| Setup time | Minutes to the first source: sign in with Google, paste a LinkedIn profile, company page or post URL, or enter keywords, and leads appear progressively during the first sync. Tuning ICP filters and caps takes a few days of watching what comes in. | Fifteen minutes. Sign up, filter the database to your categories, track the topics that look relevant, and the alerts do the rest. There is nothing to configure and nothing to connect. |
| Learning curve | Low. Most of the value comes from choosing sources whose audience matches your ICP, and the Engagement Agent can set those up from a list of topics. | Low mechanically, moderate interpretively. Reading the interface is trivial; distinguishing a durable shift from a novelty spike, and resisting the pull of an impressive-looking curve on a tiny base, is the actual skill and it takes a few months of watching to develop. |

Strengths and limitations
Cornersight
Strengths
- Engagement-based lists reach people who are active on LinkedIn right now, which a filter on recent posters misses because most users react far more than they post.
- No LinkedIn account connection, so there is no session to hand over and no restriction risk on the buyer's own profile.
- A credit model tied to unique people per source, with free fetching and free failed lookups, keeps the bill tied to prospects rather than activity.
- Daily re-syncs capture engagement that arrives days after a post goes live, not just a snapshot at the moment of tracking.
Limitations
- LinkedIn only; buyers who are quiet there, or active elsewhere, produce no signal.
- No job-change, funding, hiring or website-visitor signals, so it covers one slice of the intent landscape.
- Launched in January 2026 and rebuilt in May, so the track record is months long and the product is still changing quickly.
- No published SOC 2, SSO or data-residency options, which rules it out for formal enterprise procurement.
Exploding Topics
Strengths
- Genuinely early detection on fast-moving consumer and technology categories, which is a materially different output from keyword tools that report what is already large.
- Growth stage labelling is the underrated feature: knowing a topic has already peaked saves more money than knowing one is rising.
- Meta trends turn a scatter of individual topics into a thesis, which is what makes the output presentable to a board or a client.
- Cheap by any standard in this category, starting at $39 with a 7-day trial and a substantial free browsing experience.
Limitations
- No company or contact data of any kind, so it cannot feed a sales motion directly and does not belong in an outbound stack.
- CSV export starts at $99, making the $39 headline price misleading for anyone who intended to use the data outside the interface.
- Attention is not demand. A trend can grow enormously in search and conversation while nobody spends money, and the platform cannot distinguish the two.
- Coverage skews toward consumer, ecommerce, and technology topics; slow-moving professional and industrial B2B categories generate few useful detections.
Pricing compared
Cornersight
Self-serve monthly plans metered in credits, where one credit is one unique person per monitor, with a free trial on every plan and spend caps per source, per search, per team and for the Engagement Agent.
- Starter$99
- Growth$169
- Pro$329
- Scale$599
Cornersight is good value for a team whose buyers live on LinkedIn. $99 a month buys 15,000 unique, enriched engagers, with every delivery route included on every plan, and the per-person credit definition means heavy repeat engagement does not inflate the bill. Against a manual workflow of exporting post engagers and enriching them separately, it pays for itself in hours saved within the first week. The limits are scope and maturity rather than price: one network, no company-level events, and a product less than a year old.
Exploding Topics
Flat monthly subscription across three tiers, metered on tracked trends and trend analyses.
- Entrepreneur$39
- Investor$99
- Business$249
Model it by outcome rather than by record, because there is no per-record unit here. At $39 a month, Entrepreneur costs about $470 a year and needs to change one content or inventory decision to pay for itself, which is a low bar for anyone in a fast-moving consumer or technology category. At $99, Investor adds forecasting and export and is the right plan for anyone whose output is a spreadsheet or a report rather than a decision in their own head. At $249, Business is agency pricing and only makes sense across many clients or categories. The value question is not really the price, it is whether your market moves fast enough to have trends worth catching, and for a large slice of B2B the honest answer is no.
Editorial verdict on each
Cornersight
Best ValueCornersight is the tool to buy if your buyers are active on LinkedIn and you want the people engaging with your competitors, your category voices or your own content as enriched leads every morning. It does one signal thoroughly, re-syncs daily so late engagement is not lost, charges per unique person rather than per interaction, never touches your LinkedIn account, and delivers into HeyReach, a CRM or an AI agent on every plan from $99 a month. Its limits are clear: one network, no company-level events, and a product less than a year old with no compliance paperwork. With Trigify closing, it is the most direct replacement in this category for a LinkedIn engagement motion, and the free trial makes testing it on a handful of competitor profiles a low-risk afternoon.
Read the full Cornersight profileExploding Topics
Exploding Topics is the cheapest useful answer to a question no other tool in this category addresses: what is about to matter. For $39 a month it will reliably surface subjects in fast-moving consumer and technology categories months before they show up in a keyword tool, and the growth stage labelling stops you from chasing things that already peaked. Buy Investor at $99 rather than Entrepreneur if you intend to use the data anywhere outside the interface, because export starts there. Read the free newsletter for two months first, since it exposes the actual quality of the detection at no cost, and be honest about your market: if you sell into a slow, mature B2B category, this database will have very little to say to you. And do not confuse it with a sales tool, because it will never hand you a single account to contact.
