Northern Dealbook is an independent record of private equity and venture capital in Minnesota, Wisconsin, and the Dakotas — who is investing, what they are buying, and what it means for the founders and fund managers on the other side of the table.
The capital figure sums disclosed amounts only. As of this build all 274 recorded transactions disclosed one, so it covers the whole record; a transaction that discloses no amount is excluded rather than counted as zero.

Regional capital is badly documented. National databases treat the Upper Midwest as a rounding error, the trade press covers the handful of rounds large enough to make a headline, and the filings that record the rest sit in EDGAR where nobody reads them. The result is that a founder in Fargo and a fund manager in Milwaukee are both working from an incomplete map.
This is the map. Every firm profile and every transaction here carries a citation on the page, and where a number was not disclosed the field is left off rather than estimated.
What this is
132 private equity, venture, growth and credit firms deploying capital in the four states. Filter by state, strategy, stage and check size; every profile shows its sources and the date it was last verified.

Coverage
Firms are counted by the states they say they invest in, so a fund active in three of them appears in three columns; transactions are counted by where the company sits, so those totals are disjoint and add to the record.
Composition

Firms by strategy
| Strategy | Firms |
|---|---|
| Private Equity | 82 |
| Venture Capital | 53 |
Transactions by type
| Type | Deals |
|---|---|
| Exempt offering | 235 |
| Debt financing | 36 |
| Venture round | 2 |
| Fund close | 1 |
A firm running two strategies is counted under both, so the strategy column sums above 132. Transaction types are mutually exclusive and sum to 274.
Scale
Disclosed only. Every transaction on the record currently reports an amount, so this is the whole ranking — but a deal that closes without disclosing will never appear here however large it was.

The statute sunset for tax years beginning after December 31, 2024. The Department of Revenue's guidance page, updated in December 2025, carries no expiration notice. Here is what actually survives.
Minn. Stat. § 181.988 makes employee non-competes void, blocks the choice-of-law workaround, and awards fees to employees. The sale-of-business exception survives intact. For a buyer, that combination changes what you are actually acquiring.
A 45 percent seed capital credit and a 35 percent angel fund credit make North Dakota the most generous of the four states for early-stage investors — by a wide margin, and with the smallest economy behind it.
Section 1202 got its biggest expansion in fifteen years: a tiered holding period, a $15 million cap, and a $75 million asset test. But the list of businesses that cannot qualify maps uncomfortably well onto the Upper Midwest economy.
