1. ThunderClap

Best for: Startups, mid-level and enterprise brands

ThunderClap is one of the top web design and development agencies and a premium WebFlow partner. It mainly caters to high-growth startups, mid-level and enterprise brands in SaaS, fintech, venture capitalists and real estate. It offers end-to-end web design solutions, including web strategy, copywriting, UI/UX design, CRO and SEO optimization, web development, website migration and maintenance.

ThunderClap strives to strike a balance between aesthetics and functionality in their designs. They ensure the designs they create are not just pretty but convert visitors. To ensure this, they begin their design process with an extensive website audit and client interviews. Next, they create wireframes based on the audit, adhering to UI/UX and CRO best practices. High-fidelity mockups are created after finalizing designs.

Two ways in which ThunderClap establishes itself as an industry leader are through its faster turnarounds and post-launch support.

How to find the right design agency to outsource your web design needs?

1. Gauge the scope of your project

This isn't about figuring out the deliverables but about gaining clarity about the level of support you require from the agency. Is this going to be a one-off project, or do you want ongoing support? Do you already have a design team in place and need extra hands to work on your terms? Or are you looking for end-to-end support from finalizing the web strategy to designing and web development?

Having an idea of these aspects helps you find the best one that matches your needs. For example, there are agencies that only offer services as a package and not as standalone services. While these agencies are perfect for those seeking end-to-end support, they may not be the right choice for one-time projects.

2. Evaluate their expertise

One of the ways to know if the agency you picked is worth their salt is by checking their portfolio and testimonials. Their work portfolio throws light into the industries they've catered to, their work process and their style. An agency with experience working for brands similar to yours is usually a good sign as it suggests that they are competent enough to cater to your needs.

Testimonials, on the other hand, give you the confidence to choose an agency. But instead of looking for just any testimonial, look for authentic ones that convey the functional benefits an agency helped a client achieve.

3. Understand their design philosophy

The design philosophy a web design agency follows is a mirror to the kind of work they produce. For instance, for ThunderClap, the aim is to create designs that are both stunning and conversion-focused. This means that every action, be it strategy or design, the agency makes is tied to this core principle.

Similarly, there are other brands that specialize in creating bold, out-of-the-box designs. If your needs incline more toward such designs, pick agencies who aren't afraid to go against the tide.
