Safety Evolution is a SaaS platform serving oil and gas service companies and construction contractors (500-1,000 employee range) with safety management software designed to be proactive rather than compliance-focused. The company grew from $18,000 MRR to $54,000 MRR in one year, largely through the acquisition of competitor SafetyTech (which contributed $450,000 ARR) in a non-cash deal that involved giving SafetyTech 40% equity.
