How to plan headcount on Starch
Headcount planning is the process of deciding who you need to hire, when, and what you can actually afford to pay them — and then holding that plan up against your cash position often enough that you don't get surprised. It sits at the intersection of financial modeling and operational reality, which is why it tends to fall through the cracks: finance thinks HR owns it, HR thinks finance owns it, and the founder ends up doing it in a spreadsheet on a Sunday night before a board meeting.
What the workflow looks like varies — how many open roles you're managing, what your burn tolerance is, whether you're modeling against a raise or against revenue — but the core problem is the same everywhere: you need a living view of your hiring plan, not a document you update twice a year.
On Starch, you describe the headcount model you want — roles, start dates, fully-loaded costs, department splits — and Starch builds it against your actual Stripe revenue and Plaid bank data so the numbers stay current without manual exports. The result is a hiring plan that updates alongside your real financials: you can see what adding two engineers in Q3 does to your runway, compare a conservative and aggressive scenario side by side, and walk into a board meeting with a current answer instead of a stale one. The Scenario Analysis and Runway Analysis apps give you the financial backbone; you layer your headcount assumptions on top and the cash impact shows up immediately.
Why it matters
Hire too fast and you hit a cash wall six months before you expected. Hire too slow and you miss the window to build what the business actually needs. The difference between those outcomes usually isn't a bad decision — it's a plan that was built in isolation from the real cash position, or one that was accurate in January and never touched again. A current, scenario-tested headcount plan lets you move faster with more confidence because you've already seen what each choice costs.
Common pitfalls
Using fully-loaded cost as an afterthought — modeling salary only and ignoring benefits, payroll taxes, and equipment adds 20-30% to every hire and blows your runway calculation. Treating the headcount plan as a separate document from the financial model, so every assumption change requires two updates instead of one. Setting start dates once and never pressure-testing them against actual hiring timelines — most roles take 60-90 days to close, and a plan that assumes 30 days is already wrong. Modeling a single scenario instead of a range, so any change to the revenue plan requires rebuilding from scratch.
