The short answer
Our database lists 353 startup investors in Illinois focused on b2b saas & enterprise software — 34% of the 1,033 startup investors we list in the state. Most are in Chicago (316). (Zalarma investor database, as of 2026-11-01.)
What these investors look for
- Show the motion, not just the product: who buys, how they find you, how long a deal takes and what a customer pays in year one.
- At pre-seed, design partners and paid pilots beat vanity sign-ups. Three customers paying anything is a stronger story than 300 free accounts.
- Vertical software for a local industry (logistics, construction, insurance, manufacturing) is a strength outside Silicon Valley: you are closer to the buyer than most competitors.

About this data
Counts are records in the Zalarma investor database, as of 2026-11-01: angels, venture firms and their partners, micro-VCs, family offices, corporate VCs and accelerators that list startup investing. One investor can appear in several stage or sector rows. Stage, sector and check size come from what each record lists, so not every record has every field. Counts under 10 are not shown. Firm names are listed; we do not publish personal contact details on this site. Read how we build and check the data.
