Internships at a16z-Backed Startups
Updated hourly, this list surfaces internships across the a16z portfolio from seed-stage startups through unicorns, spanning software, hardware, design, finance, and operations.
These are internships at companies in Andreessen Horowitz's investment portfolio, not positions at the venture firm itself. The employers span seed-stage teams, growth companies, and mature private businesses across enterprise and consumer software, fintech, healthcare, crypto, hardware, and other markets. Students may work in software or data, product and design, hardware, research, finance, recruiting, customer functions, or operations. Program structure varies widely: a later-stage company may recruit a sizable summer cohort with training and intern events, while an early startup may place one student directly with a founder or small functional team. The latter can provide broad exposure and visible ownership but may have fewer layers of mentorship or established process.
Portfolio membership is context, not a substitute for evaluating the company and role. Review the product, funding and operating stage when described, team size, reporting line, manager availability, project scope, and whether the function is already established. Check the original posting for program dates, enrollment and graduation rules, compensation, equity if any, work authorization, office attendance, and expected hours. Early-stage employers may hire closer to the term or change priorities more quickly than companies with annual programs, so confirm the current opening and assignment before applying. Compare the learning value of broad ownership with the risk of ambiguous scope, and ask how work is reviewed, what resources are available, and what deliverable is realistic within the internship. Look for evidence that an experienced colleague has time to supervise the only intern or junior member of a function.
Portfolio-company internships can be browsed and filtered for free. A free Simplify account provides saved jobs, application tracking, and Copilot form assistance. Separate company-stage assumptions from facts stated by the employer, and revisit the live source throughout the process.

A16z-backed startup internships often skew toward companies that have already raised institutional venture funding, built larger teams, or entered a more competitive growth stage, while YC-backed internships can include much earlier startups that are still finding product-market fit. That does not make one better than the other. YC companies may give interns broader generalist exposure, while a16z-backed companies may offer more mature teams, bigger markets, and stronger operator networks. Students should compare company stage, manager quality, project scope, and hiring velocity rather than choosing only by investor brand.
Some a16z-backed companies become major breakout startups, but investor backing is not a guarantee of success. Andreessen Horowitz has backed well-known companies across software, fintech, AI, healthcare, infrastructure, consumer, and crypto, which can make the portfolio a useful place to discover ambitious startups. Still, portfolio companies can fail, pivot, lay off employees, or stop hiring interns. Treat a16z backing as a signal to investigate further, not as proof that a company is safe. Look for real customers, active hiring, strong leadership, and a role tied to core company priorities.
Many a16z-backed startups pay interns competitively, especially in software engineering, data, product, design, and technical operations roles, but pay varies by company stage, funding, location, team, and internship scope. A late-stage company may pay closer to big-tech cash compensation, while an earlier startup may offer less structure or a smaller package. Do not assume every internship includes housing, relocation, remote flexibility, or equity. Compare compensation with mentorship, project quality, return-offer potential, and whether the role gives you useful startup experience.
The best company size depends on what you want from the internship. Smaller a16z-backed startups may give interns more ownership, faster context, and closer access to founders, but they can have less structure and fewer intern seats. Larger portfolio companies may offer clearer onboarding, more specialized teams, stronger mentorship, and more recognizable resume signal, but the work may be narrower. A good practical target is a company large enough to support an intern well, but still small enough that your project can matter.
Internships at a16z-backed startups are often competitive because many candidates recognize the investor brand and because startup intern classes are usually smaller than big tech programs. The strongest applicants show more than general interest in startups. They can point to projects, prior internships, open-source work, writing, growth experiments, design work, or customer-facing experience that matches the role. A referral can help, but it does not replace fit. The best applications make it obvious why this company and why this team.
A16z backing can reduce some uncertainty, but it does not make a startup safe. Portfolio companies can still miss growth targets, change strategy, freeze hiring, delay offers, or reduce headcount. Before accepting an internship, check whether the company is hiring across multiple teams, whether the role is tied to a core product, whether there is a real manager for interns, and whether customers or revenue look meaningful. VC backing is one useful signal, but students should still evaluate the actual role and team.
Choose an a16z-backed startup over big tech only if the role gives you the learning curve, mentorship, and ownership you want. Big tech usually offers more structure, a clearer internship program, stronger brand safety, and more predictable recruiting timelines. A strong startup internship may give you faster responsibility, closer access to leadership, and a sharper view into company building. The worst choice is not startup versus big tech; it is joining a team with vague work, weak mentorship, or unstable hiring plans.
The strongest approach is to apply early, tailor your resume to the role, and use targeted outreach. Startups are smaller than large public companies, so a thoughtful message to someone on the team can matter. Mention why the company, why the role, and what proof of work you can share, such as a project, portfolio, GitHub repo, writing sample, or growth experiment. Simplify can help you save a16z-backed startup roles, autofill applications, track deadlines, and use networking tools to find people connected to the company.
The best way to find more a16z-backed startup internships is to combine a portfolio-company list with startup filters for role, location, funding stage, company type, and industry. Many students only apply to the most famous companies, which means they miss smaller portfolio companies that may be hiring interns more actively. Simplify can help by letting you filter for startups, save job lists, track applications, and revisit companies as new roles open. Checking regularly matters because startup internship postings can appear and close quickly.
