Wells & Nozzles — a way to see Amazon categories

A way of seeing

Wells & Nozzles

Every Amazon category is an oil well. Every brand inside it is a nozzle, fighting to pull the oil up. Once you see it this way, you can’t unsee it.

01The picture

Under every category on Amazon sits a pool of oil — the total money buyers are willing to spend there this month. You can’t see the pool directly. What you see are the nozzles: the brands, each one a pipe sunk into the same pool, each pulling up a different amount.

The category is the well. The brand is the nozzle. The oil it pulls is GMV. That’s the whole metaphor. Everything else is detail about why some nozzles gush and others barely drip from the very same well.

THE WELL = CATEGORY DEMAND Face Wash · ~₹120 Cr / mo flowing through the category the oil pool you cannot see directly — only how much each nozzle pulls Leader ₹1.6 Cr wide pipe · deep Challenger ₹43 L Small brand ₹4 L New entrant straw not yet in the oil
One well, four nozzles. Same oil underground. The flow rate is decided entirely by the nozzle — its width, its depth, and whether it actually reaches the oil.

02What makes a nozzle gush

Two brands in the same well can pull wildly different volumes. So the nozzle has physical properties — and each one maps cleanly to a lever you already pull in the daily check.

Pump pressure = ad spend & 1-1-1 aggression Diameter = catalog breadth / indexed ASINs Placement = ranking & keyword indexing Seal = conversion, reviews, price, BB a wide pipe with a bad seal still pulls almost nothing
Anatomy of a nozzle. Four properties decide flow rate — and every one is something you can tune. Width without a seal is wasted; pressure without placement just burns money in dry rock.
The counter-intuitive bit

In our survey, nutripro pulled ₹4.5 Cr/mo from just 10 ASINs (5% coverage) — a narrow nozzle planted directly in a rich pocket. Meanwhile gaiatop ran a much wider nozzle — 68 ASINs, 34% coverage — for ₹1.2 Cr. Diameter is not destiny. Where the straw sits matters more than how wide it is.

03Two layers of oil

No well is uniform. Near the surface sits easy oil — your branded searches, repeat buyers, high-intent demand. It’s cheap to pump and mostly yours. Below it sits hard oil — the generic, contested keywords every nozzle is fighting over. Reaching it costs rising pump pressure (ACoS climbs the deeper you push).

EASY OIL — branded & high-intent demand cheap to pump · mostly already yours · low ACoS HARD OIL — generic, contested keywords every nozzle fights here · rising ACoS · semi zero-sum COST TO PUMP low high 1-1-1 aggression = concentrate the whole pump on one straw, take the easy oil first
Why focus beats spread. Spraying thin pressure across many straws never reaches the easy oil under any of them. Concentrating everything on one hero straw drains its cheap layer fast — then you fund the next from the proceeds.

04Where the metaphor breaks — and that’s the point

A real oil well only ever shrinks. Pump harder and you just empty it faster. Two things make an Amazon well behave differently — and both are where the money is.

The well refills — and can be made bigger

Category demand regenerates every month, and a great nozzle doesn’t only extract — it can drill new reserves. Brilliant advertising, a new use-case, a new price point: these grow the whole pool, not just your share of it. Sometimes a nozzle is a pump. Sometimes it’s a drill. Knowing which job you’re doing is a strategy fork.

TODAY’S POOL drill POOL AFTER DEMAND CREATION same nozzle — bigger well
A nozzle that drills. The brands worth backing don’t just split today’s pool — they enlarge it, and ride the new oil they created.

The well is a commons

There are almost no drilling rights on Amazon. Anyone can sink a new nozzle tomorrow. So every fat, under-defended well attracts nozzles until margins compress. This is the single most important correction to the metaphor for your business:

A big well is not a buy signal. A big well with weak or few nozzles is. You’re hunting for oil nobody is efficiently pumping yet.

05The map that tells you where to drill

Put two axes together — how big is the well (category GMV) and how concentrated are the nozzles (does one brand already dominate). Four worlds appear.

FRAGMENTED nozzles (no clear leader) CONCENTRATED (one brand dominates) WELL SIZE (category GMV) → NOZZLE CONCENTRATION ↑ Niche & open small well, no owner Low ceiling. Use only as a beachhead, not a destination. Gusher, no owner big well, fragmented — ATTACK Install one great nozzle and you can become the leader. where Powerlaw clients win biggest Owned & small small well, one pump Ignore. Low oil, already defended. Entrenched gusher big well, one dominant nozzle Hard. Win only with a truly different nozzle — not more pressure on the same straw.
The drill map. The top-right — a big well nobody owns — is where an upgraded nozzle turns into the category leader. That quadrant is the entire thesis behind brand-attack-triage.

And here’s the move most people miss: category GMV alone doesn’t tell you the quadrant. You also need nozzle concentration — what share the top brand already pulls. That second number is the one your brand-sales survey is quietly building, well by well.

06Real nozzles from this week’s survey

The numbers below are live readings from the brand-sales backfill — each is one nozzle’s flow rate, and each behaves exactly as the metaphor predicts.

Nozzle (brand)Flow / moWhat it shows
nutripro₹4.5 CrNarrow nozzle (10 ASINs), rich pocket — placement > diameter
Hisense₹4.0 CrHigh-AOV well (TVs) — few units, huge oil per unit
CARESMITH₹3.6 CrStrong founder-led nozzle in a growing well
Pureit / WaterScience₹3.3 / 2.8 CrSame well (water purifiers) — MNC pump vs challenger pump
Cadbury, Hisense, PureitbigMNC nozzles — deep oil, but not your attack targets
Flyloons / SILVERARROW₹19K / 70KStraws barely touching the oil — near-dry nozzles
Amazon Basics4,437 ASINs — the giant nozzle that owns dozens of wells
Read it as a portfolio of straws

A brand isn’t one nozzle — it’s a bundle of straws across many wells. The “categories driving ~80% sales” column is literally which of a brand’s straws are actually in oil. The real unit of analysis isn’t the brand. It’s the brand-in-a-category: one nozzle, one well.

07Where Powerlaw sits

You don’t own wells. You don’t own nozzles. So what is the business? Two answers — and the second is the bigger one.

The visible business

The nozzle tuner

You sell better nozzles and smarter pump-control to nozzle-owners. Paid as a slice of the extra oil you make their pipe pull. That’s exactly why the founder-report comp is 3% of incremental Amazon GMV — you earn on the new flow, not a flat rent.

The bigger business

The cartographer

Quietly, you’re mapping every well and every nozzle in the country — size, owner, concentration, flow. The survey is worth more than any single drill. Whoever owns the map decides where everyone else drills.

next drill the field from above — bright wells gush, dim wells are nearly dry. The map is the moat.
Own the survey. Every brand-sales reading you log makes the national map sharper — and the map is what turns “which brand should we chase” from a guess into a lookup.

The whole thing in five lines

1. Category = well. Brand = nozzle. GMV = oil.
2. Same well, different flow → it’s always the nozzle (width, pressure, placement, seal).
3. Two oil layers: take the cheap branded oil first, then fund the fight for the contested oil.
4. The well refills, can be enlarged, and is an open commons — so chase big wells with weak nozzles, not just big wells.
5. Powerlaw tunes nozzles for a share of new flow — but the durable prize is owning the map of every well and nozzle.
