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.
We are reviewing on a rolling basis. Successful candidates will receive an email invitation to online interviews. We’re excited to hear your story.
Have you ever felt the need to see the direct impact of what you do? Then consider this:
Currently, there are 70+ million Small and Medium Enterprises in India. And they need all the help to succeed against the continuous onslaught of much larger businesses.
Imagine a jewellery shop owner in Ghatkopar Mumbai. He may be procuring his goods that are to be sold in the shop from a fixed set of vendors - some his relatives, some that people have recommended and some that came and pitched to him. He may not have ever seen the kind of designs and products that a supplier from Mysore can offer. Or the credit terms that another supplier from Surat can offer. Putting him on a platform where he can easily browse products and build new business relationships is a life-changing proposition for him.
We believe that technology should be accessible and usable for these SMEs so that they can grow and simplify their business, and compete in a fair field.
If making the lives of businesses in India and the world simpler excites you, then this is the
perfect opportunity! You will be solving challenging problems, defining your own charter and be the master of your own growth. The best way to predict your future is to create it.
We have more than 170k businesses on our platform already with great engagement numbers.
We are backed by the top founders and VCs in the country(Titan Capital, FirstCheque).
We are set to grow even faster in the future.
Join us if you want to be a part of a fast-paced team.
