Excited to welcome Archetype and Circle Ventures as strategic investors, with continued support from our long-term backers. The next generation of finance will be programmable. Software, agents, and onchain systems will move value globally at machine speed, and they’ll need infrastructure built for verifiable execution and programmable control. That’s the future we’re building for at Turnkey: scalable, API-first wallets and verifiable computing infrastructure designed for a world of programmable money and agent-driven transactions. Grateful for the continued conviction from Sequoia, Bain Capital Crypto, Lightspeed Faction, Galaxy Ventures, and Variant. Thank you to our customers for the trust you put in us, and a huge shoutout to the Turnkey team for grinding against this vision.
Thrilled to announce a $12.5M strategic investment to meet accelerating demand for crypto wallets and verifiable computing. With participation from @circle_ventures, @archetypevc, and existing investors @BainCapCrypto, @FactionVC, @galaxyhq, @sequoia, and @variantfund.

What does it take to become a CTO? ā€œMost technical leaders are forced to figure out the CTO role on the fly, which often leads to expensive mistakes in hiring and architecture.ā€ Learn more about "Becoming a CTO" from #UCBerkeley Engineering hubs.li/Q045GHgy0 @Cal_Engineer

Early-stage product management isn’t about roadmaps. It’s about learning fast, shipping fast, and staying close to users.

Startups don’t die from one dramatic mistake. They die slowly from losing focus, slowing their learning, and avoiding the hard truths that keep them aligned and moving forward.

Startups rarely die from competition. They die from internal gravity: too many projects, too much noise, not enough truth. Focus is oxygen. techfounderstack.com/p/why-s…

The most valuable engineers today aren’t the best coders. They’re the ones who think in systems, understand users, and ship fast with AI.

AI is turning ā€œI have an ideaā€ into ā€œI built a prototypeā€ in minutes. The real differentiator isn’t execution anymore -> it’s taste, insight, and iteration speed. Link to full article: techfounderstack.com/cp/1797…

AI is dissolving old product development roles. Designers ship. Engineers design. PMs shift to strategy. The future team? A small group of ā€œbuildersā€ using AI as leverage. Speed is the new moat. designplusai.com/cp/17973956…

Direct network effects (Slack, WhatsApp), cross-side marketplace effects (Airbnb, Uber), and data network effects (Google, Figma) all create defensibility. The strongest companies though compound multiple layers. These moats aren’t built, they emerge as users connect.

In a booming market, even a ā€˜good-enough’ product decent team can win. The market does the heavy lifting.

Product-market fit starts with the market. Find the fast-moving water first, then build the boat.

The key isn’t to ban debt. That’s impossible. It’s to make deliberate trade-offs: Is this shortcut necessary to hit a critical milestone? Do we have a plan for when to clean it up?

Great teams don’t fear debt. They manage it. They borrow against the future strategically. They repay when the costs outweigh the benefits.

Every founder faces the same question: ⚔ Should we take the shortcut and ship fast? šŸ› ļø Or slow down and build it right? Here’s what I’ve learned about balancing technical debt with product speed 🧵

But technical debt compounds. Features take longer. Bugs multiply. Engineers avoid touching parts of the code.Suddenly, speed has become fragility.

When you’re early, shortcuts create opportunity. They help you move faster, win customers, and prove the market. Without them, you risk running out of time before you ever launch.

Technical debt is like a loan. šŸ’ø Cheap at first, expensive later. The trick isn’t avoiding it — it’s knowing when to borrow, and when to pay it back. 🧵 A thread on technical debt vs product speed šŸ‘‡

So what do you do? Borrow when speed is existential. Repay when debt blocks growth. Build a culture that treats debt as a strategic lever, not an accident.
