Designing a People OS: How to Hire After a Funding Round

Dec 10, 2025
By Alexis Joseph Merritt

Raising capital is exhilarating. It validates your product and buys you runway to build – and hire the builders. But it also raises the most important question founders face: How do we scale what makes us special without breaking it? 

Many founders treat hiring as a downstream HR problem or a to‑do list for a recruiter. In reality, your People strategy is a design challenge before it’s a hiring challenge. The People operating model you design in the first 90 days after a round sets the trajectory for the next 18 months. If you don’t build it intentionally, you’ll fill the gaps with ad‑hoc decisions, one‑off deals, and unhelpful heroics.

This guide is for founders at two key inflection points: when you’ve just raised a new round of funding and need to accelerate hiring, and when you’re about to make your first leadership hire (your first VP/head‑of‑function or manager‑of‑managers). The advice applies to both because the work is the same: design an operating system that scales.

The state of play in 2025

Founders are operating in an environment defined by opportunity and uncertainty. A recent survey of 1,500 U.S. early-stage founders shows that while 87% of companies feel more confident about their financial prospects compared to 2024, they are also running lean and looking for leverage. 

AI adoption is a major driver of growth: among startups that have embraced AI, 79% say they’re hiring more because of AI and 68% are actively scaling team size. These companies are three times more likely to be actively scaling and twice as likely to be raising larger rounds. At the same time, costs are rising across the board – from customer acquisition to infrastructure to talent – and most founders expect to spend even more in the year ahead. 

Here are three foundational truths I’ve observed over my career – consider these before you get started:

Designing your operating model

Growth capital should buy you capacity and resilience, not just more people. So you’ll want to design your organization first, then hire into it. The aim of People strategy is to create a cohesive operating model that unlocks speed without making hasty decisions.

Whether you’re posting the first job after your raise, filling the next ten roles, or hiring your first head‑of‑function, you’re not ready to hire until you have clarity on five foundational areas. These aren’t nice‑to‑haves, they’re the difference between scaling cleanly and scaling into chaos. Your operating model is the infrastructure that determines whether your team moves fast or gets stuck in meetings. It’s not about being rigid; it’s about being explicit. 

As you scale, certain metrics tell you whether your operating model is working or breaking under load. These aren’t vanity metrics – they’re early warning signals that something needs adjustment. Watch for:

Hiring at pace without lowering the bar

Once your operating model is clear, hiring becomes dramatically easier. When you move into open requisitions, optimize for structure that increases signal, not process that slows you down. Here are some important artifacts to help you hit velocity:

Keep in mind: hiring and onboarding is your first VP or head-of-function hire is different from every hire that came before it. The role is less defined, the stakes are higher, and the onboarding window is shorter. Most founders under-scope this hire. Here’s how to set it up properly as you write the JD:

People debt and how to pay it down 

Every fast-growing company accumulates people debt, when companies have fallen behind on supporting the infrastructure employees need to do their jobs (like goals and career tracks.) It’s not a moral failure, it’s a natural consequence of moving quickly. The problem isn’t having debt, it’s not knowing what debt you have or how to pay it down. 

Growth exposes every corner you cut, and the post-funding / pre-hiring boom is the perfect time to assess. The common debts: 

Dept typeHow it shows upHow to pay it down
Compensation driftOne‑off exceptions that don’t age wellPublish ranges and refresh logic
Process sprawlTools before clarityRemove steps that don’t protect quality or speed
Title inflation Promises made to close candidatesPublish a title policy tied to scope
Feedback avoidance High standards unstatedEstablish simple goals plus feedback cadence 

Every adjustment you make here compounds. Addressing people debt early builds trust, creates stability, and keeps your growth sustainable. The goal isn’t to eliminate debt entirely, but to manage it deliberately so your systems scale with your ambition.

Founder Checklist for People Strategy

Use this as your checklist and share it with anyone who’s helping you scale the team: 

Minimal Templates 

Templates don’t replace judgment, but they do create consistency and speed up decision-making. Here are three core templates you can adapt immediately. Each one includes the minimum structure needed. Add detail as needed, but resist the urge to over-engineer.

Scorecard (leadership) 

Use this to align on what success looks like before you start interviewing.

Offer memo one‑pager 

Use this to ensure candidates understand the full picture before they sign.

 30-60-90 onboarding

Use this to set clear expectations and measure progress for new leadership hires.

90‑day People Strategy Plan

Here’s the concrete 90-day timeline to get from “we just closed the round” to “we’re ready to hire and onboard at speed.” This isn’t theoretical; it’s the exact sequencing that prevents the most common scaling failures. Use it to prepare your team to scale.

T–90 to T–60: Design and alignment 

T–60 to T–30: Instrument and stage 

T–30 to T–0: Execute and reinforce
