Hi Kevin! Who are you and what are you currently working on?
Hi, I’m Kevin Yun, one of the co-founders of GrowSurf. I’m 29 years old, based out of Chicago, USA.
GrowSurf is referral software for tech startups. As a founder, I wear a lot of different hats. Primarily, I handle marketing, product/design, front-end development, and everything operations. GrowSurf is a B2B SaaS business.
What's your backstory and how did you come up with the idea?
GrowSurf was born after waiting for years for someone else to build it. My co-founder Derek and I had worked on a few web projects together, and that’s when I would search for referral software we could use. But none of the solutions looked like the right fit for what we were thinking of as a plug-and-play platform. Over the years, I would revisit googling referral software (and also look on Quora, Product Hunt, etc). Nothing ever really looked ideal. That’s when Derek and I started building GrowSurf.
The original vision of GrowSurf was to build the best piece of seamless referral software that we could imagine.
With our first version of the product, we ended up strayed far away from the original vision with a lot of technical compromises. It took some time to get back to our roots and rebuild the product, but now the business is doing much better with a renewed customer focus.
How did you go from idea to product?
We built GrowSurf v1 with quick development tools like Firebase and Heroku. We were able to deploy a working version in a few short months. Because we have experience building web and mobile products, we were able to design and develop everything ourselves. Derek handled backend architecture, and I handled design and front-end.

We ran into a ton of issues. Everything from limitations of using Firebase as our main database, to just building a version 1.0 that ended up being pretty useless to users. We took challenges as they came, but during the early days, it was everything from servers crashing and trying to debug on Heroku logs, to battling unexpected costs with Firebase and rewriting code to fit the query-price paradigm.
Another challenge very specific to our product is that we are a deeply integrated platform. So we had to build web SDKs (becoming masters of query selectors, DOM manipulation, browser compatibility, anti-fraud, and much much more) and scalable APIs (eventually implemented proper tools like Redis and Kubernetes).
GrowSurf v1 was a free product. We launched everywhere we could. Product Hunt, BetaList -- the usual suspects. Like everything else in this stage, it was hard to get attention -- especially in the marketing automation space (e.g, no one likes cold emails in this space).
We got initial batches of users, but throughout the whole first year, we never got truly ideal customers. It wasn’t until we rebuilt the product and addressed our issues that we got our first 10 real customers.
