A founder I know, Marta, runs a mid-market contract management tool. Last spring she closed a $48,000 ARR deal with a logistics company that had been on DocuSign for three years. No cold email. No ABM campaign. She saw a post on r/legaltech where their head of operations wrote, essentially, 'DocuSign support has been useless for six months and we're actively evaluating alternatives.' Marta replied that afternoon. Deal closed in 19 days.
Most people hear that and call it luck. It's not. It's just a process nobody's bothered to build.
G2 reviews are a lagging indicator, not a signal
Here's an opinion that'll annoy some people: monitoring competitor reviews on G2 is mostly a waste of time. G2 reviews are written weeks or months after the frustration peaked, by someone HR asked to fill out a form. The real signal is the live, unfiltered venting that happens on Reddit, LinkedIn, and X before a user even considers leaving. That's the window.
And it closes fast. Someone posts 'I'm so done with [tool], three outages this month' and within 48 to 72 hours they've either been placated by support or they've started a vendor evaluation. Catch them at hour 6 and you're a helpful expert who showed up at the right time. Catch them at hour 96 and you're another cold pitch in a crowded inbox.
Passive annoyance is silent. Public venting is active decision-making with extra steps. The user is processing the switch out loud. They want validation, want someone to tell them there's a better option. That someone should be you.
The signals worth watching aren't the obvious ones
Forget 'Does anyone have a good alternative to [competitor]?' Those posts are real, but you're competing with every SDR who set up a keyword alert in 2022. The higher-value signals don't read like buying intent forms.
They look like this: a VP of Sales on LinkedIn posts that their stack 'keeps growing but results keep shrinking,' three tools tagged in the caption. A thread on r/SaaS where someone says they've been using Outreach for 18 months and 'can't justify renewing at this price for what we get.' An X thread where a founder details a botched onboarding with a named competitor, asks if others have seen the same thing, and gets 40 replies confirming it.
None of those posts are asking for your pitch. They're creating an opening for a real conversation. The difference between a rep who closes from these and one who gets ignored is whether they respond like a person or a sequence.
I ran outbound at my last company using mostly cold email and LinkedIn InMail. 1,400 touches one quarter, 9 meetings booked. The next quarter we started watching competitor threads and responding directly. 220 touches. 11 meetings. The math isn't complicated.
Three churn patterns worth building a process around
Not every complaint converts. Someone venting about a minor UI annoyance is blowing off steam. What you're looking for is structural frustration, the kind that comes from a product or vendor relationship that's fundamentally broken. Three patterns show up repeatedly.
Pricing shock after a renewal or tier change. When a competitor restructures their plans, users broadcast it immediately and publicly. Apollo did this. Intercom did this. Every time it happens, there's a two to three week window where unhappy users are actively searching for alternatives and posting about it everywhere. This is category-level opportunity, and most sales teams miss it because nobody's watching.
Support collapse complaints. These spike when a competitor has an outage, ships a bad update, or has a customer success team stretched too thin after layoffs. One bad support experience, told publicly, pulls in 15 other users who've been quietly frustrated for months. They pile on. That thread is a prospect list.
The 'we've outgrown it' signal. Subtler than the others. A user posts something like 'we started with [tool] when we were 5 people, now we're 40 and it just doesn't scale for us anymore.' No anger, no crisis. Just a quiet announcement that they're in the market. These users convert slower but close bigger, because they've already psychologically moved on before they ever talk to you.
How to respond without sounding like an ambulance chaser
The approach that kills these opportunities: a rep posts 'Hey, sounds like you might want to check out [product], here's our link' within minutes of the original complaint. The original poster feels surveilled. Other readers see a predatory pitch. The thread turns hostile.
What actually works is responding to the emotion before you respond to the problem. Acknowledge that what they're describing sounds genuinely frustrating. If you've seen the same pattern from customers who came from that competitor, say so specifically. 'Three of our last five customers migrated from [competitor] after the same pricing change. Happy to share what that transition looked like if it'd help.' That's not a pitch. It's a data point with an offer attached.
The goal of the first response is not to close. It's to be the most credible, least salesy voice in that thread. You want them to click your profile. You want them to reply. From there, take it to DM, get a call, run your normal process.
Marta's response to that r/legaltech post was two sentences. She said she'd seen a few teams come over from DocuSign after similar support issues and offered to share a migration checklist if it'd help. The prospect replied in 40 minutes.
You can't sustain this manually
If you're a solo founder or a two-person team, you can do this by hand for a week and get a feel for it. Set up Google alerts for '[competitor] alternative,' '[competitor] pricing,' '[competitor] support.' Spend 20 minutes a day on the relevant subreddits. It works. It also consumes you.
The real version of this process watches multiple platforms at once, scores posts by how close the user is to actually switching, and surfaces signals within hours. That's what we built Inbown to do, because the manual version was burning 90 minutes a day of my time and I was still missing half the threads.
But even without a tool, just start watching. Your competitor's unhappy customers are posting publicly right now, on platforms you're already on. They're not hiding.
At least two of the next five deals your closest competitor loses will leave a public trail before the user churns. Whether you're in that conversation is entirely up to you.
