Levi Strauss and the customer who solved the problem

Levi Strauss arrived in San Francisco in 1853, during the gold rush, and did not go looking for gold. He opened a dry goods wholesale business supplying the small stores that supplied the miners: cloth, blankets, thread, clothing.

The position was unglamorous and structurally excellent. Prospecting was a lottery. Supplying prospectors was an annuity. Strauss took a small, certain margin on everything the boom consumed, whether or not any individual customer struck anything.

It also put him at a specific vantage point. A wholesaler serving hundreds of shops sees demand in aggregate, earlier and more clearly than any single retailer. He was not close to the miner. He was close to the pattern.

In 1872 Jacob Davis, a tailor in Reno who bought his cloth from Strauss, wrote to him. Davis had been putting metal rivets at the stress points of work trousers, at the pocket corners and the base of the fly, because his customers kept tearing them. The rivets worked, orders were mounting, and he could not afford the sixty eight dollar patent fee alone.

Strauss paid it and the patent was granted in 1873 in both names. Davis moved to San Francisco to run manufacturing. The riveted waist overall went into production and became, over the following century, the most widely worn garment in the world.

The obvious alternative was available. Strauss could have declined, copied the idea, and manufactured at a scale Davis could never match. Instead he bought a partner. Whatever the mix of ethics and calculation behind it, the effect was that the person who understood the innovation ran its production for years.

It is worth asking why Davis wrote to a cloth wholesaler about a patent. The answer is that Strauss had spent twenty years being the person his customers dealt with directly and fairly. The letter is a return on relationships that had no obvious commercial purpose when they were being formed.

This is the part of the story that resists imitation. There is no process for being written to. A company either has enough real contact with the people who use its products that improvements travel back up the chain, or it does not, and it finds out which only when something like this fails to arrive.

The modern version is unglamorous: the support queue, the unfiltered complaint, the customer who has bent the product into a use nobody planned. Most of it is noise. Occasionally it is a rivet.

The company did not diversify quickly. It made durable work clothing for labouring people, decade after decade, through the founder's death in 1902, through the 1906 earthquake that destroyed its factory, into a century in which the garment's meaning changed completely without the garment changing much at all.

That patience is the quiet lesson. Strauss's business was correct at the level of the need rather than the moment. People who do physical work need trousers that do not tear, and that requirement did not expire when the gold did.

Founders are usually advised to look for large trends. The counter-example here is a business built on a requirement so ordinary that it stayed true for a hundred and fifty years while everything around it changed.
