Turnstile raises $29M to modernize AI-first quote-to-cash

Turnstile, a San Francisco-based company, has launched an AI-first quote-to-cash platform for sales-led startups after raising $29 million in a Series A round backed by First Round Capital, OMERS Ventures, Illuminate Financial, and angel investors. The new funding is set to support go-to-market expansion and accelerate product development as the company pushes to make revenue operations faster, cleaner, and less manual for growing B2B SaaS teams.

Why quote-to-cash is breaking for modern SaaS

For years, SaaS billing was relatively straightforward: a simple per-seat model, a predictable invoice, and a clean handoff from “deal closed” to “cash collected.” But the commercial reality for many B2B SaaS companies has changed—pricing and packaging now commonly involve usage-based components, tiers, bundles, pilots, ramps, and mid-cycle upgrades, often with negotiated terms that differ deal by deal.

That complexity doesn’t just live in the sales conversation; it shows up immediately after signature, when teams have to operationalize what was agreed. In many companies, that kickoff moment triggers a familiar scramble—spreadsheets get updated, CRM fields get adjusted manually, and finance teams reconstruct billing schedules from contract PDFs while trying to remember future changes like ramp milestones or year-two pricing shifts. The same deal terms often get entered into multiple systems by different people, which makes it easy for information to drift out of sync across quoting, billing, revenue reporting, and renewals.

When that drift happens, the consequences are costly: invoices can go out incorrectly, finance teams burn time reconciling numbers month after month, and leadership loses confidence in “real-time” metrics that are supposed to guide decisions. The deeper issue is structural—many teams are trying to run increasingly sophisticated commercial terms on workflows that were designed for simpler SaaS. As a result, quote-to-cash becomes less of a smooth workflow and more of a recurring “fix it later” project that pulls time away from growth.

What Turnstile is launching (and who it’s for)

Turnstile positions its product as a quote-to-cash platform built for sales-led startups that want enterprise-grade revenue automation without the traditional complexity and long implementations. The company says legacy quote-to-cash platforms can require 3–6 month implementations, dedicated administrators, and expensive contracts, which can be a mismatch for lean, fast-moving teams. Turnstile’s approach is intended to flip that experience by offering a self-service setup where startups can connect their CRM and generate a first quote in minutes rather than months.

A central idea in Turnstile’s product is turning deal terms into structured data, whether those terms are entered directly or extracted from existing contracts. From there, the platform automates downstream workflows across invoicing, subscription management, revenue recognition, and reporting. The company is led by CEO Jordan Zamir, who has described the product as a “third option” between spreadsheets/disconnected tools and heavyweight enterprise systems, emphasizing speed of setup and flexibility in deal structures.

This kind of product vision lines up with what many operators want right now: keep selling creatively, but stop paying an operational “tax” every time a contract includes ramps, amendments, or custom terms. In practical terms, the promise is that a business can support real-world dealmaking while still keeping billing and reporting accurate and aligned, without relying on manual re-entry and constant reconciliation.

Inside the platform: four modules, one revenue system

Turnstile frames quoting as the earliest breaking point in quote-to-cash, especially in sales-led environments where negotiation is normal and non-standard terms often live in documents as unstructured text. When those terms have to be re-keyed into multiple tools, inconsistencies and human error become almost inevitable, especially as amendments and upgrades happen over time.

To address that, Turnstile describes an integrated platform with four core modules—quoting, subscription management, billing, and financial reporting—designed to manage the full revenue lifecycle in one system. The quoting experience is positioned as drag-and-drop and document-friendly, while still capturing structured data so downstream automation doesn’t break when a deal is custom. Subscription management is built to keep real-time visibility into subscriptions, amendments, and renewals, so changes stay synchronized for both invoicing and reporting.

On the billing side, Turnstile’s platform aims to generate accurate invoices automatically from accepted quotes and subsequent changes, including support for flexible schedules and usage-based billing. For financial reporting, the company says it centralizes subscription and billing data to automate revenue recognition and provide real-time metrics such as ARR, bookings, and AR aging, with drill-down visibility. Put together, the platform is intended to act as a single source of truth for what the customer agreed to, so terms remain consistent as they flow from sales to finance.

An important operational detail is how the system handles change, because subscriptions rarely stay static. Turnstile says when terms change—through mid-cycle amendments, added seats, discounts, or usage adjustments—teams can set an effective date and the platform recalculates invoices and updates reporting automatically. The goal is to reduce manual fixes, prevent mismatched systems, and remove the month-end “reconcile everything” grind that many teams accept as normal.

Funding, investors, and what’s next on the roadmap

Turnstile’s $29 million Series A includes backing from First Round Capital, OMERS Ventures, Illuminate Financial, and angel investors. The company has stated the capital will be used to accelerate the product roadmap and expand go-to-market efforts.

On the product roadmap, Turnstile has pointed to features such as agentic dunning (to automate collections), agentic approvals (to reduce internal bottlenecks that stall deals), and a chat interface that lets teams manage revenue operations conversationally. The company also plans to deepen its ability to ingest existing contracts and convert commercial history into structured data quickly, which is especially relevant for teams migrating from manual workflows and scattered documents.

Early customer momentum is part of the narrative, with Turnstile naming customers including Crafting, Reform, Brellium, Trayd, and atronous.ai. In an example from Crafting, CEO Sumeet Vaidya has emphasized that speed matters when serving fast-moving engineering teams, and that the platform helps remove friction from quoting even when contracts are large and complex. Investor commentary also reinforces the same theme: that quote-to-cash has quietly become a persistent pain point for startups, and that modern pricing complexity—accelerated by AI-driven business models—requires more flexible systems of record.

What this means for RevOps—and why it matters to the AI World community

Viewed through a revenue-operations lens, Turnstile’s launch is a signal that “how you sell” and “how you get paid” can no longer be separated cleanly in modern SaaS. The more creative pricing becomes—usage, bundles, ramps, and negotiated terms—the more fragile spreadsheet-based operations become, and the harder it is to scale without operational drag. Tools that convert deal language into structured data and enforce a single source of truth aim to reduce that drag by ensuring the contract’s intent survives every downstream step.

This is also why the story fits naturally into conversations happening across the ai conferences by ai world ecosystem: founders and operators are increasingly focused on practical, implementable AI that makes teams faster and finance more accurate, not just “AI for AI’s sake.” If you’re tracking this shift as part of the ai world organisation events calendar, it’s the same underlying theme—AI adoption becomes real when it removes repeated manual work and improves decision-quality metrics. At the ai world organisation, funding stories like this are worth watching because they highlight where AI is being applied to core business workflows that directly affect cash flow, forecasting confidence, and the pace at which companies can experiment with pricing.

If your team is building, buying, or modernizing revenue infrastructure this year, it can be helpful to connect these product trends with peer learnings and operator playbooks in the market. The AI World Summit 2026 Asia & Global AI Awards is scheduled for May 28, 2026 in Singapore (Singapore EXPO, 1 Expo Drive), and it’s positioned as a place for creators, founders, agencies, and leaders to share practical strategies and real-world experiences. The broader AI World events schedule also lists near-term gatherings such as the GCC Conclave (March 14, 2026, Hyderabad), Talent, Tech & GCC Summit (April 17, 2026, Delhi), and The Great AI Education Show (April 24, 2026, IIT Delhi, New Delhi).

For readers mapping this to their 2025 and 2026 planning cycles, it’s useful to treat “quote-to-cash” as a strategic capability rather than a back-office afterthought—especially as AI-first companies move faster, iterate pricing more often, and need finance systems that don’t break every time a contract deviates from a template. In that context, Turnstile’s positioning around self-serve setup, structured commercial terms, and automated downstream workflows is a direct response to the operational reality of how modern SaaS deals are actually being sold. And for anyone building in this space, the recurring takeaway is that automation only delivers value when it’s tightly connected to the source of truth—what the customer agreed to—so billing and reporting stay aligned as deals evolve over time.
