Upping SAโ€™s BioTech Game

The worldโ€™s regulated bio-enzyme chain is choking Africaโ€™s access to vital resources โ€“ this startupโ€™s bringing advanced biotech homeโ€ฆ

Hey, know why your shampoo works so well? Itโ€™s chock-full of enzymes from living organisms.

Eek, why? Because these proteins have a superpower: They speed up chemical interactions. And itโ€™s not just your shampoo, 90% of all detergents, most food and beverages, pharmaceuticals, skincare and textiles โ€“ in fact, nearly 50% of all chemical products sold worldwide require enzymes somewhere along the supply chain.

Jip, enzymes are big money: This $13.97 billion market (R240bn) is projected to exceed $21.9 billion (R377bn) by 2033, while the demand for chemicals will quadruple by 2050.

But, thereโ€™s only a small number of global suppliers: Primarily big Western players. Smaller labs either import reagents at razor-thin margins or settle for subpar consistency. In a word: Todayโ€™s resource-heavy enzyme production wonโ€™t cope.ย 

We need to reinvent how we make these essential materials.

The enzyme opportunity

Precision fermentation and synthetic biology tools are maturing, making smaller-scale production credible. And regulatory demands for โ€œclean labelsโ€, sustainability and local supply chains are making import reliance riskier.ย 

Not to mention the COVID-era exposed vulnerabilities in the global biotech supply.

We in SA should be asking: โ€œCan we make this ourselves?โ€

The local BioTech democratising enzymes

Immobazyme is a BioTech that utilises precision fermentation to produce high-value active protein ingredients, essentially teaching the yeast or bacteria to follow a new recipe to make valuable proteins that can be used in (amongst others) food, medicine and skincare.

We caught up with Ethan Hunter, Immobazyme Co-Founder and COO, who said they started in 2018, solving the industryโ€™s problem of losing enzymes during most manufacturing processes with a patented enzyme immobilisation filter that lets them โ€œreuseโ€ enzymes by making them โ€œstickโ€ to a reusable surface while a substrate flows through.

But that was pretty hard to scale. So they pivoted to engineering vital genes for the process: By creating genes that could express tagged proteins in bacteria, they could produce a good supply of โ€œpharma-gradeโ€ protein at scale.

At first, they focused on high-value, low-volume markets like cosmetic serums, speciality food enzymes and diagnostic labs. But theyโ€™ve just moved into some state-of-the-art facilities to aid their push into drugs and therapeutics.ย 

And if Immobazymeโ€™s patented proteins clear regulation, they wonโ€™t just ride biotechโ€™s shift toward decentralised supply, they might just anchor it in African laboratories.

Weโ€™re watching this space.

6 things we learnt in The Founder Collab

You can do entire client portals in Notion. Candice Grobler ran a live session for members, showing how to design custom client dashboards that cut inbox noise.

We got our free tickets! Members grabbed free tickets to the next Open Letter event in Cape Town โ€” another perk you wouldnโ€™t get outside the Collab.

We got invited to the Innovators Den. A special invite-only night at Old Mutual Place, JHB, with 150+ tech leaders, panel talks, breakouts and yes โ€” free gelato.

The Collab is getting MEGA new member benefits soon. We connected with some big tech suppliers, and thereโ€™s a potential host of valuable perks coming our way.

It pays to ask the community. Members helped Enrico test billing perceptions and behaviour, turning raw data into fresh insights.

Learning from other tech plays. We debated gated content + Sora2: From lead magnets to AI shopping integrations, we explored where the next monetisation plays could land.

Find your founder community. Join The Founder Collab, itโ€™s where 100+ real SA founders help each other to build better, faster every day.
