Sarah Mapes Didn't Set Out to Be an Operations Founder—Until She Realized Companies Needed One

Sarah Mapes officially started her company in 2023, but her path as a founder began long before that. She just didn’t know it yet.

Across a range of back-office roles, Sarah kept finding herself inside the same kind of organizational tangle: smart people, good intentions, and plenty of tools, but no clear way for work to move across the business. Hand-offs were inconsistent. Systems didn’t match the way teams actually operated. Critical knowledge lived in one person’s head. Eventually, Sarah realized that untangling all of that wasn’t just a side effect of her work. It was her work.

Raised in a moderately entrepreneurial household, Sarah had always imagined she might build something of her own someday. When she and her partner decided to make a geographical move, that someday arrived. Sarah said goodbye to a role she loved—and the stability that came with it—to build ThinkOps.

Today, ThinkOps is an operations and HR consultancy that helps growing companies fix the messy middle of growth, replacing broken hand-offs, untrusted systems, and one-person processes with clearer operations, stronger accountability, and execution that can actually hold up as they scale.

Here, Sarah shares how the roles that came before shaped her founder journey, how she works to transform businesses, and what might come next.

What are some of the most meaningful impacts your work has had so far?

I love it when teams feel relief. From the outside, a lot of what I do isn't flashy. It might look like boring process mapping, system clean-up, governance design, or project leadership—but underneath that, the impact is very human. It's the employee who no longer has to chase five people to get one answer. It's the HR team that finally has clarity on who owns what. It's the organization that no longer has to rely on one person's memory to keep a critical process moving. 

I've helped organizations navigate major HRIS and payroll transformations, redesign operating models, and improve cross-functional workflows. The throughline is always the same: helping people do good work with less confusion, less rework, and fewer preventable fires. That's the impact I care most about.

What’s the biggest misconception others have around entrepreneurship?

That flexibility means ease. Entrepreneurship does give you flexibility, but it also gives you full ownership of every decision, every mistake, every slow month, every client experience, and every internal process you haven't had time to build yet. You're not just doing the work; you're finding the work, pricing the work, managing the work, delivering the work, improving the work, and occasionally wondering why your inbox has become a second business. 

The freedom that comes with entrepreneurship is real, but so is the responsibility. For me, the trade-off has been worth it, but people underestimate how much discipline and self-trust it takes to build something without the structure of a traditional organization around you.

In what ways have your upbringing or past experiences contributed to how you operate as a leader?

As we generalists say, I've had a squiggly road! I studied business administration in college and later earned a master's in international relations. Somewhere in between, I worked retail floors, waited tables, and moved through consulting, higher ed, family office and private equity, recruiting, and hospitality. I've been an EA, a project manager, an HR partner, and an operations leader. I was almost always the person sitting between very different worlds: the big-picture decision makers and the people who had to make things actually function day to day. I learned to move between both worlds and translate one to the other. 

My New England roots shaped the rest. I'm pragmatic, allergic to hype, and far more interested in whether something works than whether it sounds impressive.

What have you learned about building a team and a support network around yourself?

I've learned that independence doesn't mean doing everything alone. When you start a business—especially as a solo founder—it's easy to believe you should be able to figure everything out yourself... but that gets isolating fast. The right support network gives you perspective, accountability, encouragement, and a much-needed reality check at times. It doesn't always have to look like a formal team, either. It can be other founders, trusted advisors, contractors, or clients who challenge your thinking. 

What’s next for you and your career?

Right now, I'm focused on deepening the kind of work I do best: complex HRIS and operating model transformations for organizations in operationally demanding industries. As ThinkOps grows, I'm being more intentional about building a network of people who are stronger than I am in certain areas so the business gets better because the right people are contributing to it, not because I'm the only one with answers. I'm not chasing growth for its own sake. Instead, I want to build something that stays excellent, stays sustainable, and keeps letting me do work that actually matters to the clients I take on.

Describe the journey you’ve had in a few sentences. Would you do it all over again?

Squiggly, unglamorous, and completely worth it. I left a job I loved and moved out-of-state to start a business with no guarantee it would work, and it remains one of the best decisions I've made. The path hasn't been a straight line, but every winding part of it gave me something I use now. 

Would I do it all over again? Without hesitation.
