Although Tycoon's stats and numbers are above average, they are no where near enough to warrant its negative ability.
Lets consider Demara as a comparison.
Stats: Install, Base Strength, Boost, Subroutines.
Demara, ~0, 1, 2:3, 2:2
Tycoon,,,,,,1, 1, 2:3, 1:2
So, in exchange for giving the corp +2 credits, you save ~1 credit.
In addition, Demara is more powerful due to additional draws being usable for their bypass ability instead of being dead draws, making it even better than Tycoon.
In conclusion, you should just get Demara instead of Tycoon.

I'd like to point out, since you didn't, that this could potentially feed into cards like Diversion of Funds, and I feel it exists for that reason (as well as being extremely efficient). It'll definitely get you into servers in a pinch.

On the topic, Demara costs 4 credits to install to Tycoon's 1 credit. As Lynx pointed, Tycoon works well with PAD Tap.

Synergy with Diversion of Funds is rare. In addition, being 1, (sometimes 2) credits more efficient is not enough to warrant its negative ability, (and is definitely not "extremely" efficient compared to Demara).

However, its synergy with PAD Tap is notable, and may make this usable.

Also, Demara has a trash ability that allows it to bypass an ice, negating its install cost, (or sometimes even exceeding it), in the eventually net value.
