What is Carta?
Carta is pulling fund back-office paperwork in-app, then walking into the deal team's CRM.
The recent run is dominated by one pattern: operations that used to happen over email and PDF are being moved inside Carta. Securities transfer instructions now send and track from the app, investors collect their own securities accounts through a self-service portal, wire account setup is AI-assisted, and spousal consent runs through fillable templates. The quarterly compensation benchmark refresh continues on schedule, and the newest release steps outside fund administration entirely with a CRM Chrome extension for deal teams.
What is FastSpring?
FastSpring shipped a Sessions v2 API for headless checkout — a real opening to Stripe and Paddle's territory.
FastSpring's standout March release is the new Sessions v2 API: a programmatic surface for creating, modifying, and updating checkout sessions before redirecting buyers, with localized payment-options retrieval. Around it, the Order Details page got a full redesign (license-fulfillment management, deactivated-key visibility, consolidated lifecycle panels), and monthly refinement digests track a steady drip of fixes — currency expansion (PEN, PHP, MYR, VND), Pix and UPI on Managed Subscriptions, accessibility tweaks on Stacked/Embedded Checkout. A January advisory flagged a coupon-API breaking change (1,000-item cap on inline codes array, effective Feb 23).
Carta vs FastSpring: editorial side-by-side
Carta
6.3FINANCE
Carta is pulling fund back-office paperwork in-app, then walking into the deal team's CRM.
◆ Current state
The recent run is dominated by one pattern: operations that used to happen over email and PDF are being moved inside Carta. Securities transfer instructions now send and track from the app, investors collect their own securities accounts through a self-service portal, wire account setup is AI-assisted, and spousal consent runs through fillable templates. The quarterly compensation benchmark refresh continues on schedule, and the newest release steps outside fund administration entirely with a CRM Chrome extension for deal teams.
◆ Where it's heading
Carta is widening from the system of record for the cap table into the system that runs the workflows around it — in-kind distributions, wires, KYC, and consents each moved from offline exchanges to tracked in-app state. The through-line is fewer handoffs to email and more self-service by the counterparty, with AI applied to the messiest input first. The CRM extension marks a second front: rather than deepening fund ops, it goes after where deal and investor-relations teams spend their day.
◆ Prediction
The distribution workflow now has account collection, transfer instructions, and status tracking in place, so the plausible next step is closing the loop into execution and confirmation without leaving Carta. On the CRM side, expect the browser capture to connect back to Carta's own entity and cap-table data, which is the only thing that would differentiate it from a general-purpose CRM.
FastSpring
0.0FINANCEE-COMM
FastSpring shipped a Sessions v2 API for headless checkout — a real opening to Stripe and Paddle's territory.
◆ Current state
FastSpring's standout March release is the new Sessions v2 API: a programmatic surface for creating, modifying, and updating checkout sessions before redirecting buyers, with localized payment-options retrieval. Around it, the Order Details page got a full redesign (license-fulfillment management, deactivated-key visibility, consolidated lifecycle panels), and monthly refinement digests track a steady drip of fixes — currency expansion (PEN, PHP, MYR, VND), Pix and UPI on Managed Subscriptions, accessibility tweaks on Stacked/Embedded Checkout. A January advisory flagged a coupon-API breaking change (1,000-item cap on inline codes array, effective Feb 23).
◆ Where it's heading
FastSpring is repositioning from a hosted-checkout-and-merchant-of-record vendor toward a more API-driven platform that can compete on the headless ergonomics that have made Stripe, Paddle, and Lemon Squeezy attractive to developer-led SaaS. The Sessions v2 API is the structural piece; the localization expansions and payment-method coverage (Pix, UPI, NOK PayPal, etc.) signal continued investment in non-US international payments where FastSpring has historically out-localized US-based competitors.
◆ Prediction
Expect Sessions v2 to be followed by deeper webhook-based session lifecycle events and an Embedded Checkout SDK rebuilt on top of v2. The localization push should keep widening — likely adding more Latin American and Southeast Asian payment methods to match where SaaS revenue is growing fastest.
