Tools that level the field for the rest of us.
bigSIMPLE is an indie software studio building AI-powered products for independent professionals and small businesses — capabilities once reserved for those who could afford expensive advisors.
A freelancer shouldn't need a lawyer to read an NDA. A mover shouldn't lose jobs to bigger companies with 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.
Four products. Four industries. One mission.
Every Apex product solves one real problem for one real audience. Hover or tap a cell to see what we're building — and where we're heading next.
ApexAcumen
"Understand what you're signing."
AI-powered legal document and insurance policy 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.
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 before the homeowner even starts searching.
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, and no deeper into the ones that don't.
ApexWander
"Stop wondering. Start wandering."
AI-powered local activity discovery for couples and individuals who want spontaneous, personalized suggestions for things to do — without the friction of searching.

Expertise should be accessible.
bigSIMPLE 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.
We build tools we wished existed. Tools that level the field for the people doing the work — not the people advising them.
Built for real people
Independent contractors, gig workers, small landlords, music lovers. Not enterprise IT.
AI as a force multiplier
Large language models deliver insight that previously required expensive professionals — at a fraction of the cost.
Focused & iterative
Tight MVPs, real users, fast loops. No bloat, no feature creep — just products that work.
One stack. Four products.
Every Apex product is built on the same proven foundation — so we move fast, stay consistent, and ship reliable software.
Claude as the engine
Claude (Anthropic) powers our analysis pipelines, behind a clean abstraction so we can swap providers without touching callers.
Strict TypeScript APIs
Node.js + TypeScript in strict mode. Express for routing, Zod for validation, PostgreSQL or MongoDB depending on shape.
Mobile-first PWAs
Ionic + Angular PWAs that compile to native iOS and Android via Capacitor. One codebase covers web, iOS, and Android.
Right tool, right job
PostgreSQL with JSONB for structured data and analysis results. MongoDB for documents. 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 signature-verified.
Built in from day one
JWT auth, bcrypt passwords, MIME-type validation for uploads, parameterized SQL, ownership checks on every query.
Where we're at, right now.
We're a small studio. We tell you exactly where things stand — always.
Building something we should know about? Or just want to say hi?
Whether you want early access to an Apex product, have a partnership idea, or just want to say hello — we'd love to hear from you.
