Yellowchalk Design

Yellowchalk is a UI/UX design studio based in Bangalore, India, with an office in Singapore. Founded in 2017, the company has worked with 150+ clients across fintech, healthcare, edtech, retail, and enterprise sectors. The founding team—Rajiv Kakati (CEO), Pooja Dihingia (Chief of Design), and Prantik Barua (Chief of Growth)—built the studio around a philosophy of combining design research with development execution. Their portfolio includes work with EY, Intel, Changi Airport, Titan, Vidal Health, Goalwise, and AppAchhi. Yellowchalk explicitly states they do not sacrifice quality for profit, overpromise, or work for free.

Services and capabilities

Yellowchalk's service offering spans both design and development. On the design side, they handle user research, heuristic evaluation, persona development, user journey mapping, information architecture validation, wireframing, visual design, interaction design, rapid prototyping, and design systems. The company also delivers brand identity design and UX audits to identify usability gaps.

Development services include web development, mobile app development, AI and ML integration, enterprise mobility, infrastructure and cloud services, and reporting and visualization. They position themselves as full-service—architecture, build, and delivery happen in-house using agile, iterative methods.

Their engagement model follows a four-phase process: Discover (design audits, competitive analysis, user testing), Define (establish timelines and success metrics with client input), Design (research and data-driven design), and Develop (translate design into functional code).

Notable work

For Goalwise, a fintech investment platform, Yellowchalk designed an underwater-themed interface to make mutual fund investing feel less daunting to novices. They introduced a chatbot to guide new users through KYC registration and a buddy system pairing users with chartered accountants. The platform grew to over 10,000 users, and Ankur Choudhury (Goalwise co-founder) noted the design was "one of our USPs which helped us grow organically," adding he has returned with complex requirements repeatedly over a four-year relationship.

For Vidal Health, they designed an insurance-integrated mobile health app. Dr Ieshan Bali (Product Owner) credited their "user obsessive attitude and detail-oriented approach" with helping solve customer issues at the design and flow level. Pradeep Soundararajan (AppAchhi founder) highlighted their methodical process and ability to make stakeholders think deeper about their own product when designing their test automation platform. Other completed projects include a learning management system (LMS), an ecommerce site for Gumtoo, ATM screen interfaces for a major Indian bank, and a real estate investing platform (Blue Lake Fund).

How they work

Yellowchalk operates from offices in Bangalore (HSR Layout) and Singapore. The team includes 12-15 named staff: two UX designers, two UI designers, a graphic designer/illustrator, plus marketing, HR, and operations roles. They emphasize collaboration with clients, stating "great work is a result of great collaboration—and a pinch of passion and talent." No pricing information is published on the website, and engagement terms must be discussed directly.
