Weighing a healthtech startup offer? Learn how to assess equity, runway, the hiring process and engineering culture before you sign, with the questions to ask.
The Offer Letter Is the Least Informative Document You’ll Receive
You’ve cleared the final round. The founder calls with an offer. Base salary, equity, a start date and a mission you believe in.
It feels like the decision is about the numbers on the page. It isn’t.
The offer letter tells you what the company is promising. It doesn’t tell you whether the company will exist in three years, whether the equity will ever be worth anything or whether you’ll grow in the role.
For senior engineers, the stakes are high. A wrong move costs more than a bad year. It costs momentum in your career, and often money left on the table.
Healthtech adds extra layers. Regulatory weight, long enterprise sales cycles and funding patterns differ from generic SaaS. A great product with a slow path to revenue faces real risk.
This guide gives you a practical way to evaluate a healthtech startup offer. It covers:
- How to value the equity, and the details most engineers miss
- How to assess runway and funding risk
- What the hiring process tells you about the company
- How to read engineering culture from the outside
- Healthtech-specific questions to ask
- A checklist to use before you sign
Step One: Understand the Equity
Equity often makes up a large part of a startup offer. Most engineers don’t understand it well enough to value it.
Ask for the numbers, not only the percentage
A grant of “0.5%” means little without context. Ask for:
- The number of options
- The total number of fully diluted shares
- The strike price
- The most recent preferred share price and valuation
- The vesting schedule and cliff
Strong founders share these openly. Hesitation is a signal.
Model dilution
Your percentage will shrink with every funding round. Ask the founder how much they expect to raise over the next two rounds. Then model your stake after dilution. A 0.5% stake today might be worth far less as a percentage by the time of an exit.
Check the exercise window
This is the detail most engineers miss, and it matters a lot.
When you leave a startup, you usually have a limited time to buy your vested options. Employees typically have just three months after leaving to decide whether to exercise. Exercising can cost thousands of dollars, depending on the strike price.
Most companies still use the short window. In one quarter, 80% of terminated option grants had a standard 90-day window. Carta’s Peter Walker has been blunt about it: “startup employees should get more than 90 days to exercise their stock options.”
The result is many engineers walk away from equity they earned. Carta found employees exercised just 23% of their vested options in Q4 2023, compared to 31% in Q4 2022.
Ask about the exercise window. A company offering a longer window shows it wants employees to keep what they earn.
Know the tax trade-off
If a company extends the window beyond three months, ISO grants lose their tax advantages and get taxed like non-qualified stock options once exercised after three months. Neither option is wrong. Understand which one you’re getting, and speak to a tax adviser before exercising.
Benchmark the grant
Early hires receive more equity than later ones. Carta data shows the median equity granted to the first engineer at a tech startup was 1.54%, falling to 0.61% after only two more hires. If you’re joining as a senior engineer at Series A or later, expect a smaller percentage, and focus on the value of the grant rather than the percentage alone.
Step Two: Assess Runway and Funding Risk
A great offer from a company with nine months of cash is a risky offer.
Ask directly about runway
- “How many months of runway do you have at current burn?”
- “When do you plan to raise next, and what milestones need to be hit first?”
- “What happens if the next round takes longer than planned?”
These are normal questions. Founders expect them from senior candidates.
Understand the funding timeline
Funding rounds take longer to come than many people expect. Carta found the median time from Series A to Series B in 2025 was 2.7 years. A company needs enough cash and progress to bridge long gaps.
Look at who invested
Strong healthtech investors bring more than money. They bring follow-on capital, enterprise introductions and credibility with health systems. Ask who led each round and whether they plan to invest again.
Check the market position
Healthtech capital concentrates in fewer, larger deals. In H1 2026, 20 mega-deals of $100 million or more took 45% of all capital invested. Some companies raise easily. Others struggle. Find out which group your prospective employer sits in.
Step Three: Read the Hiring Process
The way a company hires tells you how it operates.
Good signs
- Clear communication about stages and timelines
- Interviewers who explain the problem you’d solve
- Questions about how you think, not trivia
- Fast decisions after each stage
- Honest answers to hard questions about runway, churn or setbacks
Warning signs
- Six or more interview rounds with overlapping questions
- Long silences between stages
- Interviewers who disagree about what the role is
- Pressure to accept an offer within 24 hours
- Vague answers about who you’d report to
A slow, disorganised process rarely sits inside a fast, organised company. If decisions take weeks during hiring, expect the same pace once you join.
Step Four: Evaluate the Engineering Culture
You’ll spend most of your time inside the engineering team. Find out what it’s like before you join.
Ask to speak with engineers, not only leaders
Request a conversation with an engineer at your level or one below. Ask:
- “What did you ship in your first month?”
- “How often do priorities change mid-sprint?”
- “How long do code reviews usually take?”
- “Why did the last person in this role leave?”
Look at how they onboard
Ask what your first 30, 60 and 90 days would look like. A clear answer means the company has thought about how you’ll succeed. A vague answer means you’ll work it out alone.
Check the technical decisions
Ask about the architecture, the biggest piece of technical debt and the plan to address it. Engineers who answer openly about debt usually work in healthy teams. Engineers who claim there’s none are either new or not telling you everything.
Understand who leads engineering
Ask about the CTO or VP of Engineering’s background, how long they’ve been there and what they plan to change in the next year. A leadership change soon after you join reshapes your role.
Step Five: Ask the Healthtech-Specific Questions
Healthtech companies face risks generic startups don’t. Ask about them directly.
Regulation and compliance
- “How does HIPAA shape our engineering decisions day to day?”
- “Does any part of the product require FDA clearance, now or in future?”
- “Who owns security and compliance in engineering?”
Customers and revenue
- “Who pays for the product: providers, payers, employers, patients or pharma?”
- “How long is the typical sales cycle?”
- “How many customers are live today, and how many are in pilot?”
Long pilots without conversion to paid contracts are a common healthtech risk. Ask how many pilots have turned into revenue.
Defensibility
AI makes software easier to build. Rock Health has asked the sharpest question about this: “When anyone can build with AI, what holds?”
Ask the founders how they answer it. Strong answers point to proprietary data, deep workflow integration, clinical evidence or hard-won customer relationships. Weak answers point only to features.
Domain learning
Healthtech has a real learning curve. One healthtech recruiting firm notes engineers typically clear the healthtech domain ramp in four to six months, and tend to stay longer afterwards. Ask how the company supports new engineers through this ramp.
Step Six: Weigh the Career Value
Money matters. So does what the role does for your career.
Ask yourself:
- Will I own something meaningful? Ownership of a system, product area or team accelerates growth more than any title.
- Will I learn something new? Healthcare data, interoperability, clinical AI and regulated engineering are scarce, valuable skills.
- Will the work matter? Many engineers move into healthtech because the work affects patients and clinicians. Make sure the role puts you close to the impact.
- Where does this lead? Ask what growth looks like in two years. Staff engineer, engineering manager, head of a team. A clear path signals a company planning ahead.
Your Pre-Signing Checklist
Before you accept, make sure you have answers to these:
- Number of options, total fully diluted shares and strike price
- Most recent valuation and preferred share price
- Vesting schedule, cliff and exercise window
- Current runway and next funding plan
- Lead investors and their plans for follow-on funding
- Paying customers versus pilots
- Your first 90-day priorities
- Your manager’s background and plans
- At least one conversation with an engineer on the team
- How the company handles HIPAA and security in engineering
If any answer is missing or vague, ask again. The way a company responds to direct questions before you join shows how it will treat you after.
Make the Decision With Your Eyes Open
A healthtech startup offer offers more than a salary. It offers ownership, meaningful work and the chance to build skills few engineers have. It also carries real risk.
The engineers who choose well:
- Value equity with real numbers, including dilution and the exercise window
- Ask hard questions about runway and funding
- Read the hiring process as a preview of the company
- Talk to engineers, not only founders
- Test the company’s defensibility in an AI-driven market
Ask the questions. Weigh the answers. Then decide.
