Hi, I'm Tihon.

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.

“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”

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.

How a concentrated market looks like: in an illustrative market of 100,000 companies, the top 10 companies take 50% of global revenue, the next 90 take 30%, and everyone else shares 20%.How a concentratedmarket looks likeILLUSTRATIVE MARKET · 100,000 COMPANIESSmallercompaniesLong-tailcompaniesTop 10 companies50%of global revenueNext 90 companies30%of global revenueEveryone else20%of global revenueArea = company count · Lower two tiers are illustrative

In these markets, focus, credibility and relationships matter more than volume.

Frequently asked questions

What is finite market GTM?

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.
