Startup internships: evaluate the work, hours and actual pay

Find a posting that accepts the evidence you have

Kastle's employer-authored Software Engineer Intern posting on YC describes San Francisco work and accepts relevant coursework, personal projects and hackathons as experience. It names evaluations, quality checks and agent development among the tasks. A test harness you built could therefore be more relevant than a generic startup-interest pitch.

The page does not supply a pay amount or deadline. Ask about those terms rather than assuming that an accessible experience requirement also makes the role financially workable. The employer's promises about ownership and feedback are questions to verify in conversation.

Turn improve activation into a finishable assignment

NACE's internship guidance calls for defined work, learning objectives and qualified supervision. Apply that to the project discussion. Improve activation is a goal; it does not tell you what to do on Monday or when the work is finished.

A fictional first project with enough detail to evaluate
Term	Concrete version
Deliverable	Map the setup flow and recommend one change in a two-page memo
Inputs	Approved product access and anonymized support categories
Timing	First draft after two weeks at the agreed weekly hours
Reviewer	The product manager checks the analysis and selects any test
Completion	Memo explains the problem, evidence, alternatives and proposed measure
Blocked inputs	Agree on a revised assignment; do not invent customer findings

Compare cash and time before discussing possible equity

These fictional offers cover 12 weeks. Assume all scheduled hours are worked and the stated cash is paid.

Two startup offers
Term	A	B
Pay	$25 per hour	$4,000 total stipend
Weekly hours	20	30
Total hours	240	360
Gross cash	$6,000	$4,000
Cash per scheduled hour	$25	About $11.11
Review	Named manager; weekly project review	Founder feedback when available
Other benefit	None stated	Equity may be discussed later

What this comparison reveals

B requires 120 more hours and pays $2,000 less. An unspecified future equity discussion is not guaranteed compensation. B might still offer work you value more, but that decision should be made with the cash and time difference visible, not hidden by a startup title.

Ask about a paid need, not permission to do anything

When no suitable internship is posted, connect one piece of your actual work to a task the company appears to need. Keep the initial request narrow enough to answer. Do not volunteer for an undefined trial project before agreeing on the scope and terms.

Startup internship inquiry

Subject: Paid internship inquiry — [function] I am a [student/background] interested in your team's work on [specific task]. In [real project], I produced [output]; the relevant part is [one connection]. Sample: [link]. Are you hiring a paid intern for this work during [dates]? I am available for [hours] in [location]. I would be interested in discussing a defined first project and who would review it.

Separate normal project uncertainty from missing basic terms

A startup may change the project. A manager can respond by defining a replacement assignment. That is different from leaving pay, hours or supervision unresolved. Ask for the written arrangement before accepting, including payment dates and how additional hours would be handled.

Also establish which equipment and expenses the company covers and what work you may discuss afterward. A useful project can be confidential; portfolio permission should not be assumed. Choose with those constraints visible rather than trying to value an unspecified future job or equity grant.

A fixed stipend does not limit the hours

A fictional offer pays $4,000 over 12 weeks. The written offer does not cap weekly hours. Your comparison benchmark is $20 per hour, not a legal wage determination.

The same cash spread across different schedules
Weekly hours	Total hours	Cash per hour
20	240	Calculate
30	360	Calculate
40	480	Calculate

Your turn

Calculate the three hourly equivalents. What total-hour limit would keep the stipend equivalent at or above $20 per hour?

See a worked answer

The equivalents are about $16.67, $11.11 and $8.33 per hour. The guaranteed cash is unchanged, but the time commitment is not.

$4,000 ÷ $20 = 200 total hours. Spread evenly over 12 weeks, that is 16⅔ hours per week. A 20-hour weekly schedule already exceeds that limit.

Request a written hour expectation and how additional hours are handled. Do not assume a fixed stipend or a future equity conversation supplies either an hour cap or additional cash.

For your own application

Compare total cash and total expected hours on separate lines before choosing an offer.
