About

Q: What does QED42 mean?

QED stands for quod erat demonstrandum, Latin for "which was to be demonstrated." It's the phrase mathematicians write at the end of a proof to mark that the argument is complete. 42 is the answer to life, the universe, and everything from Douglas Adams' The Hitchhiker's Guide to the Galaxy. The name has been on the door since we first started.

Q: Which industries do you work in?

The ones where the platform actually has to work hard. Healthcare and non-profits (Dr Reddy's, American Diabetes Association, National Kidney Foundation), higher education (Stanford GSB), finance (Kotak Securities), legal tech (Illinois Legal Aid Online), manufacturing, hospitality, FMCG, food and beverages, e-commerce, news and media, and technology. The work page has the full set of case studies.

Q: You say "performance" a lot. What do you mean by it?

We mean it literally. On greenfield builds, performance targets are written into the contract, not added at the end. Page speed, Core Web Vitals, search visibility, the things that decide whether a platform actually earns its keep. It's the first thing users feel and the first thing search engines measure, so we treat it as a deliverable, not a nice-to-have.

Q: How do you work with AI?

Practically and intentionally. Inside client work we start with real use cases, prove the value, then build further. Judgement and quality are moat. Our own conference, Oaisys, was built on the same idea: practitioner conversations should not get drowned out by marketing hype. We also lead the innovation workstream for the Drupal AI Initiative.

Q: Where are you, and who will I work with?

Headquartered in India with delivery across North America, EMEA, and APAC. Teams are hybrid and globally distributed. Senior people stay and grow here, which means the architects and leads on your project are usually the same ones a year later. ISO 27001 certified, 150+ people, NPS of 4.85.

Q: What's it like to work with QED42?

As mentioned in the How we work section, we usually start with the highest-leverage problem, solve it well, and build from there. The exception is when the client's requirements are clear and immediate — in those cases, we go straight at what's asked. Either way, most engagements turn into longer partnerships, because once the platform improves, trust builds and more becomes possible.

17+ years of craft, culture, and community building

For 17+ years, we've built digital platforms that perform better than we found them and experiences that keep users coming back. Today, that work also means building platforms that adapt as technology changes and stay ready for what comes next.

Being an AI-enabled digital experience company means preparing platforms for AI, making adoption practical by starting with real use cases, and building further when the value is clear. Accountability is part of the work from the start. Speed matters, but so do human judgment and quality.

How we work

We usually begin with the highest-leverage problem, solve it well, and build from there. That often leads to longer partnerships because once the platform improves, more becomes possible.

The team

Engineers, designers, project managers, and colleagues across people practice, marketing, and sales bring different skills, but work to the same bar: solve hard problems, build what people can rely on, deliver results, and respect time.

United by values

Deliver Excellence

Bringing Our Best to Work, striving for excellence in what we do keeps us sharp. This is the forever pursuit of excellence. This is in delivery, and this is internal too. Your partnerships will only grow stronger if we have the best interests and execute too. To go above and beyond is overused, but it is also understated. Be the extension to the partnership, be consultative. If you can successfully place yourself in their shoes and have delivered beyond the mandate, you have succeeded.

Take Charge

Getting Ahead and Leading the Way, we are here to grow together; a stick will break - a bundle will not.If you see the way, take it. Take charge of everything under your realm and don't hold back if you see something outside of it too. Be the shoulder your team / the organization/the client needs. If they can rely on you with eyes closed you have succeeded. This is superlative to ownership. If you think you need more feedback to grow, ask. If you think a solution can be delivered better, advise. If you think a process needs betterment, tell! If you have less on your plate, get more. If you have more on your plate, prioritize or delegate. We are here to grow together, a stick will break - a bundle will not.

Be Kind

Cultivating a Friendly and Generous Culture, building strong connections makes us more engaged at work. We are in the people business. People respond to kindness. Nothing trumps kindness, not even work. We are a diverse team, everyone brings in a perspective that will contribute to individual and organizational growth. Everyone brings in their best in a nurturing environment. Create and foster one. Default your nature to trust the other and the best intention.

Be Cohesive & Coherent

Working Towards a Common Goal, collaboration is the cornerstone of our teamwork. Cohesion is collaboration. This is cross-functional and within. You will deliver better together, create better relationships, and create fostering relationships. While you are creating collaboration, communication is the pillar to get there. Authentic listening is where ideas are created, egos are slashed. If you do not see a playbook to get something done, create one. If you see information dissipated, let's bring it all together. Most importantly, do not reinvent the wheel. Ask, it may already be solved.

Be Bold, Be Creative

Pushing the Envelope for Better Outcomes, curiosity and an open mind keep us going.Be conventionally unconventional. Be the jack in the box. Be the bent that nobody expected. These seeds optimize processes and also blow them out of the water. This also means reimagining experiences. Do not be afraid to view from a different lens, just because a certain thing is being done a certain way does not necessarily mean it's right. But be prudent. If you have succeeded in optimizing something that is set and/or showed a partnership that could not have been thought of, you have succeeded.

Oaisys, AI Practitioner Conference

We hosted Oaisys, an AI practitioner conference built around a simple idea: practitioner conversations should not get drowned out by AI marketing hype. Built for practitioners, by practitioners, the first edition took place on 29 and 30 November 2025.You'll find the session recordings here.

What does QED42 mean?

What are you actually known for?

QED42 is a full-service digital experience company. Not limited to one tech, and adapting fast and intentionally to how everything is changing. But if you ask around, it would be content management systems (Drupal at depth, where we're a Diamond Partner and rank in the top 10 globally on Drupal.org by contributions, #1 in India by the same measure), JavaScript engineering across React, Strapi, Next.js and decoupled architectures, user experience design (thoughtful ones), AI services, and quality engineering. Most engagements pull on more than one of these, which is one of the points of having them under one roof.
