What we solved
No anxiety.
No crash.
Caffeine on its own floods your system, spikes your heart rate, and leaves you restless, then drained. The initial rush, the scattered focus, the energy dip that follows.
We fixed it in the chemistry. CRUX pairs strong coffee with 200mg of L-Theanine, the calming amino acid from green tea. It takes the edge off caffeine without taking away the energy. The spike becomes a steady curve, and the curve holds for hours.
You stay dialed in, calm, sharp, in control, then come down soft.

The calm ingredient
Caffeine brings the energy.
L-Theanine keeps it calm.
L-Theanine is an amino acid found in green tea. On its own, it relaxes you without making you drowsy. Paired with caffeine, it does something better: it smooths the surge, so you get the lift without the shaky hands, the racing heart or the crash.
Every CRUX sachet carries a full 200mg, the dose used in focus research, alongside 135mg of natural caffeine. That pairing is the whole trick. It's why one cup feels like clean, quiet energy for hours instead of a jolt that quits on you.

Nothing synthetic
Coffee. Tea.
A pinch of salt.
That’s basically CRUX: strong coffee for the lift, L-Theanine from green tea to smooth it out, and a little pink salt to add a touch of sodium. No mystery blend.
It starts in Coorg
It starts beneath the shade trees of Coorg. Arabica and Robusta cherries ripen slowly in the cool hills, then we blend and freeze-dry the coffee so its strength and aroma make it all the way into your cup.
The calm starts with tea
The story continues in rows of green tea, where tender leaves are picked while they are still fresh. They are the natural home of L-Theanine. We add 200mg to every sachet so the coffee still lifts you, but feels calmer and easier to stay with.

Energy, Calmness & Hydration
Freeze-dried coffee
We start with a bold Arabica and Robusta blend, freeze-dried to hold onto its aroma and strength. That gives you rich coffee flavour and 135mg of natural caffeine to get moving.
200mg L-Theanine
Then comes L-Theanine from green tea. It takes the rough edge off caffeine, so the lift feels calmer, clearer and easier to stay with.
Himalayan pink salt
Last comes 100mg of pink salt. It adds a small amount of sodium to support hydration on training days, while travelling and through long afternoons.

Why we made CRUX
Regular coffee was never the problem. The anxious, scattered energy was.
We're athletes and founders, and we overthink just about everything. We loved the lift coffee gave us. We just wanted a cup we could rely on before training, through long work blocks, and everywhere in between.
So we stopped trying to make coffee stronger and started trying to make the energy feel better.
We tested cup after cup, adjusting the balance each time, until the energy finally felt right: enough lift to get moving, with a calmer feel that stayed out of the way.
That became CRUX, coffee that helps you feel awake, clear and ready for what comes next.
Everything You Wanted To Ask
What is CRUX?
CRUX is strong black instant coffee made for calm, steady energy. Every sachet combines 135mg of natural caffeine with 200mg of L-Theanine and 100mg of Himalayan pink salt, so you get the lift of coffee with a smoother feel and a little sodium for hydration support.
Why add pink salt?
We add 100mg of Himalayan pink salt because it provides a small amount of sodium, an electrolyte involved in fluid balance. It supports the hydration side of the formula without making the coffee taste salty.
Why CRUX over regular coffee?
Regular coffee gives you caffeine on its own, while CRUX pairs that caffeine with 200mg of L-Theanine to soften the rough edge. You still feel awake and focused, but the energy is designed to feel calmer and steadier.
How do I make it?
Empty one sachet into 250 to 300 ml of hot or cold water, or milk if you prefer it creamy, then stir until dissolved. You do not need a machine or filter.
When does my pre-order ship?
Your pre-order will ship as soon as the launch batch is ready, and delivery is free across India. We will email your tracking link as soon as the order leaves our facility.
Do you offer Cash on Delivery?
We currently accept prepaid orders only, and you can pay securely by UPI, card or netbanking through Razorpay. Keeping the launch prepaid helps us offer the ₹799 pre-sale price with free delivery.
Can I return it?

Is it safe for daily use?
Each sachet contains 135mg of caffeine, so think of it as a strong cup of coffee and keep your overall daily caffeine intake in mind. If you are sensitive to caffeine, pregnant, nursing, under 18 or managing a medical condition, speak with a healthcare professional before using it.
