Why Your Series A Hire Failed at Series C (And How to Avoid It)

Here's something I've watched repeat for over 20 years in executive search: A founder hires a VP at Series A. The hire crushes it. The company grows. Then, somewhere around Series C, that same executive starts drowning. Performance reviews get awkward. The board starts asking questions. Eventually, the founder has to make a painful call.

The instinct is to blame the executive. They "couldn't scale." They "hit their ceiling." But that framing misses what actually happened.

The executive didn't fail. You promoted them into the wrong race.

The Red Bull Problem

Formula 1's Red Bull Racing has one of the most successful driver development programs in motorsport history. Sebastian Vettel, Daniel Ricciardo, Max Verstappen. Yet for the past decade, they've struggled with a pattern that should sound familiar to any founder who's watched a star hire flame out.

In 2019, Red Bull promoted Pierre Gasly from their junior team to race alongside Verstappen. Gasly had performed brilliantly at the lower level. He was ready for the big leagues. Except he wasn't. After 12 races without a single podium, Red Bull demoted him back to the junior team.

Here's what happened next: Gasly won the 2020 Italian Grand Prix. Same driver. Same talent. Different level.

The pattern kept repeating. Alex Albon was promoted mid-way through his rookie season, struggled against Verstappen, and was dropped after 2020. He's now consistently delivering strong results at Williams. Daniil Kvyat was demoted after just four races in 2016. Liam Lawson lasted two races in 2025 before being sent back down.

Christian Horner, Red Bull's team principal, eventually admitted the obvious: "In recent years, we may have promoted certain drivers too early."

Then there's Carlos Sainz. He spent nearly three seasons with the junior team, was never promoted to the Red Bull team despite strong performances, and eventually left the program entirely. He's now a multiple-race winner at Ferrari. The talent was always there. Red Bull just couldn't see how to use it at the right level.

Builders vs. Scalers

Index Ventures coined a useful distinction: "Builders" versus "Scalers." At the early stage, you need Builders. People with T-shaped skills who can wear multiple hats, create from nothing, and thrive in ambiguity. At later stages, you need Scalers. Managers of managers who can build repeatable processes and run predictable systems.

The framework is helpful, but it misses something crucial. The problem isn't that Builders can't become Scalers. Some can. The problem is that founders rarely diagnose which type they actually hired, and they almost never have a plan for the transition.

This is where The Founder's Paradox shows up in executive hiring. The same instincts that helped you identify a great Series A hire will mislead you at Series C. You hired for energy, scrappiness, and versatility. Those qualities don't disappear. But at Series C, you need something different: systematic thinking, delegation muscle, and the ability to operate through layers of management.

Gasly didn't lose his speed when he joined Red Bull. He was the same driver. But the demands of a championship-contending team require different capabilities than a midfield outfit. The pressure is different. The systems are different. The margin for error is different.

The Warning Signs You're Missing

Here's what I see founders miss. The executive who crushed Series A starts showing strain around Series B, but the signs are subtle. They're working harder than ever. They're in every meeting. They're the first to arrive and last to leave. From the outside, it looks like dedication. From the inside, it's a sign they've lost the ability to delegate.

Ben Horowitz at 16z put it well: "If you have somebody who's really doing the job, they're teaching you about how the function should expand. If you're giving them more ideas than you're getting out, that's probably not going to work."

The data on startup executive tenure tells the story. The median job tenure for startup employees is just two years, compared to 4.2 years in the broader economy. For senior go-to-market hires at pre-Series B companies, over 65% leave within 18 months. The average VP of Sales tenure in tech has dropped from 26 months to 19 months over the past decade.

These aren't failure statistics. They're misalignment statistics. Companies and executives are constantly discovering, too late, that they're in the wrong race together.

The Hire-for-Stage Principle

The solution isn't to avoid early-stage talent. It's to hire with clear eyes about what each stage requires, and to build transition plans before you need them.

Think of it like tire compounds in F1. Different compounds perform optimally under different conditions. The soft compound that gives you grip in qualifying will fall apart over a race distance. The hard compound that survives a long stint won't give you the pace for a final-lap battle. Neither compound is better. They're designed for different conditions.

At Series A, you need executives who can build the plane while flying it. People comfortable with ambiguity, capable of doing the work themselves while also hiring their first team members. The job at this stage is fundamentally about creation.

At Series C, you need executives who can run a system. People who've built and led teams of 50 or more, who understand how to manage through layers, who can create predictable outcomes from repeatable processes. The job at this stage is fundamentally about optimization.

Some executives can make that transition. Many cannot. The question isn't whether your Series A hire is "good" or "bad." The question is whether they have the specific capabilities your Series C company requires.

What Smart Founders Do Differently

The founders who navigate this well do three things:

First, they hire for the stage 12-24 months ahead, not the stage they're in today. If you're at Series A and planning to hit Series B in 18 months, you need someone who can operate at Series B scale. This means accepting that your new hire might feel slightly "over-qualified" for your current needs. That's the point.

Second, they have honest conversations about trajectory early. Before the hire, discuss what the role looks like at 2x and 3x the current scale. Ask the candidate directly: "Have you done this before? Do you want to do it again?" Some people genuinely prefer the building phase. That's not a weakness. It's self-awareness.

Third, they proactively build transition plans. The best-case scenario isn't that your Series A hire scales forever. It's that you have a clear path for them when the company outgrows their optimal contribution level. Maybe that's a different role. Perhaps that's a graceful exit with equity intact and relationships preserved. The worst outcomes happen when these conversations are avoided until a crisis forces them.

The Sainz Path

Carlos Sainz spent years being told he wasn't quite ready for Red Bull's top team. He watched Verstappen get promoted over him. He watched Gasly and Albon get chances he never received. Eventually, he stopped waiting and built his own path through Renault, McLaren, and finally Ferrari.

Today, Sainz has multiple Grand Prix victories. He's beaten teammates who were supposed to be the stars. He found the right level, even if Red Bull couldn't see it.

Your Series A hire who struggled at Series C might be a Sainz. The talent is real. The drive is real. They just need to find the right race. And you, as the founder, need to recognize that keeping them in the wrong seat hurts both of you.

The hardest part of leadership transitions isn't making the call. It's making it early enough that everyone lands well.

Pierre Gasly won at Monza because Red Bull had the honesty to recognize the mismatch. Your company deserves the same clarity.
