Niche B2B SaaS: how we partner with industry insiders to ship the first version

How Tsunami Digital partners with industry experts to build niche B2B SaaS products. Our process, deal structures, and what we look for in a partner.

We do not build generic software. We partner with industry insiders - people who know a vertical better than any outsider - to build focused B2B SaaS products that solve real problems for real businesses. This article explains what we look for, how we structure deals, and what the process looks like.

What “niche B2B SaaS” means

Niche B2B SaaS is software built for a specific vertical, sold to businesses, delivered as a subscription. Examples: compliance tracking for financial advisors, job scheduling for HVAC contractors, inventory management for specialty food distributors. Not glamorous Silicon Valley ideas - practical tools that replace spreadsheets, email, and manual workarounds. That is exactly what makes them good businesses.

Why we partner (not just build)

For most projects we deliver and invoice. For niche B2B SaaS, we prefer partnership: shared risk means lower upfront cost for the founder, alignment means we care about long-term success, and a partner who lives with the product makes better architectural decisions than one leaving after launch.

We evaluate four things in a partner:

  1. Domain expertise. 5+ years in the industry. You can explain the problem without using “disruption.”
  2. Access to customers. You can name 10 - 20 businesses that would try it in month one. You have relationships, not a marketing plan.
  3. Willingness to sell. Building is our job. Selling is yours.
  4. Realistic expectations. v1 will not be perfect. PMF takes 3 - 6 months. Revenue starts small.

Our process and deal structures

Phase 1: Discovery (1 week, €2,000 - €5,000). Industry mapping, hypothesis, MVP scope. You get a written brief and detailed estimate regardless of whether we proceed. See Discovery sprint.

Phase 2: Build the MVP (8 - 14 weeks). Full team designs, develops, tests. Weekly check-ins.

Phase 3: Launch and iterate. Initial customers, measure, fix, iterate on real data.

Verticals we find compelling

We are industry-agnostic in principle, but certain verticals stand out: construction and trades (see software for construction companies), logistics, professional services productising methodology (see productizing services), healthcare operations, and hospitality (see software for restaurants).

Frequently Asked Questions

How long from first conversation to live product? Typically 3 - 5 months: 2 - 4 weeks Discovery, 8 - 14 weeks build, 2 weeks launch prep.

What if we disagree on product decisions? You are the domain expert. We are the technical experts. Domain decisions default to you; technical decisions default to us. Established before work begins.

Do you keep working after launch? Yes, either on a monthly retainer for maintenance and iteration, or as part of the ongoing partnership.
