Oh My DOS!
A song and music video, radio, billboards, BTS Skytrain wraps, social media and a launch event for one water tank.

- My role
- Campaign lead, team of 6
- Brand
- DOS, by Thammasorn
- The call I made
- Market the antibacterial tank to families, with one song carried across every channel
- What happened
- $8.8MDOS sales during the campaign’s 8 months
In our survey of 470 households, 71% of buyers said clean water and their family’s health mattered most when choosing a water tank. So I built the campaign for parents.

Research with 470 households
I proposed a study of 470 household decision-makers with Ruamkid Research Studio, run over Zoom. Most knew the DOS name, but still pictured stainless-steel tanks when they heard “water tank.”
- 02
Speaking to families
DOS had always sold through construction-trade sales. I chose to speak to the families who use the water, and to present the antibacterial tank as a way to keep their water clean.
- 03
Pitching for the budget
I pitched leadership and won $800K, the biggest marketing budget DOS had ever approved.
- 04
The singer, the song and the video
I contacted Beam Kawee’s management myself and negotiated the price and terms. I co-wrote the song with a songwriter and drafted the music video. Beam, a 90s pop singer turned family influencer with 2M+ followers, starred in both with his young kids.

Launching in three phases
I led a six-person team from the launch at Siam Paragon through three phases: get noticed (the song on Spotify and the radio, the music video on YouTube, social media, billboards and BTS Skytrain wraps), earn trust (retargeted safety and certification content), then catch buyers (Google display and search). Actor Charlie Trairat even joined our TikTok dance challenge.
What customers told us, and what I decided
The 71% and steel-tank findings come from our 470-household study. The influencer and music figures come from separate Thai market data.
$8.8M is total DOS sales recorded while the campaign ran, so other sales activity is included too.
