Cirkul
Cirkul makes flavor-cartridge water bottles sold via Walmart, Target, Amazon, and subscription refills.
On the record
Checkpoint: Commercial results from Cirkul's Kul carbonation platform and any patent-enforcement action against Amazon cartridge dupes
The call
Cirkul sells real product through real stores with patents behind it, but its valuation is four years stale and cheap cartridge dupes are already on Amazon.
Cirkul makes small cartridges you add to water bottles to flavor them, and it is already selling in Walmart, Target, and other major chains. The company is hard to copy in the short term because it owns factories, has patents on how the cartridges work, and has already spent over $100 million building that equipment. However, cheap copies are already appearing online, and competitors like Air Up are growing without much trouble; plus PepsiCo (which makes SodaStream) could easily enter this market if it wanted to. The one thing that could change everything is whether Cirkul's patents actually stop knockoffs from being sold on Amazon, or whether they get copied anyway. If the patents work, the company stays strong for a few more years. If they do not, cheap clones could take away its advantage fast.
Why
01
AI pressure: None apparent. AI mainly shows up as TikTok and Amazon recommendation algorithms fueling Cirkul's viral DTC sales, not as a rival product eating them. Could AI do the core job? Unlikely.
02
Bigger players: PepsiCo (owns SodaStream). PepsiCo already runs a cartridge/razor-blade model through SodaStream and could push a Pepsi-branded flavor bottle into retail anytime. Could a giant copy it? Yes, easily.
03
What protects it. Utility patents on the cartridge mechanism plus national shelf space at Walmart, Target, Kroger, and Amazon that a new entrant would need years to match.
What would change this call
Cirkul wins or loses a patent infringement case against Amazon cartridge dupe sellers. Shows whether Cirkul's cartridge lock-in can legally survive cheap clones.
PepsiCo or Coca-Cola ships a competing cartridge-bottle product into national retail. Would show a deep-pocketed incumbent entering Cirkul's exact model.
TCPA class action (Wilson v. Cirkul) settles, expands, or is dismissed. Indicates whether billing practices are causing real customer attrition.

Questions people ask
- Is Cirkul profitable in 2026?
- CEO Garrett Waggoner told Inc. in July 2025 that Cirkul remains profitable, though he declined to disclose specific revenue figures. Founders claimed on a June 2026 podcast the company has generated over $1 billion in cumulative sales since its 2018 launch, an unaudited founder statement.
- What is Cirkul's current valuation?
- Cirkul was last valued at roughly $1.07 billion post-money after a $70 million Series C led by SC Holdings, closed June 13, 2022. No new priced funding round or valuation update has been publicly reported since, making the figure four years stale as of mid-2026.
- Who owns Cirkul and is it publicly traded?
- Cirkul is privately held, founded and still run by Dartmouth football teammates Garrett Waggoner (CEO) and Andy Gay (President). It is backed by investors including SC Holdings; there is no public stock, ticker, or confirmed IPO timeline as of 2026.
- Could AI replace Cirkul's business?
- Unlikely soon. Cirkul sells physical hardware (patented flavor-dial bottles) paired with proprietary cartridge consumables, backed by over $100 million in owned manufacturing and warehouse space per a July 2025 Inc. interview. AI mainly threatens peripheral layers like marketing content and customer support, not the physical product moat.
- Is Cirkul facing any lawsuits?
- Yes. A TCPA-style consumer class action, Wilson v. Cirkul Inc., was filed November 2, 2025 in the U.S. District Court for the District of Oregon and remained pending as of that filing. A separate contract dispute, Tessy Plastics Corp. v. Cirkul, filed November 2023 in N.D.N.Y., had unclear status as of early 2024.
- Who is Cirkul's biggest competitor?
- air up, a Munich-based scent-based hydration bottle maker, is frequently cited as Cirkul's closest rival, alongside Waterdrop's flavor-tablet system. PepsiCo's SodaStream is a structurally similar razor-blade refill model that could pose a bigger threat if PepsiCo enters the flavor-cartridge category directly.
