OptaReach vs Selix AI (2026)
The decision is how much you can learn before entering a sales process, and these two sit at opposite ends of the index on it. OptaReach publishes the most complete commercial disclosure in this sub lane: three tiers carrying real monthly figures, a seven line credit rate card with unit rates, and charging rules stated against its own interest, so a buyer can compute the bill before speaking to anyone. Selix AI's clearest pricing statement sits in its terms of service, which say that fees are set out in an order or will otherwise be communicated to the customer later. The two are otherwise close in shape. Both run autonomous agents, both operate their own sending infrastructure with inbox warming, and both put oversight in a shared channel rather than a dashboard, Selix in a team messaging channel where the agent narrates its reasoning as it works, OptaReach in a shared inbox where drafts are reviewed and ownership assigned.
- You have to justify the spend before you can start an evaluation. All three tiers carry a real monthly figure with the discount at each term stated as a percentage, seven credit line items carry published unit rates, and a fourteen day trial requires no card, so the bill is computable before anyone speaks to sales.
- Your buyers are in developer communities rather than in an inbox. Seven channels connect as first class surfaces with their own campaign types and lead sources, covering a discussion forum, a code hosting platform, a technology news aggregator and a developer question and answer site alongside email and the professional network.
- You need a documented interface rather than an implied one. OptaReach publishes a public interface on its own subdomain with an authentication guide, a specification and an endpoint reference, plus webhooks and seven named application integrations, where its counterpart publishes no interface documentation, authentication scheme or connector list.
- You want oversight the whole team can see. The agent posts what it is researching, what it has found and what it plans to do next into a team messaging channel, asks when it reaches a decision that benefits from human judgement, and surfaces proposed actions for review, so a wrong assumption is catchable before it propagates into a hundred messages.
- You want a vendor that will tell you not to buy. Selix publishes three disqualifiers, stating the platform works best with companies that are post product market fit, run a dedicated outbound team and have a mature sales stack, each of which a buyer shopping too early would recognise in themselves.
- Deliverability should be a component rather than an assumption. Send infrastructure is one of five published product areas with inbox warming the vendor operates, and the free email grader is a working diagnostic anyone can run without a sales conversation, which is a contribution to the discipline rather than a claim about it.

The short version of each
OptaReach
OptaReach is a multi channel outbound platform provided by Silyze that runs sequences of views, follows, connection requests, direct messages and generated replies across seven surfaces, with every reply landing in a shared inbox where a configurable agent drafts, reviews or sends according to rules the customer sets. The GTM Tech Index grades it A on commercial transparency, the only A on that axis in this sub lane, because every allowance a buyer will meet is published per tier and the charging rules are stated against the vendor's own interest, with reveals billed only on a verified new address and unused credits rolling over rather than expiring. The index grades it B on ecosystem and integration depth for a documented public interface with an authentication guide and endpoint reference, and D on platform terms exposure, data privacy posture, security certifications and exit and data portability.

Selix AI
Selix AI is an outbound agent from SellScale, Inc. that operates out of a team messaging channel rather than its own console, posting what it is researching and what it intends to do next, asking when it reaches a decision that benefits from human judgement, and surfacing proposed actions for review before anything executes. The GTM Tech Index grades it A on AI centrality and B on autonomy and oversight, recording that narration design as unusual because the operator sees intermediate steps rather than only the final artefact, and B on segment and market coverage for publishing three disqualifiers that cost the vendor pipeline. Against that it grades Selix D on commercial transparency, where the clearest statement available is a terms of service line saying fees will be communicated to the customer later, and D on AI disclosure, deployment and residency, and security certifications.

Common questions
Which of OptaReach and Selix AI publishes pricing?
OptaReach, by the widest margin on this axis in the sub lane. The GTM Tech Index grades it A on commercial transparency: three tiers from 59 dollars to just under 3,000, monthly, quarterly and annual terms with the discount stated as a percentage, and a seven line credit rate card with unit rates. Selix AI grades D. Its clearest pricing statement sits in its terms of service, which state that fees are set out in an order or will otherwise be communicated to the customer, and no tier, band, starting figure, unit of sale or trial term is published anywhere.
How much human oversight do OptaReach and Selix AI actually provide?
Both put it in a shared channel rather than a dashboard, which is unusual, and the mechanisms differ. Selix works out of a team messaging channel where the agent narrates its research, asks when it needs human judgement, and surfaces proposed actions before executing, so the operator sees intermediate steps rather than only the final artefact. OptaReach routes every reply across seven channels into one shared inbox where ownership is assigned, and its reply agent is configurable to draft, review or send with named guardrails and handoff rules. Neither enumerates which actions execute without approval or whether the gate can be disabled.
Do OptaReach or Selix AI disclose which AI model they use?
Neither names one. OptaReach generates campaigns, messages, replies, enrichment columns and public forum comments and prices each separately to two decimal places, while naming no base model, provider, family, version or hosting arrangement on any page, in the documentation, in the terms or in the privacy policy. Selix markets the product as a superintelligence and its privacy statement, which runs to considerable length on collection, lawful bases, transfers and retention, contains no section on model use at all. The GTM Tech Index grades OptaReach C and Selix D on that axis.
Where do OptaReach and Selix AI get contact data?
Neither publishes a source. OptaReach draws leads from searches run against six third party platforms, from tracked searches, from uploaded files and from what its documentation calls the vendor's own lead sources, which names a method rather than a supplier, and it sells verified email reveal at one credit per new address with no database, technique or lawful basis stated. Selix states only that it pulls contacts from leading data providers, and its own privacy statement separately confirms the company purchases data from lead generation providers and business intelligence platforms. Ask both which providers supply the records and on what basis they were collected.
Which platform carries more risk to my connected accounts?
OptaReach carries the broader surface and publishes no conformance position for any of it. It automates views, follows, connection requests, direct messages and generated replies across six networks and holds authenticated sessions for the customer's accounts on all of them, and the GTM Tech Index grades it D on platform terms exposure. Selix grades C: its agent operates through a team messaging platform's supported integration model, sending runs through the vendor's own infrastructure rather than borrowed accounts, and no account renting or undetectability marketing appears anywhere, though the vendor states which platforms its signal layer observes without stating how it obtains the data.
How does the GTM Tech Index grade OptaReach and Selix AI?
Both are graded on the same seventeen capability and compliance axes from public sources. Both take A on AI centrality and B on autonomy and oversight. The GTM Tech Index separates them on what a buyer can establish before contact: OptaReach holds A on commercial transparency and B on ecosystem and integration depth, against D and C for Selix. Selix holds B on deliverability discipline and B on segment and market coverage against C and B for OptaReach, and C on platform terms exposure and data privacy posture where OptaReach holds D on both. The index publishes no composite score and declares no winner.

Both vendors carry a gap on the instrument governing European contact, and they carry it differently. Selix AI's privacy statement contains a transfer section stating that the transatlantic privacy frameworks have been ruled invalid and that the vendor will continue protecting European data to their standards while replacement discussions proceed, linking to a government programme that no longer operates.
A replacement framework has been in force since 2023, so the document describing where European data may travel describes the regime as still pending. Standard contractual clauses are named elsewhere in the same statement, which is a current and valid mechanism, and the benign reading is that the section is stale rather than that anything improper is occurring. This index records what is published and asserts nothing about compliance either way.
OptaReach's gap is wider and differently shaped. Its privacy policy is written entirely about the subscriber, covering the account holder's name, payment details, usage statistics and device information, and says nothing about the people the product exists to process, while the page metadata for that same document lists four privacy regimes the text itself never mentions. The shared silence is supply.
Neither vendor names a single contact data provider, and both build targeting on behavioural observation of named individuals across platforms they do not own, Selix through champion tracking and professional network monitoring, OptaReach through tracked searches across six networks.
One further property of the published record itself is worth a buyer's attention: Selix's product and customer pages render entirely client side and return only metadata to any client that does not execute scripts, so a buyer researching through an AI assistant reaches the legal documents and none of the product.
