Tech-based SMEs rely on scientific or technological knowledge and innovation. They face several risks including a lack of collateralizable assets, long gestation periods, dependence on niche markets, and high costs of R&D and skilled labor. Their financing needs are greatest during the seed and startup stages as they develop prototypes and work to gain market acceptance, though risk decreases as they grow and expand. Financial institutions can help support tech-based SMEs through priority lending, loan schemes, expertise in valuation, and assistance with supply chains and marketing.
