Among the nine contenders are Aledade, Datavant, Lyra Health, Medline, Maven, Spring Health, Transcarent, Virta Health, and Zelis. These companies span areas like value‑based care, mental health, women’s wellness, and payments platforms—although volatile market conditions may delay listings into 2026.
(2) Robotics startup Filics bags €13.5 M Series A to scale warehouse automation (TechStartups)
TechStartups highlights Filics, a Munich-based robotics firm, raising €13.5 million in a Series A round led by Sandwater and Amazon’s Industrial Innovation Fund.

Ever wondered what’s the secret sauce behind some of the most addictive products ever created?
While conventional wisdom preaches that more features, more options, and more freedom lead to better products, the most iconic digital experiences of our time tell a different story entirely. Now we have come to realize that the smartest product builders are doing something radically different: they’re building walls, not doors.
Consider this paradox: Twitter didn’t become a cultural phenomenon despite its 140-character limit—it became one because of it. Instagram didn’t accidentally stumble into success with square photos—it deliberately chose that constraint. BeReal didn’t randomly decide to give users a two-minute window to post. It weaponized that limitation into its core value proposition.
These are actually masterclasses in the art of strategic constraint.
"The enemy of art is the absence of limitations."
The Psychology of Creative Friction
When faced with unlimited possibilities, the human brain freezes. Psychologists call this the paradox of choice. Give someone a blank canvas and infinite tools, and they'll often create nothing. Give them three colors and a square frame, and suddenly they're Picasso.
This phenomenon runs deeper than mere decision fatigue. Studies on the effect of constraints on creativity and innovations show that individuals, teams, and organizations alike benefit from a healthy dose of constraints. Constraints force us to work within boundaries. They eliminate the noise of endless possibilities and channel our creative energy into a defined space.
When Twitter users had exactly 140 characters to work with, they didn't complain about the limitation. They invented abbreviations, compressed complex thoughts into haikus, and created entirely new forms of wit and wordplay.
The Branding Power of Limitations
Never make the mistake of viewing constraints as technical limitations to overcome. Take Instagram's original square format. In 2010, when the iPhone's camera produced rectangular photos and every other photo app followed suit, Instagram's founders made a bold choice. They forced every photo into a square, inspired by Polaroid instant cameras and medium-format photography.
That square format became Instagram's signature. Users didn't just post photos; they "Instagrammed" them. The constraint created a verb, a culture, and a completely new way of seeing the world. Every square photo became a tiny advertisement for the platform, recognizable across the internet without a single logo or watermark.

The Genius of Artificial Scarcity
BeReal took constraint philosophy to its logical extreme by introducing the element of time. Users get exactly two minutes to take and post a photo when the app sends its daily notification. No planning, no staging, no perfect lighting—just raw, unfiltered reality within a rigid timeframe.
This artificial scarcity creates something that most social media platforms desperately chase but rarely achieve: genuine engagement. When you only have two minutes to participate, every moment matters.
Constraints force product teams to make hard choices about what matters most:
Focus over bloat: When you can't add another button, you have to make the existing ones perfect
Clarity over confusion: When you can't expand options, you have to make the current choices crystal clear
Meaning over mundane: When you can't give users more time, you have to make their limited time meaningful
The Constraint Paradox in Practice
For product builders, embracing constraints means fighting against every instinct that says "more is better." It means saying no to feature requests that seem perfectly reasonable.
The key principles for strategic constraints:
Align with purpose: Choose constraints that reinforce your product's core mission
Create recognition: Make your limitations instantly recognizable and ownable
Drive behavior: Use constraints to shape how users interact with your product
Build culture: Let limitations become the foundation for community creativity
The Future of Constrained Design
When everyone else is zigging toward more features, more options, and more complexity, the real opportunity might just be to zag toward simplicity, focus, and the beautiful power of constraint.
In a world of infinite possibilities, the smartest builders are those who choose their limitations wisely and wear them as badges of honor.

Startup Idea: Interactive Mental Health Platform
Mental health support and resources are essential for many people today, but finding personalized and accessible options can be challenging. A startup idea could be to create an interactive mental health platform that offers virtual therapy sessions, self-care tools, community support, and educational resources. Users could engage with AI-powered chatbots, participate in virtual group therapy sessions, access tailored coping mechanisms, and connect with others going through similar experiences. This platform could provide a safe and confidential space for individuals to prioritize their mental well-being, regardless of their location or schedule. With the increasing demand for mental health services and the growing acceptance of virtual therapy, this type of startup has the potential to make a significant impact on society.
