Get Unfiltered with Paragon Ventures is a candid interview series spotlighting the portfolio companies of Paragon Ventures I. Through these conversations, founders share their honest thoughts on what they’re building, the problems they’re solving, and the ups and downs along the way — offering a closer look at the people and ideas driving innovation across our portfolio. In this edition, we feature Lincoln Dacy, Co-Founder and CEO of Rebee Health.
1. Could you share your background with us, and what inspired you to embark on the startup journey?
I’m a mechanical engineer by training. My career started in engineering and problem-solving, building systems, optimising processes, and thinking structurally about how things work.
But Rebee began from something deeply personal.
When my mum suffered a stroke, she was in Australia while I was based in Singapore. Like many families navigating rehabilitation, we faced a common challenge: once formal therapy sessions ended, how would you ensure exercises are done correctly? How would you track progress? And how would you know if recovery is moving in the right direction?
Distance made it even harder. I couldn’t be there physically to support or monitor her rehabilitation journey.
I started thinking surely there must be a better way to bridge this gap between clinic and home, between therapist and patient, between family members separated by geography.
Rebee was born out of that question. It started as a way to monitor my mum’s rehabilitation progress remotely. Over time, it evolved into a broader mission: to make quality rehabilitation accessible, affordable, and convenient no matter where the patient or their loved ones are.
What began as a personal solution became a platform to help thousands of others facing the same challenges.
2. What was the toughest challenge or decision you’ve faced? How do I move forward when there isn’t a clear “right” answer?
The toughest decisions usually sit at the intersection of healthcare and technology. In healthcare, you cannot compromise on safety or clinical rigour. In tech, speed is everything. Balancing those two worlds is challenging.
There have been moments where we had to decide whether to scale faster or invest more time in validation, partnerships, and clinical data. When there isn’t a clear “right” answer, I go back to asking myself: will this decision help build a better product? Will it create a better experience for our users and partners? Will it create long-term credibility?
If the answer is yes, even if it slows us down temporarily, we move forward.
3. In your view, what is the “secret sauce” in building a company that stands the test of time?
At Rebee, we are clear that we are not just building an app. We are building trust with patients, therapists, and healthcare institutions. That means investing in evidence, listening deeply to users, and building a team that cares about outcomes and not just growth metrics.
4. What is one thing you do in business that might be unconventional?
We deliberately prioritise clinical credibility over aggressive marketing.
In the startup world, the pressure to grow fast can sometimes overshadow fundamentals. We’ve taken a more measured approach, working closely with hospitals, validating outcomes, and refining our product within real clinical workflows before scaling aggressively.
5. How do Rebee Health’s innovations disrupt the current rehabilitation landscape, and what makes Rebee Health stand out from other rehab programmes?
Rehabilitation today is still largely episodic and labour-intensive. Patients attend a session, go home with printed exercises, and outcomes depend heavily on their own discipline. Clinicians have very limited visibility into what actually happens between visits.
Rebee closes that gap by enabling continuous care from hospital to home.
We combine clinically prescribed programmes with wearable motion sensors, real-time feedback, and structured remote monitoring. This allows therapists to objectively track movement quality, adherence, and progression, rather than relying solely on patient self-reporting.
What differentiates Rebee is that we are purpose-built for healthcare. We are not a consumer fitness app adapted for rehab. We integrate directly into hospital workflows, including systems like Epic, ensuring rehabilitation data is accessible and actionable within existing clinical systems.
Our approach is also backed by clinical validation. Results from ATLAS, a 400-patient clinical trial funded by NHIC and managed by SingHealth Community Hospital and Jurong Community Hospital, demonstrated measurable improvements in engagement and outcomes.
Ultimately, Rebee does not replace therapists, it extends their reach.
We amplify clinical expertise with technology, enabling scalable, data-driven, and accountable rehabilitation across care settings.
That is how we modernise rehabilitation while preserving clinical integrity.
6. What do you appreciate most about Paragon Ventures?
What I appreciate most about Paragon Ventures is their long-term perspective.
They understand that healthcare innovation is not a quick flip, it requires patience, regulatory understanding, and deep ecosystem relationships. Their strategic guidance and belief in our mission have given us the confidence to build thoughtfully and ambitiously.
