WhyNot — Your Social Plans, Simplified The best moments start with one simple decision: just go. WhyNot makes it incredibly easy to create a plan or join one happening near you. How it works: Create a plan in seconds — pick a spot, set a time, and you're live. People nearby can discover your plan and join with a single tap. Or browse what's already happening around you and jump in. Solo or with friends — it works either way. What makes WhyNot great: Create a plan — Coffee, drinks, a walk, sports, a study session — whatever you're in the mood for, post it and see who's in. Join a plan — See what's happening around you right now and join with one tap. No awkward messages, no waiting. Go solo or with your crew — Heading out alone and open to meeting people? Or planning something with friends? Both work perfectly. Real-time chat — Once you're in, coordinate details with everyone who's coming. Build your community — Connect with reliable people who actually show up. Track attendance and build trust. Why people love WhyNot: No more "when works for everyone?" group chats. No more weekends spent scrolling instead of living. WhyNot turns "I wish I had plans" into "I'm on my way" — in literally one tap. Your city is full of people who want to do the same things you do. WhyNot helps you find them. Create a plan. Join a plan. Just go.

The right people, at the right moment. Sonder is built on the idea that the right connections can change someone's path. Every user contributes to the culture of the platform. By participating respectfully and responsibly, you help create an environment where people can build meaningful relationships and move forward together. Most social platforms are designed around engagement, retention, and endless content. Sonder is designed around people. Instead of maximising time spent, Sonder helps you understand yourself, present your values, skills, and qualities to the world, and make what makes you unique visible to the right people. Sonder helps you reach your goals, connect intentionally, and build relationships with context and trust. Beyond people, Sonder also matches you to opportunities - events and experiences aligned with who you are and what you are working toward, so you can find the right room to be in, not just the right person to meet. The right connection, the right event, the right opportunity - Sonder makes sure you never miss them. --- Your profile (or as we like to call it - your digital twin) Sonder gives you a single digital identity - a representation of who you are, what you know, what you are working on, and where you are going. You choose what to share: • Where you are based • Interests, skills, qulities • Professional experience and education • Projects, goals, and creative work Your profile is the foundation for everything Sonder does. The more accurate it is, the better every match, recommendation, and goal becomes. --- Tell Sonder what you need Just type it, the way you would tell a friend. • "I am building a startup and need a technical co-founder" • "I want to study for my economics exam this week" • "I just moved to a new city and want to meet ambitious people" • "I am looking for a mentor who has raised a pre-seed round" Sonder matches you based on goals, skills, interests, and context - to someone that is actually aligned with your needs. Someone who can help. Someone with experience. Someone who already did it. Someone who is working on it right now. --- Goals Set a goal in Sonder and it becomes a living, trackable plan. Give your goal a title, description, and a deadline. Add media if you want. Sonder then generates personalised steps and tasks to help you get there - built around your profile, your context, and what you are already working on. You can also • Invite others to work on a goal with you • Create a group chat directly from any goal • Track progress as you complete each step Everything is personalised. No generic advice. Just a clear path forward, shaped around you. --- Events Sonder matches you to events where you are likely to meet people worth knowing. Based on your profile, goals, and interests, Sonder surfaces events that are relevant to you - not just what is popular or nearby. You can also browse and filter events yourself. • Discover events aligned with your goals and interests • Connect with attendees before, during, and after the event Every event is an opportunity to meet the right people in the right room. --- A feed built around you You only see things that help you move forward: posts from people you are connected with, or from people Sonder thinks you should connect with, tailored opportunities, relevant articles and updates, content that matches your goals. No engagement bait. No noise. No distractions. Only what helps you move forward and grow. --- Stay connected without noise Sonder includes focused communication tools. • Messaging with your connections in one place • Group chats created directly from shared goals --- Privacy by design Your profile is visible only to Sonder and people you choose to connect with. Every connection is mutual - both sides must opt in to get connected. You stay in full control of your identity and your network. --- Sonder. Find your people, reach your goals. Never miss what matters.
