Market Sizing: SaleHay (B2B Affiliate & CTV Management)

Market Definition

Problem Space: B2B software for managing private affiliate networks/collaborators (CTV), including link tracking, performance analytics, and automated multi-tier payout orchestration.
Geographic Focus: Vietnam (Initial Beachhead), Southeast Asia (SEA Expansion).
Target Segments: SME to Mid-Market brands with high Customer Lifetime Value (LTV) and high Customer Acquisition Cost (CAC) on traditional ad platforms. Key verticals: Healthcare/Clinics, Education, B2B SaaS, Real Estate, and High-ticket Retail.

The total revenue opportunity if SaleHay achieved 100% market share in the target geography.

Top-Down Estimate: The global affiliate marketing platform market is estimated at ~$17B (2023). Southeast Asia (SEA) digital economy accounts for roughly 5-7% of global digital ad spend. Therefore, the SEA TAM for affiliate marketing infrastructure is approx. $850M - $1B.
Bottom-Up Estimate (SaaS only):
- Total registered enterprises in SEA: ~70 Million SMEs.
- Viable digital-first target ORGs (10%): 7 Million.
- High-ticket/Service target ORGs needing advanced CTV platforms (5% of viable): 350,000 ORGs.
- Estimated SaaS ARPU (Average Revenue Per User): $500/year (~1M VND/month).
- SaaS TAM = 350,000 × $500 = $175M ARR.
Bottom-Up Estimate (GMV/Fintech Upside): If SaleHay takes a 0.5% transaction fee on payouts via the platform, and 350,000 ORGs drive an average of $100k GMV/year, the transaction TAM is $175M.
Reconciled TAM: $350M (Combined SaaS + Transaction Model in SEA).

The portion of TAM we can realistically serve with our current product capabilities and regional focus (Vietnam).

Geographic Constraint: Vietnam only for the next 2-3 years.
Targetable ORGs in VN: Vietnam has ~800k registered businesses. Assuming 10% are digitally mature enough (80k), and 20% of those strictly need private affiliate networks = 16,000 ORGs.
SaaS SAM: 16,000 ORGs × $500/year = $8M ARR.
Transaction SAM: 16,000 ORGs × $100k GMV × 0.5% take-rate = $8M.
Total SAM: $16M (Represents ~4.5% of the SEA TAM).

The realistic market share we can capture in the next 1-3 years based on our GTM strategy and resources.

Target Acquisition: Acquire 1,000 active ORGs (approx. 6.25% penetration of the VN SAM) over the next 24-36 months.
SaaS ARR: 1,000 ORGs × $500/year = $500,000 ARR.
Transaction Revenue: Assuming successful platform stickiness and payment gateway integration. 1,000 ORGs × $500k average annual GMV (high-performing ORGs) = $500M GMV.
- 0.5% take-rate on $500M = $2.5M.
Total SOM: $3M Annual Revenue in 1-3 years.

Metric	Current Estimate (SaaS + Take-rate)	2-3 Year Projection (Growth & Upsell)
TAM	$350M (Southeast Asia)	$500M+ (As digital adoption grows)
SAM	$16M (Vietnam only)	$25M (Expanding to Thailand/Indo)
SOM	$3M (1,000 ORGs target)	$5M - $8M (Increasing Take-rate)

Ad-Fatigue & Rising CAC: Facebook and Google Ads costs are skyrocketing while ROAS drops. Brands must transition to performance-based marketing (paying only when a sale is made).
The KOC/Micro-Influencer Boom: The rise of TikTok and social commerce has created millions of micro-influencers (CTV) looking for tools to monetize their audience reliably.
B2B SaaS Maturation in VN: Vietnamese SMEs are increasingly willing to pay monthly SaaS subscriptions for tools that visibly increase revenue (vs. just cost-cutting tools).

Assumption: Brands are willing to pay $40-$50/month purely for the infrastructure (SaaS). Confidence: Medium. We must prove the ROI on the first 10-20 customers.
Assumption: SaleHay can legally and technically integrate as a payment orchestrator to capture the 0.5% transaction take-rate. Confidence: Low-Medium. Requires deep partnership with local Payment Gateways (VietQR, MoMo, Napas). If unable to do so, SOM is restricted to the $500k SaaS ARR.
Assumption: The PLG Viral loop (Affiliate portal bringing in new ORGs) will significantly lower our CAC. Confidence: High. Proven by global benchmarks (like Calendly's 'Powered by Calendly' model).
