Unclear burn rate and runway figures can leave investors questioning how your startup uses its cash.
Investor updates show how you’re using resources to pursue long-term returns.
When you fail to share complete, accurate numbers, it could seem like you’re simply not looking at them and, as a result, not making informed business decisions. If you can’t explain the numbers, that may imply a lack of intention behind your spending.
Clear context around your investor update metrics can help build long-term investor confidence.
TLDR:
Record funding totals do not mean capital is spread evenly. The Q3 2026 PitchBook-NVCA Venture Monitor, published October 7, reports $515.8 billion in US venture deal value through Q3, roughly 44% above the previous full-year record set in 2021. AI captured 82.7% of that deal value. For your investor update, focus on your startup's burn rate, runway and progress against milestones, not the headline funding total.
Before sending an investor update, check that the numbers cover the same reporting period and explain any unusual spending or financing inflows. Keep the supporting records ready for follow-up questions. Treat current figures as inputs for review, not proof that the books are audit-ready or that a funding round will close faster.

The comparison period changes the story. Crunchbase's Q3 2026 funding report, using data as of October 2, puts global venture funding at $159 billion: down 25% from Q2 but up 53% from a year earlier. Apply that same care to your startup's update: label comparisons clearly and keep metric definitions consistent.
For an update sent in late October, separate completed Q3 results from October figures that are still provisional. Show current runway using cash already available, and keep a potential raise separate from that calculation. As you plan for 2027, name the next milestone your cash can fund and explain how planned hiring or annual software payments will affect burn.
Use labels like these in your update: Q3 actuals (July through September): “Net burn was [confirmed amount], and cash on hand at September 30 was [confirmed balance].” October to date (provisional): “Figures through [cutoff date] are pending review.” Q4 projection (October through December): “We expect net burn of [projected amount], assuming planned hires start in November and annual software renewals are paid in December. This projection excludes any potential raise.” Keep the full-quarter projection separate from actual results, and explain changes to its assumptions in your next update.
Puzzle is an AI-native accounting firm combining accounting software with optional bookkeeping services. You can run your own books or add Expert Reviewed or Full Service bookkeeping. Puzzle accountants or vetted partner firms work in the same ledger, with human review before the books are final.
Pair your financial statements with startup metrics such as burn rate and runway. These metrics are not all line items in a single financial statement. Puzzle's burn and runway documentation describes separate metric cards and a Cash Activity Report for understanding cash use.
Puzzle helps you prepare investor updates with:
Puzzle provides real-time financial reporting with supporting accounting records to review before sharing metrics with investors.
This can help you explain your financial statements and prepare for investor follow-up questions.

Let’s assume you need to calculate your bank burn.
Keep bank burn, net burn and operating income separate in your update. Puzzle's burn guide distinguishes bank balance changes from net operating cash use; operating income belongs to the income statement.
| Metric | What it measures | What it excludes | Best for |
|---|---|---|---|
| Bank burn | Decline in bank balances over a period | No adjustment for financing inflows that can mask cash use | A bank balance snapshot; see Puzzle's burn definitions |
| Net burn | Operating cash outflows less operating cash inflows | Non-operating financing activity, such as new equity and debt proceeds | Tracking cash consumption and runway; see Puzzle's net burn definition |
| Operating income | Revenue less cost of revenue and operating expenses for the period | Non-operating items; under accrual accounting, the unused portion of a prepayment stays an asset | Understanding operating profitability; see income statement basics |
Show the reporting period, accounting basis and any adjustments alongside each metric. Bank burn and net burn explain cash use; operating income explains operating profit or loss. Keeping them separate gives investors a clearer picture of your startup's finances.
Consider accrual reporting when investors request accrual financial statements or when annual subscriptions, unpaid invoices and prepaid expenses make cash-basis results a poor guide to monthly performance. Funding alone does not set a universal switch date. Agree with your accountant on when to start accrual reporting and which prior periods to restate: for example, start next fiscal quarter and restate the prior quarter's monthly figures on an accrual basis. Explain the change in your investor update so comparisons remain clear.
Puzzle maintains cash and accrual books simultaneously, so you can track cash use and runway alongside accrual profit or loss. Its accounting software automates schedules for deferred revenue, prepaid expenses and depreciation, with human review before the books are final. Automated revenue recognition is Stripe-centric; non-Stripe billing requires manual journal entries. Have your accountant check opening balances and schedules before sharing the new accrual figures with investors.
Focus on completed Q3 results, current burn rate and runway based on cash already available, and the next milestone your cash can fund. Keep any potential fundraising separate from your runway calculation, and label all comparisons clearly so investors see exactly which period you're reporting on.
Report both, and keep them separate. Bank burn shows the change in your bank balance over a period, while net burn measures operating cash outflows less operating cash inflows, excluding new equity and debt proceeds. Showing only bank burn can mask real cash consumption if a financing round recently hit your account.
A bank balance can hold steady while your startup consumes operating cash if new debt or equity proceeds offset that use, yet financing inflows are not revenue. Show investors your net burn figure alongside the bank balance and disclose any financing activity separately so they see the actual operating cash picture.
Yes. Puzzle updates cash position, P&L, and balance sheet daily, and tracks burn rate, runway, ARR, and MRR. Check each metric's reporting period before sharing it: the monthly burn run rate uses the most recent full month. Review the supporting accounting records when preparing answers to investor follow-up questions.
Net burn tracks cash leaving your business from operations; operating income measures revenue less cost of revenue and operating expenses under accrual accounting. A large prepayment like an annual AWS bill reduces cash immediately but only flows through operating income as the service is used, so the two numbers can diverge by a wide margin in the same reporting period.
Puzzle's AI Chat answers questions using your actual books and can generate custom reports, such as a P&L for a requested period. You can save prompts to reuse for later investor updates. Check the reporting period, accounting basis and underlying records before sharing the results with investors.
AI Chat is read-only: it cannot independently split transactions, categorize expenses or change your books. AI Cowork is a separate tool that prepares accounting work from your instructions for review; proposed changes need your approval. Transaction categorization and Stripe-centric revenue recognition also run through Puzzle's accounting automation, not through autonomous chat actions. Humans review before the books are final.
