Creativity, Efficiency, & Advanced AI


We've got all the big ideas and creative talent of an ad agency or creative studio except we deliver working products, not expensive presentations.


We develop lean, stable code using all the best practices of any leading dev shop, except we focus on the user experience so people actually like using what we build.


We validate, design, and prototype proof-of-concepts like any "creative technology" studio, but we do it in less time and for less money.

Co-paired AI

Co-paired AI development ensures twice the efficiency at a lower cost. We prioritize your software for innovative, precise, scalable, and quality-assured applications.

Accordina to a McKinsev Report
The economic potential of generative Al: The next productivity frontier

$4.4 T boost annually

Generative Al could add a staggering $2.6 trillion to $4.4 trillion annually across various use cases. To put this in perspective, the entire GDP of the United Kingdom in 2021 was $3.1 trillion.

75% value across four domains

About 75% of the value that generative AI use cases could deliver is concentrated in four primary areas: Customer operations, marketing and sales, software engineering. and R&D.

Industry-wide distruption

Industries like banking, high tech. and life sciences stand to gain immensely. For instance. the banking sector alone could see an added value equivalent to $200 billion to $340 billion annually if generative Al use cases are fully realized.

Automate 60% Task of Knowledge Worker

Generative Al has the potential to automate work activities that currently take up 60 to 70% of employees’ time. This is a significant leap from previous estimates, which suggested that technology could automate only half of the time employees spend working.

What is generative AI?

Generative Al is a broad label that is used to describe any type of artificial intelligence that can be used to create new text, images, video, audio, code or synthetic data.

Types of Generative AI Models

Generative AI, a powerful subset of artificial intelligence, is capable of producing new data. text. images. and videos with impressive accuracy. It uses models like generative adversarial networks (GAN) and variational autoencoders (VAE) to imitate human creativity in the media it generates.

Based on their input/output, AI models can be categorized into text-based models. video models, audio models. and more.

Text-Based Models

Large language Models (LLMs): Models like ChatGPT and T5 are among the most advanced text-based generative models. They can generate contextually relevant text given a prompt or partial sentence. Other capabilities include summarization. translation. and question-answering.

Video Models

Variational Autoencoders for Video (VAE-Video): VAE-Video models such as Video Pixel Networks and MoCoGAN can learn representations of motion and generate realistic and diverse video content. Often they are used along with CNNs.

Audio Models

Audio Generative Adversarial Networks (Audio-GANS): These models vary in their capability to handle different types of audio such as speech. music. special effects. etc. Examples include GANSynth and HiFi-GAN.

3D Models

3D Generative Adversarial Networks (3D-GANs): 3D-GANs generate three- dimensional objects. complete 30 shapes etc. Some leading models are EG3D and AtlasNet.


Generative AI facilitates co-design between humans and machines. It can be applied to generate motion trajectories. control policies, or behavior models for autonomous robots.

Generative AI Use Cases

Generative AI can work effectively with smaller amounts of data or examples, making it accessible to organizations that may not have large datasets readily available. Similarly, APIs are available to streamline the integration process. These reduce the barriers to entry and allow organizations to start leveraging AI capabilities sooner.

Customer Service Chatbots

Generative AI can power quality conversational agents through better inference-making from user inputs and generating human-like responses.

Image Synthesis

Generative AI enables the creation of realistic and diverse visual content for VR applications, movies, video games, etc.

Video Editing

Scene segmentation, object removal, or color grading are a few use cases where generative AI reduces manual effort and makes post-production easier.

Voice Generation

As generative AI can generate natural-sounding human speech, it can be used to create voice assistants, audiobooks and synthetic voices for people with speech impairments

Translation and Transcription

Generative AI can automate language translation, content localization, and transcription of audio and video content.

Data Augmentation

Synthetic data can be generated to expand training sets, improve model performance, and simulate rare scenarios for testing and validation.
