[Click To Learn More About & Get Your Tickets](https://aagc.africa/?mc_cid=294c8e0d0d&mc_eid=UNIQID)
This May in Accra, as part of Africa Day celebrations, the Timeless Women of Wonder Foundation (TWOWF) is convening leaders, investors, policymakers, and operators from across sectors in Africa through the Accelerate Africa’s Growth Connect (AAGC)—a platform designed not just for dialogue, but for partnerships and tangible outcomes.
If you’re looking to explore investment and trade opportunities, build meaningful relationships on the continent, or deepen your engagement with Africa’s growth story, this is your invitation into the room where that becomes possible.
AAGC sits at the intersection of influence, access, and execution—bringing together those actively shaping Africa’s economic transformation and global competitiveness.
What makes it stand out isn’t just who is in the room— it’s what the room is built to enable. Across two powerful days, you’ll gain direct proximity to:
-Policymakers and government leaders shaping national agendas
-Investors and business leaders unlocking capital and opportunity
-Innovators and entrepreneurs building across key sectors
-A global network aligned around growth, collaboration, and impact
-Curated deal rooms connecting capital with real opportunities
From high-level dialogue to investor forums, curated networking, and deal rooms — this is where ideas evolve into partnerships, and partnerships translate into impact.

Martins Lane will be closed to cars but marchers can enter at Mannakee Street. The parade procession starts at 10:30 am.
This year's parade theme is "The Magic of America". Feel free to decorate your bike with red, white and blue and a little sparkle.

Ensuring Software Quality in the world of AI Developers - Matt Eland
**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you.
The building address is 4450 Bridge Park
The entrance is 6620 Mooney St, Suite 400
You will need to scan your ID at the door to get a visitor badge.
**Abstract**
Like it or not, AI agents are now capable of turning a quickly written paragraph of requirements into a pull request that is ready to be integrated into real-world production applications and it's now our responsibility to make sure AI doesn't go rogue and take down prod - or corrupt our data by misunderstanding the requirements or our existing schemas. In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod.
