Is there a way to make someone flat footed after the first round of combat?

Just wondering since someone brought up deadly stroke, which as 2 specific conditions to use.

Your target has to be stunned or flat footed.

Disarm + Catch Off Guard = flat-footed.

Catch Off-Guard (Combat)

Foes are surprised by your skilled use of unorthodox and improvised weapons.
Benefit: You do not suffer any penalties for using an improvised melee weapon. Unarmed opponents are flat-footed against any attacks you make with an improvised melee weapon.
Normal: You take a –4 penalty on attack rolls made with an improvised weapon.

Shatter Defenses (Combat)

Your skill with your chosen weapon leaves opponents unable to defend themselves if you strike them when their defenses are already compromised.
Prerequisites: Weapon Focus, Dazzling Display, base attack bonus +6, proficiency with weapon.
Benefit: Any shaken, frightened, or panicked opponent hit by you this round is flat-footed to your attacks until the end of your next turn. This includes any additional attacks you make this round.

The Seven-Branched Sword, which is an exotic weapon, lets you trip people to flat-foot them rather than render them prone.

Nice.

Enemies are flat-footed if they can't react to the attack against them, and if they can't see the attacker, they can't react to the attack. Concealing yourself from the target is the classic way to do it, and invisibility is the most reliable way to conceal yourself.

There are other ways, but without magic, you're basically down to a Stealth check, and once you've attacked once, you're at a -20 to Stealth for them to find you and lose their flat-footedness.

RAW Invisibility denies dex bonus to AC, however it does not make the opponent flat footed. Stealth isn't listed as denying the opponent dex bonus to AC or making them flat footed, but many DMs play it this way. So it doesn't qualify for things like sap master.

[Quath]

I think it's odd that you ask about making an opponent flat footed to use a feet that requires you to have a feat which makes your opponent flat footed as long as they are shaken, frightened, or panicked, and you've hit them since the start of your last turn.

The Scout rogue archetype renders foes "as if flatfooted" when charging (at 4th) or after moving 10ft (at 8th).

Nice.

Beware though, this doesn't make enemies with natural weapons flat-footed (since they are considered always armed)

Grease deosn't make you flat-footed.

Neither does being prone (see lots of people who think this).

And in most of these case, the terminology seems to be left over from 3.5. I think the Piazo Devs meant that after the first round, no one is 'flat footed" even tho there are a number of things that leave you open to sneak attack, etc.

Flowing Monk's Unbalancing Counter lets him render foes struck with AoOs flat-footed. Free-hand Fighter's Interference lets him make a disarm or trip maneuver check as a move action to make the target flat-footed until he takes damage or the fighter's next turn, whichever comes first. The most reliable method, though, is to make the target shaken (or frightened or panicked) and then use Shatter Defenses. A good combo is Unarmed Strikes or a Whip with the Enforcer feat which lets you cause shaken when you deal non-lethal damage.
