OEM sales: the design win is not the revenue

A founder I know spent eighteen months getting a German machine builder to put his sensor into their next platform. He got the yes. He got the drawing number. He printed the email and pinned it above his desk. Then he waited two more years for money.

Nobody had told him that in OEM sales, the win and the revenue are separated by the customer's own product development cycle. He had sold successfully. He had also, without meaning to, signed up for two years of near-zero cash from his biggest account.

Selling to an OEM is not selling to a user

When you sell to an end user, they buy your thing, they use your thing, and if it works they buy more. When you sell to an OEM, your thing disappears inside their thing. Their customer never sees your name. Their engineers design around your dimensions, your interface, your failure modes. Their sales team makes promises based on your specification sheet.

That changes what they are actually evaluating. They are not asking whether your product is good. They are asking whether you are a company they can bolt into their product for the next seven years without being embarrassed.

The design-in is the whole game

There is a narrow window, usually early in the OEM's development programme, when the architecture of their next product is still soft. Components get chosen in that window. Once the drawings are frozen, the tooling ordered and the certification tests run against a specific part, switching costs a fortune. That is why incumbents stay in for a decade after they stop being the best option.

So the real question in OEM sales is not "will they buy" but "when does the next platform get specified, and am I in the room before the architecture freezes". Miss the window and the honest answer is that you are waiting for the one after.

What they are checking has almost nothing to do with performance

By the time you are in serious conversations, your technical performance is assumed. The diligence goes elsewhere: can you supply at volume, what happens when the line stops at 3am, who is your second source, what is your financial position, will you exist in five years, and can you hold a price for the duration of the platform.

This is supplier qualification wearing an engineering hat. A startup with a brilliant part and no manufacturing plan loses to a mediocre part with a factory behind it. Fairly often, deliberately.

The design win trap

Design wins feel like revenue. They get announced. They go in board decks. They are, in cash terms, an option on someone else's execution.

Your revenue arrives when the OEM ships their product, at the volume they actually achieve, on their schedule. If their programme slips a year, you slip a year. If they cancel, you get nothing, and you have spent two years of engineering support on it. Counting a design win as booked business is the OEM version of counting an LOI as an order.

The portfolio rule

Because every design win is really a bet on someone else's programme, one win is not a business. The founders who survive OEM cycles run several in parallel, at different stages, in different end markets, and they assume a healthy share will die for reasons that have nothing to do with them.

The number I use with clients is simple: if a single design win going away would end the company, you do not have a strategy, you have a hostage situation.

How to get paid before the platform ships

The best OEM founders sell three things during the years of silence. Non-recurring engineering: charge for the integration work, the custom firmware, the qualification support. Prototype and pre-production volumes: priced properly, not given away. And exclusivity, when they ask for it, which should always cost either money or a minimum volume commitment.

None of this makes you profitable. All of it keeps the account from being a two-year cash desert, and it puts a number on the OEM's own seriousness. An OEM who will not pay for engineering support is telling you where you sit on their priority list.

The question to ask in meeting one

Ask when the next platform freezes. Ask what the current component is and why they are looking at alternatives. Ask who signs off on a supplier change, and whether that person has ever approved a company your size.

You will learn more in ten minutes than in a year of demos. Some of what you learn will be that you are two years early, which is useful, because it turns a chase into a calendar entry instead of a monthly disappointment.

What to do this week

Take your three biggest OEM prospects and write, for each, the platform freeze date, the named decider on supplier change, and the earliest month real volume could land. If you cannot fill in all three for any of them, that is your next conversation, not another technical deep dive.
