Your analyst
never sleeps.

Arca monitors private market signals around the clock. Funding events, hiring velocity, market entry — it watches everything and tells you what matters.

What Arca watches

Six signal channels, running continuously. Nothing slips through.

Funding Events
Round sizes, lead investors, valuation caps. Surface companies raising before the press release.
Team Velocity
Hiring surges, executive departures, co-founder moves. Detect company momentum shifts before they show in the metrics.
Product Momentum
GitHub activity, web traffic growth, feature launches. Quantify what the market is responding to.
Market Presence
Domain registrations, trademark filings, press mentions. Catch new entrants building in your thesis areas.
Tech Stack Signals
Infrastructure decisions, API integrations, engineering hiring. Know what a company is building before they pitch.
Competitive Landscape
Funding rounds in your sector, co-investor activity, adjacent market entries. Know where capital is flowing.
How it works

One analyst. Multiple signals. Zero noise.

Most deal flow tools make you query them. Arca works the other way around — it watches your market continuously and pushes relevant signals to you. You set the thesis. Arca finds the companies that match it.

01
Define your thesis
Describe the companies you're looking for — sector, stage, geography, signal type. Arca learns your criteria.
02
Arca monitors continuously
Across six signal channels, across the market. Every company that fits your thesis gets tracked automatically.
03
Signals surface to you
When a tracked company hits a milestone — a new hire, a funding event, a product launch — Arca flags it and scores it against your criteria.

The gap

The best deals don't wait for you to look.

6–8
weeks — the typical lag between a funding signal and its appearance in databases like PitchBook or CB Insights. By then, the round is often closed.
73%
of meaningful company signals are buried in public data — job postings, domain registrations, GitHub activity — invisible to anyone not actively watching.
4 hrs
per day — the average time a growth equity investor spends on manual research and deal monitoring. Arca replaces that hours-long block entirely.

The firms that win aren't the ones with the biggest analyst team. They're the ones that see the signal first.

"You don't need another database. You need someone watching the market while you sleep."

Every growth equity firm has the same problem: too much market, not enough time. The companies worth watching are moving constantly. By the time a pitch lands in your inbox, the moment has often passed.

Arca is built for the investor who wants to move first. Not first to respond to a deal — first to know it exists.
