Turnstile, developer of a quote-to-cash platform for sales-led startups, this week announced $29 million in funding from First Round, OMERS Ventures, Illuminate Financial, and some angel investors.
When SaaS first emerged, it was built around a simple per-seat model: swipe a card, add users, and pay the bill. But modern SaaS has become far more complex. Today companies sell usage, tiers, bundles, pilots, ramps, and mid-cycle upgrades — with terms often heavily negotiated. Yet the operational infrastructure to manage this complexity hasn’t kept pace.
The cracks appear the moment the deal is signed. The billing spreadsheet gets a new row, the CRM gets a manual update, and the finance team pieces together a billing schedule from the contract PDF—setting calendar reminders to handle the ramp that kicks in at month six or the pricing change in year two.
The same information gets entered into multiple systems by multiple people. Amendments are made mid-contract. Things fall out of sync. Invoices go out wrong. Revenue reporting becomes a monthly reconciliation exercise.
Legacy quote-to-cash platforms require three- to six-month implementations, dedicated administrators, and six-figure contracts. Turnstile describes itself as a “self-service quote-to-cash platform.” Startups can sign up, connect their CRM, and generate their first quote in minutes.
Turnstile uses AI to transform deal terms into structured data—whether entered directly or extracted from existing contracts—and automates everything downstream: invoicing, subscription management, revenue recognition, and reporting.
“Quote-to-cash has been broken for a long time—startups either cobble together spreadsheets and disconnected tools, or they’re forced into enterprise platforms that take months to implement,” said Jordan Zamir, CEO and co-founder of Turnstile. “We built Turnstile to be a third option: enterprise-grade infrastructure that any startup can set up in an afternoon. Structure the deal however the customer needs, and let everything downstream—billing, reporting, renewals—just work. And for companies with existing contracts, our AI can ingest those documents and turn years of commercial history into structured data in minutes.”
The Series A will accelerate Turnstile’s product roadmap and go-to-market expansion. That includes agentic dunning to automate collections, agentic approvals to keep deals moving without bottlenecks, and a chat interface that lets teams manage revenue operations conversationally. Turnstile will also deepen its AI to ingest existing contracts and turn years of commercial history into structured data in minutes.
“Quote-to-cash has been an under-the-radar pain point for startups for several years now. Founders and finance leaders are either managing deals in spreadsheets or buying enterprise software that takes six months to implement. Turnstile is the first platform that’s tailored to how growing companies actually sell, capable of handling complex deals without the complex setup,” said Todd Jackson, partner at First Round Capital.
“AI is accelerating how software is priced and sold, and static revenue systems just can’t keep up,” said Laura Lenz, managing partner at OMERS Ventures. “Turnstile is building the system of record for modern commercial terms, so founders can evolve pricing models over time while keeping revenue infrastructure flexible, durable, and out of the way.”
“Quote-to-cash complexity compounds as companies grow—and AI-driven pricing models are accelerating that complexity even further,” said Alex Gheorghe, investor at Illuminate Financial. “Turnstile brings structure to real-world dealmaking and unlocks automation across billing and reporting, without taking flexibility away from the business.”
