Fill Demand, Don't Create It is Nick's core rule for launching products without an audience: rather than manufacture demand from scratch, find what people are already buying and put your own spin on it. Marketplaces like Etsy and Amazon Handmade expose public data — Etsy shows the number of sales each shop has made, and keyword tools reveal demand — so you can validate before you build. The biggest mistake he sees is starting a generic sweatshirt company that competes with everyone; the fix is finding a niche people already search for and being the second or third seller of that specific thing. When you have no audience of your own, you lean on the marketplace's audience to tell you what's wanted.
Origin
Nick formed this rule from watching countless Side Hustle Show product sellers succeed by channeling existing marketplace demand and watching others fail by trying to create demand for undifferentiated products.
Core principles
- 01Filling existing demand is far easier than creating demand from scratch.
- 02Marketplaces expose public data on what is already selling.
- 03Put a unique spin on a proven seller rather than inventing a new category.
- 04Solve people's existing pains rather than convincing them to want something new.
How to run it
- 1
Go where demand already lives
Pick a marketplace that already aggregates buyers for your category, such as Etsy or Amazon Handmade.
Pro tip Etsy listings cost about 20 cents, making it cheap to test whether demand converts.
- 2
Read the public demand data
Use marketplace sales counts and keyword research tools to see what is actually selling.
Pro tip Etsy publicly shows each shop's number of sales — use it to gauge real demand.
Watch out Etsy doesn't reveal per-product sales, so infer at the shop level.
- 3
Find a proven seller to build on
Identify a niche product with demonstrated demand rather than inventing an untested category.
- 4
Add your unique spin
Throw your hat in the ring as the second or third seller of that specific thing, differentiated by your own angle.
In the wild
A friend of Yaz's wanted to start a generic sweatshirt company — an undifferentiated product competing with everyone — instead of finding a niche item people were already searching for and buying.
→ Nick notes that niching into proven demand gives a far better rate of success than a generic launch.
A seller offered print-on-demand portraits placing customers' dogs in Henry VIII-style outfits, filling a specific, proven niche demand rather than a broad category.
→ A differentiated, demand-backed product with a clear buyer.
Common mistakes
Launching an undifferentiated product
A generic sweatshirt or me-too product forces you to create demand and compete against everyone, which is the uphill route.
Is it for you?
Best for
First-time product sellers and makers without an existing audience.
Not ideal for
Genuinely novel innovations where no comparable demand yet exists to measure.
