Gusto co-founder @tomerlondon on how AI changed how they build product: "We've been doing this for 15 years. Every time a new technology comes in, you have to ask: how does this let us solve the problem for the customer better? AI is a fantastic example. There are capabilities and there are interfaces. A capability is: instead of building your employees' timesheets manually, you click a button and Gusto figures out the optimal timesheets for you. We built Cofounder as an interface. The idea is, what if instead of logging into you never needed to log in at all? You could just text Gusto and run your whole back office through text, like you’re talking to your co-founder over iMessage, Slack, or WhatsApp. It flips the model. In the old SaaS world, you log in and dig through menus, primary, secondary, tertiary, to find the one thing you need. Cofounder is proactive. It reaches out to you when there's something you should know, instead of making you go hunt for it. Here's what proactive looks like. Cofounder wakes up in the morning, looks over your account, and asks what it can do to help. It might say: you have seven PTO requests to approve before payroll, five look totally ordinary so I approved those, the other two I need you on. All over text. Or it says: payroll's set, benefits are handled, the new hire's onboarding is ready. But I noticed you've been hiring engineers and you're not claiming R&D tax credits, and those could save you $15,000 next year. Want me to set that up? An extra $15K, just from the software noticing."
