Series A Investors: 5 Firms With New Funds in October 2026, Ranked by Filed Amount

Series A investors are the firms that lead a company's first large institutional round, usually after a seed round and some early traction. This list ranks five Series A investors that filed new vehicles between late September and October 23, 2026, ordered by the amount each vehicle reported. We kept only firms whose stage focus we could confirm from public sources, so several larger filings were left out because we could not verify what they back. For each firm, we say what is confirmed and what is not.

How to Read the Ranking

A filing shows that a vehicle exists and how much it reports as sold. It does not show a final close or a stage focus. The amounts below are as filed, and a named vehicle may be a side fund or a single-deal vehicle, not the firm's main fund. Check each firm's own announcements before you pitch.

1. Swish Ventures: $216.6 Million Filed for Swish Ventures Early II

Swish Ventures, led by former NBA player Omri Casspi, filed Swish Ventures Early II at $216.6 million on October 7. It began in December 2024 with a $60 million seed fund for cybersecurity, cloud infrastructure and AI startups. Globes later reported that Swish closed a $250 million third fund, bringing assets under management to about $800 million, with a focus on seed and Series A plus an opportunity fund for follow-ons. We could not match the filed vehicle to a specific announced fund, so treat the amount as a filing figure. Swish is a fit if you build in security, cloud or AI infrastructure and want a lead for a Series A.

2. 7wire Ventures: $111.0 Million Filed for Fund III

7wire Ventures, co-founded by Glen Tullman and Lee Shapiro, filed Fund III at $111.0 million on October 15. The Chicago firm invests in early-stage healthcare technology, with a thesis built around the connected health consumer. Its earlier funds include a $150 million fund in 2021 and a $217 million growth and opportunity fund. Its first investor position in Livongo led to that company's merger with Teladoc, and its portfolio includes NOCD and FOLX Health. We could not confirm the size or vintage of Fund III outside the filing, and a third-party listing describes a "Core Fund III" for seed and Series A deployment. It is a fit for consumer-facing health software.

3. Fin Capital: $80.0 Million Filed for Flagship III

Fin Capital, founded by Logan Allin, a former SoFi Ventures executive, filed Fin Capital Flagship III - SBIC at $80.0 million on October 23. The firm describes four strategies: Regatta for pre-seed, Flagship for early stage, Horizons for growth and Constellation for public equity. Flagship is the early-stage strategy, so this vehicle is the one for companies raising a Series A. The firm covers embedded finance, asset management, CFO tools, insurtech, blockchain and enabling infrastructure. We found no public detail on the SBIC structure, which usually refers to a Small Business Investment Company licensed in the US. It is a fit for fintech founders.

4. Redpoint Ventures: $53.4 Million Filed for IX-M

Redpoint Ventures filed Redpoint Ventures IX-M at $53.4 million on October 15. Redpoint's early-stage funds focus on seed through Series B, according to a 2022 Cooley release on its ninth early-stage fund, a $650 million vehicle. TechCrunch reported at the time that checks would range from $2 million to $15 million. A profile site says a tenth early-stage fund of $650 million closed in May 2025, though we could not verify it. We found no public explanation of what IX-M is, so the amount should be read as a filing figure. Redpoint is a broad early-stage firm, so it suits many sectors.

5. Costanoa Ventures: $275 Million Fifth Fund and a New LA Early Vehicle

Costanoa Ventures, founded in 2012 by Greg Sands, is a seed and Series A firm focused on enterprise software, fintech, AI and security, according to Cooley. It closed its fifth early-stage fund at $275 million and a nearly $120 million third opportunity fund in September 2024. The firm filed a new vehicle called Costanoa LA Early at $50 million on September 30. Check sizes vary by source, and the most consistent ranges put an early check between $2 million and $8 million. It is a fit for enterprise and fintech founders with early revenue.

What Series A Investors Look For

Series A investors want proof that the product works and can grow. They look for repeatable sales, retention that stays steady and a clear way to reach the next stage of growth. Revenue targets vary by sector, so ask each firm what it expects. Be ready to show how you will use the money over 18 to 24 months.

How to Approach Them

Get a warm introduction from a seed investor, a founder in the portfolio or a lawyer. Your first message should say what you build, your traction, your growth rate and how much you are raising. Prepare your data room and understand your cap table and dilution before the first call. Ask whether the firm expects to be the lead investor on your Series A and what its term sheet usually includes.

What to Watch Next

Watch whether Swish, 7wire and Redpoint announce details of their new vehicles. We refresh this list monthly.
