🤝 SaaS M&A Deals

• Taboola agreed to acquire Dianomi (~$38M; premium finance-vertical ad network, US/UK) – announced on September 18, 2026; the deal expands Taboola's Realize advertising platform deeper into premium finance-vertical inventory, adding Dianomi's network of 600+ finance advertisers including Charles Schwab, Invesco, and Bank of America, with closing expected by year-end pending regulatory and shareholder approval.
  
  
• Infillion acquired Foursquare (undisclosed value; location-intelligence and ad-tech consolidation, US) – announced on September 18, 2026; the acquisition pairs Foursquare's location data (100M+ points of interest, 16B check-ins, 250M device coverage) with Infillion's purchase-data assets, is expected to grow Infillion's revenue and headcount 20-25%, and brings Foursquare's roughly 150 employees into Infillion's 650-person team while the brand continues operating independently.

🧠 Key Takeaways

• Most B2B vendors have no plan for their unprompted advocates – founders should identify customers who organically advocate for them, assign a dedicated non-rotating contact to serve them, and prioritize their success ahead of monetization, since that kind of advocacy can't be bought.
  
  
• Ten things that would have sped the $1M-to-$10M climb – hire senior functional owners earlier instead of doing everything yourself, and keep roughly $1 in reserve per $2 of ARR to invest aggressively in sales specialization, customer marketing, and brand.
