What would you say is the best way to penetrate a market?

By approaching each potentiel customer little by little.

The advantage of that approach is that it'll give us time to adjust, tweak and have a better control overall because we go at our pace.

The disadvantage here is that the competition will probably make a move to get rid of us by whatever means are necessary.

By investing a lot upfront. That is by hiring developers, salespersons, ...

The advantage of that approach is that we'll manage to get on the field of the competition in a way that it'll be too late for them to react because we'll cover all the potential customers fast.

The disadvantage is the it'll put pressure on our business. By going that direction we'll have less time to react to possible mishaps. we'll be forced to sell fast to pay for all the investments. And keep the machine rolling afterwards.

So the big questions here.

Is it still possible to take our time to get in business and stay in business?
We don't really have the choice and we must start big right away?

As always thanks for all the feedback.
