About LocalVein

An intelligence layer for agency prospecting —
built for operators, by operators.

LocalVein composites 19 prospect signals into a single 0–100 opportunity score so agency outbound stops burning hours on dead leads. Live carrier line-typing on every phone, DNC pre-scrub on every row, weekly re-checking on the prospects you watchlist. Used by agencies running outbound across 28 verticals and every US state.

We don’t send the email. We don’t replace your CRM. We feed the stack you already pay for — GoHighLevel, HubSpot, Instantly, Smartlead — with cleaner data than they could otherwise see.

The build economics

$50K+ to build. Four engineers to maintain. $179/mo to subscribe.

The scrape is the cheap 10%. The hard 90% is composing demographic spend power, line-type detection, DNC status, site staleness, domain age, ad-pixel decay, and competitor density into a single opportunity score — then re-checking all of it weekly so your pipeline doesn’t go stale. Buying the capability outright runs six figures of engineering plus a renewable data stack. Subscribing is the rational time-arbitrage if your agency revenue is anywhere past five figures monthly.

Who’s behind this

Mateo Briosso — founder, signs every email

I run LocalVein and also Titan Pipelines, a trades-vertical marketing agency in the same neighborhood as the agencies LocalVein serves. The Titan dataset is what taught me which signals actually predict a closed deal versus which ones just look smart on a dashboard — vulnerability scoring, line-type tagging, DNC pre-scrub, contact email, site staleness — and LocalVein is that scoring layer broken out of a single agency’s tooling and made into something any agency can subscribe to.

I don’t do LinkedIn theatre, a founder podcast, or X threads — the bandwidth goes into the product instead. Every cold email, lifecycle email, and support reply you get from @localvein.com(or any of the secondary domains we send from) is signed by me. If something’s wrong with the product or the way I reached out, reply to the email and you’ll get me directly.

Reach: mateo@localvein.com or reply to any thread we’re already on.

What this company isn’t

Discipline list (the long version)

Most agency-prospecting tools drift into outreach, then into CRM, then into “all-in-one.” LocalVein doesn’t. The discipline:

  • No email outreach. Use the tool you trust — Instantly, Smartlead, GHL — and we feed it.
  • No email warmup, sender rotation, or inbox. That’s a different product with different incentives.
  • No decision-maker LinkedIn scraping. We score businesses, not people.
  • No expansion to corporate B2B. Local services is the lane.
  • No public business pages. We don’t expose individual prospect data on a public URL.

When prospects ask why we don’t bundle outreach: because Instantly is better at outreach than we’d be in our first three years, and because the moment we ship a sender, we start optimizing for inbox metrics instead of close-rate. We stay middleware on purpose.
