ThunderClap

ThunderClap is a B2B web design and branding agency based in India that works with scaling SaaS companies, AI startups, and venture funds. Founded by Ayush Barnwal, Harsh Kumar, and Kiran Kulkarni, the team has launched 144+ B2B websites and works with 88+ brands. The agency positions itself as a single vendor that handles positioning, branding, design, and development in a structured 10-week process—work that many competitors split across three or four agencies.

The core insight driving ThunderClap's positioning is straightforward: product-market fit doesn't always translate to messaging-market fit. A scaled startup's website often hasn't evolved with the business. ThunderClap bridges that gap by starting with a product clarity audit and strategic repositioning before touching design. Clients report 50% increase in demo requests and 60% increase in user engagement post-launch.

Services and capabilities

ThunderClap's service line sits entirely within Webflow. The team does Webflow design (wireframing, UI/UX, responsive layouts), Webflow development (custom code, CMS setup, integrations), website maintenance (rapid turnaround support), SEO (technical and content-driven), and migrations from WordPress and other platforms.

The design phase emphasizes conversion intent. Rather than treating a website as a brochure, ThunderClap frames it as a "conversion engine" that removes friction and drives users toward key CTAs. They prototype in Figma or Webflow, iterate on user journeys, and build responsive designs using Webflow's grid system. Development includes Figma-to-Webflow conversion, custom JavaScript, CMS structures for blogs and product catalogs, and integrations with HubSpot, Salesforce, and niche APIs.

Performance and scalability matter to the team. They use clean code, image compression, lazy loading, and Webflow's global CDN to ensure fast load times and "99.99% uptime." They also emphasize that the cost of fixing scalability issues on a broken website can be "up to 10X its initial development," so they optimize for scale upfront.

On the strategy side, ThunderClap has an in-house PMM team that drives positioning and messaging before design begins. This front-loaded focus on clarity is where the firm claims differentiation from generalist agencies that "outsource copy or add strategy later."

The team also includes Anisha Panicker (Art Director), Ankita Deb (Senior Accounts Manager), and Qamar Aziz (Webflow Lead). Team size is not explicitly stated, but the firm describes itself as a "specialized squad" rather than a large organization.

The agency claims "Webflow experience of 130+ websites for niche industries" and notes "10+ industry-recognized awards," though specific award names and certifications (ISO, SOC 2) are not mentioned in the source material. No partner status with Webflow, Google, or other platforms is stated.
