17 Mar Nineteen58: Building AI Agents That Actually Get Things Done

Innovation City brings together companies working at the frontier of technology, business, and customer experience. One of our newest members, Nineteen58, is an AI-native services company focused on building custom AI agents that help enterprises solve real operational problems, particularly in customer acquisition, service, and retention.

We spoke to Sebastian McIntosh, Client & Growth Lead at Nineteen58, about the company’s approach to agentic AI, the challenge of overcoming chatbot scepticism, and why good old-fashioned relationships still matter in a digital world.

Q: Tell us about Nineteen58 and the problem you set out to solve.

We are an AI-native services company that builds custom AI agents for enterprise businesses. If you’ve ever lost the will to live while listening to elevator music on hold, you’ll understand exactly why we’re needed!

We enable companies to interact with their entire customer base at a scale that traditional call centres simply can’t match. Imagine being able to resolve every single customer’s problem in real time, 24/7, without breaking a sweat.

Q: Can you give us a practical example of how your product or service works?

Picture this: you need to call your insurer to change your plan. Usually, you’re met with a robotic “Press 1 for X, Press 2 for Y,” followed by a 30-minute wait to speak to a human.

Now imagine your insurer uses a Nineteen58 agent. You call, and the agent instantly answers:

“Hi [Your Name], how can I help you today?”

It knows it’s you because your number is linked to your profile. You explain what you need, the agent securely verifies your identity, accesses your account, and updates your plan right then and there.

No queues. No endless menus. Just a seamless, intelligent conversation available 365 days a year.

Q: What are some of the challenges you’ve faced as a startup?

Our biggest hurdle was overcoming the dreaded “chatbot stigma.” We had to convince people that we weren’t just building another frustrating, rules-based bot that loops you back to the main menu.

Beyond that, building enterprise-grade AI means navigating incredibly strict data and privacy compliance requirements. We tackled this challenge directly to ensure our clients’ data is locked down tight.

Q: What’s new or exciting happening at Nineteen58 right now?

We’re actively growing the team and expanding our capacity to take on more clients.

We’re also going live with a couple of very large clients soon, and we’re looking forward to sharing more details once those launches are official!

Q: What’s on your business growth wish list?

Expanding our Cape Town engineering team is high on the list. If you’re a brilliant engineer who is slightly obsessed with Agentic AI and enjoys working closely with clients to build game-changing technology, we’d love to meet you.

We’re also always looking for businesses ready to rethink how they interact with customers at scale.

Q: What is your take on doing business in South Africa?

It might sound ironic coming from an AI company, but the truth is that personal relationships and trust remain the cornerstone of doing business in South Africa.

We may live in a digital world, but popping over to a client’s office for a face-to-face conversation is still one of the best ways to build a lasting partnership.
