Sectors / Vertical SaaS
Vertical SaaS investment.
Software products built for a single industry vertical - where the moat is regulatory complexity, deep workflow integration, and decade-long category durability. TGC works with vertical SaaS founders compounding through architectural depth and category specialism, not headcount.
Why vertical SaaS
Vertical SaaS is structurally different from horizontal B2B SaaS. The total addressable market is narrower but the competitive moat is deeper: regulatory expertise, vertical-specific workflows, and 10+ year customer relationships once installed. Vertical SaaS at scale routinely posts NRR > 115%, gross margins > 80%, and customer lifetimes measured in decades. The challenge is rarely demand discovery; it is operating capacity to handle vertical-specific compliance, multi-tenant architecture, and enterprise procurement under industry-specific scrutiny. Operator-led growth equity addresses these through architecturally informed engineering deployment, not just capital.
Where the bottlenecks show up
- Vertical-specific compliance - HIPAA, FedRAMP, FCA/MAS/ESMA, IEC 62443, SOC 2 Type 2, PCI-DSS
- Multi-tenant architecture for industries where data residency is non-negotiable
- Industry-specific integration into customer ERPs, EHRs, core banking, MES, and identity systems
- Enterprise procurement readiness for regulated industry buyers (RFP, security review, vendor onboarding)
- Vertical-domain hiring - engineers and GTM operators who understand the customer's operating reality
What we deploy
- Compliance-readiness teams familiar with vertical-specific regulatory frameworks
- Architecture review with senior engineers experienced in regulated multi-tenant platforms
- GTM operators with vertical-domain credibility for enterprise procurement cycles
- Integration engineers for industry-specific connectors (HL7/FHIR, SWIFT/ISO 20022, MES, OPC-UA)
Best fit
Vertical SaaS founders at €1M–€5M ARR with established product-market fit in a single industry vertical (healthcare, fintech, industrial, real estate, legaltech, HR-tech, vertical-specific compliance), NRR > 105%, and a 24-month operating thesis where vertical-domain operating capacity is the binding constraint.
How we read a vertical SaaS opportunity
- Net Revenue Retention by vertical cohort (institutional > 115%)
- Customer concentration and procurement cycle length
- Regulatory compliance maturity (audited frameworks vs aspirational)
- Architectural fit for industry-specific data residency and integration depth
- Vertical-domain expertise across the engineering and GTM teams
Frequently asked questions
- What is vertical SaaS?
- Vertical SaaS is software built for a single industry vertical - healthcare, fintech, industrial, real estate, legaltech, HR-tech - where the moat is regulatory complexity, deep workflow integration, and decade-long customer relationships once installed. Vertical SaaS at scale routinely posts NRR > 115%, gross margins > 80%, and customer lifetimes measured in decades.
- What vertical-SaaS sectors does TGC cover?
- Healthcare-tech (HIPAA, FHIR), fintech (FCA/MAS/ESMA, PCI-DSS), industrial software (IEC 62443, MES, OPC-UA), real-estate-tech, legaltech, and HR-tech. The investment thesis hinges on depth of vertical-domain operating capacity rather than horizontal SaaS scale-out playbooks.
- How is vertical-SaaS investment different from horizontal B2B SaaS?
- TAM is narrower but the moat is deeper. Vertical compliance (audited certifications, not aspirational) and industry-specific integrations (EHR, core banking, MES) are the binding constraints, not pure go-to-market scaling. TGC deploys engineers and GTM operators with vertical-domain credibility instead of generic SaaS playbook executors.
- Who are the leading vertical SaaS investors in Europe?
- Vertical SaaS draws from a mix of horizontal-SaaS investors (Insight Partners, Hg, Bregal Milestone) and vertical-specialists (Five Elms Capital in healthcare, FinTech Collective in fintech, etc.). TGC differentiates by combining minority structure with embedded vertical-domain operating capacity rather than capital alone or control-equity buy-and-build.
- What is the revenue range TGC targets for vertical SaaS?
- Vertical SaaS founders at €1M–€5M ARR with established product-market fit in a single vertical, NRR > 105%, and a 24-month operating thesis where vertical-domain operating capacity is the binding constraint. Below €1M ARR is typically too early; above €5M ARR is later-stage growth equity territory.
- Does TGC support compliance certifications like HIPAA and SOC 2?
- Yes. The embedded engineering team includes compliance-readiness specialists who run SOC 2 Type 2, ISO 27001, GDPR data-residency, and vertical-specific frameworks (HIPAA, FedRAMP, PCI-DSS) as defined work-streams under the operating thesis.
