MenuSAAS - What basic server architecture should we go for?
Answers
I think you're not fully embracing the lean startup methodology.
Is your SaaS handling some operations that are a matter of life and death or critical mission thing for an organization?
if the answer is No start with simplest option and do a soft launch and invite some carefully selected (50) beta testers.
Get the service going and gather feedback as much as possible. Then when you're at version 1.5 or 2.0 you'd know the problem you're solving a lot better.

PaaS is probably your best bet if you want to avoid hiring someone to manage things. Even managing two servers can eat up huge portions of your time — especially if these are new waters for you.
PHP/MySQL put you at a little bit of a risk, performance-wise, so be sure to keep an eye on resource usage.
In my current role, I'm putting WordPress sites up against thousands of concurrent users, so while the exact usage probably isn't the same, the tech stack is similar.
I'd probably do something like this (pretty much what I use): a Rackspace setup that can automatically scale when traffic spikes, with New Relic to keep an eye on performance and leaks in the app itself, and probably nginx/Varnish to try and keep the load off the servers in the first place (assuming any part of your app is cacheable).
A stack like that is not cheap compared to free, but it's cheap compared to a full-time ops engineer or spending a Friday/Saturday night trying to self-diagnose bottlenecks.
Good luck!
Take a look at Google Compute Engine. You'll pay by the drink, metered on your resource usage. Infrastructure cost drop drastically and you'll be on "GOOGLE's" gear / cloud. As an example, take a look at GetCloudCenter.com - the portal is running on GCE using LAMp servers, PHP, not sure about the DB side of things. They offer a demo portal to spin up and sell DaaS. Best of luck!
Clarity about the requirements of the service design should inform how you select the best platform deployment model now and in the future.
The Service Design should encompass 1) Availability Requirements, 2) Performance Requirements and 3) Scalability Requirements. Availability Requirements can be expressed in terms of acceptable number of downtime hours per year, Performance Requirements can be expressed in terms of maximum required transactions per second, and Scalability can be expressed in terms of the degree of linearity in adding additional peal transactional capacity to the system.
Implementing these service design requirements using a PAAS approach will require having significant technical expertise on staff. A different and more flexible option to consider would be to use an infrastructure-on-demand approach as currently being offered by Amazon Web Services (AWS).
AWS would allow you to deploy your preferred technology stack at an initially smaller cost commitment level and then scale up both the transactional capacity and redundancy as the build out of your business model warrants.

Does anyone know of a good SaaS financial projection template for excel/apple numbers?
Here is a link to a basic model - http://monetizepros.com/tools/template-library/subscription-revenue-model-spreadsheet/ Depending on the purpose of the model you could get much much more elaborate or simpler. This base model will help you to understand size of the prize. But if you want to develop an end to end profitability model (Revenue, Gross Margin, Selling & General Administrative Costs, Taxes) I would suggest working with financial analyst. You biggest drivers (inputs) on a SaaS model will be CAC (Customer Acquisition Cost, Average Selling Price / Monthly Plan Cost, Customer Churn(How many people cancel their plans month to month), & Cost to serve If you can nail down them with solid backup data on your assumption that will make thing a lot simpler. Let me know if you need any help. I spent 7 years at a Fortune 100 company as a Sr. Financial Analyst.BD

Can a WordPress site be converted into an iOS app?
Be careful when simply wrapping things into a mobile app. This can backfire on you and you could be presented with some very harsh edge cases. PHP isn't going to be encapsulated so much as the HTML/CSS/JavaScript. So keep in mind your mobile application could likely be in a position of requiring an online connection to work (because it must interface with your existing hosted WordPress site). This could also mean your hosting solution needs to be evaluated to ensure you can handle any increased traffic (and those traffic patterns could be different when coming from a mobile app that perhaps loads things the user doesn't see right away, accesses content that may not be cached, etc.). You want to ensure your server doesn't go down because then your mobile app would be "down" as well. That said... Things like Phonegap (web views) are a wonderful idea for utility apps because the performance is good enough for those (and hey even some games) and they end up being easily ported across many mobile operating systems. I would look into Phonegap, Appgyver (a new and totally awesome one because parts of it will utilize the native OS and your app will feel more responsive), Appcelerator Titanium, and perhaps even the new Famo.us one. Also take a look at the Ionic Framework for some further ideas about mobile UI and what you can do with these web view style apps.TM

Freemium v.s. free trial for a marketplace?
It depends on a number of factors but I'd boil it down to two key things to start: 1) What is your real cost to provide a free plan or trial? 2) Who exactly is your customer and what are they used to paying and who and how do they pay today? When you say "online workforce marketplace" it sounds as though you're placing virtual workers. If that's the case, or if you're paying for the supply side of the marketplace, the question is how much can you subsidize demand? Depending on where you're at in the process, I'd also question how much you can learn about the viability of your marketplace by offering a free version, assuming again, that free is actually a real cost to you. I was part of a SaaS project that started charging people for early access based mostly on just a good landing page (we clearly stated they were pre-paying) and were amazed at the response. I've also run a SaaS product that offered free trials and realized that the support costs and hand-holding and selling required to convert from free trial to paid wasn't worth it, this despite the product's significant average ARR. You might be better off providing a "more information" sign-up form (to capture more leads) and let them ask for a free trial while only showing your paid options. I've been amazed at the lead capture potential from a simple "have questions? Click here and we'll contact you" This is all the generalized advice I can offer based on the limited information I have, but happy to dive-in further if you'd like on a call.TW

How should we plan a well-executed SaaS product launch to an existing customer base?
I'm a product developer, startup veteran, and advisor to SaaS companies. Hopefully you've been already developing this new product with input from your existing customers, letting them beta test it and give feedback. (If not, my advice is to STOP immediately and get enough pilot customers involved to be sure that you're delivering something really valuable to them, that works the way they expect it to work, is easy to understand and get started with, etc.. The last thing you want is to do a big splashy launch of a product that is D.O.A. because you built what you assumed the customers wanted instead of they actually demonstrated that they wanted.) OK, so let's assume that you've got customers in the loop. Interview the heck out of them. Really understand how they use the product, why they use the product, what makes it valuable to them, what they can do with it that they couldn't do before, etc. If the product's not done enough for them to be best testing it yet and getting results, at least get some insights into how they see themselves getting results from it. How does it/will it change their lives? As you do this, be on the lookout for things that really resonate. Emotional language, for example. "It's such a relief that I don't have to worry about sending invoices manually anymore." (or whatever pain it is that your software solves) Also look for (and try to elicit) specific result statements: "This new software saves me [or is going to save me] 15 hours a week. Now I can spend that time where I really want to, with my kids ( ... my cat ... my golf buddies ... )" You're doing this for three reasons: 1) This stuff makes for phenomenal testimonials; 2) it helps you come up with great ideas for pre-launch content; and 3) it generates *PURE SOLD GOLD* you'll use in writing the copy for your launch offer. OK, launch mechanics. There are people who teach huge long expensive courses on this stuff. I'll give you the Cliff's notes. While I haven't personally run a major product launch, I have been trained in the strategy and am very familiar with it. - Plan your launch period in advance. You might want to do a pre-launch sequence that lasts 1, 2, even 3 months depending on the magnitude of your product and how much effort you're willing to put into creating content for the launch. - Create some teaser content of interest to your customers who might want to buy this product. Offer to teach them something, or offer to give them a sneak-peak behind-the-scenes of your new product. - Send an enticing offer for this content out to your list. Get people who are interested in this content to sign up for it. This creates your launch email list. - Send your launch list weekly updates: development milestones, sneak-peak screenshots, videos, educational material, interviews with/testimonials from beta users, and so on. - You're not trying to sell here yet (not hard sell at least). Drop some hints that there is going to be a special offer when the product launches, just for special loyal customers like them. - Create at least three videos on topics that are really, really interesting to your prospective customers... not necessarily about your new product itself, but teach them about what they can achieve with it, or what others have achieved with it already. As you publish these videos, send the link out to your launch list. - Also send out an offer to see these videos to your main list, to entice more people to sign up for your launch list. - As you get closer to launch time, keep sending frequent updates to the pre-launch list, and send another email out to your main list to let them know that the product is launching soon, and that if they're interested in the special one-time-only launch pricing, they need to sign up for the "early bird list" (your launch list). - Send out a 24-hour notice that the launch is going to happen soon, and the launch pricing will only be available for a limited time (potentially, to a limited number of customers ... to increase scarcity and urgency). - I recommend that even if you plan to open the product up to all your customers that at launch time you limit it to a smaller number. This makes the inevitable post-launch gremlins less painful to deal with because you have fewer customers, and it motivates people to buy because they fear that they'll lose the opportunity to do so. You can open the product up to more people later... the delay will result in pent-up demand and easier sales. - Start the launch. Tell your early-bird launch list a few hours early, then tell your main list. Direct them to a web page with a video and long-form sales copy of your launch offer. - Send out 2-day, 1-day, 12-hour, etc. notices that the launch is ending soon and reminding people what they're missing out on if they don't act now. If you're offering a limited number of spots, tell people what percentage has already sold out. Remind people that if they're "on the fence" about this, that this is the time to make a decision. - Send out an email letting people know that the launch is over and thanking them for their support and their vote of confidence. Tell the people who didn't buy (or didn't get in) that you'll let them know that the product will be opening up for new registrations some time in the future. (You may get people sending you emails begging to be let in at this point, if your product is desirable and your marketing was executed well.) And, of course, you don't just have to promote your launch content to your existing customer list ... you can post it to social media (and encourage your customers to do so) to attract brand new customers into your world. If you'd like to go into more detail about launch planning for your specific product and market, I'd be happy to jump on a call and talk about ways to make this work for you.BB
