At Maihem, our mission is to empower every manufacturer, no matter their scale, to invent and build anything using intelligent robots. We are witnessing the start of a new industrial revolution—an era of rapid innovation and advanced manufacturing powered by AI and robotics. We aim to lead this shift by putting these tools into the hands of every manufacturer, ensuring the power to invent and build at scale isn’t a privilege of the few. But this era of abundance depends on solving a systemic labor crisis. For any economy to advance its industry and secure its supply chains, it must address the work that no longer attracts a human workforce. We are building AI to handle the dull, dirty, and dangerous.

Revealta helps businesses understand where they're being overlooked when potential customers search — and what can be done about it. We test real customer searches across Google Search and AI recommendations to see whether a business appears, which competitors are being discovered instead, and where meaningful visibility gaps exist. When we find a gap, we investigate the signals that may be contributing to it — from website relevance and local presence to authority, trust signals and AI discoverability. We then prioritize and implement improvements and re-measure visibility to understand what changed. Our approach is evidence-led: rather than starting with generic SEO recommendations, we start by testing what customers actually see. We're currently growing Revealta's sales and partner network and are looking for ambitious independent salespeople who want to help businesses uncover opportunities they're currently missing.
