A new initiative by CreativeGray

We've done it for clients. We're doing it for ourselves. Now we're opening limited slots for early-stage founders.

Overview

Who It's For

Founders who:

  • Have a clear idea or validated need
  • Want to skip the hiring scramble and agency bloat
  • Need a working product that can be demoed, used, or pitched to investors
  • Value speed, technical clarity, and long-term extensibility

What You Get

  • A full-stack, production-grade product — not just a prototype
  • Auth, dashboard, event logging, and analytics support
  • Dev environment + deployment (Vercel/Fly.io or custom)
  • Your core features, beautifully built and delivered
  • A post-build tech walkthrough, pitch demo, and optional next-phase plan
  • An engineering wiki that makes the whole process seamless as the company grows

Why It Works

We start from first principles and move fast because we've done this before. stackin70 products are:

  • Modular: Built to extend — not rewrite
  • Trackable: Events, usage, and growth are baked in
  • Beautifully built: With frontend polish and UX clarity
  • Backed by process: Weekly builds. Clear milestones. One owner.

Process

No more half-baked MVPs. stackin70 delivers fully working, VC-presentable products in 70 days — with a modular codebase, developer-grade infra, and extensibility for v1.1+.

Built for founders, not just demos.

Week 0

Define the Stack

Goal: Clarity before code.

  • We distill your product into core workflows
  • Pick the right tech stack for speed and scale
  • Lock in the first release milestone — and the final Day 70 goal
"We start where most teams get stuck — translating your idea into a technical blueprint that doesn't waste time or capital."

Week 1-7

Build Fast. Ship Smart.

Goal: A working product with real functionality.

  • Frontend, backend, and database built in parallel
  • Authentication, admin dashboard, and core logic live early
  • Weekly demos + deliverables — no black boxes
"You don't get wireframes. You get builds. Every week."

Week 8-11

Polish. Prep. Pitch.

Goal: An investor-ready product with real usage.

  • Finalize frontend styling and UX polish
  • Connect analytics, events, or payment integrations
  • Walkthrough deck, tech stack doc, and launch-ready demo
"You walk away with a product you can pitch, pilot, or raise on."

Frequently Asked Questions

Everything you need to know about stackin70

Our services start at $50K for a complete product and go-to-market execution package.

We deliver a fully working product in 70 days, which is significantly faster than traditional agencies that typically take 6 months and involve multiple vendors.

We work with three main types of clients:

  • Funded Founders (Seed to Series A) who need MVP, brand, and go-to-market execution
  • Corporate Innovation Teams who need fast execution on internal products
  • VCs with Portfolio Support Funds looking to build or rescue portfolio company MVPs

We deliver three key values:

  • Speed
