Hartbeat Productions

Background
This is Kevin Hart 's production company.

1st Logo (January 15, 2013-)
Nickname: "Kevin's Heartbeat"

Logo: On a background, we see "HART" in white with  tiles aligned to the vertical lines of each letter. To the left of "HART" is "BEAT" in a thin, black font with "Times New Roman" overlapping the last two letters. "Times New Roman" can be seen underneath the logo as well as a silhouette of Kevin Hart with a heart place onto his chest. Throughout the logo, more tiles appear above the existing ones, mimicking audio waveforms, as well as the heart in Kevin Hart's chest expanding a little bit before returning to its original size.

Variants:
 * A still version exists.
 * On Kevin Hart: Lyft Legend, the logo zooms away from the screen.
 * It sometimes shares the screen with other logos.

Technique: The tiles and the heart expanding.

Music/Sounds: The sound of a heart beating with a crowd cheering. Sometimes, none or the opening/closing theme.

Availability: Used in tandem with the next logo. Can be seen on Real Husbands of Hollywood (except for Season 5, which uses the next logo), an episode of Celebrity Game Face, Dave, and True Story. Also seen on the special David A. Arnold: It Ain't for the Weak.

2nd Logo (July 3, 2013-)
Nicknames: "The City", "City of Hart", "Kevin's Heartbeat II"

Logo: We see a city landscape before panning over the skyscrapers. Passing by shows a ground with "HARTBEAT" comprised of mechanical pieces forming out of the ground while expanding in sync with the heart beats. The text transforms into the one from before while popping out of the ground, alongside the same tiles mimicking audio waveforms. Two cardiograms are drawn and then disappearing; one is more closer to the screen while the other is smaller and forms the byline in black. The Kevin Hart silhouette from last time pops up with the heart expanding more than it once was.

Variants:
 * Sometimes, the logo is already formed with the only animations being the text popping out of the ground and the heart beating.
 * Still and warp-speed versions exist.

Technique: Nice 3D animation, done by Wisdom Tucker.

Music/Sounds: Same as before. Sometimes, the crowd cheering is absent.

Availability: First seen on Kevin Hart: Let Me Explain and can be seen on Night School, season 5 of Real Husbands of Hollywood, Kevin Hart Presents: The Next Level, among others.

3rd Logo (April 2, 2019-)
Nicknames: "The Microphone", "Heart Explosion", "The Stand Up Comedy Logo", "Kevin's Heartbeat III"

Logo: On a black background with a spotlight, we see a microphone zoom in to the camera, and when it leaves, the camera shows a field of moving and white bars. Then, it reveals to be a heart beat which explodes into many blocks. The blocks form the logo while "Times New Roman" and the byline fade in. Also, "HART" briefly lights up, and is now in a color.

Trivia:
 * The microphone meant to represent Kevin Hart's starting out in stand-up comedy.
 * The bars are an evolution of the city landscape from the previous logo. They move rhythmically, representing a heartbeat.

Variants:
 * Sometimes, the company name and the byline are absent.
 * A short version exists.

Technique: Spectacular graphics from Devastudios. A behind-the-scenes featurette can be seen on their website.

Music/Sounds: None or the opening/closing theme.

Availability: Seen on Kevin Hart: Irresponsible, London Hughes: To Catch a D*ck, and recent stand up specials. Used in tandem with the two logos above.
