Alternative Signals: How to Find Future Buyers Before Your Competition
Estimated reading time: 4 minutes
In mature markets, volume wins. Blast enough emails, hit quota.
In sustainability and carbon, that playbook fails. Everyone already knows the existing buyers. The same 200 companies show up on every prospect list. The same decision-makers get hammered by the same vendors.
The edge is finding future buyers before anyone else does.
The Problem with Obvious Signals
Most sales teams rely on the same sources:
- Registry data (Verra, Gold Standard)
- Sustainability reports
- CDP disclosures
- Industry databases
These signals are valuable. They're also visible to everyone. By the time a company appears in a registry or publishes an ESG report, your competitors have already reached out.
You're not early. You're in line.
Alternative Signals: Where Future Buyers Reveal Themselves
Future buyers send signals before they show up in official channels. The question is whether you're watching.
1. Conference Activity
Conferences are intent signals hiding in plain sight.
- Sponsors are companies investing money to be associated with a topic
- Speakers are individuals positioning themselves as experts (often because they're building something)
- Attendees are people spending time and budget to learn
A sustainability director who attends three carbon market conferences in six months is telling you something. A company that sponsors a climate tech event for the first time is signaling a strategic shift.
Most salespeople wait for the post-conference attendee list. By then, everyone has it.
2. Job Transitions
When your ideal buyer persona changes companies, two opportunities emerge:
- The person who moved now has budget and mandate at a new organization
- The company that hired them just signaled they're investing in that function
A company hiring their first Head of Sustainability is a different signal than a company with an established team. Both matter, but they indicate different stages and different conversations.
3. LinkedIn Engagement Patterns
Forget who posts. Watch who engages.
When someone likes, comments, or shares content about carbon credits, net-zero commitments, or climate disclosure regulations, they're revealing interest. Most of these people will never post about it themselves.
The signal is the reaction, not the content.
Layer this with your buyer persona criteria: Does their title match? Does their company fit? Are they engaging repeatedly or once?
4. News and Announcements
Companies announce sustainability commitments before they build the infrastructure to deliver them.
- Net-zero pledges
- Science-based targets
- New sustainability hires
- Partnership announcements
These announcements create a window. The company has made a public commitment but hasn't figured out how to execute. That's when they need help. Six months later, they've either found vendors or deprioritized the initiative.
5. Competitive Intelligence
Your competitors have already done prospecting work. Their connections, followers, and engagement reveal who they're targeting.
- Who follows your competitor's company page?
- Who engages with their content?
- Who are their salespeople connected to?
You're not copying their list. You're mapping the market they've identified and finding what they missed.
The Noise Problem
From salespeople already doing this: alternative signals work, but the noise ratio is brutal.
Every popular post on carbon credits gets 50 reactions: 48 from thought leaders, students, and marketers. For every genuine future buyer, you'll find:
- Students and researchers with no buying authority
- Competitors doing their own research
- Consultants and vendors, not buyers
- People with passing curiosity, not real intent
Unless luck puts the right signal in front of you at the right time, you'll spend hours sifting through noise to find one gem.
Why Automation Changes the Equation
The answer is systematizing the filter.
You already have heuristics for what makes a good prospect:
- Title patterns that indicate decision-making authority
- Company characteristics that suggest budget and need
- Engagement patterns that separate curiosity from intent
The problem is applying those heuristics manually at scale. You can't personally monitor every conference, track every job change, and watch every LinkedIn reaction.
Automation flips the model. Instead of you hunting for signals, signals come to you, pre-filtered through your criteria. When the system catches something that matches your heuristics, you get notified. Or better: the system acts on it, all the way to personalized outreach.
Why This Matters More in Sustainability
Tech sales teams have been doing signal-based prospecting for years. Funding announcements, executive promotions, product launches: these triggers are well-established.
Sustainability is different:
- Signals are more fragmented. There's no Crunchbase for carbon markets.
- Context matters more. A "sustainability hire" could mean compliance, marketing, or genuine strategic investment.
- The market is still forming. New buyers emerge constantly as regulations tighten and corporate commitments accelerate.
This complexity is exactly why the opportunity exists. The sales teams that build systematic signal-detection for sustainability will have an edge that compounds over time.
The First-Mover Advantage
In niche markets, being first matters more than being slightly better.
The sustainability director who just started at a new company will take meetings with the first few vendors who reach out. By the time they've had five conversations, they're not taking more calls. They're evaluating the options already in front of them.
Alternative signals don't make you smarter. They make you earlier. In niche markets, earlier wins.
