Detailed comparison
A fair, category-by-category breakdown of how Clarvia Dev and Thoughtworks compare.
Clarvia Dev
AI product development. We take a product idea from concept to deployed software. Our team is small, senior, and moves fast. No discovery phases that run for months — we ship working software early and iterate.
Thoughtworks
Enterprise technology consulting with AI as a growing practice area. Thoughtworks brings deep engineering culture, proven methodologies (3-3-3 method), and their AI/works platform. Engagements typically start with discovery, followed by structured delivery phases.
Clarvia for speed and focus on a single AI product. Thoughtworks for large-scale enterprise transformation where AI is part of a broader technology strategy.
Clarvia Dev
Working prototype in 2-4 weeks. We start building from day one. Research and architecture happen alongside early development, not as separate gated phases.
Thoughtworks
Thoughtworks promises "enterprise-grade AI in 8 weeks" and uses a 3-3-3 method (3 weeks assess, 3 weeks pilot, 3 weeks scale). In practice, enterprise engagements often include pre-engagement discovery and procurement cycles that extend the total timeline to 3-6 months for initial delivery.
Clarvia if speed to first working software matters most. Thoughtworks if you need enterprise governance and are willing to invest more time upfront for structured delivery.
Clarvia Dev
Project budgets typically start in the tens of thousands. We work with startups, SMEs, and mid-market companies alongside larger firms. No minimum engagement size that puts us out of reach for smaller organisations.
Thoughtworks
As a publicly traded global consultancy, Thoughtworks serves Fortune 500 companies and large enterprises. Their engagement sizes reflect that scale — they are structured for large, multi-team programmes rather than focused product builds.
Clarvia if you need a right-sized engagement for a focused AI product. Thoughtworks if you have enterprise budgets and need a consultancy that can field large, distributed teams.
Clarvia Dev
AI is our entire business. Every team member works on AI products daily. We stay current with the latest models, techniques, and tooling because it is all we do.
Thoughtworks
AI is an important and growing practice within a broad technology consultancy. Thoughtworks has genuine AI talent, but it sits alongside practices in cloud, data engineering, DevOps, security, and enterprise architecture. AI expertise may vary by team and region.
Clarvia for concentrated AI expertise on every engagement. Thoughtworks if you need AI work combined with broader enterprise technology consulting.
Clarvia Dev
Direct and informal. You talk to the people building your product. Decisions happen in Slack, not steering committees. We challenge assumptions because we care about the product working, not about billable hours.
Thoughtworks
Thoughtworks has a strong engineering culture and genuine commitment to software craft. They are one of the better consultancies in this regard. However, the enterprise operating model brings layers — account managers, delivery leads, practice heads — that sit between you and the engineers writing code.
Clarvia if you want zero organisational layers between you and the builders. Thoughtworks if you value structured governance and the backing of a publicly traded consultancy.

Common questions
Thoughtworks is a respected name in software. Why consider Clarvia instead?
Thoughtworks genuinely earned their reputation for engineering excellence and thought leadership. The difference is focus and fit. Thoughtworks is a large consulting firm that does AI among many things. Clarvia is a small agency that only does AI product development. If your need is specifically "build me an AI product fast," you are paying for a lot of overhead at Thoughtworks that has nothing to do with your project.
Does Thoughtworks deliver faster with their 3-3-3 method?
The 3-3-3 method (assess, pilot, scale in 3-week blocks) is a solid framework. In theory, you get enterprise-grade AI in about 9 weeks. In practice, enterprise procurement, legal reviews, and stakeholder alignment typically add weeks or months before the 3-3-3 clock even starts. Clarvia skips that overhead and starts building from day one.
Can Clarvia handle the same technical complexity as Thoughtworks?
For AI product work, yes. Our team has deep experience with LLMs, ML pipelines, real-time inference, and production AI systems. Where Thoughtworks has an edge is in large-scale enterprise architecture — if you need 50 engineers across 5 time zones working on a multi-year platform modernisation, that is their strength, not ours.
What if my company requires working with a large consultancy?
Some procurement policies require working with firms above a certain size or revenue threshold. If that is a hard requirement, Thoughtworks is a solid choice. If you have flexibility, consider running a focused AI product engagement with Clarvia alongside your broader enterprise work with a larger consultancy.
