Where to find customers who are startup CTOs

Startup CTOs are easiest to sell when a board slide, a security questionnaire, or a vendor sprawl is the villain — not when they are posting a hiring tweet. They compare build-versus-buy, argue about SOC 2 evidence, and ask which stack they can still explain to a Series A investor after three years of 'temporary' tools. If you sell infrastructure, identity, observability, billing, or anything that becomes a line on a cap table conversation, find them in r/startups, CTO Craft, HN, LinkedIn, and G2 reviews written by CTO or VP Engineering titles. Ignore 'how do I become a CTO' posts. Hunt comments that name a questionnaire that paused a deal, a Datadog-plus-five-other-tools invoice, or a build-versus-buy they already regret. That is switching intent with executive budget, not a staff engineer collecting titles.

Where startup CTOs actually hang out

These are the rooms where startup CTOs ask for recommendations, compare tools, and name the competitor they want to leave. Start here before you buy ads.

Redditlarge, mixed quality
r/startups
Technical founders and first-time CTOs post here when a vendor or a process just became existential. Threads titled 'enterprise buyer sent a 400-row security spreadsheet' or 'our AWS plus observability bill is now the runway conversation' are buying notes. Filter for people who mention a team size, a round, or a named incumbent. The comments that compare vendors in complete sentences are the ones worth a reply.
Rules gotcha: The subreddit is full of idea-stage spam and 'feedback on my startup' ads. Skip those. Disclose if you sell in the category. Never pitch in a hiring or fundraising-advice thread.
Slackpaid, senior tech leaders
CTO Craft Community
CTO Craft is built for people who already lead engineering. Conversations about vendor consolidation, hiring a VP, passing SOC 2 without pausing the roadmap, and which observability stack survived a Series B happen with less Reddit theater. If your ACV assumes a CTO signature and a security review, this room's problems match. Public talks and newsletters are the free layer; the Slack is where the buying happens.
Rules gotcha: Recruiters and service providers are not welcome as hunters. Vendors who join only to pitch get a reputation that travels. Contribute a postmortem or a hiring playbook before a product mention.
Hacker Newsvery large, technical executives lurk
Hacker News Ask HN and infrastructure threads
Startup CTOs still treat HN as the place to ask whether a SOC 2 consultant is a scam, whether to build billing, and which cloud bill just became a board topic. The gold is not Show HN. It is the comment on an AWS, Okta, or observability thread where a CTO names consolidation, a failed enterprise review, or a tool they will rip out after the round. 'Ask HN: what would you not outsource at 25 engineers?' is a buying committee.
Rules gotcha: Anything that reads like marketing gets flagged. No tracking links. Answer the architecture or risk question in the comment itself. Do not hijack a launch with a competitor pitch.
LinkedInslower, board-adjacent
CTO and VP Engineering operator posts
Once a CTO is selling to mid-market, they spend more time on LinkedIn than Reddit. Posts about vendor sprawl, 'we failed the security review,' or consolidating five monitoring tools collect comments from other CTOs who will forward a useful reply to finance. A comment that names SSO, audit logs, or a migration off a tool the last VP bought can become an internal thread. This is also where your champion's CEO lurks.
Rules gotcha: Skip thought-leadership carousels. Reply under posts that include a headcount, a round, or a named vendor. Do not pitch in a 'we are hiring' post.
Reviewsdecision-stage
G2 reviews by CTOs and VPs of Engineering
Filter G2 for job title CTO or VP Engineering and company size 11–200. The review they left about Datadog, Okta, AWS, GitHub, or a SOC 2 vendor is a narrative of the last two quarters of sprawl. 3-star reviews are better than 1-star rants: they wanted the product to work at the next stage. Use substitutes as a map of who else is in the consolidation conversation.
Rules gotcha: Incentivized reviews are obvious and will be used against you on HN. Reply as the vendor on-platform when you are named. Do not hunt reviewers off-platform.
YouTubeevergreen comments
CTO interviews and scale-up war stories
Interviews with scale-up CTOs age; comments do not. Viewers ask which identity provider, which observability stack, and which SOC 2 path the guest actually used. Those commenters are often mid-questionnaire. Pair with 'we outgrew Heroku' and 'AWS bill shock' videos — the comments name replacement criteria like 'no full-time FinOps hire.'
Rules gotcha: Channels delete obvious spam. Answer the question in the comment. Link only if someone asks for the product name.
Xreal-time, high leverage
Startup CTOs on X
CTOs live-tweet a failed enterprise security review, a cloud invoice that hit the board deck, or a vendor that raised prices after the round. Quote-tweet chains where two CTOs name the tool they left are warmer than any intent data. Follow a small set in your category and watch who they reply to — those repliers are often one step earlier in the same consolidation.
Rules gotcha: Do not ratio someone for a stack choice. Public disagreement about build-versus-buy is fine; dunking on a CTO's AWS bill during a layoff week is how you get screenshotted.

How startup CTOs talk about their problems

Search and replies land when you use their words, not your category name. These phrases show up in threads when they are close to buying or switching.

What startup CTOs complain about — and what that means

PainHuntr classifies conversations by intent: actively asking, comparing, frustrated, discussing, or a passing mention. The quotes below are the shape of demand, not a promise that a specific post is live today.

Frustrated
“The enterprise buyer sent a 400-row spreadsheet and our only security-minded engineer is also on-call. I do not need another GRC theater product. I need evidence we can export without pausing the roadmap for a quarter.”
r/startups compliance threads, CTO Craft Slack, and LinkedIn posts after a lost enterprise deal.
Comparing
“Datadog plus Sentry plus a homegrown dashboard plus CloudWatch. The combined bill is now a board topic. We are 30 engineers. We should not need a full-time FinOps person to explain traces.”
Ask HN observability posts, G2 cons filtered by CTO title, and YouTube comments under scale-up CTO interviews.
Actively asking
“Who has actually passed SOC 2 as a 20-person product org without buying four overlapping vendors? Need identity, logging, and a vendor that will not dump another questionnaire on engineering.”
CTO Craft, HN Ask threads, and X conversations after a failed security review.
Discussing
“We said the billing system was temporary in 2023. It is now the reason we cannot ship annual plans. Every billing vendor assumes we have a finance engineer.”
HN billing threads and slower Twitter/X threads after a pricing-change screenshot.

How to reach startup CTOs without getting ignored

Lead with the executive constraint they already named — questionnaire, vendor sprawl, a board-level invoice, a temporary tool that calcified — and put that sentence first. Startup CTOs skim like they are behind on investor updates, because they are. They will take a 15-minute call if you have a customer at a similar stage and a consolidation plan, not a 'quick discovery' that is clearly your funnel. Offer a sandbox with SSO and an audit-log screenshot. Never pitch in a hiring thread or a layoff conversation. If they still write code, a changelog and an architecture note beat a deck. If they just hired a VP, talk about reducing tools, not adding one. Disclose when you sell in the category. These rooms talk to each other; a slimy reply in r/startups will be pasted into CTO Craft.

Frequently asked questions

Are startup CTOs the same buyer as engineering managers?

No. An EM buys the tracker and the incident bot for a team of twelve. A CTO buys consolidation, questionnaires, and anything that shows up on a board slide. Overlap exists on HN and LinkedIn. If you pitch Linear workflows to a CTO you may get a polite intro to an EM. If you pitch vendor sprawl to an EM you will sound like a conference.

Where do startup CTOs complain about SOC 2 and observability bills?

r/startups, CTO Craft, HN Ask threads, G2 cons filtered by title, and LinkedIn when the pain is political. X when an invoice hits the board deck. Watch for questionnaires, sprawl, and 'temporary became permanent' as buying criteria.

Is CTO Craft worth the membership if I sell to CTOs?

Only if you will contribute for months and you already lead or have led engineering. It is not a lead list. Public HN, Reddit, G2, and LinkedIn are easier to monitor at scale. Use CTO Craft after you have a genuine operator note, not a sequence.

How do I tell a title collector from a buyer?

Look for a headcount, a round, a named vendor invoice, or a questionnaire that paused a deal. 'How do I become a CTO' is not a buyer. 'Five monitoring tools and the bill is a board topic' is a buyer. PainHuntr's frustrated and comparing labels exist for that cut.

What should I paste into PainHuntr if I sell to startup CTOs?

Your product URL plus the incumbent they already stack — Datadog, Okta, AWS, a SOC 2 vendor, a billing system they called temporary. The engine looks for people asking for consolidation, comparing vendors, and venting about questionnaires and sprawl. Pair that with the queries on this page if you still want to hunt by hand.
