About this model
Particle is a full-stack IoT platform combining hardware modules, connectivity, and cloud device management. Enterprises use it to deploy and operate connected products at scale, avoiding the need to assemble separate component, network, and software relationships for every device programme.
The model blends hardware and recurring infrastructure. Device shipments seed the installed base, while connectivity usage and cloud management create ongoing revenue as customers activate more products and expand deployments. Supply, support, and cloud efficiency matter alongside enterprise sales execution.
Model devices shipped, activated devices, connectivity usage, cloud ARR, hardware ASP and margin, expansion, renewals, and churn. Include modules, logistics, connectivity partners, cloud operations, support, and sales costs. Design wins, activation rate, usage per device, gross margin, expansion, and retention should drive scenarios.
A turnkey financial model
Live formulas, no hardcoded values
Outputs are driven by live formulas, so the workbook updates from its assumptions instead of relying on hardcoded results.
All assumptions in one tab
Inputs are clearly marked in the Assumptions tab and separated from calculations, making it clear what to change and what to leave intact.
Statements always balancing
For integrated-statement models, the balance sheet, cash flow, and supporting schedules tie through properly.
Distinct schedules for clarity
Debt, working capital, taxes, and cash flow can get messy quickly. We group calculations in clear schedules, not across disconnected tabs.
No hidden macros or external links
There are no unexplained external workbook links or macros to undermine auditability or portability.
Changes flow through the model
Update a key driver and see the impact carry through the forecast, financing, and return outputs. We never use hardcoded numbers in formulas.

How to build a detailed financial model for Particle
A complete walkthrough of the business, drivers, and assumptions behind the downloadable Particle model - distilled from its pitch deck and publicly available information.
Product & value proposition
Full-stack IoT platform covering three layers:
- Compute: Hardware connectivity modules (e.g. Particle E310) - certified, professional-grade, with built-in radio, microcontroller, power management.
- Connectivity: Particle MVNO (own SIM/data plan management), proprietary communication protocol, bi-directional real-time comms (<100ms latency).
- Cloud: Particle Device Cloud - device management, OTA firmware updates, IoT Rules Engine, REST API, drag-and-drop app builder, data analytics.
Value prop to enterprise customers: "product to market in six months with two engineers"; handles all IoT infrastructure complexity so the customer focuses on their product.
Market
- 74% of IoT initiatives fail (cited: IoT for All, Cisco Connected Futures research) - framing the problem size rather than quoting a TAM dollar figure.
- No TAM/SAM/SOM dollar figures presented in the deck.
- Watsco (key partnership/customer) is described as "the largest distributor of HVAC systems in North America ($4.5Bn revenue in 2018)"; remote diagnostics capability could be "worth hundreds of millions of dollars." - illustrative vertical sizing, not a formal market slide.
Revenue model
Three revenue streams (inferred from product stack; no explicit pricing table in deck):
- Hardware: Sale of connectivity modules (Particle E310 and others) to enterprise customers.
- Connectivity: Recurring MVNO data plan fees per device (SIM management).
- Cloud / SaaS: Recurring platform subscription per device or per fleet (device cloud, device management, OTA updates).
Sales motion: Enterprise direct sales. Time to close improved from 15 months (2017) → 6–7 months (2018) → 4–6 months (2019E).
3CV (Three-Year Contract Value) is the primary bookings metric - reflects up to 3 years of device shipments + 3 years of attached services.
Traction & metrics
- 175,000 engineers building with Particle; 50% use Particle professionally.
- 1 Bn messages delivered to/from devices per month.
- 400,000 firmware compiles in the last 30 days.
- NPS: Particle 61 vs. industry benchmark 41 (average monthly NPS, 2017–Q1 2019).
- IDC Marketscape: Major Player, #1 in customer satisfaction.
- GAAP Revenue: bar chart shows 2017 → 2018 → 2019E growing materially YoY ("doubling YoY"); no axis dollar values visible on chart.
- 3CV Bookings: bar chart shows similar steep growth pattern 2017 → 2018 → 2019E; no axis dollar values labeled.
- Enterprise revenue contribution: 25% (2017) → 70% (2018) → 80% (2019E).
- Kickstarter history (developer era, not operating baseline): 1,601 backers / $125,588 raised (2012 connected lighting); 5,549 backers / $567,968 raised (2013–2015 Spark Core).
- Jacuzzi case study: 6 months concept-to-launch; $2M saved on predictive maintenance; 6% increase in average sales price.
Unit economics
- No explicit CAC, LTV, gross margin, or payback period figures disclosed.
- Implied improvement in sales efficiency: time to close fell from 15 months → 4–6 months over 2017–2019E.
- 3CV metric structure implies multi-year contract commitments with recurring device + service revenue per customer.
Competition / moat
- Largest IoT developer community (comparative claim).
- Full-stack integrated approach (hardware + connectivity + cloud) vs. point solutions - positioned as unique in market.
- IDC Marketscape Major Player designation; highest customer satisfaction scores among participating vendors.
- Developer flywheel: 175,000 professional engineers trained on Particle hardware/APIs become enterprise buyers.
- No competitive matrix slide in deck; no named competitors.
Team & funding ask / use of funds
Recommended financial model
- Archetype + why: Usage-based IoT platform 3-statement model with a device-fleet driver. Revenue has three layers (hardware unit sales, recurring MVNO connectivity per device/month, recurring cloud SaaS per device/month) - this is structurally similar to a hardware + attach-rate model (e.g. Zebra, Sierra Wireless). The 3CV bookings metric and enterprise shift make it bookings-to-revenue waterfall critical. A simple SaaS ARR model would miss the hardware and connectivity revenue streams.
- Forecast horizon & granularity: 5 years (2019–2024), annual with a quarterly bridge for Year 1 (2019). Rationale: enterprise IoT has long sales cycles (4–15 months) and multi-year contracts; monthly granularity adds noise without more data.
- Key drivers & assumptions:
- Avg devices per enterprise deployment: ~500–2,000 devices per customer (HVAC/industrial scale), based on Watsco/Jacuzzi case study type
- Hardware ASP per module: ~$20–$50 per module (market comp for cellular IoT modules)
- Connectivity ARPU per device/month: ~$1–$3/device/month (typical MVNO IoT data plan pricing)
- Cloud SaaS ARPU per device/month: ~$2–$5/device/month (device management + cloud platform)
- Enterprise revenue % of total: 25% (2017) → 70% (2018) → 80% (2019E); reaches 90%+ by 2020 as developer/consumer revenue fades
- Revenue growth rate: described as "doubling YoY" - ~90–100% YoY 2018→2019E; ~60–70% 2020, decelerating to ~30–40% by 2023 as base grows
- 3CV bookings as leading indicator: model 3CV-to-revenue conversion ratio ~0.5–0.6x in Year 1 (hardware ships over time, services ramp)
- Gross margin by stream: hardware ~30–40% (module manufacturing); connectivity ~50–60% (MVNO wholesale vs. retail spread); cloud ~70–80% (SaaS)
- Blended gross margin: ~55–65% at scale as mix shifts toward higher-margin recurring streams
- OpEx: R&D and Sales & Marketing heavy (enterprise IoT requires significant engineering and direct sales); S&M ~35–45% of revenue in 2019 declining to ~25% at maturity
- Developer community: maintained as a cost center / top-of-funnel (no direct revenue in model)
- Scenarios (Base / Bull / Bear - which variables flex):
- Base: ~2x revenue growth 2019, decelerating to ~40% by 2022; blended GM ~60%; S&M efficiency improves with shorter sales cycles
- Bull: Watsco/Jacuzzi partnership scales (Watsco alone is $4.5Bn revenue); enterprise ARPU increases as cloud platform matures; 3+ anchor verticals (HVAC, dental/medical equipment, agriculture)
- Bear: IoT deployment complexity causes customer churn or delayed rollouts (74% failure rate headwind applies to Particle too); hardware commoditization compresses module margins; MVNO data pricing pressure
- Required sheets / outputs:
- Assumptions & Drivers (customer count, devices per customer, ARPU by stream, growth rates)
- Revenue Build (Hardware, Connectivity, Cloud - by customer cohort or aggregate)
- 3CV Bookings Bridge (bookings → revenue conversion)
- Income Statement (GAAP, matching deck metric)
- Simplified Balance Sheet (working capital for hardware inventory; deferred revenue for prepaid SaaS)
- Cash Flow Statement
- Unit Economics summary (CAC, LTV, payback - requires data gap fill)
- Scenario toggle (Base / Bull / Bear)
- KPI dashboard (devices connected, ARPU, enterprise % of revenue, 3CV bookings, NPS)

Created by ex-finance professionals
Hey, I’m Alex and I created Finamodel.
Over my years in the finance industry I kept building the same models over and over again. Same structure, same assumptions, different logo. So I started building frameworks to turn them into clean, reusable templates.
Every model here is one I’d actually use for a client, and I personally vet each one before it goes up.
I’m not an expert in every industry, but I’ve built enough models to know what belongs in one. And when something is completely foreign to me, I reach out to my network for experts to work on our models with us.
Having a template library on hand cuts a first build from hours to minutes.
Need help finding your model? You’ll find me in the Finamodel app!
