Cape Town-based AI software startup Tennsa has raised pre-seed funding from Oakvale Invest to scale its platform and accelerate its push to help businesses move from fragmented legacy workflows to agentic intelligence. Its Tennsa OS acts as an always-on intelligence layer across business systems including accounting, inventory, CRM, email, calendars and banking. Beyond Tennsa OS, the company provides AI strategy and guidance, custom AI development and integration, and AI training. The investment comes as enterprises increasingly move beyond experimenting with standalone generative AI tools and begin looking at ways to embed AI into core business processes. For Oakvale, Tennsa represents the first investment in a portfolio being built around artificial intelligence at the earliest stages of company formation.
