We score AI judgment,
not AI usage.
Anyone can ship what the AI wrote. Strata is the validity layer for AI-era hiring: it scores whether a candidate catches the machine when it is wrong, and proves that score predicts performance.
What is Strata?
A full hiring workflow where candidates do real work with AI, every interaction is captured, and a panel of agents scores the judgment behind it. Whether you are a startup making your first engineering hire or a team screening thousands, the decision you get is one you can defend.
Mission
Kill the guesswork in technical hiring. Strata scores the one skill that decides the AI era, catching the machine when it is confidently wrong, and ships every recommendation with the evidence to back it.
Vision
A world where every technical hire is provable: scores anchored to real outcomes, funnels audited for bias, and judgment, not keyword luck, deciding who builds the future.

From the founders of Reskilll & MastryHub.
Strata was not built on a hunch. It comes from years of running developer ecosystems and watching thousands of builders work with AI, up close, at scale.
Skill. Upskill. Reskilll.
India’s leading hackathon platform, with a 6M+ developer pipeline across 20+ countries. Reskilll runs skilling programs and hackathons with the biggest names in tech, and its AI gateway powers Strata’s model access.
Where builders ship cool stuff.
The all-in-one Web3 hackathon platform: host, discover, and join hackathons and builder events across the blockchain and crypto space, with persistent Community Hubs between them. Up next: the MastryHub Protocol, monetizing the open-source ecosystem.

“Partnering with Reskilll for the Digifest Hackathon was a game-changer for TiE. Their ability to mobilize and mentor tech talent at scale is exactly what India’s ‘Bharat’ startups need to go global.”
Mahavir Pratap Sharma
Past Chair, TiE Global Board of Trustees
“625 teams, 95 teams qualifying. The scale Reskilll brought to our AI hackathon was incredible. They handled everything while we focused on the innovation.”
Meta India
Meta Llama AI Hackathon, Oct 2024
“I have judged multiple hackathons across Web3 and AI ecosystems, and MastryHub stands out for how seamless it makes the entire experience. The platform made it easy to review projects, compare teams, and collaborate with other judges without any friction.”
Siv Souvam
Builder · Ex-Microsoft · OG Club (acq. Brinc)
“India’s largest aviation hackathon: 500+ innovators, 120+ teams, and business solutions that went straight into our operations roadmap. Reskilll made it possible.”
Vistara Airlines
Vistara Hackathon, Oct 2017
“As a first-time hackathon judge, I expected the evaluation process to be overwhelming. MastryHub made it surprisingly structured, from accessing submissions to reviewing demos and scoring projects. The platform made it easy to focus on the ideas rather than figuring out the process.”
Aditya Walia
Solutions Architect, HyperVerge
“A big congratulations to Reskilll and OMOTEC for envisioning this brilliant initiative and to the Microsoft Azure Developer Community for supporting it.”
Dr. Manish Malhotra
Founder, Futred Innovation Studios
“This was my first time judging a hackathon, and MastryHub made the experience very smooth. Everything from project submissions to judging criteria was clearly organized, which made reviewing teams straightforward and enjoyable.”
Aaron Mathew
Junior Solutions Architect, HyperVerge
“Reskilll has been at the forefront of technology evangelism for young students of our country, creating an exemplary ecosystem utilising their network effect at top-notch organizations.”
Dr. Monit Kapoor
Professor & Dean CSE, Chitkara University
“What stayed with me most was learning that the students had built the app themselves. The product itself also left a strong impression: the UI feels simple and crisp, the experience is smooth and easy to navigate, and overall it felt like a thoughtfully built app.”
Bhuvana
Marketing, ETHMumbai
“Hosting our hackathon on MastryHub was a great experience. The interface is intuitive, the workflow is smooth, and the platform made it easy to manage everything end-to-end. One of the most well-designed tools we have used for running hackathons.”
Arjit Kulkarni
Organizer, MastryHub · Dayananda Sagar University
“The sessions were interactive, and our team appreciated connecting with leaders from the tech industry.”
Arjun Patel
Community participant, Reskilll

The founders.
The same team building Reskilll and MastryHub, now putting years of builder-ecosystem experience behind one question: can this candidate catch the machine when it is wrong?
“Great technology doesn’t change the world by existing. It changes the world by being adopted. And adoption starts with education, community, and the right entry points for every kind of learner.”
Sameer KatteCo-Founder · Dev, Strata“Interviews reward rehearsal. Real work rewards judgment. We built Strata so the second one finally decides the hire, with the receipts attached.”
