# Find the enterprise opportunities hiding in your product signups > Manifolds identifies the people and companies behind your product signups, including personal emails, so sales can find VIP signups and bottom-up account adoption while intent is still high. Manifolds is a deanonymization tool built for high-volume PLG companies. Sales teams use Manifolds to identify the people and companies signing up for their product, figure out which ones to pay attention to, and act while intent is still high. Sometimes that's a VP evaluating your product with a personal email. Sometimes it's a dozen employees from the same company adopting your product from the bottom up. Manifolds helps you find both. Read on to learn how. ## Your next enterprise customer might already be using your product Enterprise opportunities tend to show up in a PLG product in two ways. ### VIP SIGNUPS Sometimes the buyer shows up directly. A VP of Engineering signs up to kick the tires. A founder starts evaluating your API. An engineering leader creates an account because someone on their team sent them a link. They might use `jack.barker@hooli.com`. They might use `jbarker@hoolimail.com`. Either way, someone your sales team should know about is already evaluating your product (and probably send them an email or a LinkedIn connection). ### BOTTOM-UP ADOPTION WITHIN A COMPANY Other times, adoption happens from the bottom up. One engineer signs up. Then another. A few weeks later, a dozen people from the same company are using the product. Some use work emails. Others use Gmail or iCloud. Nobody has filled out an enterprise contact form. This is especially common at larger companies, where users may want to try a product without kicking off a slow, formal purchasing process. There may not even be an opportunity in your CRM. But the company is already adopting your product. *Figure: TWO TYPES OF OPPORTUNITY.* Two paths to the same sales opportunity. On the left, a single personal-email signup resolves to the CEO of a company with more than ten thousand employees. On the right, four separate signups on personal domains resolve to the same organization. Both paths converge on one sales opportunity. ## Signup is a sales signal Most PLG sales teams focus on accounts that have already activated – and especially the ones that signed up with work emails. That misses a lot. Some of your best activated users may have used personal emails. Others may never activate at all. A buyer might sign up just to kick the tires because someone on their team told them to take a look. The signup itself is a signal. Manifolds helps you figure out which ones are worth acting on before they disappear. ## At scale, you can't research every signup This is manageable when you have 100 signups a month. A founder can watch the signup channel, recognize a few company domains, Google an interesting person, and send a message when something catches their eye. In our experience, that stops working around 1,000 monthly signups. And forget about 100,000 signups a month, which is a typical volume for a Manifolds customer. At that point, even the easy signups are hard to act on. Knowing that `dinesh@piedpiper.com` works at Pied Piper doesn't help much if Dinesh is one row among thousands. They look like this: *Figure: A DAY OF SIGNUPS.* A dense list of 72 signup email addresses on mixed personal and work domains, fading out into thousands more. None of them is visually distinguishable from the others. Your sales team doesn't need to investigate everyone who signs up. They need to know which ones are worth their time. Manifolds alerts you in real-time when those signups come into your product, wherever you want the alert: Slack, email, a daily digest, or otherwise. ## Identify the people behind the emails Work emails give you a clue about where someone works. Personal emails don't. That's a hard problem for PLG companies – and especially certain industries, like developer tools, where users love to use personal emails. However, across industries, people often try software on their own before their employer is involved in the buying process. Manifolds takes an email address and figures out who's behind it. We search across multiple data providers and do our own research to identify the person and company. We also take care to make sure we've found the right person. So this: `jbarker@hoolimail.com` can become this: *Figure: IDENTITY RESOLUTION.* The address jbarker@hoolimail.com resolving into a record: Jack Barker, CEO of Hooli, a company of 10,001 or more people, with the work email jack.barker@hooli.com and a LinkedIn profile. Every day, we identify founders and executives of multibillion-dollar companies, VPs at Fortune 500 companies, and other prominent users who signed up with personal email addresses. Without deanonymization, they look like any other Gmail signup. ## Research what matters to your business Manifolds can research the things that make a signup valuable to your business – even when they aren't standard enrichment fields. Does this company sell software to developers? Does this company use Kubernetes? Is this person likely to be involved in buying infrastructure? Because we research each person and company when we deanonymize them, we can enrich your signups with information specific to your business. *Figure: RESEARCH RECORD.* An enrichment record in three parts: person details for Jack Barker, company details for Hooli, and researched attributes including funding, YC status, and vertical and capability tags. ## Decide which signups your sales team should see Once you know who's signing up, you can decide which ones are worth sending to sales. The logic can be simple. IF seniority >= VP AND company size >= 1,000 THEN notify sales Or it can use information specific to your business. IF company funding >= $50M AND sells to developers = true THEN notify sales You can also combine several signals into a score. Role, seniority, company size, funding, industry, technologies, and your own custom research can all contribute to whether a signup is interesting. ## Sometimes the opportunity is the account Not every enterprise opportunity starts with a VP. Sometimes it starts with one engineer. Then another. Then five more. None of those signups may look especially important on their own. Together, they're telling you something much more interesting: a company is adopting your product organically. *Figure: ACCOUNT RECONSTRUCTION.* Six identified users at Pied Piper, five of them signed up with personal email domains, grouped as one organization. PIED PIPER *Identified users at Pied Piper, with job title and the email domain they signed up with* | NAME | TITLE | SIGNED UP WITH | | --- | --- | --- | | Richard Hendricks | Founder / CEO | hoolimail.com | | Bertram Gilfoyle | Systems architect | neutron.me | | Dinesh Chugtai | Software engineer | piedpiper.com | | Jared Dunn | COO | ishroud.com | | Carla Walton | Engineer | hoolimail.com | | Priyanka Singh | Software engineer | hoolimail.com | 6 IDENTIFIED USERS same organization This is especially hard to see when people use personal emails. We've found large adoption patterns inside public companies where most users signed up with personal email addresses. Looking at email domains alone would make those users look unrelated. Manifolds can identify those people and connect them back to the same company, and help you understand the signup pattern. Now sales can treat the company as an account instead of treating six engineers as six unrelated leads. You can find the right buyer and start a conversation about enterprise features, security and compliance, support, centralized purchasing, volume pricing, or whatever makes an enterprise plan useful for that company. ## Act while the signal is fresh Finding a good opportunity isn't very useful if it sits in a dashboard. Manifolds can push results to Slack, your CRM, your warehouse, or anywhere you can send data with a webhook. It can also help you automate outreach to valuable signups. Some customers use Manifolds to trigger a personalized email based on who signed up and why they're interesting. *Figure: ROUTING.* A signup enters Manifolds, and the result branches out to Slack, a CRM, a warehouse, and a webhook, which can in turn reach whatever you want. ## How it works You don't need to change your signup flow to use Manifolds. The basic setup is simple – and starts with sending us an API call when a user signs up. 1. ### Send us the signup When someone creates an account, send their email address to Manifolds. REQUEST ``` POST https://api.manifolds.run/v0/enrichments Authorization: Bearer mf_live_... Content-Type: application/json Idempotency-Key: 9b7c6a2a-4a8b-4d8e-9f3e-3b1d1a7a8b9c { "email": "jbarker@hoolimail.com" } ``` 2. ### Manifolds identifies and researches them We identify the person behind the email and research them and their company. RESPONSE · 202 ACCEPTED ``` { "status": "accepted", "submission_id": "subm_11111111-1111-1111-1111-111111111111", "received_at": "2026-04-13T15:59:12Z", "idempotency_replayed": false } ``` 3. ### Qualify the opportunity Use the information that matters to your business. That might be a simple rule: `seniority >= VP` Or something more specific: `seniority >= Director` `company_size >= 500` `sells_to_developers = true` You can also use a score or classification when simple rules aren't enough. 4. ### Send the result where you need it Manifolds can broadcast the result to your systems. WEBHOOK · enrichment\_card.created ``` { "event": "enrichment_card.created", "version": 1, "enrichment_id": "enr_33333333-3333-3333-3333-333333333333", "submission_id": "subm_11111111-1111-1111-1111-111111111111", "organization_id": "22222222-2222-2222-2222-222222222222", "occurred_at": "2026-04-13T16:00:00.000Z", "delivery_id": "66666666-6666-6666-6666-666666666666", "data": { "person": { "email": "jbarker@hoolimail.com", "workEmail": "jack.barker@hooli.com", "fullName": "Jack Barker", "jobTitle": "CEO", "roleSeniority": "c_level", "emailAffiliation": "personal", "linkedinUrl": "https://www.linkedin.com/in/jackbarker" }, "company": { "name": "Hooli", "website": "https://hooli.com", "sizeBucket": "10001+", "sizeMin": 10001, "sizeMax": null, "isYc": false, "totalFundingUsd": "180000000", "verticalTags": ["software_it"], "capabilityTags": ["custom_software_services"] } } } ``` Send it to Slack. Create or update a record in your CRM. Join it with product activity in your warehouse. Trigger an internal workflow. Start an automated sequence. Or just give a salesperson enough context to write a good email. ## Why Manifolds There are plenty of ways to enrich an email address. We built Manifolds for a harder problem: finding sales opportunities in a large stream of product signups. **Personal emails aren't dead ends** Manifolds searches across multiple data sources and does its own research to identify users that traditional enrichment misses. That's especially important for PLG companies, where some of your most valuable users may sign up with Gmail, iCloud, Outlook, or another personal email. **We take accuracy seriously** Finding more people doesn't help if you can't trust the result. We take extra steps to make sure the person we return is actually the person who signed up. **Research whatever matters to your business** Company size and job title are useful. They aren't always what defines a good prospect. Manifolds can research questions specific to your business instead of limiting you to a fixed set of enrichment fields. **Built for product signups** Deanonymizing product users isn't one feature among many for Manifolds (like it is for most of our competitors). It's the foundation of our product. We built identity resolution, person and company research, qualification, account recognition, and routing around one basic question: **Who are my users?** ## See who's signing up for your product Your next enterprise opportunity might already have an account. Send Manifolds an email address and see what comes back. [Get started](https://manifolds.run/signup) Canonical page: https://manifolds.run/use-cases/sales
