By Paul Kalra, Founder of Hospital Connection (acquired 2016), Co-Founder of Toronto based Part n Parcel, a managed shipping economics company for Canadian e-commerce merchants.
The last conversation I had before leaving my corporate career was with the head of P&G marketing for Canada.
He sat me down and asked me if I was sure I wanted to give up such a secure future. It was 2012, I was 25 and my business partner was 22. I had $12,000 USD in P&G stock and I remember trying to time the sale to squeeze every cent out I could. That was my war chest: those shares, my savings and a conviction I could not fully explain to anyone, including myself some nights.
My DMZ application came after and it did not go the way I planned. What followed taught me that building a company is rarely a straight line and some of the moments that feel like setbacks at the time end up shaping what comes next.
Rejection isn't your final verdict.
When I came across DMZ, I was fascinated by the community, energy, resources and founders making real progress every day. It was exactly what I needed to level up and I needed to get in.
But when I applied in 2012, I was rejected, which forced questions I’d been avoiding: Was I building the right thing? Was leaving my career and burning through my savings worth it? Did this business have potential? It was my first real lesson in the founder journey: the highs are high and the lows are low.
But the feedback from DMZ was useful. The business needed stronger foundations: a clearer path to scale, a more sustainable growth model and a better understanding of where the real value was. This pushed me to look beyond what we had built and think more critically about the problem we were solving, who we were solving it for and what the business could ultimately become.
We rebuilt the model, reapplied and got in. We were accepted in 2013.
How DMZ changed my trajectory.
Getting into DMZ was an opportunity, not a win and I was there to work.
I sat at the back of the space, where you could hear the Cineplex at Yonge-Dundas through the wall. Between the action scenes and late nights, I was surrounded by founders with big visions working hard to bring them to life. That was what DMZ gave me: the feeling that we were all in it together, on the good days and the bad ones.
I needed that community more than I knew when P&G—my former employer and the partner I considered a guaranteed customer—pulled out. When your sure thing says no, the founders around you can be the difference between a bad week and the end of the company.
So I leveraged the DMZ community the way it was meant to be used. When I needed a break, I walked with fellow founders. There were workshops to learn from and a bench of DMZ experts to tap, but I had to be the one to do the tapping.
The lessons and skills I learned at DMZ have stayed with me till today. One on scalable sales taught me to turn every follow-up, objection and win into a playbook I could refine and reuse. Giving up that hour for the workshop at the time felt impossible, but has paid me back for over a decade now.
The best next step isn't always the obvious one.
When the time came to graduate from DMZ, I avoided conversations because I wasn’t ready to leave. There was too much here for me to move on.
We were showing growth, but we could not afford our own office.
But then, DMZ connected us to Toronto Metropolitan University’s Biomedical Zone. It was hard to leave and harder to restart in a new space, but this move gave us access to St. Michael's Hospital.
This ultimately provided us with the medical expertise and network that could grow our community and unlock revenue. The Biomedical Zone then led us to partner with the Parent Life Network, Canada's largest parent-focused performance marketing platform, which acquired Hospital Connection in 2016.
The acquisition: sometimes the best decision is to let go.
Going into my first startup, I always pictured myself managing a team of 200. What I came to realize is that getting there needed more time, a long navigation of a very political Canadian health landscape and a bigger team with enough runway to survive it.
In Parent Life Network, we found the right fit. Our businesses complemented each other, and together we had the reach, resources and capabilities to build something bigger than either of us could alone.
Nobody tells you how hard getting acquired is. Two parties, different emotions and disagreements over contract terms. We brought in an advisor to keep us in check and stay practical. In the end we could not agree on price, so the deal became an earn-out. We crushed it and our four-year earn-out was done in just under two.
Choosing to sell is a deeply personal decision. I had to decide if I was ready to let go. At the time, I was turning 30, my entire net worth was tied up in the company and I wanted to start a family.
The second time around, I built smarter.
While running Hospital Connection, shipping was our biggest expense. I thought we were a marketing company, but our invoices said otherwise. Shipping was complicated: every carrier had different rules, costs could depend more on the size of a box than its weight and rates kept climbing. Over time, though, we had built the scale and expertise to manage those costs effectively.
In 2016, just after the acquisition, a DMZ mentor asked if we could help solve similar shipping challenges they were facing. That conversation made me realize the problem was much bigger than our own business. Other companies were struggling with the same complexity, and we had learned how shipping economics actually work. That insight became Part n Parcel, a managed shipping economics company for Canadian e-commerce merchants.
The second time around, I knew I wanted to build differently. I had a young family I wanted to be present for, so instead of building my life around the company, I built the company around my life. We stayed lean, bringing on only what we needed and focused on building a sustainable, profitable business. Today, we’re a two-founder team serving 240+ customers and we’ve been profitable from day one.
Looking back, it's easy to connect the dots.
This is my story. Not a unicorn, not a headline exit. Challenges, doubt, real crossroads and the decision to do it again.
And at every stage, I benefited from a founder who was one step ahead and willing to share what they had learned. That’s the entrepreneurial flywheel: you get support, you build something and then you turn around and help the next founder do the same. Our ecosystem only gets stronger when founders keep paying it forward.
