1st1 Technologies LLP seems to be a small but technically oriented firm / startup working in the specialized domain of advanced image-matching / image-recognition software. Their strength appears to lie in innovative algorithmic solutions (e.g., DejaVuAI) that claim to outperform standard AI-based image recognition under challenging conditions. Given their SBIR contract with the U.S. Air Force, it's likely they aim (or aimed) to serve defense / government clients perhaps for surveillance, intelligence, or other mission-critical tasks that require robust image matching. Because they remain small and (as far as public data shows) relatively low-profile, they probably operate more like a boutique R&D / software-services shop rather than a mainstream commercial software vendor
