Best free go-to-market tools for bootstrapped founders

We make InstinctGTM, it has a free plan, and the free plan cannot send. That is the honest starting point for a guide to free tools: every free plan stops somewhere, and the useful question is where. A bootstrapped founder can get a contact database, a CRM, enrichment, scheduling and a writing assistant for nothing, as long as they know each limit before they build on it. Every limit below was read off the vendor’s own page on 3 October 2026.

The short answer

Put together, the free plans cover most of the early work: Apollo.io for a contact database, HubSpot or Attio for a CRM, Clay to try enrichment, Buffer for scheduling, and ours to see what you would write and to whom. What none of them gives you free is sending at any real volume, and that is where you will spend your first money.

A free contact database: Apollo.io, 900 credits per seat a year
A free CRM for a small team: Attio, up to 3 seats on the free plan
Trying enrichment before paying: Clay, unlimited seats, 200 rows a table
Seeing what to write and to whom: InstinctGTM, writes for free and cannot send

What does a bootstrapped founder actually need for free?

Somewhere to find people, somewhere to keep track of the conversations, and a way to be seen. All three are available free, in separate tools, and each is good enough to find out whether a channel works.

What is rarely free is sending. A vendor that lets anybody send cold email at volume for nothing carries the reputation cost of whoever abuses it, so free plans stop at, or just before, sending.

When is it worth paying for a go-to-market tool?

When a free plan has already produced a reply or a customer and the limit is the only thing stopping the next one. Paying before that buys capacity for a channel you have not proven.

Pay for one tool at a time, starting with whichever limit you hit first.

Apollo.io

Best for: A free contact database
Price: Free, then $49/seat
Where the free plan stops: 900 credits per seat a year

Apollo’s free plan carries 900 credits per seat a year against a database of 240M+ contacts and 30M+ accounts, and one connected mailbox per user, per its pages on 3 October 2026. Basic is $49 per seat a month billed annually.

It is the only free plan here that combines finding people with a way to email them.

What it does not do: Nine hundred credits a year is enough to test a list, not to run a channel, and the paid plan is per seat.

Attio

Best for: A free CRM for a small team
Price: Free, then $44/user/mo
Where the free plan stops: Up to 3 seats

Attio has a free plan for up to three seats, with real-time contact syncing and automatic enrichment. Plus is $44 per user a month on monthly billing or $35 billed annually, and Pro, at $99 monthly or $79 annually, adds sequences, per its pricing page on 3 October 2026.

For a founding team of two or three, the free plan is a real CRM rather than a trial.

What it does not do: Sequences start on Pro, so the free plan keeps track of conversations rather than starting them.

HubSpot

Best for: A free CRM you can grow into
Price: Free CRM plan
Where the free plan stops: Paid tiers priced per seat

HubSpot’s pricing page lists a free CRM plan, with paid tiers priced per seat above it, as read on 3 October 2026.

If you expect to add marketing and service tools later, starting in the CRM those tools plug into saves a migration.

What it does not do: Its pricing page showed euros when we read it from Europe, so we have not printed a dollar figure for the paid tiers. Check the price in your own currency before planning on them.

Clay

Best for: Trying enrichment before paying
Price: Free, then $167/mo
Where the free plan stops: 100 Data Credits and 500 Actions a month

Clay’s free plan includes unlimited seats and tables, up to 200 rows a table, and comes with 100 Data Credits and 500 Actions a month, per its pricing page on 3 October 2026. Launch is $167 a month on monthly billing.

It is enough to learn how enrichment waterfalls work on a small list before deciding whether you need them.

What it does not do: The monthly allowance is small, and signal tracking and phone numbers start on Launch.

Buffer

Best for: Free scheduling to the networks you use
Price: Free, then $5/channel
Where the free plan stops: 3 channels, 10 scheduled posts each

Buffer is free for up to three channels, with an AI Assistant on every plan, and Essentials is $5 per channel a month billed yearly, per its pricing page on 3 October 2026.

For a founder posting on two or three networks, the free plan covers it.

What it does not do: The free plan holds 10 scheduled posts per channel at a time, so it suits posting weekly rather than planning a month ahead.

InstinctGTM

Ours

Best for: Seeing what to write and to whom
Price: Free
Where the free plan stops: Writes for every channel; cannot send

InstinctGTM’s free plan covers one venture: content for every channel with a monthly limit, 10 watched companies, and 3 accounts with the dated evidence for why each is worth writing to now. Everything is copy-ready for you to publish or send yourself.

It is the free plan to use when the question is what to say and to whom, rather than how to send it.

What it does not do: It cannot send on the free plan, at all. That boundary is deliberate, and sending starts on Founder at $149 a month.
