Backdoor
Filtered for OPT on Handshake, and still no interviews.
Handshake's OPT and sponsorship filters show what employers chose to report. Backdoor writes to founders of startups that can hire you on OPT, and says you need no sponsorship.

Backdoor
The short answer
If you're on OPT or STEM OPT and want a startup job, pick Backdoor. It writes only to companies that can hire you on your status, tells the founder in one line that you need no sponsorship, and sends from your Gmail after you approve.
When Handshake fits
Handshake suits international students looking for internships, on-campus jobs and employers that recruit through their school.
Backdoor vs Handshake, side by side.
 Backdoor | ||
|---|---|---|
| Who reads it first | The founder or hiring manager at the startup | A recruiter, after your work authorization answers |
| How companies are picked | Startups that fit you and can hire you on OPT or STEM OPT | "Accepts OPT/CPT" and sponsorship tags that employers set themselves |
| What you do | Share your LinkedIn, then reply SEND to the notes you like | Filter, apply to each posting and wait |
| Follow-ups | Three, sent for you in the same thread, stop when they reply | None; you wait for the recruiter |
| When you hear back | 9 in 10 first replies came within two weeks | When a recruiter gets to your application |
| Risk to you | Every email says you need no sponsorship on OPT, and you approve it | Tags are what employers chose to report, not a guarantee either way |
| Where you use it | WhatsApp or iMessage, with a web dashboard | Web app plus iOS and Android apps |
| Price | India: passes from ₹999 for 7 days, nothing renews. US: $1 first week, then $29/month | Free |
| Free plan | Chat, profile research, your resume and a demo search with sample matches are free. You pay for outreach. | Free for students and alumni of partner schools: profile, job search, applications, messages and events. |
| Public rating | New, so no large review base yet | 4.9/5 on App Store (139K reviews) |
Handshake facts checked October 2026. No paid student plan found on 2026-10-18; the App Store lists the app as free. "Handshake Premium" is software Handshake sells to schools' career centers, not a student plan. Employers post for free and pay for more messaging.

A checkbox decides before a person reads you.

Your profile says you'll need sponsorship one day.
- 2
The employer's filter sees that first.
- 3
Your OPT, which needs nothing from them, never comes up.
Why international students switch from Handshake.
For an international student on OPT, the best Handshake alternative for a startup job is Backdoor. Handshake asks whether you will now or in the future need sponsorship, and employers see your answer before your work. Its "Accepts OPT/CPT" and sponsorship filters come from what each employer reports, so a missing tag can hide a company that would hire you, and Amherst's career center calls the filters a starting point, not a guarantee.
On OPT, an employer sponsors nothing: your EAD card is your work permit for 12 months, and the STEM extension adds 24 more. Many founders of small startups don't know that. Backdoor writes only to companies that can hire you on your status, and the first email says so in one plain line, next to why you fit what they're building. It goes from your own Gmail once you reply SEND.
Your unemployment days count while you wait, so speed matters. Across 11,300+ first emails to founders, 9 in 10 people who heard back got their first founder reply within two weeks. Backdoor follows up three times in the same thread, 3, 4 and 5 days apart, and about 3 in 10 replies came after a follow-up.
What Handshake users report.
- In a small Kent State student survey, none of the respondents got a job through Handshake, and an international student said it doesn't serve students limited to on-campus work (March 2025). theburr.com
- A reviewer says few local jobs show up, and the sponsored listings are far away and outside their field (March 2025). apps.apple.com
- Recruiters ignore stated preferences and send repeated, irrelevant messages, one reviewer writes. apps.apple.com
- Handshake AI postings disappear after students sign up, and students want clearer pay and eligibility before they spend time on them (May 2026). themetropolitan.metrostate.edu
- A reviewer says most jobs are limited to US residents and that deleting an account is hard (October 2026). trustpilot.com
Here's what it feels like instead.
Backdoor does the searching, writing and chasing. You stay in the loop and say yes.
BackdoorA founder reads it, not a filter
The founder reads why you fit before any sponsorship question comes up.
BackdoorReach them before the job is posted
Backdoor reaches startups that just raised or launched, before they post anywhere, let alone on Handshake.
BackdoorNothing goes out without your yes
You see the line about your OPT in every email, and nothing goes out until you say SEND.
The note Backdoor would write for you.
Example
Karthik, a master's in computer science on OPT since June, who built a real-time bidding simulator for his capstone.
Why Adlane, why now
Raised a seed round for ad budgets that move themselves between channels.
The person and the startup are made up. Your notes are written from your own work and each startup's news.
Hi Dana,
Congrats on Adlane's seed round. Moving budget between channels by the hour is the problem I spent my master's on.
For my capstone I built a real-time bidding simulator that replays a day of auctions in four minutes, and used it to test pacing rules for a class of 60.
I'm on OPT, so there's nothing to sponsor to hire me.
Could we do a 15-minute call next week?

Startups that fit you, with notes ready to send.
Questions, answered.
They show what each employer chose to report. A missing tag can mean the employer skipped the question, so companies outside the filter may still hire you. Career centers call the filters a starting point.
No. On post-completion OPT your EAD card is your work permit. On STEM OPT the employer uses E-Verify and signs a training plan with you, Form I-983, which is still not visa sponsorship.
Truthfully. If you will need an H-1B later, the honest answer is yes. That's why a short email to a founder works better than a form: you can say what OPT means in one line, next to your work.
Yes. Use Handshake for campus recruiting and internships, and let Backdoor write to founders at startups that can hire you on OPT.
9 in 10 people who heard back got their first founder reply within two weeks of their first email. About 3 in 10 replies came after a follow-up, which Backdoor sends for you.
Profile research, career advice, resume help and a demo search with sample matches are free. Outreach is paid: in the US a $1 first week, then a monthly, quarterly or lifetime plan; on an Indian number, one-time passes in rupees.
