Topsail vs Wavo (2026)
The decision is whether you need to see how the list was built. Both vendors sell access to prospects that mainstream tools miss, and both do it by sourcing rather than by filtering. Wavo publishes the method because the method is the pitch: brands are identified through how their stores actually operate, using traffic patterns, advertising activity, technology stack and revenue signals, and the vendor states plainly what it does not use, naming professional network profiles and purchased lists and identifying two competitors that rely on the former. It also puts a number on the gap it serves, publishing an analysis of 2.8 million United States ecommerce brands concluding that roughly forty percent are absent from the databases most agencies license. Topsail operates its lead engine on the customer's behalf and describes it by component rather than by method, combining customer profile criteria, specialty databases, intent signals, research, scoring and contact data. A customer cannot inspect or adjust the sourcing criteria the way they could a filter they built themselves, and if the definition drifts they would learn it from results rather than from configuration.
- You want the day's decisions removed rather than assisted. A representative opens the platform and the correct account and the next sequence step are already determined, with the playbook, research and calling in the same place, so discretion over what to work is removed rather than merely guided.
- The reporting has to answer whether the work is happening. The vendor names the problem directly, that reliable pipeline begins with the accounts being worked, the outreach completed and the follow up seen through, and builds reporting around giving a leader activity they can trust is real.
- You want nobody on your team becoming an administrator. Topsail configures the workspace and maintains the account on the customer's behalf, so the sales team does the selling and the platform work belongs to the vendor, with support staffed in the United States.
- Your prospects are not on the professional network. The database is built from storefront signals rather than profiles, on the argument that most people running profitable ecommerce brands do not maintain one, so the tools every agency uses share the same blind spot.
- You want references with employers and figures attached. Five named individuals with roles and companies report specific outcomes, including a five to one close rate against other sources, a four percent response rate against under one percent from traditional databases, and growth from seven staff to forty five over seven years with this as the leading client source.
- Sending discipline should ship with the data. Built in warmup, address rotation, custom tracking domains, authentication, domain monitoring, duplicate detection on import and automatic suppression of contacts already reached, alongside a founder who publishes an argument for fifty relevant messages over five thousand poor ones.

The short version of each
Topsail
Topsail sells prospecting discipline to teams whose market is too specific for generic outreach to reach, running a configured daily workflow where a representative opens the platform and the correct account and next sequence step are already determined, with the vendor finding the leads, configuring the workspace and maintaining the account on the customer's behalf. The GTM Tech Index grades it B on segment and market coverage because the buyer is defined by what does not work for them rather than by a size band: the vendor states its market as specialised teams whose business development depends on a specific market, a defined territory or a highly personalised motion, and explicitly declines the teams for whom volume works.

Wavo
Wavo sells a contact database of ecommerce store owners who do not appear in the databases everyone else licenses, identifying brands through how their stores actually operate using traffic patterns, advertising activity, technology stack and revenue signals, then resolving who owns the brand, with a sending platform bundled around it. The GTM Tech Index grades it B on segment and market coverage because the segment is defined by a number rather than a persona: the vendor's published analysis puts roughly forty percent of the United States ecommerce brand universe outside mainstream databases, and that figure is simultaneously the market definition, the reason to buy and a falsifiable claim. The index grades it D on data privacy posture.

Common questions
Is Topsail better than Wavo?
Whether you need to see how the list was built. Both sell access to prospects mainstream tools miss, and both do it by sourcing rather than filtering. Wavo publishes the method because the method is the pitch, identifying brands through traffic patterns, advertising activity, technology stack and revenue signals and stating plainly what it does not use. Topsail operates its engine on the customer's behalf and describes it by component, so a customer cannot inspect or adjust the sourcing criteria the way they could a filter they built themselves.
How does each define the market it serves?
Wavo puts a number on it and Topsail does not. Wavo publishes an analysis of 2.8 million United States ecommerce brands concluding that roughly forty percent are absent from the databases most agencies license, on a dedicated page, which makes the central product thesis falsifiable rather than merely asserted. Topsail defines its market by exclusion instead, stating that when business development depends on a specific market, a defined territory or a highly personalised motion, open ended lists and generic filters stop working, which is a self selecting definition a reader either recognises or does not.
How much do Topsail and Wavo cost?
Neither publishes a price. Topsail has no pricing page in its navigation at all, and because the vendor sources leads, provides the platform and maintains the account, nothing indicates which of those three the commercial model rests on. Wavo publishes no figure on its own site or on any of five software directories, all of which record pricing as available on request, and gates even the free trial behind a booked fifteen minute call during which the vendor filters the database to the buyer's niche with them.
Which one addresses deliverability?
Wavo publishes the mechanics and Topsail publishes none. Wavo ships built in warmup, address rotation, custom tracking domains, mail authentication, domain monitoring, duplicate detection on import and automatic suppression of contacts already reached, with the founder arguing publicly for lower volume. At Topsail no warm up, authentication guidance, rotation, bounce handling, sending limit or caller identity management is described, with volume low by design as the mitigating factor and nothing stating whether calls and mail route through vendor infrastructure or the customer's own.
What security documentation does each publish?
Both publish something and only one is a security document. Topsail publishes a subprocessor list as its own linked document alongside a privacy policy, terms of service and a cookies page with an explicit choices control, which is rare at this size, and no security page, certification, audit, encryption statement or vulnerability disclosure route sits behind it. Wavo's entire security disclosure is a single line on the features page about role based access and encryption, plus a pointer to a Safety and Security document that the terms define as binding and that is not published.
How does the GTM Tech Index grade Topsail and Wavo?
Both are graded on the same seventeen capability and compliance axes from public sources, and both sit at eleven axes graded above the floor, the lowest documented depth in this sub lane. The GTM Tech Index grades Wavo B on operational and outcome evidence, platform terms exposure, deliverability discipline and segment coverage, with D on data privacy posture, AI safety and stewardship, residency, security certifications, commercial transparency and exit. Topsail takes B on autonomy and oversight, data privacy posture, platform terms exposure, recipient disclosure and segment coverage. The index publishes no composite score and declares no winner.

Wavo's privacy policy describes a different product from the one being sold, and the difference is the entire database. It was last revised in June 2021 and covers a tool where the customer uploads their own contacts, committing firmly that such data will never be shared or used, which is a real commitment properly drafted.
What it never mentions is the contact file the product is now sold on: personal data concerning hundreds of thousands of store owners, assembled from store signals and public records without those people ever interacting with the company, with no privacy notice, no stated lawful basis, no retention period and no rights attached to it anywhere.
A second privacy policy remains live at a different path with a different corporate address, so two conflicting notices are published simultaneously. The named data protection officer is the founder and chief executive, which is the conflict the role exists to prevent.
The policy advises anyone wishing to remain anonymous to use private browsing so the company is unable to collect any data, which is incorrect and which the same document contradicts four paragraphs later by listing the server log fields private browsing does not affect. And a document titled Safety and Security is defined by the terms of use as part of the binding agreement and is published nowhere, so a customer is contractually bound to a security document they cannot read.
Topsail's version of the same gap is narrower and structurally identical. Because the vendor operates the lead engine itself, the people in a customer's daily queue were selected by Topsail rather than by the customer, and no consent basis for contacting them is stated. Neither vendor publishes a route by which a person in either database can see or remove their own record. At Wavo the removal clause grants that right to every user, meaning every customer, and a store owner whose address was assembled from store signals is not a user.
