Two explainers on a Friday — Carta's Series B guide and an LTSE Series A primer — and the live tape this week priced AI rounds like the explainers were never written. This is Startup Fundraising. Today: does Carta's framework actually close the loop we opened Tuesday on the Rule of 40 — or is it still writing for the pre-GPU-cost era? Here's Lucy Hoyle at Carta:
After a post-pandemic period of high valuations and low interest rates, the private market downturn in early 2022 laid the foundations for a more competitive funding landscape. Now, as the venture capital markets in the U.S. and Europe gradually begin to thaw, today’s founders must be prepared to meet a high bar if they stand a chance of securing finance.
Carta dropped its Series B guide today, and the framing's right there in the lede — post-pandemic high valuations gave way to the 2022 downturn, and founders now have to clear a higher bar. Clean story, except this week's AI rounds priced like it was still 2021. Right, so which market am I supposed to prep for? The guide says disciplined, competitive, thawing. The tape this week says sovereign money and fifty-million-dollar seeds. Pick one, because a founder can't pitch both. Run the actual math. If Series A is pricing around eighty million post on three-and-a-half million ARR — the numbers we were working off Tuesday — Carta's Series B framework has to assume a step-up that the dilution can survive. The guide leans on an Octopus Ventures investment manager and Olio's CEO, which is useful, but it reads like a webinar recap. It doesn't give you the margin model. And it defines Series B as institutional VC money — angels are out, priced round only. Great. Clean audience. Doesn't say a word about what counts as gross margin when your biggest line item is GPU inference. Right there is the miss: a 2023 guide writing for fixed-cost SaaS, while the actual Series B pressure point — the Rule of 40 with compute as variable overhead — never gets addressed. The arc this week ran seed to growth stage, and we land on a doc that's one step behind the check. From LTSE:
Series A funding is the next round of financing that startups usually receive after the seed funding stage. At this point, you'll seek larger sums of money to further develop your product or service, expand your team, and grow your customer base. Venture capitalists and angel investors are the usual sources of Series A funding.
LTSE's Series A primer: capital for 'growth and development,' angels and VCs after the seed. Textbook — and I mean that almost literally. 'Growth and development.' After Monday's whole conversation about compute-adjusted margins and data moats, that phrase lands pretty empty. What's 'growth' mean when your single biggest line item is inference? And here's what nobody flags on the page — LTSE runs a long-term stock exchange. They have a very specific institutional stake in how these rounds get structured. The folks teaching you the rules also keep score. Both this and the Carta piece we just hit assume institutional VCs are your natural buyer. This week, banking money and PE were setting the price on AI-native assets at seed. The guide is coaching founders to pitch a class of investor that isn't writing the biggest checks.
