Fig. 03 — services

Full-stack enterprise software, specified to the last detail.

Whatever we build, SpecLoop specifies it first — fully planned, every detail, down to the last line of code. Then built flawlessly with AI. You own the code.

AI applications

LLM features that ship to production — not demos.

Chat interfaces, document understanding, semantic search, autonomous agents, generation pipelines, evaluators. We design AI features against the spec — prompt shape, model choice, fallbacks, cost ceilings, eval criteria — so they work the same way on day 1 and day 100.

Built with

  • OpenAI
  • Anthropic
  • Google Gemini
  • Lovable AI Gateway
  • pgvector / RAG
  • Streaming SSE

Example projects

  • Internal copilots

Internal tools

The ops dashboard your team actually wants to use.

Admin panels, approval flows, CRMs, back-office portals, queue managers, content moderation tools. Built with real auth, real RLS, real audit logs — not a shared spreadsheet. Most internal tools ship within a week.

Built with

  • React + TanStack Start
  • Postgres + RLS
  • Role-based access
  • Audit logs
  • CSV import/export

  • Stripe billing
  • Resend transactional email
  • File uploads (Storage)
  • Per-customer RLS
  • Custom domains

Example projects

SaaS platforms

Multi-tenant SaaS, production-grade — not a prototype.

Sign-up, billing, plans, usage limits, team accounts, admin — the boring stack that lets you focus on the feature you're actually selling. Built on a stack you can scale, not throw away in 6 months. RLS, audit logs, and webhooks are first-class, not bolted on.

Built with

  • Multi-tenant architecture
  • Stripe Checkout + Billing
  • Usage metering
  • Team / org accounts
  • Admin console
  • Webhooks

Example projects

  • Vertical SaaS for a niche
  • AI tool with metered usage
  • Team productivity app
  • Marketplace MVP
  • Embedded analytics SaaS

Fintech & integrations

Payments, ledgers, and the hard APIs — wired into your stack.

Stripe, Fiserv, and others. Reliable retries, idempotency, observability, ledgers that reconcile, and a written contract for each integration — so when something breaks, you know where and why. We mapped a Fiserv boarding API in 3 weeks; a 30-developer team hadn't in 6 months.

Built with

  • Stripe + Stripe Connect
  • Fiserv & banking APIs
  • Webhook verification (HMAC)
  • Idempotent retries + backoff
  • Double-entry ledgers
  • Structured logs

Example projects

  • Payments platform on a daily sync
  • Fiserv boarding API
  • Stripe ↔ accounting sync
  • Custom partner API
  • Webhook router with replay
