Vertical SaaS has entered a second generation. The first wave automated obvious workflows in large industries. The second wave is going deeper — rebuilding the data layer, the compliance infrastructure, and the network effects that the first generation left untouched.
Construction and field services
- Arjun Mehta (Siteline) — Subcontractor payment infrastructure. $18M ARR, 94% net retention, operating in a market where the incumbents have not shipped a meaningful product update in four years.
- Dana Osei (Fieldpath) — Inspection and compliance workflow for commercial real estate. Recently expanded into the insurance underwriting workflow with the same data.
Healthcare operations
- Simone Park (Celara) — Revenue cycle management for outpatient specialty clinics. The incumbents in this space are legacy systems being displaced by a generation of clinic operators who grew up on modern software.
- Kevin Torres (Lumio Health) — Clinical documentation for behavioral health. TAM is large, regulation is the moat, and Torres has the compliance infrastructure that new entrants will spend 18 months building.
Professional services and legal
- Priya Nair (Clearline) — Matter management for mid-market law firms. NPS of 74 in a category where the average is 22.
- James Adler (Auris) — Contract intelligence for procurement teams. Enterprise deals only, 140% NRR, expanding into the legal ops buyer after establishing procurement.
- Mei Lin (Runway Legal) — Outside counsel management for Series B-D companies. Grew from 40 to 220 customers in 14 months without a sales team.
- Omar Farouk (Stratify) — Regulatory workflow for financial services compliance teams. Operating in a segment where regulatory change has created sustained demand for tooling that incumbents have not addressed.
