Design System Inspiration of Kraken
1. Visual Theme & Atmosphere
Kraken's website is a clean, trustworthy crypto exchange that uses purple as its commanding brand color. The design operates on white backgrounds with Kraken Purple (#7132f5, #5741d8, #5b1ecf) creating a distinctive, professional crypto identity. The proprietary Kraken-Brand font handles display headings with bold (700) weight and negative tracking, while Kraken-Product (with IBM Plex Sans fallback) serves as the UI workhorse.

- Kraken Purple (
#7132f5) as primary brand with darker variants (#5741d8, #5b1ecf)
- Kraken-Brand (display) + Kraken-Product (UI) dual font system

10. Voice & Tone
Kraken's voice is earned-trust crypto — confident without bombast, technical without alienating, regulator-aware without legalese. Marketing copy emphasizes durability ("Own the Power of Your Money") and the company's track record (founded 2011, has weathered every crypto cycle including FTX collapse). The tone is closer to a brokerage than a casino — feature copy reads like a financial product page, not a meme.
| Context | Tone |
|---|
| CTA | Verb-first. "Sign up", "Try Kraken", "Sign in with Apple" |
| Marketing | Stability + history-emphasized. References to 2011 founding, regulatory milestones |
| Error (verification/security) | Specific + reassuring. "Two-factor authentication required for withdrawals" |
| Educational content | First-class — Kraken Learn academy is part of the brand |
Voice samples
- Tagline: "Own the Power of Your Money — Crypto, Stocks & more"
Forbidden phrases. "Get rich quick", "moon", "to the moon". Casino metaphors. Hyperbolic ROI promises.
11. Brand Narrative
Kraken (legally Payward, Inc.) was founded 2011 in San Francisco by Jesse Powell, Thanh Luu, and Michael Gronager — making it one of the longest-running crypto exchanges still operating (Kraken — Wikipedia, Contrary Research — Kraken). Powell's path to Kraken: in 2001 he founded an internet gaming company helping players manage in-game currencies; 2010 dove into Bitcoin; 2011 consulted for Mt. Gox to help recover from a hack — after observing that exchange's security failures, Powell decided to build a security-first alternative. The platform survived the 2014 Mt. Gox collapse (Powell helped audit the failure), the 2017 ICO crash, 2018 bear market, and the 2022-2023 FTX/Celsius collapses. This survival history is core to the brand voice — Kraken positions itself as the exchange that's "still here" when newer competitors fail. Total funding $867M from RIT Capital Partners, SBI Group, Jane Street, DRW Venture Capital, HSG, Oppenheimer Alternative Investment Management, Tribe Capital, Citadel Securities at ~$20B valuation (Tracxn — Kraken). U.S. IPO filing November 2025 (Payward, Inc.) — earlier 2022/2023 IPO plans were shelved due to regulatory scrutiny + market conditions (Caproasia — Kraken IPO, Forge Global — Kraken upcoming IPO). The 2024 expansion into stocks ("Crypto, Stocks & more" tagline) reflects Kraken's strategy of broadening into a multi-asset retail brokerage, competing with Robinhood for retail trading flow.
12. Principles
- Track record is the proof. UI implication: footer / About pages reference 2011 founding + survived-events list.
- Security before speed. Two-factor auth, withdrawal whitelisting, hardware key support — first-class. UI implication: security settings have main-nav placement.
- Purple is the signal.
#7132f5 for primary; never multi-color brand chrome. UI implication: charts may use semantic colors but UI stays purple-on-white.
- Education = product. Kraken Learn academy treated as core feature. UI implication: "Learn" tab adjacent to "Trade" in main nav.
- Borderless purple buttons signal interactive. UI implication: primary CTAs always purple

13. Personas
Personas are fictional archetypes informed by Kraken user segments (long-term holders, professional traders, institutional clients), not individual people.
Daniel Schmidt, 47, Berlin. Long-term BTC holder since 2014. Uses Kraken Pro for low-fee trading + cold storage withdrawal. Trusts Kraken's regulatory track record above newer EU exchanges.
Aisha Khan, 32, Dubai. Professional crypto trader. Kraken Pro full-time on derivatives. Cares about API uptime + order book depth.
Marcus Davies, 58, London. Recently retired professional. Cautious crypto exposure (5% portfolio). Kraken's "still here since 2011" positioning is the entire reason he chose them.
