Young Nigerian built an AI-powered skill verification platform that gives learners a trusted way to prove what they know beyond certificates and CVs.
A certificate can show that someone completed a course.
It does not always show that the person can actually do the work.
For Winner Umukoro, that gap became increasingly difficult to ignore while interacting with students, developers, self-taught learners and people trying to build careers in technology.
Many had taken courses, built projects and developed valuable skills, but still struggled to convince employers and institutions that they could apply what they had learned.
That experience led Winner to build Winumu around a simple idea: instead of asking people to rely only on certificates, give them a credible way to prove their abilities.
From Learning to Proof
Traditional skill verification often depends on certificates, CVs, portfolios and manual assessments.
While these can provide useful information, they do not always give employers a consistent way to understand what someone can actually do.
Winumu approaches the problem through AI-powered challenges, evidence of practical work and a public Proof Portfolio.
The platform is designed to help learners verify their skills and create tangible evidence that can be shared beyond the classroom.
Its philosophy is captured in a simple line: Don’t just learn it. Prove it.
For Winner, this is particularly important for people who may have taken alternative routes into technology. A learner does not necessarily need to have attended a prestigious institution to develop a valuable skill, but they still need a credible way to demonstrate it.
Building Without Outside Capital
Winner started Winumu without outside capital, relying on a background in software engineering and AI/ML, experience in EdTech and a network built within the technology community.
Winner built winumu alongside Opemiposi Olusinde who is the Product Manager, a first class computer science graduate from babcock university bringing experience in product and software development.
The early challenge, however, was not simply building the technology.
It was building trust.
Institutions are careful about anything that affects how they assess or certify learners, while learners can also be skeptical about having to prove skills they have already spent time developing.
Winumu therefore had to demonstrate that it was not simply another assessment tool.
The objective was to make existing skills more visible and credible.
Using AI to Scale Skill Verification
Technology has been central to Winumu from the beginning.
Winner recognised that if skill verification was going to reach thousands or eventually millions of learners, it could not depend entirely on manual assessment.
AI provides a way to automate parts of that process.
Winumu is built with Next.js, while AI powers its verification and coaching systems. The company initially launched with GPT-4o-mini and has since moved its core AI engine to GPT-5.5. Paystack handles its billing infrastructure.
Rather than requiring someone to manually review every learner’s evidence, the platform can analyse submitted work, generate relevant verification challenges and assess responses.
These results contribute to what Winumu calls its Compound Score, giving learners another way to demonstrate their capabilities.
The platform also allows users to build a Proof Portfolio, creating a public record of their skills and evidence.
From Individual Learners to Institutions
Winumu has grown to thousands of users, including paying Pro subscribers, while beginning to expand into institutional partnerships.
Its first confirmed founding institutional partner is Zindua School in Kenya, marking an important step in the company’s plans to expand beyond Nigeria.
Winner sees institutional partnerships as an important part of making skill verification part of the learning journey itself, rather than something that happens only after someone completes a course.
The company is also exploring partnerships with other training institutions across Africa.
As the platform has grown, Winner has learned that registrations alone do not tell the full story.
Users become more engaged after completing a verification and seeing tangible evidence of their abilities through their Compound Score and Proof Portfolio.
That has shifted Winumu’s focus toward activation and actual product usage rather than simply growing registration numbers.
Building for Africa’s Changing Skills Economy
The problem Winumu is addressing is particularly relevant to Africa’s growing technology workforce.
Many people enter tech through bootcamps, online courses, self-directed learning and practical experience.
For these learners, traditional credentials may not always capture the full picture of what they can do.
Winumu is attempting to create another layer of credibility around demonstrated ability.
The company’s progress has also been recognised through several competitions and programmes.
Winumu made the Top 30 at the MTN Nigeria Pitchathon 2026, won first place in the Coding Category at the DevCareer x Raenest Hackathon, progressed to the next stage of the Startup Abuja Innovation Challenge with AWS and Transnet Cloud, and was accepted into the AyaHQ x Lisk Incubation Program.
The company has also received $100,000 in Microsoft for Startups Azure credits.
For Winner, these milestones provide validation as Winumu continues to develop the product and expand its reach.
What Comes Next for Winumu
Winumu wants to expand across Africa and become infrastructure for skill verification across different forms of technical and professional learning.
The company’s near-term targets are 5,000 active users and $8K–$12K in monthly recurring revenue within six months, followed by 25,000 active users and $45K–$60K MRR within twelve months.
Within 18 months, Winumu is targeting more than 50,000 active users and $120K+ MRR.
The company is currently raising between $50,000 and $500,000 through a SAFE.
The proposed allocation includes approximately 40% for product and engineering, 30% for growth and marketing, 20% for AI infrastructure and API costs, and 10% for operations and legal.
But the larger ambition goes beyond the numbers.
Winner wants to change how skills are recognised.
For someone who may not have attended a prestigious institution or followed a traditional career path, being able to demonstrate what they can actually do could become an important part of accessing opportunities.
As AI continues to change how people learn and work, the question may increasingly become less about whether someone has completed a course and more about whether they can demonstrate the skills they have acquired.
That is the space Winumu is building for.
Don’t just learn it. Prove it.
