring in 2024 as Principal Safety Engineer, Product Safety. For 17 years he led MIL-STD-882 safety programs for advanced military fighter engines and built the hazard tracking tool those programs ran on. He teaches the USC System Safety Certificate courses and is Vice President of the ISSS Virtual Chapter. His focus is to assist and equip the system safety professional.

What we believe

Three things we won't compromise on.

01 The engineer stays in control Adducia speeds up the work. It doesn't replace the engineer's judgment. It gives the engineer better-organized information, and the engineer makes the safety call.
02 Traceable or it doesn't count In a safety context, an answer you can't trace to a source is worse than no answer. Everything Adducia returns points back to where it came from.
03 The value compounds The more of a program Adducia connects, the more useful it gets. Your corrected, connected graph becomes an asset that grows with the work.

Next step

We're talking to early teams now.

If you run safety, reliability, or certification work and this resonates, we'd like to hear from you.
