We Help You Make Games

Small Size. Mighty Results.

Opsive is a indie company based in Raleigh, North Carolina, founded by Justin Mosiman and Sarah Watson. Justin and Sarah started to develop iOS games in 2008 and released two titles. They then switched to developing tools for the Unity Asset Store and have been doing that full time since 2013.

Opsive’s pinnacle assets on the Asset Store include Behavior Designer, the Third Person Controller, UFPS, and the newly released Ultimate Character Controller. Opsive quickly gained in popularity on the Asset Store because of the quality of their tools as well as the support provided. Opsive’s assets have a five-star average rating out of more than 2,500 ratings.

In 2023 Opsive released Omni Animation, a revolutionary AI generated animation service. Omni Animation is a deep learning network capable of producing high fidelity animations. It is designed to speed up your animation workflow and as a result, saves you time and money from creating new animations. Omni Animation is perfect for personalized hero characters, NPCs, crowds, and motion matching. More information can be found on OmniAnimation.ai.

Justin and Sarah look forward to seeing what you create using their tools – make sure you submit your project to the Showcase page!

FOUNDER

Justin Mosiman

Justin has been coding since he got his first computer at the age of 11, and he came up with the company name of Opsive shortly after that. When the iPhone was released in the summer of 2008, everything clicked and he started to create iOS apps and games. After receiving a Master’s in Computer Science, he began to work on Opsive’s first Unity asset. He then took a leap of faith and quit his full time job to start on what became Behavior Designer.

In the rare moment when Justin isn’t programming, he can be found running all over Raleigh, brainstorming even more ideas for Opsive, and traveling.

FOUNDER

Sarah Watson

Having majored in Statistics originally, Sarah is a self-taught game artist and animator. She’s always had an interest in drawing and of course video games, but didn’t truly begin her art journey until designing iOS apps for Opsive in 2008. After that she picked up 2D art and animation to create their first iOS game, and discovered her passion for 3D game art soon after. She loves creating Opsive’s demo scenes, characters, and animations as well as wearing many other hats that come with a small business (including some statistics here and there!)

When she isn’t creating art, Sarah loves to read, play Zelda, and go on adventures.
