Why Entalogics for SaaS

Four things every SaaS actually needs.

The reasons clients pick us, in their own words. Each one is something most agencies will swear they do — and most don't.

Architecture01

Multi-tenant from line one.

Row-level isolation, per-tenant config, plan-aware feature flags. Never the "we'll refactor when we have customers" anti-pattern.

Speed02

AI-augmented = 2x shipping rate.

Boilerplate, schemas, tests and migrations automated under senior review. Engineers spend their hours on architecture, not autocomplete.

Compliance03

SOC2 / GDPR-ready, day one.

Audit logs, encryption at rest, role-based access, data residency — built in. Not a Q4 retrofit when your first enterprise lead asks.

Ownership04

Code, infra and IP. All yours.

Your AWS account. Your repo. Your decisions. We're a partner, not a hostage situation. Hand-off in a week if you scale internal.

CAPABILITIES

Six SaaS shapes,
one engineering bench.

We've shipped each of these multiple times. The architecture decisions for #1 are not the same as for #4 — and that's the point of hiring us.

PROCESS

From idea to ARR
in four phases.

A SaaS build with us is calendar-time predictable. Same shape every project; only the scope changes.

  • 01

    Discovery & shape

    Week 1

    Senior engineer scopes the product. We map tenant model, plans, pricing, integrations, compliance posture — not a 200-page SOW. By Friday you have a fixed-quote scope.

    • Architecture diagram
    • Fixed-quote scope
    • Risk log
  • 02

    Design & build

    Weeks 2–6

    Product design and engineering run in parallel. Multi-tenant schema, auth, billing, admin and the first three end-user features ship to staging in two-week iterations.

    • Figma → production
    • Staged builds weekly
    • Demo every Friday
  • 03

    Launch

    Weeks 7–10

    Production deploy, monitoring, error budget set. First real customers onboarded with the founder watching the dashboard live. We ship, you sell.

    • Production deploy
    • Observability stack
    • On-call runbook

FAQ

Things every founder asks.

Don't see yours here? Ask us directly.

A multi-tenant SaaS with auth, billing, admin and 3 end-user flows ships in 6–10 weeks. We commit to that in writing in the fixed-quote scope at end of week 1.
Yes. You get full repository access, documented infra-as-code, and a clear assignment of work product. We do not withhold keys, environments, or deliverables after payment milestones.
MVP builds are fixed-quote with milestones. Dedicated teams are priced per senior engineer per month on 30-day terms. Enterprise engagements are scoped for procurement with transparent rate cards.
We architect and ship SOC2-ready and HIPAA-ready patterns (audit logs, RBAC, PHI boundaries) every week. Formal attestation is coordinated with your compliance team and auditors as a scoped workstream.
We run a documented hand-off: access transfer, runbooks, and KT sessions with your team. Most transitions complete in 2–4 weeks. Dedicated engagements cancel with 30 days notice — no hostage-taking.
Yes. Mutual NDAs are standard. We provide MSA and SOW templates that map cleanly to vendor security reviews; your legal team can redline against our baseline.
