When Do You Need a Retainer?

Building a reliable and scalable web platform is not a one-off project.

Our WordPress retainers are designed for businesses that want to offload their technical stack to proven WordPress contributors, determined to solve your problems and increase your revenue.

  • Technical WordPress Development

  • Design and Front-End

  • Speed and Stability

  • Long-Term Growth

With 11 WordPress Core contributors, 10 Software as a Service solutions and over 565 custom WordPress plugins for clients, our team has the technical background to build practically anything on top of WordPress. 3rd party API or CRM integrations, extensible plugin and theme frameworks or migration from a proprietary system - that's what we do on a regular basis.

We have authored various PHP-driven plugins for financial management, role and capabilities control for WordPress multisite, a CRM platform, and have expertise with the most popular community plugins.

While our focus is on WordPress engineering, we won't let your look and feel behind. We design clean and stylish landing pages or admin themes, and our solutions are always mobile-friendly, with usable responsive components.

We have designed dozens of custom projects and built custom WordPress themes following the WordPress theme review standards. We use Sass and Foundation, and have built custom projects with underscores and Genesis.

We follow the WordPress Coding Standards closely, which allows us to be consistent in our development efforts. By being proactive in the WordPress development community, we tackle various problems with other PHP, platform and plugin developers, and work together on solving challenging development problems.

Thus, we are capable of improving the front-end and back-end performance of your WordPress platform and ensure that the code base follows the code quality standards without falling apart due to inconsistencies and incompatible plugins.

We believe in long-term partnerships since they allow us to focus more on work instead of calling leads. Signing a long-term contract will give us enough time to get acquainted with your business model and technical infrastructure, and build the right solution having the right context.

Those decisions would be aligned with your business goals. We also use numerous tools to ensure that the end product is stable - log analyzers, uptime and server management monitors and other scanners that make our team more productive and your platform more stable.

Case Studies

Obsev is a publishing site that hosts particularly viral entertainment and cultural commentary stories.

In November 2018, they were doing significant traffic (30MM+ page views per month) and hitting a wall with scaling challenges. With these performance issues limiting their growth it was imperative that we get them through the wall and remove the scaling barrier that was capping their growth and damaging their brand. Fast forward to today and they’ve more than quadrupled the traffic levels that were hobbling the site before.

Here is how WordPress retainers proved to be the optimal website redesign solutions.

Density is a B2B company which solution tracks anonymously how people use buildings and in-door spaces based on deep learning algorithms. Our task was to build a brand new corporate site used to present and sell the company's services and products and replace the one published on their domain at that time. Their current site was static and could not be updated easily but our team succeeded to launch the new site’s primary version within three weeks. Shortly after that we pushed live Webinars and Blog features, tasks like documents (PDF), more advanced work with Marketo forms, the Customers post type, and the Support page.

Smart Meetings is a leading media company for professionals in the meetings industry.

We got in touch regarding a website migration from a custom platform built on top of Zend Framework to WordPress, rebuilding their theme to a responsive and clean layout, breaking their content down to over a dozen post types for different types of information, transferring their custom search tools to WordPress plugins and integrating several 3rd party systems. Our team broke down the migration script into multiple sequential iterations until the entire platform had been migrated.

This, together with general speed and codebase improvements, which were highly needed, were two of our top priorities.
