SaaS Platform Development in Austin, TX
Austin is a SaaS founder town. The pipeline along MoPac, the venture capital that followed Tesla and Oracle, the East Austin coffee shop full of pre-seed builders — they share one specific problem. They need a SaaS partner who can ship a real production multi-tenant SaaS at a real pre-seed budget, not a $400,000 agency proposal.
The problem with off-the-shelf SaaS scaffolding in Austin
Most Austin pre-seeds get pitched a SaaS-as-a-service platform that locks them in by Series A, or an offshore team that produces a codebase the in-house engineers cannot maintain. Senior-engineering, fixed-scope, full-source-handoff at a real pre-seed budget is rare.
A custom multi-tenant SaaS puts your schema, billing, entitlement, and tenancy under your control. No platform tax. No vendor SDK lock-in. For Austin founders specifically, that means SaaS shaped for founder-grade SaaS MVPs — not a generic template that nearly fits.
What we ship for Austin SaaS founders
MVP-grade multi-tenant SaaS
What investors want to see in week one — clean Postgres schema, real Stripe Billing, real reporting.
Self-serve + sales-assisted hybrid
Product-led growth signals (sign-up, activation, expansion) modeled into the SaaS data layer from day one.
Stripe Billing + usage-based pricing
Plan, seats, usage, dunning, and license state visible on the customer record.
Postgres-native reporting
Founder-readable dashboards on SQL views — no Looker license, no Tableau seat.
Tech stack
Hosted on Vercel, AWS, GCP, or your own infrastructure. PostgreSQL is the source of truth.
Reference builds
J5 Sales OS is our reference SaaS-founder build — a multi-tenant sales operations platform with contact deduplication, outreach presets, dual-mode lead flow, and embedded reporting. We dogfooded the platform on our own sales motion before shipping the pattern. Same architecture works for an Austin pre-seed building a CRM-first SaaS, a Series-A SaaS migrating off a platform, or a bootstrapped founder.
Reference SaaS work: J5 Sales OS, ProtectWithBri, and Wilder Recovery.
How we work remote from Georgia
QUANT LAB USA is founder-led from Macon, Georgia. William Beltz runs every SaaS engagement from kickoff through handoff — no agency middleman, no offshore handoff at the framework boundary. Discovery is a structured video session; weekly demos run on the same cadence; staging is live from week two.
For Austin founders, that means full Eastern-time overlap, fixed-scope contracting against milestones, and on-site work when scope warrants. Book a scope call to walk through your SaaS plan and get a written estimate.
