Questions & Answers

As answered by people managing Martian Alpha and StackMail.

What makes your product unique?

Martian Alpha's answer

Martian Alpha is built only for the space economy. Instead of a general stock terminal with a space filter, it puts the things that actually move space stocks next to the market data: rocket launches, US government contract awards, SEC filings (Form D, S-1, Form 4), satellite constellation progress and launch reliability. A free launch calendar, catalyst feed, CANSLIM screener, contract award tracker and private space company directory sit in one terminal, and most of the core tools are free.

Why should a person choose your product over its competitors?

Martian Alpha's answer

General finance sites treat space companies like any other ticker, and space news sites don't connect events to stocks. Martian Alpha does both: when a launch slips, a contract is awarded or an insider files a Form 4, you see it beside the companies it affects. The free plan covers the essentials (launch calendar, catalyst feed, screener, contract awards, watchlist alerts), paid plans start at $5/month, and the data comes from primary sources such as SEC EDGAR, government contract records and launch data, with links back so you can verify it yourself.

What's the story behind your product?

Martian Alpha's answer

Martian Alpha was built by Nethan Nerella, a developer who invests in and follows the space industry. Keeping up with space stocks meant juggling launch trackers, SEC EDGAR, government contract databases, news sites and a brokerage app, and nothing tied them together. Martian Alpha started as a way to put all of that in one terminal and grew into a full research platform covering 70+ listed space companies and the private companies behind them.

Which are the primary technologies used for building your product?

Martian Alpha's answer

React, Vite, Tailwind CSS, Radix UI, TanStack Query, Recharts, Three.js, Node.js, Express, TypeScript, SQLite, Anthropic Claude and Google Gemini (AI research features). Data comes from SEC EDGAR, Launch Library 2 and US government contract data, and the site runs behind Cloudflare.

How would you describe the primary audience of your product?

Martian Alpha's answer

Retail investors who hold or follow space stocks (launch providers, satellite operators, defense-space and space infrastructure), plus analysts, traders and financial advisors who cover the sector. It also serves founders, VCs and aerospace professionals who track private space company funding, government contracts and industry pipelines.

Who are some of the biggest customers of your product?

Martian Alpha's answer

  • Individual space-stock investors
  • Independent analysts and traders covering the space sector
  • Space and aerospace startup founders
