Five Boom Years Built 41% of Thailand's Company Register in 2026
In short
Forty one point two percent of every Thai company with a known founding year was registered in just five calendar years, all of them since 2019. Thailand's registry holds 1,561,866 companies with a dated founding year across 19 years, from 2007 to 2025. The five busiest years, 2021, 2025, 2020, 2024 and 2022, added 643,829 new companies between them. The other fourteen years produced the remaining 58.8 percent. Registration did not climb steadily, it surged.
Do boom years dominate Thailand's company register?
Yes, decisively. Forty one point two percent of every Thai company with a known founding year was registered in just five calendar years. The registry carries 1,561,866 companies with a dated founding year, spread across 19 years from 2007 to 2025 (DBD, 2026). Five of those years, 2021, 2025, 2020, 2024 and 2022, produced 643,829 of them. Every one of the five falls in 2019 or later, none earlier. The other 14 years produced the remaining 58.8 percent, but each of those years averaged only 65,574 new companies against 128,766 in an average boom year. A boom year outproduces an ordinary year by nearly two to one.

New companies registered by founding year, ranked, against the 19 year total of 1,561,866, as of 7 Jul 2026.
Why the concentration matters
Concentration on this scale changes how the whole register should be read. Any survival rate or vintage study built on the full 1,561,866 company population is quietly dominated by cohorts that are barely a few years old. A company founded in 2021 has had far less time to fail, merge or go dormant than one founded in 2010, so averaging all 19 years into one survival figure flatters the register. Four of the five busiest years on record, 2021, 2025, 2024 and 2020, sit inside the last five years alone. That means the register's age structure, its industry mix and its provincial mix are all being reshaped right now by companies that have barely had a chance to prove themselves. Anyone comparing today's company count against an earlier benchmark year should first check which vintage of company they are actually counting.
Definitions
- Dated company
- A company in the registry whose founding year is known and recorded, as opposed to one with a missing or unrecorded founding year.
- Boom year
- One of the five founding years, out of the 19 measured, with the highest count of new company registrations.
- Partial year
- The current calendar year, 2026, which is still in progress at the time of measurement and therefore not comparable to a completed year.
- Founding year
- The calendar year in which a company was first registered with the Department of Business Development, used here in the Gregorian calendar.
Assumptions
- The 19 year total of 1,561,866 covers only founding years 2007 through 2025 as recorded in market_new_companies_insight, and does not represent Thailand's full registered company count of 1,989,709, since companies founded before 2007 or with no recorded founding year fall outside this table.
- 2026 is excluded from every total and share because it is a partial year still being recorded.
- Counts are registration events by founding year and are not adjusted for companies that later dissolved, merged or went dormant.
- The five boom years were selected purely by ranking new company counts and carry no claim about what caused the increase.
Methodology
New company counts by founding year are drawn from the DBD registry as aggregated in market_new_companies_insight, as of 7 July 2026. The 19 year window covers founding years 2007 through 2025. The current year, 2026, is a partial year with 110,866 companies recorded so far and is excluded from every total and share in this analysis so the comparison is not distorted by an unfinished year. Founding year reflects each company's registration date, not its size or industry. The five boom years were identified by ranking the 19 dated years by new company count and taking the five highest. Figures are counts of registration events and are not adjusted for later dissolution or amalgamation.
How we verified this
- Summed new_companies across founding years 2007 to 2025 in market_new_companies_insight: 30,227 plus 33,093 plus 35,371 plus 41,404 plus 45,389 plus 49,466 plus 60,270 plus 63,417 plus 68,500 plus 73,163 plus 89,719 plus 104,273 plus 111,284 plus 122,427 plus 151,205 plus 119,923 plus 112,461 plus 121,657 plus 128,617 equals 1,561,866, the 19 year denominator.
- Ranked all 19 dated years by new_companies and took the top five: 2021 at 151,205, 2025 at 128,617, 2020 at 122,427, 2024 at 121,657 and 2022 at 119,923, summing to 643,829, and confirmed all five fall in 2019 or later.
- Recomputed the boom year share as 643,829 divided by 1,561,866, which equals 0.4122, or 41.2 percent.
- Recomputed the remaining 14 years as 1,561,866 minus 643,829 equals 918,037, or 58.8 percent, and confirmed 41.2 plus 58.8 sums to 100.
- Recomputed the per year averages as 918,037 divided by 14 equals 65,574 for an ordinary year and 643,829 divided by 5 equals 128,766 for a boom year, a ratio of 1.96.
