An investment and venture-building firm.

Warren Theessen is an experienced strategy, operations and investment professional with more than a decade of multidisciplinary experience spanning asset management, entrepreneurship, business development, environmental enterprise and technology-enabled venture creation.

Warren has been associated with Northstar Asset Management, a respected boutique asset management firm, and previously founded and managed a successful wildlife management business. During this period, he also devoted five years to anti-poaching advocacy and subsequently established an independent business development consultancy. He later founded SAFE Solutions, an artificial intelligence technology venture focused on developing integrated technologies for the aquaculture and water-management sectors. As Founder and CEO, Warren assumed responsibility for corporate strategy, operational planning, product development, commercialisation, strategic partnerships, sales and market-entry execution.

This combination of analytical, operational and entrepreneurial experience is closely aligned with the purpose of Nexus Capital. Warren understands that capital alone seldom resolves the underlying constraints preventing a business from achieving its potential. Sustainable value is created by combining appropriate funding with structured financial management, strategic clarity, operational improvement and practical implementation.

As Founder and CEO of Nexus Capital, Warren is responsible for the firm's strategic direction, investment assessment and the development of opportunities capable of generating sustainable, long-term value. His role includes evaluating businesses and new ventures, developing commercial and financial models, structuring investment opportunities and working alongside founders and management teams to implement practical growth strategies.

Nexus Capital distinguishes itself from traditional private equity and growth-capital firms through its understanding of market disruption and its ability to apply innovation as a deliberate driver of growth. Rather than relying solely on financial restructuring or incremental operational improvements, the firm seeks to identify how emerging technologies, changing consumer behaviour, environmental pressures and evolving market dynamics can be used to reposition businesses, create new revenue streams and establish defensible competitive advantages.

Warren applies this perspective to both established businesses requiring capital or strategic intervention and greenfield ventures capable of addressing clearly defined industrial, environmental and commercial opportunities. His approach combines investment discipline with entrepreneurial thinking, recognising that the strongest opportunities are often created by challenging conventional business models and introducing more effective ways of operating, producing and competing.

He has a particular interest in manufacturing, industrial services, technology, sustainability and the broader green-economy sectors in which capital, innovation, technical capability and experienced management can be combined to create measurable and enduring value.

Through Nexus Capital, Warren is committed to building businesses rather than merely financing them. His leadership is centred on identifying unrealised potential, applying innovation intelligently and providing the capital, strategic direction and operational support required to convert opportunity into scalable and commercially sustainable growth.

Dianne Wiggil is an accomplished technology executive, entrepreneur and business strategist with more than three decades of experience building, scaling and repositioning businesses across telecommunications, enterprise hardware, retail technology, digital payments and artificial intelligence.

Her career has been defined by an ability to recognise the commercial implications of emerging technologies, translate innovation into viable business models and lead organisations through periods of rapid growth, transformation and market disruption. She has operated within both established international organisations and entrepreneurial ventures, giving her a practical understanding of the strategic, operational and capital requirements businesses face at each stage of their development.

Dianne participated in the development of Redline Communications, a Toronto-listed wireless network manufacturer headquartered in Ontario, where she established the emerging-markets division and secured Redline's first major carrier engagement through MTN across Africa. She was subsequently brought into 3Com as a member of the CEO's task team, contributing to the strategic and operational repositioning of the business through the period culminating in its acquisition by Hewlett-Packard.

She later served as Group CEO of South Africa's largest retail software group, whose clients included eighteen of the country's twenty leading retailers, overseeing complex technology deployments for Engen, The Foschini Group, OK Stores, JD Group, Vodacom, FurnMart and Moss Bros in the United Kingdom. As General Manager of Zapper, Dianne built the business into South Africa's largest QR-code payment platform, scaling the organisation to approximately 130 people and securing adoption by national groups including Famous Brands, Spur Corporation and Total.

This breadth of experience has given Dianne a particularly informed understanding of market disruption. She has not encountered disruption only as an external investment theme, but has worked within businesses that created new markets, challenged established operating models and required customers to adopt fundamentally different technologies and commercial practices.

At Nexus Capital, Dianne applies this experience to the identification, assessment and development of businesses capable of achieving accelerated and sustainable growth. Her role encompasses investment origination, commercial strategy, business-model development, technology assessment, operational transformation and the practical implementation of growth initiatives alongside founders and management teams.

Her contribution is particularly important in assessing how innovation can be applied to reposition an existing business, create new revenue streams, improve scalability or develop an entirely new commercial proposition. Her approach combines strategic insight with execution experience, recognising that innovation creates value only when it can be converted into a structured operating model, a credible route to market and measurable commercial outcomes.

Through Nexus Capital, Dianne is committed to working with capable founders and management teams who recognise that meaningful growth frequently requires more than additional funding — it requires the willingness to challenge established assumptions, respond intelligently to market disruption and apply innovation in a manner that strengthens competitiveness and builds enduring value.
