50+ Free Tools Used at Real Startups, Organized by Function
If you're interning at an early-stage startup, or about to start one, chances are the tools you'll actually be handed aren't the expensive, big-name platforms you'd assume a "real company" runs on. Most early startups run on a stitched-together stack of free tools, chosen because there's no budget for anything else yet, not because free means lesser. Knowing which free tool actually does which job, before you're handed a login and expected to figure it out, saves you the awkward first week of guessing.
This guide organizes 50+ free tools startups actually use across ten functions: communication, project management, design, marketing, sales and CRM, finance, data and forms, developer tools, productivity and storage, and hiring and general ops. Skim to the category that matches whatever you've just been dropped into, and treat it as a reference to come back to rather than something to read start to finish.If you want to see what startup internships are available at your disposal, check out a list here! And if you’re a bit worried about the suitability of your experience for the role, this blog will help you out!
This guide organizes 50+ free tools startups actually use across ten functions: communication, project management, design, marketing, sales and CRM, finance, data and forms, developer tools, productivity and storage, and hiring and general ops. Startups choose free tools because of budget, not because free means worse, most of these (Slack, Notion, Canva, HubSpot CRM) are the same product a much bigger company uses, just with a smaller free-tier cap. If you're handed a tool with no explanation, checking which function it falls under here usually tells you the job it's doing before anyone explains it. It's useful for any student about to start, or currently doing, a startup internship where the tech stack wasn't explained on day one.
Why do startups need free tools instead of paid ones?
A startup with five people and no revenue yet isn't choosing free tools because free is impressive, it's choosing them because there's no budget for anything else in the first year, and every dollar not spent on software is a dollar that can go toward payroll or product. The free tier of a tool is rarely a lesser version built for hobbyists, it's usually the exact same product a much larger company uses, just with a smaller cap on contacts, storage, or users. Knowing that distinction changes how you should think about the tools you're handed as an intern: they're not placeholders until the "real" software shows up, they usually are the real software.
This is also exactly the environment a program like Ladder Internships places students into. A student working on a real project at an actual startup or nonprofit is using the same lean, free-tool stack the company runs on day to day, not a simulated version built for a classroom, which is part of why the tools themselves are worth knowing before you're handed a login on day one. More on that below.
How do you find the right tool for whatever you've been handed?
To find the right tool, start with how this is organized: each category below groups tools by the specific job they do, communication, project tracking, design, and so on, rather than by brand recognition, since the function is what actually transfers from one startup to the next even when the specific tool name changes. The numbering runs continuously from 1 through 50+ across every category, so the count itself is something you can verify rather than take on faith. Skim to whichever category matches whatever you've just been handed a login for, rather than reading start to finish.
Free tools for communication and team collaboration
These tools replace the hallway conversation and the quick desk-side question that a distributed or lean team doesn't get for free.
Slack: the default group chat for a startup team, organized into channels by project or department, with a free plan generous enough for most early teams.
Zoom: the standard for video calls with people outside the immediate team, still the tool most partners and clients expect a link from.
Google Meet: a lighter-weight video call option built directly into a Google account, useful for a quick internal sync that doesn't need Zoom's extra features.
Discord: originally built for gaming communities, now used by plenty of small startups as an informal, always-on space for quick back-and-forth that doesn't need Slack's structure.
Miro: a shared digital whiteboard for brainstorming, mapping a process, or sketching a plan together when a team isn't in the same room.
Whereby: a no-download video call tool that opens straight in a browser, handy for a quick external call where asking someone to install an app adds friction.
Free tools for project and task management
These tools turn a list of things that need to happen into something a team can actually track together, instead of living in someone's head or a string of messages.
Trello: a simple, visual board of cards moving through columns like "to do," "in progress," and "done," often the first project tool a small team ever adopts.
Asana: a step up from Trello for a team that needs task dependencies, due dates, and multiple views of the same project.
ClickUp: an all-in-one project tool that layers tasks, docs, and goals into a single workspace, popular with startups trying to avoid paying for several separate tools.
Notion: part project tracker, part internal wiki, used to house everything from a task board to onboarding notes in one flexible workspace.
Todoist: a straightforward personal task manager, useful for keeping your own list of what you owe a team, separate from whatever shared tool the team uses.
Toggl Track: a simple time tracker for logging hours against a specific project or client, common at startups that bill by the hour or need to see where time is actually going.
Free tools for design and visual content
These tools cover the actual visuals a startup needs, a slide deck, a social post, a mockup, without hiring a designer for every single one.
Canva: a drag-and-drop design tool for social posts, decks, and one-pagers, the most common starting point for anyone without formal design training.
Figma: the standard tool for actual product and interface design, used by a team building an app or website to mock up screens before any code gets written.
Unsplash: a library of free stock photography, useful whenever a deck or landing page needs a real photo instead of a stock-photo cliché.
Pexels: a second free stock photo and video library, worth checking alongside Unsplash when the first search doesn't turn up the right image.
Google Fonts: a free library of web-ready fonts, used to give a site or document a font that isn't the default and doesn't cost a licensing fee.
Remove.bg: a one-click tool for cutting the background out of a photo, handy for cleaning up a headshot or product image without opening a full editing program.
Coolors: a color palette generator, useful for picking a consistent set of brand colors quickly instead of guessing at hex codes.
Free tools for marketing, social media and outreach
These tools handle getting a message in front of the audience a startup is actually trying to reach, on a budget that doesn't include a media buy.
Buffer: a tool for scheduling social posts across platforms in advance, so a team isn't manually posting in real time every day.
Mailchimp: email newsletter software, still a common starting point for a startup's first email list, though its free plan has gotten considerably smaller in recent years and mainly suits a very small list.
Later: a social scheduling tool built with a heavier focus on visual planning, popular for a team that leans on Instagram or TikTok specifically.
Linktree: a single link that unbundles into several, used to point a social bio at a startup's website, latest post, and sign-up form all at once.
Google Trends: a free way to see how interest in a search term has changed over time, useful for sanity-checking whether a topic or product name is actually gaining traction.
Google Alerts: a simple tool that emails a notification whenever a chosen name or term shows up somewhere new online, an easy way to keep an eye on press mentions or competitors.
Free tools for sales, CRM and scheduling
These tools keep track of who a startup is actually talking to, and make sure a conversation with a lead doesn't just disappear into someone's inbox.
HubSpot CRM: a genuinely free customer relationship management tool for tracking contacts and deals, though the free tier has gotten more limited on contacts and users as HubSpot has built out its paid plans.
Calendly: a scheduling link that lets someone book time directly on a shared calendar, removing the back-and-forth of finding a time that works for both sides.
Google Sheets: not built as a CRM, but genuinely the most common one at very early-stage startups, a shared spreadsheet of leads, stages, and notes that works fine until the list gets too big to manage by hand.
LinkedIn: used less as a social network and more as a research and outreach tool, for finding the right contact at a target company before ever sending an email.
Free tools for finance and operations
These tools cover the money side of a startup, invoicing, basic bookkeeping, tracking who owes what, without hiring an accountant on day one.
Wave: free accounting and invoicing software, still one of the more generous free options for basic bookkeeping, though some advanced features like automatic bank feeds now sit behind a paid tier.
PayPal: used at plenty of small startups simply for sending and receiving an invoice, especially with international clients or contractors.
Zoho Invoice: a free invoicing tool aimed specifically at freelancers and very small teams who don't need full accounting software, just a clean invoice out the door.
Airtable: part spreadsheet, part database, often used to track inventory, vendors, or budget line items in a more structured way than a plain spreadsheet allows.
Free tools for data, forms and analytics
These tools turn a question a startup has about its own product or users into something measurable, instead of a guess.
Google Analytics: the standard tool for tracking traffic to a website, still free and still the first thing most startups install before anything else.
Google Forms: a free form builder used for everything from a customer survey to an internal sign-up sheet, simple enough that almost anyone on a team can build one.
Looker Studio: Google's free dashboard tool, used to turn raw data from Analytics or a spreadsheet into a chart or report someone can actually glance at.
Typeform: a more polished, conversational alternative to Google Forms, popular for a customer-facing survey where the experience of filling it out actually matters.
Hotjar: a tool that shows how visitors actually move through a website, heatmaps and session recordings included, on a free plan meant for a smaller volume of traffic.
Free tools for developer and product work
These tools are where the actual product gets built and shipped, even at a startup with no dedicated engineering team yet.
GitHub: the standard place code actually lives, with version control and a free plan that covers private repositories for a small team.
Vercel: a hosting platform built around deploying a website or web app quickly, with a free tier commonly used for a startup's first live site.
Replit: a browser-based coding environment, useful for a quick prototype or a non-engineer poking at a small script without setting up a local development environment.
Postman: a tool for testing an API directly, used by anyone building or connecting to a backend service to check that requests actually return what they're supposed to.
Netlify: another free hosting option for a website or simple web app, often mentioned alongside Vercel as one of the two most common starting points.
Free tools for productivity, docs and storage
These tools hold the actual files and documents a team is working from, the layer underneath most of the other tools on this list.
Google Drive: shared cloud storage and document editing, the default place most small teams keep everything from a pitch deck to a shared notes doc.
Dropbox: an alternative to Drive for file storage and sharing, still common at startups that started using it before Drive became the default.
Loom: a screen-recording tool for quickly explaining something over video instead of writing it out, though its free plan now caps both the number of recordings and how long each one can run.
Grammarly: a writing assistant that checks grammar and clarity across whatever a person is typing, used constantly for anything client-facing like an email or a proposal.
Free tools for hiring, learning and general ops
These tools cover the parts of running a startup that don't fit neatly into any other category, from finding people to keeping a meeting on the record.
Indeed: still one of the most common places a small startup posts an open role, though the free posting allowance is limited to a small number of listings a month.
Google Calendar: the shared calendar most teams build their actual schedule around, tightly linked to Meet and Gmail.
Zapier: a tool that connects two other tools together so a task happens automatically, like adding a new form submission straight to a spreadsheet, with a free plan generous enough for a handful of simple automations but not much more.
Otter.ai: a meeting transcription tool that turns a call into searchable notes automatically, on a free plan meant for occasional use rather than back-to-back calls all day.
How do you get comfortable with an unfamiliar tool quickly?
Knowing 50+ tools by name is different from being handed three of them on day one and expected to figure out what they're for. The fastest way to get comfortable with an unfamiliar tool is to ask what job it's replacing, a spreadsheet standing in for a CRM, a Slack channel standing in for a hallway conversation, rather than trying to learn every feature at once.
This is also exactly the kind of stack a program like Ladder Internships puts students in the middle of. A student on a real Ladder Internships project is handed the actual free tools a partner startup or nonprofit already runs on, not a simulated version of them, with a dedicated Ladder Coach around to help make sense of an unfamiliar tool quickly instead of guessing alone for a week.
Common questions about free startup tools
1. Does using free tools instead of expensive software look bad on a resume?
No. Most real startups run on exactly this kind of stack, and knowing your way around Slack, Notion, or a free CRM is often more directly useful to a future employer than familiarity with an enterprise tool you'll never touch again as an intern.
2. What if the startup I'm interning at uses a completely different tool than the ones listed here?
That's normal; there are dozens of tools doing the same job in any category on this list. The category, not the specific tool name, is what actually transfers: once you understand what a project management tool or a CRM is supposed to do, picking up a new one takes a day, not a week.
3. Should I learn one of these tools before an internship starts, or wait until I'm told to?
A little familiarity helps, but don't spend more than an hour or two poking around a free account before day one. Most startups would rather you ask a specific question about how they use a tool than assume you already know their exact setup.
4. Is it worth paying for the upgraded version of a free tool if the free plan feels limiting?
As an intern, that's almost never your call to make. If a free plan is genuinely getting in the way of the actual work, that's worth flagging to a manager, not something to solve with a personal credit card.
