How to plan headcount as Professional Services Founders
You're a 12-person consultancy and headcount planning means exporting your HubSpot pipeline to a Google Sheet, guessing which deals will close in time to justify the next hire, and cross-referencing that against a Harvest utilization export you had to download manually. You do this quarterly, it takes most of a Friday, and the moment you finalize the model your pipeline changes. You don't have a finance hire. You don't have an HR system. You have a spreadsheet that's already wrong by the time you share it with your co-founder, and a gut feeling about whether you can afford a senior consultant in Q3.
What you'll set up
Apps, data, and prompts
The combination of Starch apps, the data sources they pull from, and the prompts you use to drive them.
Starch syncs your Stripe data and your Plaid bank transactions on a schedule — those are the live actuals that power the burn and runway calculations. Connect HubSpot from Starch's integration catalog; the agent queries your deals pipeline live when the headcount model needs weighted pipeline revenue. Harvest and Float, if you use them, are reachable through Starch's integration catalog or automated through your browser — no separate API setup needed.

Q2 2026 Hire Decision — 12-person consultancy, April planning cycle
| Plaid cash balance (operating account) | 387,000 |
| Stripe MRR (retainers + project billings) | 94,000 |
| Monthly payroll + contractor cost (current team) | 71,000 |
| Software, travel, overhead (Plaid categorized) | 8,400 |
| Net monthly burn (current) | 14,600 |
| Implied runway at current burn | 2,650 |
| Cost of one senior hire (fully loaded monthly) | 12,500 |
| Projected net burn post-hire (no new revenue) | 27,100 |
| HubSpot pipeline — weighted value (35% close rate) | 210,000 |
Your Starch runway dashboard shows $387k in the operating account and $94k in Stripe MRR against $79.4k in total monthly costs — about 26 months of runway at current burn, which feels comfortable. But the scenario model tells a different story when you layer in the April hire: a senior consultant at $12.5k fully loaded per month drops net burn to $27.1k immediately, cutting implied runway to about 14 months if the HubSpot pipeline doesn't convert. The weighted pipeline value is $210k — but that's spread across Q2 and Q3 closes. Starch builds a scenario that assumes 35% close rate on Q2 deals only ($73.5k in new ARR, or $6.1k/month incremental Stripe revenue starting June), showing the April hire breaks even by August and extends to a July hire scenario where you're in a safer position but losing six weeks of onboarding time on a deal you're 80% confident will close. You share the Starch link with your co-founder. The conversation takes fifteen minutes instead of a Thursday afternoon.

My pipeline is in a Google Sheet, not HubSpot. Can I still build a headcount model?
We use Harvest for time tracking and Float for capacity planning. Does Starch replace those?
How current is the data? I need this to reflect this week's pipeline, not last month's.
Is Starch SOC 2 certified? We handle sensitive client data.
We use QuickBooks as our accounting system. Can Starch pull our actual payroll and contractor costs from there?
Can I model different utilization assumptions, not just hire timing?
