Companies that raised in the first week of September

A funding round is the loudest public signal a company sends. It is dated, it is public, and it usually means a planning cycle just restarted. The part that gets lost in most funding lists is the date. A round that closed a year ago reads exactly like one announced yesterday once it has been copied into a feed, and by then the budget is assigned and the shortlists are formed.

So every entry below carries the lead investor, because it tells you something about the round's shape, and the announcement date, linked to the source that carried it. If a date here looks stale to you, that is the point. You can check it in one click rather than taking anyone's word for it.

Five US B2B companies announced funding between August 31 and September 5.

Gimlet Labs, San Francisco

Gimlet Labs raised a $300M Series B led by Andreessen Horowitz at a $3 billion valuation, announced September 4. It calls itself an applied AI research and product company and describes its product as a multi-silicon inference cloud for agentic AI, which runs each phase of an AI workload on whichever chip suits it best.

The release says the money goes to building out operations for that cloud and to expanding the team. Both are the kind of spend that shows up as new roles before it shows up anywhere else.

Lyte, Sunnyvale

Lyte raised a $165M Series C led by Maverick Silicon at a $1.6 billion valuation, announced September 2. The company designs custom silicon, multimodal sensors and spatial software that robots use to sense where they are and what is moving around them, a stack it owns from the transistor upward.

A company shipping its own silicon and sensors at this stage is scaling manufacturing and supply chain, not just software.

TabaPay, Palo Alto

TabaPay closed $155M in strategic growth financing led by FTV Capital, announced September 2. It calls itself the money movement platform of choice for fintechs, lenders and platforms.

The round came with a second announcement that matters more than the amount. TabaPay intends to acquire Transact Bank, an OCC-chartered bank in Denver, and to operate it under a newly registered bank holding company. The company expects that deal to close in the fourth quarter, subject to regulatory approval, which puts a dated compliance and integration workload on the other side of it.

HiddenLayer, Austin

HiddenLayer raised a $100M Series B led by Delta-v Capital, announced September 2. The company sells security tooling for AI models and agents, and says its recurring revenue grew more than tenfold in twelve months across banking, insurance, pharma, airlines and US defence customers.

Its stated plan for the money is to deepen the enterprise platform, including runtime security for agents and a new product for securing AI coding agents. A tenfold revenue year followed by a platform build is usually a hiring year too.

DivergeIT, Torrance

DivergeIT announced a strategic investment from M|C Partners on September 3. The amount was not disclosed. The company describes itself as a managed IT and managed security services provider serving mid-sized businesses and enterprises nationwide.

This is the entry on the list most likely to change somebody else's quarter. The stated purpose of the investment is to make DivergeIT a platform for acquiring other managed service providers, so a competitor of theirs is now a target, and every acquisition brings an integration project with it.

What did not make the list

The largest number of the week is not above. A private AI infrastructure company was reported by Bloomberg on September 3 to have raised more than $3 billion at roughly a $30 billion valuation. That is a real fact from a serious source, and it is a different kind of fact from the five above, which the companies and their investors announced themselves. Worth knowing, harder to cite.

Two other items were circulating in funding feeds this week carrying this week's dates. One was a round announced in June 2025. The other was announced on August 11. Neither is a small distinction. A round from last year sends you into a company that has already assigned the money and picked its vendors, and none of that is visible from the headline, which is why the date and the source sit next to every entry above.

Which signal types are worth watching, and how long each one stays useful, is the subject of our guide to B2B buying signals. What a round does and does not tell you about a company's next quarter is covered in what a funding round actually tells you. And when the company in a funding headline turns out not to be the company that raised, the reason is usually one of five shapes.

This list came out of the funding signals in Leadalise, which watches a market you define and links every signal back to its public source. The pricing page lays out where a small team can start.
