$260 billion.
That's how much companies waste on software every year, according to Gartner. Not on software that works. On software that sits unused, delivers no value, or gets purchased through processes so broken that 82% of companies fail to meet their cost-reduction targets—the highest failure rate Deloitte has ever recorded.
When we started building StackMatch, we didn't just assume this was a massive problem. We validated it with the most credible sources in the world: McKinsey, Deloitte, Gartner, Forrester, and the University of Oxford.
Here's what we found.
The Numbers: $49.9B TAM, $7.8B SAM, $78-155M SOM
TAM: $49.9 Billion
The math:
- Global B2B SaaS market: $384 billion (2025)
- Buyer-side procurement costs: 10% of software spend = $38.4B
- Seller-side sales/discovery costs: 3% of revenue = $11.5B
- Total TAM: $49.9 billion
Validation: Gartner confirms 30% of SaaS spend is wasted. McKinsey found 33% of procurement value is lost during planning, with another 20% vanishing during execution. The University of Oxford and McKinsey jointly determined that 70% of technology projects fail. From Nike's $900M ERP disaster to enterprise-wide failures, the pattern is consistent.
SAM: $7.8 Billion (North America Mid-Market)
We're focusing on North America mid-market companies ($10M-$1B revenue) because they have complex procurement needs but lack dedicated teams.
The math:
- North America B2B SaaS: $384B × 42% = $161.3B
- Mid-market segment: $161.3B × 37% = $59.7B
- Procurement + sales/discovery: $59.7B × 13% = $7.8 billion
SOM: $78-155M (Years 3-5)
Conservative targets based on actual competitor performance:
- Year 3: 1% of SAM = $78-82M ARR
- Year 5: 2% of SAM = $155-164M ARR
Competitor Benchmarks Prove It's Achievable
We didn't pull these projections out of thin air. We validated them against real companies:
Vendr (Direct Competitor)
- Founded: 2019
- 2023 Revenue: $62.8 million
- Valuation: $1.0 billion (June 2022)
- Market share: 0.81% of our SAM in just 4 years
Vendr went from zero to $62.8M in approximately 4 years. Our Year 3 target of $78-82M (1% market share) is ambitious but achievable.
G2 (Adjacent Market)
- Estimated revenue: $100-200M
- Founded: 2012
- Validates that B2B software platforms can scale beyond $100M ARR
McKinsey validation: Companies using marketplace strategies grow 10%+ market share annually. 40% of market share winners sell through marketplaces vs. 27% of laggards.
Our targets are conservative by comparison.
Why This Matters Right Now
Three forces create a unique window:
- Record failure rates: Deloitte's 82% procurement failure rate is the highest ever recorded
- Massive quantified waste: Gartner's $260B annual waste figure makes procurement optimization a top-3 CFO priority
- Marketplace momentum: McKinsey found 48% of companies are building or planning marketplace capabilities NOW
The companies that solve this problem first will capture disproportionate market share.
For Investors: The Opportunity in Numbers
Validated Market:
- TAM: $49.9 billion (buyer + seller sides)
- SAM: $7.8 billion (North America mid-market)
- SOM: $78-155M in 3-5 years
Revenue Scenarios:
| Market Share | Annual Recurring Revenue |
|---|---|
| 1% (Year 3) | $78-82 million |
| 2% (Year 5) | $155-164 million |
| 5% (Long-term) | $390-410 million |
Even at 1% market share, StackMatch becomes a $78-82M ARR business. That's Vendr's actual 4-year trajectory, applied to our validated SAM.
At 2% market share, we're looking at $155-164M ARR—a clear path to unicorn status at typical SaaS valuation multiples (10-15x ARR for high-growth B2B platforms).
De-Risked Strategy:
- ✅ Phase 1 delivers standalone value (no marketplace liquidity required)
- ✅ AI-powered workflows = defensible moat
- ✅ 29 category blueprints = near-complete software coverage
- ✅ Clear product-market fit with early users
Validation: This Isn't Speculation
We validated every number with:
✅ McKinsey & Company - Marketplace strategy validation, procurement value loss
✅ Deloitte - Record 82% procurement failure rate
✅ Gartner - $260B annual waste, 60% software buyer regret, 30% toxic spend
✅ Forrester - SaaS market growth and buyer behavior
✅ University of Oxford - 70% technology project failure rate
✅ Competitor financials - Vendr ($62.8M), G2 ($150M) prove feasibility
The problem is massive. The waste is quantified. The solution is clear.
The question isn't whether this market exists. It's who will own it.
