While most tech companies chase cloud apps and social networks, VisioStack is quietly building the AI nervous system for the world's railway infrastructure. With just 23 employees and $2.3M in revenue, they're tackling the unglamorous but critical problem of linear asset management—where miles of track meet machine learning.

"They're not building another SaaS dashboard—they're building the eyes and brain for railway networks."

Their social presence tells a story of focused distribution: Twitter, YouTube, and LinkedIn—no TikTok, no Instagram. This is B2B infrastructure selling to engineers, not influencers. The YouTube channel likely hosts technical demos and case studies, while LinkedIn serves as their professional network. The missing Trustpilot reviews aren't a red flag in this niche—railway procurement doesn't happen on review sites; it happens through RFPs and technical evaluations.

• 23-person team generating $2.3M revenue = ~$100k per employee (efficient for deep tech)
• 62% direct traffic indicates strong brand recall in a niche market
• Railway AI keyword volume (1,320/month) suggests growing market demand
• Bootstrapped or profitable model (no funding data) = sustainable growth
