Fintech Series A Investors 2026: Who's Writing Checks, Who's Quiet

A founder I spoke with last week pitched 19 fintech VCs in March. Twelve said they were "actively deploying in Series A fintech." When we filtered their last 90 days of actual investments, four had written checks. One had moved upstream to growth rounds only. Seven hadn't closed a fintech deal since Q2 2024.

This is the 2026 fintech Series A market. Not dead, but dishonest. Firms that raised Fund IV in 2021 are still showing up on "active investor" lists, still taking meetings, still asking for decks. But the capital is spoken for, the mandate has shifted, or the check size now starts at $15M instead of $8M.

If you are raising a fintech Series A right now, your investor list is probably 40% wrong. Here is who is actually writing checks, who has gone quiet, and who is wasting your time.

Who is actually writing Series A fintech checks in 2026

Let's start with the truth: there are fewer Series A fintech buyers today than there were 18 months ago. But the ones still in the market are writing bigger checks, faster.

The funds that closed capital in 2024-2025 and are deploying now

Firms that raised new funds between mid-2024 and early 2025 are the cleanest signal. They have unallocated capital, fresh LPs expecting deployment velocity, and partnership consensus on thesis.

Bain Capital Ventures closed Fund XIV ($1.65B) in October 2024. They have written three fintech Series A checks since January 2026, all in the $10M to $14M range. Thesis skews toward vertical SaaS with embedded finance, not pure consumer fintech.

Ribbit Capital raised $600M in late 2024 and has been aggressively active. Four Series A deals in fintech since December, including two in Latin America. If you are building infrastructure (core banking, compliance automation, payments middleware), Ribbit is still taking cold intros.

QED Investors is the most consistent name on this list. They wrote six fintech Series A checks in Q1 2026 alone. Check sizes range from $8M to $18M. They are thesis-driven, but if your metrics are clean and you are solving a regulated pain point, they move fast.

Portage Ventures (Canada-based, global reach) closed their third fund in early 2025 and has deployed into five fintech Series A rounds since. Bias toward B2B fintech, especially anything touching SMB cash flow or AR/AP.

Nyca Partners is still active but selective. Two Series A deals in the last six months, both in insurtech and regtech. If you are pure payments or neobank-adjacent, Nyca is probably not the fit anymore.

The crossover firms that quietly started writing earlier checks

A surprising shift: some growth-stage firms that sat out Series A from 2022 to 2024 have started writing $12M to $20M A rounds again, but only for companies that look like B rounds.

Coatue wrote two fintech Series A checks in Q4 2025. Both companies had $8M+ ARR and were technically Series A by count, but priced like growth rounds. If you are sub-$3M ARR, Coatue is not your call.

Insight Partners has done something similar. One Series A in fintech (payments infrastructure, $15M round, $6M ARR at close). The bar is higher, but they are in the market.

This changes your targeting strategy. If your metrics are strong enough to attract a crossover fund writing a Series A check, you are probably underpricing your round. Run the numbers at B-round comparables before you set the term sheet.

Who has gone quiet (and will not tell you)

This is the harder list to get right, because these firms still show up on Crunchbase as "active," still attend demo days, still respond to cold emails. But they are not writing checks.

Firms that moved upstream to Series B and later

Andreessen Horowitz (a16z) fintech practice wrote zero Series A checks in the last 12 months. Their last fintech A was in Q1 2024. They are now entering at Series B or later, $20M+ checks only. If you are raising an A, a16z is a distraction.

General Catalyst has done the same. Their fintech team is focused on growth rounds and expansion-stage companies. Last Series A: August 2024. They will still take the meeting, though. Do not let them.

Index Ventures (US side) has not led a fintech Series A since late 2023. They are still active in fintech, but the entry point has shifted to B and C. Their European team is slightly more active at A, but check sizes are smaller (€6M to €10M range).

Firms that quietly stopped deploying (but have not announced it)

Some funds raised capital in 2020-2021, deployed aggressively through 2022, and are now in portfolio management mode. They are not fundraising yet, so there is no public signal. But the capital is gone.

Fin Ventures last wrote a Series A check in February 2025. Since then, they have done three follow-ons and no new deals. The fund is not closed, but deployment has slowed to near-zero. If you are building a target list and Fin Ventures is on it, call someone who raised from them recently and ask directly.

Commerce Ventures wrote four fintech Series A deals in 2023, two in 2024, and zero in 2025-2026 so far. They are still listed as "actively investing" on their site. They are not.

Pivot Investment Partners has shifted focus almost entirely to growth equity. Last Series A: June 2024. They are still fielding decks, still doing diligence calls, but nothing is closing.

Here is the pattern: if a fund's last fintech Series A deal was more than 14 months ago and they have done follow-ons but no new deals since, they are probably out of the market. Check our investor directory and filter by "last fintech investment date" to avoid this trap.

Who is pretending (and how to spot them fast)

This is the most expensive category. Firms that are not deploying, know they are not deploying, but still take meetings because they want optionality, deal flow for Fund V, or board seats in companies that are oversubscribed.

They will waste 60 to 90 days of your raise.

The tells

They ask for a deck but will not commit to a partner meeting date. Real buyers move fast. If you send a deck on Monday and do not have a meeting scheduled by Friday, they are either backlogged (unlikely in 2026) or not serious.

They do multiple diligence calls but will not name a decision timeline. This is the worst one. You will do two calls, a financial deep dive, a product demo, and a reference check, and then they will say "we are still building conviction." Translation: they are not writing the check, but they want to stay warm in case you get a term sheet from someone else.

Their last three investments were follow-ons, not new deals. Go to their portfolio page. If every "recent investment" is a Series B or C in a company they backed at seed, they are in preserve mode, not deploy mode.

They ask if you have other term sheets before they commit to moving forward. Real buyers do their own work. Tourists wait to see if someone else says yes first.

How to filter them out: Before you take the first meeting, ask one question via email: "What was the last fintech Series A you led, and when did it close?" If they will not answer, or if the answer is more than 12 months ago, skip the meeting. Your time is the scarcest resource in a raise.

The new players (who most founders miss)

A handful of firms have launched fintech-focused practices or raised debut funds in the last 18 months. They are hungry, they have capital to deploy, and they are under-targeted.

Step Ventures launched in mid-2024 with a $120M debut fund focused on fintech infrastructure. They have written four Series A checks since launch, all in the $6M to $10M range. Thesis is narrow (B2B fintech SaaS, compliance automation, embedded banking), but if you fit, they are one of the fastest movers in the market.

Unshackled Ventures is not new, but their fintech allocation has doubled in the last year. They wrote three Series A deals in 2025, all immigrant-founded fintech companies. If that is your profile, they are worth the call.

Fika Ventures (LA-based) has quietly become one of the most consistent fintech Series A writers on the West Coast. Five deals since mid-2024, check sizes in the $7M to $12M range. Bias toward SaaS with fintech components rather than pure fintech plays.

These firms do not show up on most target lists yet. If you are using a static database or a Crunchbase export from six months ago, you are missing them. Run a fresh filter here to catch funds that have closed in the last 12 months.

How to build a real list (not a hopeful one)

Most founders build their Series A investor list by Googling "top fintech VCs" or exporting a Crunchbase filter. That list is 18 months stale the moment you make it.

Here is a better approach:

1. Filter by last investment date, not AUM. A $2B fund that has not written a fintech Series A check in 14 months is worth less than a $150M fund that wrote three in the last six months.

2. Check the fund vintage. If a firm raised their current fund in 2021 or earlier, they are probably in the back half of deployment (or done). Look for funds closed in 2024 or 2025.

3. Map check size to your actual round size. If you are raising $8M and a firm's last three Series A checks were $18M, $22M, and $15M, you are too small. Do not pitch them.

4. Prioritize firms that have written multiple fintech checks in the last 12 months. One deal could be an outlier. Three deals is a pattern. Five deals is a mandate.

5. Call a founder who closed a Series A in the last 90 days and ask who else was serious. Not who took meetings. Who moved to term sheet diligence. That is your real list.

The median fintech Series A founder pitches 38 investors. If your list is longer than 50, you probably have not filtered hard enough. If it is shorter than 25, you are underbanked on backups. The right range is 30 to 45 names, ruthlessly filtered.

What changed between 2024 and 2026 (and what it means for your deck)

The fintech Series A market is not just smaller. It is also slower and more diligence-heavy.

In 2021, a fintech company with $2M ARR and 15% month-over-month growth could close a Series A in six weeks. In 2026, that same company will take four months and will need to show unit economics, CAC payback under 18 months, and a path to default alive.

The decks that are closing rounds now have three things in common:

1. A specific wedge, not a platform vision. "We are building the operating system for SMB finance" is a 2021 pitch. "We automate sales tax compliance for e-commerce brands using state API integrations" is a 2026 pitch.

2. Customer concentration data upfront. If your top 10 customers are 60% of revenue, investors will find out. Show it in the deck, explain the plan to diversify, and de-risk it before they ask.

3. A boring, profitable customer acquisition channel. Virality and product-led growth are great, but fintech buyers in 2026 want to see that you can profitably buy customers through Google, outbound, or partnerships. Show CAC, LTV, and payback period on page 8 or earlier.

If your deck does not have these, you will get to second meetings but not to term sheets. Score your deck here to see what is missing before you start pitching.

The 2026 fintech Series A round, by the numbers

Among the founders I have worked with who closed fintech Series A rounds in the last six months:

• Median round size: $11M (up from $8M in 2024, but fewer rounds overall)
• Median time to close: 16 weeks (up from 11 weeks in 2024)
• Median number of partners pitched: 34
• Median number of term sheets received: 1.4 (most rounds are not competitive anymore)
• Median post-money valuation: $52M (down from $78M in 2024)

The punchline: fewer buyers, slower process, lower prices. If you are raising in 2026, your job is not to find 100 investors. It is to find the 8 to 12 who are actually writing checks, and to make sure your deck and your metrics are sharp enough to close one of them.

If your raise is stuck because your investor list is stale or your targeting is off, upload your deck here and filter to firms that match your stage, check size, and thesis. It takes 30 seconds and it might save you two months of dead-end pitches.
