About us
Digital built for business that means business.
KENOSONICKenosonic Interactive is a Johannesburg-based digital agency focused on one thing: helping South African SMEs build a credible online presence that actively drives growth.
We combine web development, digital marketing, and brand & content into a single, coherent offering — so you don't have to manage three different agencies to get one consistent result.
The founder
Shumani Steven Rerani
Founder & Lead Strategist
Kenosonic grew out of a simple observation: most digital agencies that serve SMEs either charge enterprise prices or deliver template-level work. There was a gap for something in between — genuinely custom work at a price point that makes sense for a business turning over R2–20M a year.
Before starting the agency, I spent years working across web development, marketing strategy, and brand design — often for the same clients simultaneously. That breadth is now the agency's core offering: you get one point of contact who understands all three disciplines, and how they interact.
We work with a small number of clients at a time, and I'm involved in every project from strategy through delivery. That's not a pitch — it's a deliberate constraint that protects quality.
// “I'd rather do fewer projects exceptionally well than more projects adequately. That's the whole model.”
Four principles. Non-negotiable.
VALUESNo fluff. No jargon.
We explain what we're doing, why it matters, and what you can expect — in plain language. If we can't justify a decision to a non-technical client, we rethink it.
Small roster. Full attention.
We work with a deliberately small number of clients at any given time. That means your project gets senior attention throughout — not handed off to a junior after the sale.
Outcomes over outputs.
Delivering a website is not the goal. Delivering a website that increases enquiries is. Every project is scoped around measurable business outcomes, not just a list of deliverables.
Built for South Africa.
We understand the local market — the payment gateways, the data costs, the WhatsApp-first customer behaviour, and the constraints of an SME budget. We build for reality, not theory.
Our toolkit
Best tool for the job. Always.
We don't lock clients into a single platform or tech stack. We recommend the right tool for your specific situation — whether that's a custom Next.js build, a WooCommerce store, or a simple well-configured WordPress site.
