How much runway do investors typically expect after a financing round closes?

MedTech investors generally expect a financing to fund 18 to 24 months of runway, enough to reach the next value-creating milestone such as a trial readout, a regulatory clearance, or initial commercial revenue, since raising again before hitting a meaningful milestone typically forces the company to negotiate from a weaker position. A round that funds only 10 to 12 months of runway without a clear near-term inflection point is generally viewed as a red flag by both the board and prospective future investors.

Why should MedTech companies stress-test runway against regulatory and trial delays?

Runway calculated against a static plan can be materially wrong if a clinical trial experiences enrollment delays or the FDA issues a Refuse to Accept letter, an Additional Information request, or an extended review cycle, all of which push out the milestone the runway was meant to fund without necessarily changing the burn rate. Prudent finance teams model runway under a base case and at least one delayed case, since discovering a runway shortfall only after a delay has already occurred leaves far less time to raise a bridge on favorable terms.

How does runway relate to the decision to raise a milestone-tranche or bridge financing?

When remaining runway approaches the time typically needed to close a new round, usually several months given diligence and negotiation timelines, companies often need to decide between raising a full new round, negotiating a bridge such as a convertible note or venture debt, or structuring a milestone tranche that releases pre-committed capital once a specific event occurs. Waiting until runway is critically short removes negotiating leverage, so boards typically track runway explicitly at each meeting and begin fundraising conversations well before the cash reserve is exhausted.

Runway

Months of operating cash a company has before running out.

Reviewed by Christian Espinosa, Founder, Blue Goat CyberLast reviewed May 5, 2026

Definition

Runway is cash on hand divided by net monthly burn. It tells founders and boards how long the company can operate before needing more capital or reaching profitability. Runway projections should use realistic burn forecasts that include planned hires, trials and regulatory fees. Because device programs have long timelines, companies often target 18 to 24 months of runway after each round. When runway falls below about 12 months, many boards start fundraising or cost planning.

What the regulation says

MedTech regulation does not prescribe a minimum financial runway or require companies to hold 18 to 24 months of cash. In the United States, FDA's Quality Management System Regulation, published on February 2, 2024, and effective February 2, 2026, amended 21 CFR Part 820. It requires covered device manufacturers to maintain compliant quality management systems. Runway forecasts should therefore include the personnel, documentation, supplier oversight and corrective action costs needed to meet applicable requirements, alongside clinical studies and submission costs. Financial constraints do not suspend these obligations. Regulation (EU) 2017/745 on medical devices, adopted on April 5, 2017, has generally applied since May 26, 2021. Article 10(9) requires manufacturers to establish and maintain a quality management system; Articles 61 and 83 address clinical evaluation and post-market surveillance. These obligations create costs before and after market entry. Article 10(16) also requires manufacturers to provide sufficient financial coverage for potential product liability, proportionate to device risk class, device type and enterprise size. This is distinct from a prescribed cash runway. Financial planning should account for conformity assessment delays and continuing compliance costs; fundraising triggers remain board and management judgments, not regulatory thresholds.

What this means in practice

MedTech investors typically expect 18–24 months of runway after a round to reach the next value-creating milestone (e.g., trial readout, regulatory clearance). Burning through a round in 12 months without a milestone is a red flag.

Examples

A startup developing a novel diagnostic device calculates its runway to be 15 months, factoring in ongoing R&D, upcoming clinical study costs, and team salaries.
After securing a Series A funding round, a MedTech company aims for 24 months of runway to cover expenses through regulatory submission and initial market launch.
An established firm considers its current cash and projected burn rate, finding it has 10 months of runway, prompting the board to initiate discussions about the next fundraising round or cost-cutting measures.

Common pitfalls

•Confusing gross burn with net burn; revenue-stage companies should track both.
•Not stress-testing runway against trial enrollment delays or FDA RTA letters.

Frequently asked questions

Gross burn is total monthly operating expenses regardless of revenue, while net burn subtracts any revenue the company generates, so a pre-revenue MedTech company in clinical development effectively has gross burn equal to its net burn. Once a company begins generating commercial revenue, tracking both figures separately becomes important because gross burn shows the underlying cost structure while net burn shows the actual cash trajectory, and conflating the two can understate how quickly costs would need to be cut if revenue growth stalled.
