Built for both halves of your day.
FNCTN started with a frustration: the shelf was full of over-caffeinated hype and under-dosed sleep gummies. Nothing treated the day as a system. So we built one.
The shelf was selling a feeling.
Walk down the functional drinks aisle and you are asked to choose between two bad options. On one side, energy drinks selling 200mg of caffeine and a sugar load nobody asks for, engineered for a spike and quiet about the crash. On the other, sleep products carrying trace amounts of the right compounds at doses too small to do anything, wrapped in soft-focus photos and lavender.
Both are selling a feeling. Neither is selling a formula.
What was missing was the obvious thing: your day has two ends, and they need different chemistry. The morning needs a lift that does not cost you the afternoon. The evening needs help switching off without feeling groggy the next morning. Those are two different problems, so we built two different answers and made them one system.

FNCTN is built and run by Sarthak Gautam. He came to it from noon in the UAE, NITI Aayog and Bain & Company, three places where a recommendation only counted if the evidence behind it held up.
That is the habit this brand inherited. Every formulation question here was worked the same way: find what the published research actually supports, then decide what earns a place in a 5g stick. Nothing is in the formula because it markets well.

We think FNCTN should feel like engineering: precise, honest, and quietly confident. No noise. No filler. Just the compounds that work, at the doses that matter.
Restraint
We ship two products, not twenty. Every ingredient has to earn its place on the label.
Transparency
No proprietary blends, no hidden amounts. What is on the pack is what is in the stick.
Day and night
Your body runs on a daily cycle: switched on by day, winding down by night. We built one product for each half.
Four rules we do not bend.
Dose first, formula second
We start from the amount used in published research and build the stick around it. The formula is not adjusted down to hit a price or up to look impressive on a label.
Print every number
Every active ingredient appears with its exact milligram amount per stick. Some of the glycine in NIGHT comes attached to the magnesium. We print the 1.95g we add on its own and say plainly that the magnesium brings extra, rather than adding the two together for a bigger number on the label.
Two products, not twenty
A wide range is easy to launch and hard to defend. We would rather get two formulas right than dilute attention across a catalogue.
Show the papers
The Science page links the actual studies behind each active ingredient, including the reviews that call the evidence modest. You should be able to check our reasoning rather than take our word for it.
What is not in it.
Zero grams. Sweetness comes from monk fruit and Reb M, a sweetener from the stevia leaf.
Zero. The stick is the active ingredients and the flavour, nothing else.
A blend is where an underdosed ingredient goes to hide.
No compound listed at an amount too small to do anything.
No spin-off ranges, no seasonal flavours, no twelfth variant.
Not shipping yet, and saying so.
FNCTN produces in limited batches rather than holding a warehouse of stock we have to shift. That means the waitlist is real: it is how we decide how much to make, and it is the only way to get the first boxes. Members get 10% off their first order.
