The Spark

Shannon Gove and Bennett Merriman launched Event Workforce in 2010 as university students looking to give other students practical work experience in the events and sports industry. By 2015, the company had grown into one of Australia's largest event staffing operations, managing 300+ staff daily at events like the Australian Open. But managing volunteers at scale was a nightmare—everything ran on spreadsheets and email.

Building the First Version

In 2015, with technical co-founder Chris Grant, they built their own internal scheduling and communication platform to solve their own problem. It was a university project initially, approached with classic startup scrappiness: all sweat equity, no hard costs tracked, no outside capital. The realization came quickly—by mid-2015, they signed their first external clients and knew they had something worth commercializing.

Finding the First Customers

Their first dollar came in mid-2015, with a few signed clients by year-end. Word of mouth became their primary growth engine. They never aggressively marketed early on, relying instead on organic demand from the volunteer management space. The platform worked for mega-events (Super Bowl, Dubai World Expo) and smaller charities alike—anyone managing volunteer schedules, screening, and communication.

What Worked (and What Didn't)

For three years (2015-2018), Event Workforce's profitability funded Rostrefi's growth, allowing them to prove product-market fit without external pressure. By 2018-2019, they were hitting $50,000 in monthly SaaS revenue. But scaling required more than bootstrapping could provide. They discovered customer acquisition cost was roughly $3,000-$4,000 per $1,000/month customer—a healthy 3-4 month payback. Google Ads and LinkedIn Ads complemented their sales team, though word of mouth remained dominant. The real challenge: balancing high-touch enterprise deals ($50k-$500k/year for mega-events) with scalable SaaS ($10k-$30k/year for nonprofits and universities). They realized they couldn't ignore the fact that different customer types had fundamentally different needs.

Where They Are Now

By late 2019, Rostrefi had 100-150 SaaS customers generating roughly $100,000 in monthly SaaS revenue (about $1.2M ARR), with year-over-year SaaS growth of roughly 100%. They raised $2 million AUD to accelerate. The team grew from under 10 to 20 people across Melbourne, San Francisco, Colorado, New York, Manchester, London, and Dubai—7 engineers, 2 quota-carrying sales reps, and teams focused on partnerships and customer success. They're pushing SaaS from 40% of total revenue (2018) toward 60%+ (2019+), with ambitions to hit $200,000/month SaaS revenue. Monthly burn sits around $100,000 with 12+ months of runway. Shannon, now 31 and married with a newborn, continues running both Event Workforce and Rostrefi, focused on riding the momentum without chasing the highs and lows too hard.

Why It Worked
  • Solving their own acute pain point at scale (managing 300+ staff daily via spreadsheets) meant they built a product that solved a real, measurable problem rather than an assumed one.
  • Using Event Workforce's profitability to bootstrap Rostrefi for three years eliminated investor pressure and allowed them to validate product-market fit organically before spending heavily on acquisition.
  • Word-of-mouth dominance emerged because their product worked across vastly different customer types (mega-events to small charities), creating natural advocates who referred peers facing identical scheduling and volunteer management challenges.
  • Understanding their unit economics ($3,000-$4,000 CAC for a $1,000/month customer = 3-4 month payback) allowed them to confidently invest in paid channels (Google Ads, LinkedIn Ads) only after proving the model worked organically.
How to Replicate
  • 1.Identify a scalable operational pain point within your own business that affects multiple teams, then build an internal tool to solve it before attempting to commercialize.
  • 2.Bootstrap your SaaS product using cash flow from an existing profitable business for at least 2-3 years to prove product-market fit without external pressure or dilution.
  • 3.Calculate your customer acquisition cost and payback period (CAC ÷ monthly contract value) before scaling paid channels; only invest in Google Ads and LinkedIn Ads once organic word-of-mouth validates a healthy 3-4 month payback.
  • 4.Design your product to serve multiple customer segments (enterprise deals and SMB subscriptions) simultaneously, as this breadth creates more word-of-mouth referral vectors than serving a single narrow segment.
