What we build

The Apex Product Family

Three products. Three industries. One mission: put professional-grade tools in the hands of the people who need them most.

Apex Family Legal AI

ApexAcumen

"Understand what you're signing."

AI-powered legal document analysis for freelancers, contractors, and small business owners who regularly sign contracts but can't afford legal counsel. Clause-level risk scoring — not just summaries.

  • Upload PDF or DOCX contracts
  • Clause-by-clause risk scoring (1–10)
  • Plain-English explanations & recommendations
  • Terms of Service & privacy policy scanner
  • Freelance, NDA, lease & employment support

ApexLeads

"Warm leads before your competitors know."

An AI agent platform that monitors public data sources for intent signals and delivers pre-enriched, scored leads to independent trade contractors — movers, plumbers, roofers, HVAC — before the homeowner even starts searching.

  • Real estate & permit data signal detection
  • Claude AI lead enrichment & urgency scoring
  • SMS & email delivery via Twilio & SendGrid
  • Geography & trade-type targeting
  • Exclusive lead claims — not shared with competitors

Apex Family Music

ApexDepths

"Explore music on your own terms."

A music curation app where you build depth profiles — curated collections of genres and artists each assigned a personal depth score (0–100). Go as deep as you want into the catalogs that matter to you, and no deeper into the ones that don't.

  • Named depth profiles for different moods
  • Per-artist & per-genre depth scores (0–100)
  • Smart catalog exploration via MusicBrainz
  • Taste depth — not just access
  • iOS & Android via Ionic + Capacitor

Who we are

We believe expertise
should be accessible

bigSIMPLE Development is an indie software studio building the Apex product family — a suite of AI-powered tools designed for people who've been priced out of professional advice.

A freelancer shouldn't need a lawyer to understand an NDA. A mover shouldn't lose jobs to bigger companies with dedicated sales teams. A music fan shouldn't need an algorithm to tell them what to love.

We build focused, well-crafted products that solve one real problem each — and solve it thoroughly.

Built for real people

Our users are independent contractors, gig workers, small landlords, and music lovers — not enterprise IT departments.

AI as a force multiplier

We use large language models to deliver insight that previously required expensive professionals — at a fraction of the cost.

Focused & iterative

We launch focused MVPs, validate with real users, and iterate fast. No bloat, no feature creep — just tight products that work.

How we build

Our technology foundation

Every Apex product is built on the same proven stack — so we can move fast, maintain consistency, and ship reliable software.

AI & LLMs

Claude (Anthropic) and GPT-4o (OpenAI) power our analysis pipelines, with a clean abstraction layer to swap providers without touching callers.

Claude SonnetGPT-4oBullMQ

Backend APIs

Node.js + TypeScript in strict mode. Express for routing, Zod for validation, PostgreSQL or MongoDB for persistence — depending on the data model.

Node.jsTypeScriptExpressZod

Mobile-First Frontend

Ionic + Angular PWAs that compile to native iOS and Android via Capacitor. One codebase covers web, iOS, and Android.

Databases

PostgreSQL with JSONB for structured data and flexible analysis results. MongoDB for document-oriented domains. Redis for job queues via BullMQ.

Billing & Delivery

Stripe for subscriptions and per-action fees. Twilio for SMS, SendGrid and Resend for transactional email. Webhooks handled with signature verification.

Security First

JWT auth, bcrypt passwords, MIME-type validation for uploads, parameterized SQL, document-ownership checks on every query — built in from day one.
