Darius Contractor on Why You Can Only Grow People 20% Per Year

The 20% Rule That Changes How You Hire and Promote

Most managers eyeball growth potential. Darius Contractor quantifies it.

After scaling teams at Facebook, Dropbox, Airtable, and now Otter.ai, he's landed on a simple number: you can push most people to be about 20% more capable than they currently are in a given year. Less than 5 or 10%, they get bored. More than 30%, they get overwhelmed.

Every year, your systems can double or triple or 10x, but your people usually can't 10x in a year. You have to have a little bit more of a speed of light as to how much they can learn, how much they can take on.

This math directly informs hiring decisions. If you're considering layering someone, that new hire needs to be at least 50% better at the role, maybe even twice as good. Otherwise, the person below them will think, "I could have done that job if you just believed in me." And they'd be right.

The alternative? Give that person support and coaching so they can stretch into the bigger role. If someone only needs to grow 30% to handle the next level, don't hire over them—grow them.

The Dinner Plate Framework for Composing Roles

Darius doesn't just think about what the company needs from a role. He thinks about what makes someone actually want to show up.

He breaks down every job into percentages: 30 to 70% should be things they're really good at. That's where they deliver value fast. Then 10 to 50% should be new challenges—management, AI projects, tough strategic problems. The range depends on the person's tolerance for frustration. Some people want 50% of their job to be hard and new. Others max out at 10%.

The last piece: 20 to 40% should just be enjoyable. Quiet deep work for some. Collaboration with great communicators for others. Dessert on the plate.

If you just have ice cream, that's going to be fun for a week, like offsites, right? But eventually you're going to be like, what am I really doing here? It's not very satisfying.

The trick is layering these so they overlap. If something is both a strength and a company need, that's great. If you can get three or four of these dimensions aligned in one initiative, the person will have a fantastic time.

The SEEN Exercise: Making Sure Your Team Feels Seen

Darius runs a structured exercise with every direct report, especially when someone joins his team or when the company shifts direction. He calls it SEEN: Strengths, Excitement, Growth Edges, and Needs of the company.

Strengths are what you build on. If someone is hyper-organized, let them project-manage a new exploratory effort. Excitement is what gets them out of bed. Growth edges are the hard things they actually want to get better at—management, technical depth, innovation, craftsmanship. And needs of the company anchor everything, because that's where the whole org will help you succeed.

The real trick is taking each of these bullets and combining them, like even two of them, aligning your strengths with the needs of the company is a great start. If you can get three or four, then that's a superb role where the person's just going to have a fantastic time and feel great about it.

He revisits this at least once a year in a deep dive, and touches on it monthly in one-on-ones. The first one-on-one of every month includes bundled feedback: what's going well, what's not, and how the person is tracking against the growth edges they identified six months ago.

Ask What Job They Want After the Next Job

When Darius talks career pathing, he skips the obvious question—what do you want next?—and asks what job do you want after the next job?

If someone wants to be a founder two jobs from now, they need different skills than someone aiming for a VP role at a big company. That insight shapes how Darius allocates their time today. He keeps a 10 to 20% slush fund of every employee's time for projects that partially align with company needs but deeply align with what the person needs to learn.

Someone who wants to launch a D2C brand someday? Let them run the small paid marketing effort, even if it's not perfectly in their lane. If they're delivering 80% of their core role solidly, that 10 to 20% becomes an investment in retention and growth.

The meal metaphor works here too. Some things you eat for nutrients. Some because they're delicious. Some check both boxes. A healthy role, like a healthy plate, needs both what the company requires and what the person craves.

Analogies as a Leadership Tool

Darius is known for making up analogies on the spot. His team remembers them years later—sometimes because they're helpful, sometimes because they're delightfully weird.

One favorite: imagine someone you dislike from school made your website. Suddenly you're not looking at it with a parent's eyes. You're a skeptical user with no time. Would you still click the button?

He's intentional about this. Analogies unlock lived experience. They help people apply intuition from one domain to a problem in another. And they add levity when the work gets intense.

At Otter, frameworks have names. EVILIN tracked experiment velocity and engagement lift. The dinner plate shows up in role design conversations. The 20% rule guides promotion discussions. These aren't fluff—they're shared language that makes the team faster and more aligned.
