GrowthStack
GrowthStack replaced spreadsheet-based attendance and email payroll with TimmyHR — cutting monthly payroll time from 2 full days to under 2 hours, while giving their growing team the performance infrastructure they needed to scale.

Two full days. Every month. Just to close payroll.
GrowthStack was a 40-person tech company growing at roughly 3–5 hires per month. On paper, their HR processes worked. In practice, they were a slow-motion disaster waiting to happen.
Attendance lived in a shared Google Sheet. Every Friday, the ops manager manually chased team members who hadn't submitted their hours. Remote employees in different time zones were often 2–3 days behind. By the time payroll came around, the data was a patchwork of estimates, corrections, and assumptions.
Payroll itself was managed via email threads. The HR lead would compile a spreadsheet, send it to the founder for approval, wait for responses, make corrections, and then manually generate payslips in a template document. For a 40-person team, this took approximately 2 full working days every month.
Performance reviews existed in theory — a twice-yearly process in Google Docs — but in practice, fewer than 60% of employees had completed one in the last 12 months. Goals were set in Notion pages nobody revisited. The HR team had no visibility into whether the company's people strategy was actually working.
The situation in plain terms
- Attendance tracked in a shared Google Sheet — manually updated, frequently wrong
- Payroll compiled via email thread — 2 full working days per cycle
- Payslips generated one-by-one in a Word template
- Performance reviews in Google Docs — 40% completion rate
- Goals set in Notion and never reviewed
- No structured 1:1 process — manager-led, inconsistent
- No recognition system — a yearly 'employee of the quarter' email
TimmyHR live in an afternoon. Payroll running in the first week.
GrowthStack's ops manager imported the entire team from a CSV on a Tuesday afternoon. By the time she left the office, all 40 profiles were created, payroll policies were configured, and the first attendance day was already being tracked automatically.
The automatic absent-marking cron immediately solved the Friday-chase problem. Instead of manually checking who'd submitted hours, managers received a notification at end-of-day for any employee who hadn't checked in. The attendance data feeding into payroll was complete, accurate, and required no manual reconciliation.
The first payroll run on TimmyHR took 90 minutes — including the approval workflow. The second took 45 minutes. By month three, payroll was a 30-minute task that the HR lead no longer dreaded.
The Talent Hub transformed how GrowthStack managed performance. Instead of twice-yearly Google Doc reviews, they moved to quarterly OKR cycles with monthly 1:1 check-ins. Goal completion rates went from 45% to 87% within two quarters. For the first time, managers had a structured framework for development conversations — and employees had a clear view of how their work connected to company objectives.
“I used to dread the first week of every month. Now I look forward to it. Payroll takes 90 minutes, attendance is always accurate, and for the first time in two years I can actually tell the board what our people strategy looks like. TimmyHR didn't just save us time — it gave us a real HR function.”

Corespace
Professional Services · 80 employees
Corespace was hiring 3–5 new people every month with an onboarding process that lived entirely in ad-hoc emails. TimmyHR turned new hire onboarding from a scramble into a repeatable system — cutting setup time from a full day to under 30 minutes per hire.
Kente Digital
Digital Marketing · 45 employees
Kente Digital had a retention problem rooted in one thing: employees didn't feel seen. A year after implementing TimmyHR's recognition system, their eNPS jumped 34 points, voluntary turnover dropped 40%, and for the first time their HR team had data to prove the impact of their people strategy.
