B2B SaaS investment.

Why B2B SaaS specifically

B2B SaaS at €0.5M–€5M ARR has a recurring failure pattern: product-market fit is real, the company has reached repeatable customer acquisition, but the operating burden of scaling - multi-tenant architecture, enterprise procurement, GTM cadence, finance infrastructure - exceeds what the founding team can execute alongside product roadmap. Capital alone funds the runway. Operator-led growth equity funds the runway and deploys the operating capacity to use it.

Where the bottlenecks show up

• Multi-tenant architecture rebuilds for enterprise scale
• Enterprise procurement readiness - SOC 2, ISO 27001, GDPR data residency
• Pipeline cadence and forecasting hygiene before the founder becomes the bottleneck
• Financial reporting, KPI dashboards, board-ready operating cadence
• Senior engineering hiring against six-to-nine-month European market cycles

What we deploy

• Embedded engineering teams of 2–30 specialists drawn from Gateway Group
• GTM operators owning pipeline cadence, partnership development, and enterprise procurement support
• Governance specialists hardening reporting infrastructure for the next two operating stages

Best fit

€0.5M–€5M ARR with established product-market fit, NRR > 100%, and a 24-month operating thesis where deployed labour is the binding constraint, not capital.

How we read a B2B SaaS opportunity

• Net Revenue Retention (NRR > 105% - institutional-quality at 115%+)
• Rule of 40 trajectory and operating-leverage path
• CAC payback period (12–24 months by segment)
• ARR per FTE (€120K–€180K growth-stage benchmark)
• Gross margin durability over time

Frequently asked questions

What B2B SaaS revenue range does TGC target?

TGC works with B2B SaaS companies typically in the €0.5M–€5M ARR range that have established product-market fit and are ready for the operating-execution work that scaling demands.

What does TGC look for in a B2B SaaS investment?

NRR > 105% (institutional-quality at 115%+), Rule of 40 above 40 with a credible upward trajectory, CAC payback inside 24 months for the segment, ARR per FTE in the €120K–€180K growth-stage band, and a 24-month operating thesis where deployed labour is the binding constraint rather than just capital.

Does TGC invest in vertical SaaS or only horizontal SaaS?

Both. The B2B SaaS sector covers horizontal platforms (HR, finance, operations) where the operating bottleneck is enterprise procurement readiness and multi-tenant scale. Vertical SaaS - healthcare, fintech, industrial, real estate, legaltech, HR-tech - has its own dedicated sector page at /sectors/vertical-saas.

How does TGC differ from a B2B SaaS-focused VC?

A B2B SaaS VC provides capital and network value but rarely embeds delivery teams. TGC pairs minority capital with 8–25 specialists drawn from the Gateway Group operating bench - engineers, GTM operators, governance specialists - for the duration of the engagement under a written operating thesis.
