Why Join Us?

Our mission to solve forgetfulness is our core driving force. What began as a personal frustration we faced, turns out to be a universal and growing problem everyone can relate to: forgetfulness in our daily life. Forgetfulness may seem like a minor inconvenience, but we believe it is a silent epidemic affecting everything from productivity, well-being, and mental clarity; and only worsens as we age. You have a chance to be an early member in a startup. Expect long hours, tough challenges, and the thrill of building something impactful from scratch. We’re here to push boundaries, and we want you to grow with us—learning, improving, and succeeding together.

Values of Memora:

Belief in Yourself – Every success story starts from somewhere. Regardless of your background or starting point, what truly matters is your unwavering belief in your potential. Embrace the mindset that your journey is about proving something to yourself, not to others. Even when you're not the most knowledgeable in the room, hold fast to the conviction that you have the potential to overcome challenges and achieve greatness. This belief drives you to push your limits and continuously learn, becoming the best version of yourself.

Humility in Success and Growth – Recognize that pride can be the greatest obstacle to progress. The philosophy here is to remain grounded both before and after success. By keeping your ego in check and being open to learning, you create room for personal and professional growth while valuing the contributions of others.

Selfless Team Mindset – Understand that no one can succeed alone. Your strength and progress are connected with those of your team. By surrounding yourself with people who elevate and inspire you, you contribute to a culture where collective success is celebrated. Our achievements are the result of shared effort, not individual success.

Mission-Driven Work Ethic – Let the impact and vision of our mission be the force that propels you forward. You don’t need external pressure to push you; instead, your internal drive and passion for what we’re building are what fuel your dedication. This mindset of continuous improvement and relentless commitment to our goals is at the heart of everything we do.
