That warning is still valid and prudent. Consultancies are highly customized one-time engagements that do not easily scale. Startups prefer to have long-term relationships built on useful software.

The difference of customization vs. implementation which is where the role of the FDE shines. A consultancy builds something specific for a customer whereas a startup builds general purpose software. The FDE can then act as a force multiplier in educating the customer on how to use the product to its full potential.

This is why over time as startups scales, opex switches from eng to sales and marketing.
