A minimalist logo design for a tech startup, featuring an abstract geometric symbol combining the letters "PS" in a clever, memorable way. The logo uses clean lines and negative space to create a dual meaning — at first glance it's a geometric shape, on second look the letters emerge. Flat design with no gradients, using a sophisticated two-color palette of deep navy (#1a1a2e) and electric blue (#0f3460). The symbol works equally well at 16px favicon size and on a billboard. White background. The design is balanced, symmetric where appropriate, and has clear visual weight. No text, just the mark. Vector-quality edges, perfectly smooth curves. Style references: Stripe logo simplicity, Airbnb logo cleverness, Slack logo friendliness. The overall feeling should be: trustworthy, modern, innovative but not trendy.
