I help founders of complex B2B startups build repeatable GTM and earn trust with the buyers who matter.
I turn founder knowledge into practical GTM systems and original content that helps reach the right customers.
A finite market is a market where the realistic buyer universe can be identified and counted. For the complex B2B startups I work with, that is often around 200-1,000 realistic buyers.
“In one month with Tihon we achieved more than with an agency over half a year.”

“Tihon helped us get clients from a market we couldn't reach before - and two of these companies we signed are unicorns. We got 2-4 good opportunities every month.”

“Our previous agency focused on getting more clicks from LinkedIn ads. Tihon helped us see that we were attracting the wrong attention and potentially hurting our reputation. We changed our approach, focused on the right audience, and started getting inbound interest from companies that actually mattered to us”

“I had the pleasure of working with Tihon on sales and campaign launches. He is responsible, polite, and a great team player. I’ve always appreciated his agile thinking and proactive approach.”

Who this is for
Complex B2B startups selling into finite and concentrated markets.
Companies with real customers, high-value deals, long sales cycles and a relatively small number of important buyers.
Sometimes there are only 100, 500 or 2,000 realistic accounts.
Sometimes the market is larger, but 20–50 companies control most of the revenue.
In these markets, focus, credibility and relationships matter more than volume.
About me
Tihon Erofeenko
15+ years across B2B sales and marketing, from personally closing deals to building teams and commercial growth systems.
Today I work directly with founders of complex B2B companies, helping them make their GTM more repeatable and become better known among their most important potential buyers.
Finite Markets Lab
Conversations with people who actually build in these markets.
I host Finite Markets Lab, where founders and practitioners share what worked, what failed and how they win complex B2B deals.
Why founder-led GTM gets stuck
Christopher Engman, author of Megadeals, and I discussed why even experienced B2B companies struggle to scale beyond founder-led sales.
Finite market GTM focuses on a countable group of realistic buyers, rather than treating every account like another lead. Account prioritisation, credibility and relationships matter because important buyers are difficult to replace.
Who is the GTM sprint for?
The 30-day GTM sprint is for founders of complex B2B startups with real customers, high-value deals and long sales cycles in finite or concentrated markets. It helps turn founder knowledge into a GTM system the team can repeat.
What is the Founder authority engine?
The Founder authority engine turns a founder's expertise into original LinkedIn videos and written posts, with contact research and relationship-building guidance. Each month includes 4 video shorts, 4 text posts, 20 handpicked contacts, one recorded interview and one strategy call.
How is working with Tihon different from a typical GTM agency?
You work directly with me across sales, marketing and account strategy, rather than starting with a fixed channel or a standard playbook. The work starts with your real deals, market and founder knowledge.
What results can founders expect, and in what timeframe?
The sprint runs for 30 days and delivers GTM analysis, architecture, a practical playbook, a team handoff and a 90-day plan. The authority engine delivers content and relationship-building guidance monthly; these are deliverables, not a promise of a specific number of sales or a sales timeline.
