We build practical micro‑SaaS
tools that compound.
Spline Solutions is a small product lab shipping focused SaaS tools—then sharing what we learn through selective advisory. We bias for speed, instrumentation, and durable distribution.
Option C: Product-first
We build SaaS tools in the open, learn fast, and occasionally advise when it accelerates real shipping.

Our build thesis
We’re not trying to build everything. We’re trying to build the right small thing—shipped well, distributed early, improved continuously.
Narrow ICP
Start with a specific buyer and a single painful workflow. Generality kills conversion.
Distribution-first
Validate channels before polishing features. Build what a reachable audience already wants.
Instrumentation
Activation, retention, and unit economics. Improve by measurement, not vibes.
The playbook
Principles we apply repeatedly when building micro‑SaaS and applied AI tools.
Validate in days
Landing page + offer + channel test → then code.
Trust early
Audit trails, sane defaults, and cost discipline from v1.
Ship, then iterate
Release small, observe behavior, tighten loops.
Selective advisory
Short engagements, clear deliverables, limited slots.
Sprint10 business days
Venture Sprint
ICP + offer + pricing + channel test + MVP plan.

MVP shipped with onboarding, billing, analytics, and production basics.
