What Stack does
Stack is a private, for-profit consumer fintech founded in 2021 and headquartered in Kirkland, United States. The company operates a gamified, mobile-first cryptocurrency investment platform (TryStack.io) targeting Gen-Z users — specifically teenagers aged 13-17 and their parents — a cohort that is systematically excluded from mainstream crypto exchanges and brokerages due to age and KYC restrictions. The product launched publicly on September 8, 2022 and is distributed on both iOS and Android, positioning Stack as a category-defining youth-focused crypto on-ramp rather than a generalized trading app.
The core product is built around safety, supervision, and a simplified asset universe rather than full-spectrum trading. Stack offers a restricted, curated set of cryptocurrencies, blocks off-platform transfers, embeds fraud-prevention safeguards against scams and rug-pulls, and exposes parental-oversight tooling that lets parents monitor and govern their child's account activity. This compliance- and trust-first architecture is the technical and product differentiator versus permissionless wallets and adult-focused exchanges, and it forms the basis for Stack's regulatory positioning in the under-18 financial services space.
The business model is a recurring consumer subscription priced at $3 per month, monetizing through low-friction predictable revenue rather than trading commissions, spreads, or transaction fees. Stack has raised over $3 million in total funding, including a $2.7M seed round announced in September 2022 led by Madrona, with participation from Santa Clara Ventures, The Venture Collective, On Deck, and Madrona Venture Labs. The company is led by founder and CEO Will Rush and operates with a small team of 1-10 employees, consistent with a seed-stage consumer startup.

Stack competitors and assessment
Company assessmentDirect peers
- Greenlight: Greenlight is a leading teen and family fintech offering debit cards, investing, and crypto trading under parental supervision. It is the closest direct competitor to Stack in the youth-finance-plus-parental-oversight category, though with a much broader product suite and significantly more capital.
- Step: Step provides a teen-focused banking and credit-building app with parental oversight features, targeting the same 13-17 demographic as Stack. While Step is primarily banking-led, it shares Stack's positioning around safe, parent-supervised financial products for minors.
- Copper Banking: Copper is a teen banking and financial education platform with parental monitoring. It overlaps with Stack's educational + supervised finance thesis, though Copper focuses on banking/deposits rather than crypto trading.
- Current: Current is a mobile banking platform serving teens, young adults, and families with parental controls and money management features. It competes for the same parent-teen wallet relationship Stack targets, with broader banking functionality.
Broad incumbents
- Robinhood: Robinhood is a major retail investing and crypto platform that has explored youth/teen products (e.g., Robinhood Snacks). While it does not currently offer full teen trading with parental controls, it has the scale, brand, and licensing to enter Stack's niche rapidly.
- Coinbase: Coinbase is the largest US crypto exchange, with educational content (Coinbase Learn) and increasingly consumer-friendly features. Its scale and regulatory positioning make it the most likely incumbent to launch a compliant teen crypto product.
- Acorns: Acorns is a micro-investing platform focused on early-stage investors with educational content and family/legacy plans. It competes with Stack for young, first-time investors seeking education plus hands-on investing, though without crypto focus.
- Block (Cash App): Cash App (by Block) is a mobile payment and Bitcoin trading app widely used by younger demographics. While it does not formally support teens, it sets consumer expectations for simple mobile crypto UX that Stack must compete against.
Regional players
- Bitbuy / Shakepay: Shakepay is a Canadian crypto trading app with a youth-friendly, gamified UX similar in feel to Stack. While not directly competing in the US teen niche, it represents the gamified Gen-Z crypto product category Stack operates in.
- Busha: Busha is an emerging-market crypto trading platform with educational features targeting younger, first-time crypto users. It represents the broader category of consumer crypto platforms with educational components serving Gen Z in their respective geographies.
