+Dual Spain/California presence supports both EU and US client time zones -Public case study count is modest compared to larger regional players
+$10K minimum engagement keeps the door open to smaller pilot projects -Precise relationship structure with parent company Anadea is not detailed beyond a shared founding team (per company website; independently unverifiable)
+Direct founder involvement in client engagements (per company website)
