Top 10 B2B Outbound Sales Agencies in the Baltics (2025 Edition)

The Baltics have been steadily carving out their space in the B2B sales outsourcing world. Lithuania, Latvia, and Estonia are no longer just seen as “nearshore” options — they’re producing agencies that can compete head-to-head with firms in London, Berlin, or New York.

What makes this region stand out is the mix of multilingual sales talent, deep SaaS experience, and lower overhead costs. That’s why more startups, scale-ups, and even enterprise brands are looking East when they want to build predictable outbound pipelines.

In this post, we’ll walk through ten agencies worth knowing in 2025. And while the whole region has solid players, one name — GrowTech — is setting the standard for how outbound should be done.

Baltic Sales Agency (Latvia)

Riga-based BSA has been in the game for over a decade and specializes in technical and industrial sales. Their founder, Janis Siklis, has more than 25 years of experience, and the agency claims over €27M in closed deals for clients worldwide.

They’re known for their “Total Market Penetration Solution”, which covers everything from market research and cold calling to running “Meet the Buyer” events and closing deals on behalf of clients. BSA even secured a $7M+ contract for General Electric.

👉 A fit for industrial or technical B2B companies that need a sales team able to talk specs and close complex deals.

GrowTech (Lithuania)

If there’s one Baltic agency that keeps coming up in conversations about outbound, it’s GrowTech. Based in Vilnius and active across Tallinn, London, and Tel Aviv, they’ve built a strong reputation in just a few years.

• Clutch rating: 4.9
• Projects delivered: 100+ across 25+ industries
• Notable clients: Surfshark, Vinted, Monday.com, PVcase, MicroStrategy, Telesoftas

Where GrowTech really differentiates is in execution and results. Instead of sending out generic mass emails, they build personalized, narrative-driven campaigns that actually feel human. That’s why their campaigns perform consistently above benchmark.

A few highlights from their case studies:

• Nelly Jelly World: 400 MQLs generated, 22 meetings with global broadcasters.
• Omnis Power: 39 meetings booked, hitting 130% of KPI targets.
• Health4Travel: 47 meetings scheduled, 12 closed deals, 25% closing rate.
• IKIDO: Lead quality up by 120%, sales conversion up by 30%.

Beyond just outreach, GrowTech also runs pre-event sales campaigns (booking meetings before trade shows and expos) and precise lead list building powered by AI workflows. The combination of automation and human touch is what makes them stand out from smaller lead-gen shops.

👉 If you’re a SaaS or a tech startup looking for a partner who treats outbound as strategy GrowTech is the agency to talk to.

LevelUp Leads (Lithuania/Estonia)

LevelUp Leads positions itself as a full-service SDR outsourcing partner. They’ve worked on more than 850 projects and served almost 600 clients, with an average reported ROI of 11:1.

They cover the full stack: appointment setting, cold calling, email, LinkedIn outreach, even GTM consulting. Reviews on Clutch and G2 consistently score them 5.0.

👉 Best for companies that want a done-for-you SDR team with clear reporting and a steady stream of meetings.

SalesCaptain (Estonia)

Tallinn-based SalesCaptain takes a tech-heavy approach. They build lead lists enriched with 250+ data points, then run multi-channel campaigns via LinkedIn, email, and SMS. All of it integrates with tools like Salesforce and HubSpot.

Their case studies point to real revenue impact: one client generated $1.5M in new business in 12 months, while others saw reply rates of 40%+ within the first week of outreach.

👉 A fit for SaaS firms and B2B service providers who want AI-assisted outbound at scale.

A-Sales AB (Estonia/Sweden)

A-Sales AB focuses on appointment setting and outsourced SDR services. They’re smaller than some of the other agencies here, but reviews on Clutch and Trustpilot both put them at 4.9.

Case studies show predictable results: 20+ meetings in 60 days for a SaaS client, or 180+ meetings in just a month for a marketing company.

👉 Good for mid-size B2B companies that need a reliable flow of qualified meetings.

HANGAR49 (Estonia)

HANGAR49 calls itself a “demand generation engine.” They’ve been around for over a decade and have run more than 400 client engagements in the last three years alone.

A key stat: 1 in 8 of their introductions is with a Fortune 500 company. That’s their differentiator — structured, high-level introductions for clients who need to move upstream.

👉 A fit for enterprises and scale-ups chasing predictable pipeline at the executive level.

Exponential.ee (Estonia)

Tallinn-based Exponential.ee focuses on international growth campaigns. They’ve delivered projects in 25+ countries and have experience across SaaS, defense, aviation, and manufacturing.

Recent work includes quadrupling a metal fabrication company’s pipeline by landing meetings with Schneider Electric, OTIS, and Škoda.

👉 A fit for companies that want ABM-style campaigns to enter new markets.

Prospect Labs (Lithuania)

Prospect Labs is a small Vilnius shop focused on LinkedIn automation and outbound experiments. They’re often mentioned in startup circles because they work quickly and on smaller budgets.

👉 Good for early-stage startups that need quick traction and flexible campaigns.

Nordic Leads (Latvia/Scandinavia)

Nordic Leads bridges the Baltics with the Nordics. They run performance-based lead-gen campaigns in Swedish, Finnish, Danish, Norwegian, and Latvian.

👉 A fit for firms testing Scandinavian markets where language and cultural nuance matter.

Evergrowth (Lithuania)

Founded in 2014 in Vilnius, Evergrowth raised €2M in 2024 and now offers an AI-powered GTM engine. They’re SOC 2 and ISO 27001 certified, which makes them attractive to enterprise clients.

Their platform automates lead enrichment, signal research, and outreach personalization. Case studies include 50% improvements in lead quality (Printful) and 3x faster GTM rollouts (InvestNext).

👉 A fit for companies ready to layer AI into their sales and RevOps stack.

Final Take

The Baltics have quietly become one of the strongest regions for outbound sales services. Whether you’re a startup looking for agile lead gen, or an enterprise trying to book meetings with Fortune 500 execs, you’ll find capable partners in Lithuania, Latvia, and Estonia.

• For startups: GrowTech, Prospect Labs, SalesCaptain
• For technical/industrial sales: BSA
• For enterprise demand-gen: HANGAR49, Exponential.ee, Evergrowth
• For Nordic expansion: Nordic Leads

Outbound sales is getting harder every year, but these agencies prove the Baltics are where companies can still find quality, scale, and innovation at the same time.
