Unpopular opinion: Kids do NOT need electric bikes. They need to move their bodies. The point of riding a bike was never to get there faster. The point was to pedal.
To sweat.
To be outside.  To be free To actually use the body they were given. We keep removing every ounce of effort from childhood and then wonder why kids are anxious, weak, restless, and unhealthy. Ride a bike. A real bike.

the best product we built at ramp was the culture - this is the best articulation i've seen yet from krish @krrishd
Today, Ramp raised $750M at a $44B valuation. Last time we grew this fast, we were 1/20th the size. For 2000 years, business was built on two pillars. Today, a third: intelligence. It’s your least governed cost. It’s also your single greatest opportunity.

As I wrote this, I saw X go into meltdown over tokens. You've seen the headlines: “Uber blows yearly AI budget in just one quarter.” “Meta employee burns 281 billion tokens in April.” But, the problem isn't spending. Spending works. Since 2023, the top quartile of our AI spenders doubled their revenue. The bottom quartile? Flat. It's blind spending. We don’t know which spend worked. A sales team has qualified leads. A support team has resolved conversations. These are units you can measure against. All a token tells you is the meter ran, not whether the work was worth it or not. Finance says, “half the budget,” engineering says, “double it” and you don’t know who’s right because there is no shared language of value. There’s no attribution, and no attribution means no allocation. For example, right now, all work, no matter the size or shape, defaults to frontier models. But meeting summaries and calendar updates don’t require GPT-5.5 Pro. In isolation this seems trivial, but re-route just 10% of a $10M AI bill from frontier to GPT-4 level intelligence you’ve saved nearly one million dollars. This sounds like a made-up stat — it’s not. It truly is that much cheaper. This is the future of finance: not blindly rubber-stamping or rejecting AI spend, but allocating it with the same rigor companies apply to headcount.

Three college best friends, @Arushj01, @PranavAPillai, and @vinaykasat_, set out to rebuild systems that felt stuck. Years of collaboration turned into conviction, and from that conviction came @ModusAudit. We’re excited to lead Modus’ $85M Seed & Series A. Modus is rebuilding audit from the inside out. They invest in and partner with audit firms, deploy AI that improves audit quality, create a high-quality customer experience, and translate automation into new business. By rethinking audit at its core, they’re redefining what scale and quality look like in one of the most trust-critical industries. We’re proud to continue backing them on this journey.

Today, Axiom Trust Company is launching publicly with $11.8M in funding led by @lightspeedvp, with participation from @WischoffVC, Runa Capital, SNR, @immad, Primetime Partners, and @thefintechfund. Trust administration is the last undigitized layer of financial infrastructure. The industry still operates on PDFs, email chains, and institutional memory. $2.5 trillion in wealth flows through trusts and estates every year — and that number is only growing. Axiom Trust is the infrastructure layer for the Great Wealth Transfer. Full story in today's @axios article from @ShenLucinda.

Stablecoins used to be considered experimental. That's no longer the case. Big congratulations to Lightspeed-backed @raincards on raising a $250M Series C. In under a year, Co-Founders @rooqster and @cnaut drove a 17x valuation increase, reflecting their execution and growing momentum behind stablecoin-powered payments. With $3B in annualized transactions across 200 partners, this funding will help Rain scale globally, deepen its platform, and invest in new products that redefine how payments work worldwide.
