Best Social Listening Tools in 2026: 10 Picks for Startups

The best social listening tool for a startup is the one that watches the places your buyers ask for help (usually Reddit, X, Hacker News and LinkedIn) and tells you which mentions come from people ready to buy. For free keyword alerts, start with F5Bot or Google Alerts. For finding buyers across many platforms, use a tool that scores intent, such as Prospy, Syften or Octolens. Enterprise suites like Brandwatch and Sprout Social are built for big brands with big budgets.

Most "best social listening tools" lists are written for agencies and enterprise teams, and rank tools on sentiment dashboards and Instagram coverage. A startup needs something narrower: find the few posts a day where someone asks for a product like yours, before the thread goes cold. This guide compares 10 tools on that job, with prices checked on each vendor's own site on November 9, 2026.

The short version

• Free: F5Bot (Reddit, Hacker News, Lobsters) and Google Alerts (the web) cost nothing and catch your brand name. Neither tells a buyer from a bystander. For a one-off look that does, our free Social Mention Search scores the last week of mentions for buying intent, no signup.
• Under $100 a month: KWatch, Syften, Awario and Prospy. Pick by platform coverage and by how well each one filters noise.
• Built for B2B and developer tools: Octolens, from $159 a month billed annually.
• Brand and PR teams: Brand24 starts at $199 a month billed annually. Sprout Social and Brandwatch sell listening through sales calls.
• What decides it: the platforms your buyers use, and whether the tool ranks mentions by intent.

What a startup needs from social listening

Enterprise listening asks "how do people feel about our brand?" Startup listening asks "who needs us today?"

1. The right sources. B2B buyers ask for recommendations on Reddit, X, Hacker News and LinkedIn. Consumer apps add TikTok and YouTube. Instagram and Facebook matter less than most lists suggest for software.
2. Intent, not volume. "CRM" matches thousands of posts a week. You want the handful where someone writes "looking for a CRM that…". AI filtering or scoring is the difference between a useful feed and an inbox you stop opening.
3. A price that fits pre-revenue. Seat-based enterprise pricing and "book a demo" pages are a bad fit for a team of two.
4. A way to act. Slack or email alerts, an API, and increasingly an MCP server so your AI assistant can read the feed.

The 10 best social listening tools for startups

1. F5Bot

F5Bot emails you when your keywords appear on Reddit, Hacker News or Lobsters.

• Price: Free plan. Silver is $12.99 a month for 20 keywords (marked for non-commercial use). Gold is $49.99 a month for 200 keywords, RSS and JSON feeds, AI filtering, Slack and Discord.
• Fits: a founder who wants to know when someone names the product.
• Weakness: three sites only, and the free plan matches words, not meaning. See our guide to Reddit keyword alerts for taming the noise.

2. Google Alerts

Google Alerts watches pages in Google's index. You can pick sources (news, blogs, web, video, discussions) and get results as they happen, daily or weekly.

• Price: free.
• Fits: catching press, blog posts and directory listings about you.
• Weakness: it only sees what Google has indexed, so social posts arrive late or not at all. A backup, not a main feed.

3. KWatch

KWatch monitors Reddit, Hacker News, X, YouTube, Facebook and LinkedIn, with limits per platform.

• Price: Free covers 2 Reddit and 2 Hacker News keywords. Essential is $19 a month (20 Reddit, 20 HN, 2 X, 2 YouTube, 1 Facebook and 1 LinkedIn keyword, plus AI analysis). Business is $79 and adds API, webhooks, Slack and MCP. Enterprise is $199.
• Fits: Reddit-first founders who want AI analysis cheaply.
• Weakness: X and LinkedIn keywords are scarce on the lower plans, which is where many B2B buyers ask.

4. Prospy

Prospy watches your keywords on X, Reddit, Hacker News, Bluesky, YouTube, LinkedIn, Threads, TikTok, Quora, Product Hunt, GitHub and Medium, and scores every mention with AI for relevance and buying intent. A post asking "what do you use for X?" ranks above a post that only uses your keyword. It also flags Reddit, Hacker News and YouTube threads that already rank on Google for your keywords, the threads AI assistants tend to cite, so you know where one reply keeps getting read.

Prospy never posts for you. It finds and scores the conversations. If you work with an AI assistant, connect Claude, ChatGPT or Cursor to Prospy's MCP server; the assistant reads the scored mentions and drafts replies; you post them from your own account.

• Price: see pricing.
• Fits: startups whose buyers are spread across Reddit, X, LinkedIn and Hacker News, and anyone who wants an AI agent to work the feed.
• Weakness: keywords are scanned once a day, so it suits a daily routine, not minute-by-minute crisis monitoring. It does not cover Instagram, Facebook, news sites or podcasts.

5. Syften

Syften monitors Reddit, Hacker News, Indie Hackers, GitHub, Product Hunt, Stack Exchange, Dev.to, Bluesky, Mastodon, Slack communities, newsletters, podcasts and the web, with X and YouTube as add-ons.

• Price: Entry $29.95 a month (3 community filters, 100 results a day). Standard $49.95 adds AI filtering and Slack. PRO $119.95 adds webhooks, MCP and full archive search. X monitoring is +$40 a month and YouTube +$20 on Standard and PRO. 14-day free trial of PRO.
• Fits: developer-tool founders who like writing precise filters.
• Weakness: no LinkedIn, and X costs extra. We compare the two in detail on Prospy vs Syften.

6. Octolens

Octolens covers Reddit, X, LinkedIn, Bluesky, Hacker News, GitHub, YouTube, TikTok, Stack Overflow, DEV and review sites, with podcasts, news and newsletters on its higher plan.

• Price: Pro $199 a month, or $159 a month billed annually (10 keywords, 15,000 mentions, hourly refresh). Scale $499 a month billed annually (40 keywords, real-time). 7-day free trial, no free plan.
• Fits: funded B2B and developer-tool teams that want fast refreshes and API access.
• Weakness: ten keywords for $159 or more a month is a lot before revenue.

7. Awario

Awario tracks X, Facebook, Instagram, Reddit, YouTube, Vimeo, blogs, forums, news and the web.

• Price: Starter $29 a month billed annually or $49 month to month (3 topics, 30,000 mentions a month). Pro $89 or $149. Enterprise $249 or $399. Free trial of Starter.
• Fits: consumer brands that want wide coverage cheaply.
• Weakness: it does not list LinkedIn or Hacker News, and it counts mentions rather than finding buyers.

8. Brand24

Brand24 is a mature brand monitoring tool with sources from X, Reddit and LinkedIn to TikTok, news, podcasts and review sites.

• Price: Individual $249 a month, or $199 billed annually (3 keywords, 2,000 mentions, updates every 12 hours). Team $349, Pro $499, Business $699 month to month. 14-day free trial.
• Fits: marketing and PR teams that report on reach, sentiment and share of voice.
• Weakness: the entry plan gives you three keywords and twice-daily updates for $199 or more. See how it compares on Prospy vs Brand24.

9. Sprout Social

Sprout Social is a social media management suite with listening sold separately.

• Price: plans start at $79 per seat a month on annual billing ($99 billed monthly). Listening is an add-on for the Standard plan and up, priced through a demo. 30-day free trial.
• Fits: teams that already run their social accounts in Sprout.
• Weakness: you pay per seat for a suite, then again for listening.

10. Brandwatch

Brandwatch is enterprise consumer intelligence with deep historical data.

• Price: not published. You book a demo.
• Weakness: built for analysts, priced for enterprises.

How to choose

• "I want to know when someone names my product." F5Bot free plus Google Alerts. Spend nothing until the volume gets annoying.
• "I want people asking for a product like mine." You need intent filtering. Prospy, Syften, KWatch or Octolens, depending on platforms and budget.
• "My buyers are on LinkedIn and X too." Check per-platform limits. Several cheap plans cap X and LinkedIn at one or two keywords, or sell them as add-ons.
• "I want my AI agent to do the first pass." Look for an MCP server or an API. Prospy, Syften PRO and KWatch Business all list MCP.

A setup that finds buyers in the first week

1. Add four kinds of keywords: your brand, competitor names, request phrases ("any recommendations for [category]", "alternative to [competitor]") and your customers' own words for the problem.
2. Leave every source on for a week, then turn off the platforms that only produce noise.
3. Sort by intent, not date. Read the top ten mentions each morning and ignore the rest.
4. Reply first where the thread ranks on Google. A Reddit thread on page one keeps sending readers for months, and Ahrefs found that mentions in Reddit threads that rank had the strongest correlation with brand visibility in AI answers of any mention type it measured (November 2026).
5. Reply as yourself. Answer the question, name other options, disclose that you built the product. Never use fake accounts or buy votes.
6. Prune weekly. Drop keywords that found nothing useful in two weeks; add phrases from good threads.

FAQ

What is the best social listening tool for a startup?

The one that covers the platforms your buyers use and ranks mentions by buying intent. For free alerts, F5Bot and Google Alerts. For finding buyers across Reddit, X, LinkedIn and Hacker News, Prospy, Syften, KWatch or Octolens, depending on budget and platforms.

Is there a free social listening tool?

Yes. F5Bot is free for Reddit, Hacker News and Lobsters, Google Alerts is free for the web, and KWatch has a free plan for two Reddit and two Hacker News keywords. Free plans match keywords but do little to filter for intent.

What is the difference between social listening and social media monitoring?

Monitoring collects mentions of your keywords. Listening adds analysis: what people want and how they feel. For a startup, the useful part is spotting intent, the posts where someone is asking for a solution.

Which social listening tools cover Reddit and LinkedIn?

Prospy, Octolens, Brand24 and KWatch list both. Syften covers Reddit but not LinkedIn. F5Bot and Awario cover Reddit but do not list LinkedIn.

Can a social listening tool reply to posts for me?

The tools in this list do not post for you, and that is a good thing: automated replies get accounts banned and read as spam. A better setup is to let the tool find and score the threads, have your AI assistant draft a reply, and post it yourself.
