Bulu is a Mexico City company that sells the BT100 Advanced Purification System, a home water purifier that turns tap water into clean-tasting drinking water. The team of five reports about 100 units installed, serving roughly 1,500 daily drinkers, with 42% of growth from referrals and early promotion through YouTube brand ambassadors and Facebook marketing.

Why They Built It

Aronson, an investigative journalist, struggled to find trustworthy drinking water while living in the Himalayas and wanted a purification technology that was both effective and sustainable. He saw a large market for that in Mexico, where tap water is not drinkable and bottled water is the norm.

Why It Worked
  • •Because the product is a physical device whose taste has to be experienced, word of mouth becomes the natural growth engine, which explains why referrals drive 42% of growth.
  • •Lab testing and scientific proof directly target the distrust left over from ineffective filters of the past, which removes the biggest barrier to a first purchase.
  • •Reframing the cost as roughly $170 for a year of unlimited purified water against about $20 per week for bottled water makes the one-time purchase easy to justify.
  • •Partnering with YouTube creators who already have large audiences gives the brand trusted third-party endorsement in a market where trust is the main obstacle.
How to Replicate
  • 1.Run independent lab tests and publish the results so prospects can verify that the water is as good as or better than bottled water.
  • 2.Put the product in front of people who can taste it, through demos, installations in homes and businesses, or taste tests, since the taste is the proof point.
  • 3.Build a referral incentive so that satisfied customers bring in new buyers.
  • 4.Recruit creators with sizable audiences to feature the product on their shows, and pair that with paid social ads.
  • 5.Show the cost comparison clearly, such as the weekly bottled water spend against the one-time system price, so buyers can see the payback.
